~ETHOD FOR SIMULTANEOUSLY WASHING ~ND
SOFTENING FABRICS IN AN AUTOMATIC WASHER AND
CO~OSITIONS THEREFOR
Background of the Invention
-
This invention relates to methods for providing
a softened quality and control of static electricity
to fabrics being laundered during the laundering
process. More particularly, this invention relates
. to methods for providing these bene~its simultaneously
with the washing operation, where the washing process
employs conventional laundry detergent compositions.
Inclusive in these methods are the compositions employed
to achieve these benefits.
For years fabric softening and oontrol o~ static
electricity, in the context of a home laundry has been
accomplished by adding a liquid fabric softener,
during the rinse cycle of the automatic washer.
Addition of the fabric softener during the rinse cycle
rather than at the initiation of the was~ cycle was
required, ~ecause prior art fabric softeners which
are cationic in nature are chemically i~compatible
with conventional laundr~ detergent~, which ~re generally
anionic. Since these fabric softeners had to be added
during the rinse cycle, the washer had to be monitored
to determine ~hen the rinse cycle be~an, thus making the
process ~f adding the softener inconvenient for the
consumer.
To overcome the inconvenience of monitoring the washer
to determine when the softener should be added, various
attempts have b~en made to develop compositions which
are compatible with conventional detergents, so that
r ~
~-L86~5~
~ 2 -
the fabric so:Etener could be added along with a deter~
gent at the initiation of the wash cycle, without
sacrificing the beneficial effects of the sb~tener or
substantially interfering with the cleaning ef~iciency
of the detergent. The following are exemplary of the
types of so~tening and static con~rol compositions
which ha~e bæen developed for addition to a home laundry
at the initiation of ~he wash cycle~
U.S. Patent 3,936,537 to Baskerville Jr. et al
discloses detergent compatible fabric softening and anti-
static compositions containing conventional cationic
quaternary ammonium compounds or imidazolinium compounds
which are intimately mixed with organi~ dispersion
inhibitors to ~orm discrete particles. The organic
dispersion inhibitors keep the cationic compounds from
absorbing water and dispersing in the wash water ~here
they would react with the detergents, resulting in a
loss in detergency and the effectiveness oE the softener.
According to the patentees, the discrete softener con-
taining particles are deposited on the ~abrics duxing
the laundry operation, however, they impart their bene-
ficial properties when the fabrics are subse~uently
dried in an automatic dryer.
U.S. Patent 4,184,970 to Draper, Jr. also discloses
detergent compatible antistatic and fabric so~tenin~
compositions containing water-soluble neutral or alkaline
salts, prills of quaternary ammonium compounds intimately
muxed with organic dispersion inhibitors and water.
The quaternary ammoni~m compounds of these compositions
are complexed with anionic complexing components prior to
being prilled and then mixed with a dispersion inhibi~or.
According to the patentee, this insures that the ~uaternary
r~ r
6 4 $ 8
- 3
compounds remain non-reactive in the wash water of an
~utomatic machine S3 that they will be deposited directly
onto the fabrics in the machine without reacting with
the detergent. Although the particles of these composi-
tions are deposited on the fabrics during the wash,
their beneficial properties, of softening and static
control, are achieved in the dryer where the particles
are melted.
Other examples of so~tener compositions which are
compatible with anionic detergents are U.S. Patent
4,166,794 to Grey which discloses a compositions con-
taining a water-soluble peroxygen bleaching agent, a
cationic amine softener compound and ~later; and
Canadian Patent 1,060,604 to Johnson et al which also
discloses a composition containing an inorganic peroxygen
hleach and a cationic nitrogen containing softening
compound.
In contrast to the preceding prior art compositions,
the present invent.ion teaches the use of nitrogen con-
tai.niny softening agents without dispersion inhibitors
or peroxygen bleaching agents. Further, the present
invention is based on the use of relatively small amounts
o~ a primary, secondary, or tertiary amine or salts
thereof, rather thah on the conventional quaternary or
imidazolinium nitrogen containing so~tening compounds.
Summary of the Invention
It is an object of the present invention ~o provide
a method for simultaneously washing, softening and con-
txolling static electricity in fabrics being laundered
in an automatic washer. It is a further object of this
invention to provide compositions which are capable of
achieving these results of softening and controlling
static electricity simultaneously with the washing process.

It is yet a further object of this invention to
pxovide compositions for softening and controlling
static electricity which are compatible with conven-
tional anionic detergents; thus permitting the addition
of these compositions to a washer at the initiation
of a wash cycle. It is yet an even further object of
the present invention to accomplish softening and
static electricity control with relatively minor
amounts of a softening agent.
Thus the present invention provides a process of soften-
ing fabrics in an automatic washer during the wash cycle of
the automatic washer which comprises the steps of: (a)
adding a premeasured amount of a conventional laundry deter-
gent and fabrics to be laundered to the washer; (b) acti-
vating the washer so that the tub of the washer fills with
water; (c) adding an effective amount of: (i) a granular
material containing a mixture of an adjuvant and a particle
nitrogen containi.ng compound having a particle size of less
than 420 microns and said nitrogen containing compound being
selected from the group consisting of primary amines,
secondary amines, tertiary am.ines, and the acetate, sulfate
or hydrochloride salts thereof~ wherein said amines and
their salts have at lea.st one straight chain organic radical
of between 8 and 22 carbon atoms and wherein the ratio of
adjuvant to nitrogen containing compound is from about
15:1 to about 2:1; or (ii) an aqueous based composition
having a pH of less than 7 and containing a nitrogen con-
taining compound selected from the group consisting of the
acetate, sulfate, and hydrochloride salts of primary,
secondary, or tertiary, amines having at least one straight
chain organic radical of between 8 and 22 carbon atoms; and
(d) operating the washer through all of its cycles.
In another embodiment the present invention p.rovides a
fabric conditioning composition adapted to condition
fabrics in an automatic washer comprised of: (a) an
adjuvant selected from the group consisting of sodium

-~&~
- 4a -
sesquicarbonate, sodium horate decahydrate, sodium carbonate,
sodium sulfate, sodium tripolyphosphate, sodium silicate,
trisodium nitrilotriacetate; (b) an effective amount of a
particulate nitrogen containing compound selected from the
group consisting of primary arnines, secondary amines,
tertiary amines, mixtures thereof, and their acetate, h~dro-
chloride and sulfate salts, wherein said nitrogen co.ntaining
compounds have at least one straight chain organic radical
of between 8 and 22 carbon atoms, and having a particle size
of less than 4~0 microns; wherein the weight ratio of
adjuvant to nitrogen containing compound is from about 15:1
to about 2:1.
In still a further embodiment the invention provides a
laundry detergent composition comprising: (a) from 0.5 to
about 20~ by weight of a detergent compound selected from the
group consisting of anionic surfactants and mixtures of
anionic and nonionic surfactants, and (b) from 99.5 to about
80~ of a fabric conditioning composition adapted to condition
fabrics in the wash cycle of an automatic washer consisting
essentially of: (i) an adjuvant selected from the group of
sodium sesquicarbonate, sodiurn borate decahydrate, sodium
carbonate, sodium sulfate/ sodium tripolyphosphate, sodium
silicate, trisodium nitrilotriacetate/ and (ii) a particulate
nitroyen-containing compound selected from the group con-
~5 sisting of primary amines, secondary arnines, tertiary arnines,and mixtures thereof, and their acetate t hydrochloride and
sulfate salts, wherein said nitrogen-containing compounds
have at least one straight chain organic radical of between
8 to 22 carbon atoms, and have a particle size of less than
420 microns, the weight ratio of adjuvant to nitrogen-
containing compound being from about 15:1 to about 2:1.

- 4h -
The present invention is based on the discovery
that nitrogen containing compounds of the primary,
secondary, or tertiary amine type which are in a
particulate form having a particle size of below about
420 microns can be added to an automatic washer at
the beginning of the wash cycle along with conventional
anionic detergents. In addition to adding these
nitrogen containing compounds directly to the ~lasher
in particulate form, it has been found that aqueous
based solutions having a pH of less than 7 and con-
taining certain salts of primary, secondary, or
tertiary amines can be added to the washer at the
initiation of the wash cycle. Due to the alkalinity
of the wash water in the machine, there will be a
reaction which causes the nitrogen containing compounds
to precipitate out of solution. The resultin~ precipi-
tate is in a particulate form having a particle size
of less than 420 microns.
When added either directly in a particulate form or
in an ~queous based solution which will react to form
a precipitate of the requisite particulate form, these
compositions will be deposited on the fabrics being
laundered to impart both a softening effect and a
reduction in the static charges on the fabrics being
~ . r ~ 6~
-- 5
laundered~ It has been found that only relatively
minor amounts of these nitrogen containing compounds
need be used to produce the desired effect. This,
coupled with the nature of the material being used
and its particulate form, results in a minor effect
on detergency.
This invention encompasses a method of simultaneously
cleaning, softening and providing antistatic benefits
to fabrics which comprise the steps of adding to an
aqueous laundry bath at the beginning of a wash cycle,
fabrics, a conventional anionic detergent, and an effective
amount o~ a composition of the instant invention.
Also encompassed by this invention are the composi-
tions employed in this process these are:
(a) Compositions which are comprised of an adjuvant,
and à nitrogen containing compound
which can be a primary, secondary ox tertiary amine
or their acetate hydrochloride, or sulfate salts or
mixtures thereof; wherein said nitrogen containing
compound having at least one straight chain organic
radical of between 8 and 22 carbon atoms; wherein said
nitrogen containing compounds have a particulate form
with a particle size of less than about 420 microns;
and wherein the ratio of adjuvant to nitrogen containing
.25 cornpound is from about 15:1 to about 2:1; or
(b) Compositions which are aqueous based with a p~
of less than 7 and which contain a nitrogen containing
cornpound selected from the group consisting of the
acetate,sulfate and hydrochloride salts of primary,
secondary, and tertiary amines having at least one
- 6 -
straight chain organic radical of between 8 and 22
carbon atoms.
Detailed Description of the Preferred
Embodiments
In accordance with the present invention, fabrics
to be laundered are added to an automatic washer
along with a con~entional laundry detergent. The washer
is then actuated so that its tub fills with water.
Once this occurs, a composition of the present invention
is added. After this addition, the washer continues to
operate through all of its cycles.
The instant compositions can be added in two different
physi~al forms as either an aqueous based solution having
a pH of less than 7 or as a solid granular material.
Regardless of which form is used, the ingredient in each
which is responsible ~or imparting the desired soEtening
and static electricity control is one of the nitrogen
containing compounds described below. However, it
should be noted that in the liquid form only salts of
these compounds can be used, for only the salt form
will go into solution.
The granular form of these compositions is comprised
of a nit~ogen containing compound having a specified
particle size and an adjuvant which is chemically inert
with respect to the nitrogen containing compound and
prevents the individual particles of these compounds
from caking up prior to use. ~urther the adjuvant also
may act as a perfume carrier, if perfume is added to
~he composition. These adjuvants are used in the
present invention in a weight ratio of 15:1 to about 2:1
~7
of ad~u~ant to nitrogen containing compound, using
more than a~out 15:1 will result in making the product
somewhat cumbersome to use, while using less than 2:1
will result in some caking. Optimal results will be
obtained by using from about 10:1 to about 5:1 of the
adjuvant to the nitrogen containing compo~md.
In the granular form of the instant compositions,
the nitrogen containing compounds are in a dry partieu-
late form, where the individual particles are less than
about 420 microns. Using particle sizes which are
greater tban 420 microns will ha~e a detrimental effect
on the softening and control of static electricity.
The preferred particle size for use herein would be
from about 15 microns to 420 microns. It is preferred
to use particles which are larger than 15 microns
in that smaller particles tend to be dusty and therefore
difficult to use. The most preferred particle range
of particle sizes for use herein is from about 5~
microns to a~out 150 microns. This range is particularly
advantageous from the standpoint of both handling and
effect on detergency.
In the liquid ~orm, the instant compositions are
aqueous based and contain only one of the salt forms
of the useul nitrogen containing compounds. The
liquid form is limited to the salts of the nitrogen
containing compounds~ since only the salts will form
solutions. In addition to the salts of the nitrogen
containing compounds, these solutions will contain a
small amount of an acid, which is the same as that used
to form the salt. The amount of the acid used should be
sufficient to maintain the pH of the solution below 7
and preferably, at around 6.5 and the amount oE the s~lt
r~
form of the nitrogen containing compound should be
sufficient to form a solution which contains from about
5% to about 15% and preferably 10% by weight of the
ni$rogen containing salt compound.
In accordance with the methods of the instant inven-
tion, the liquid form of the composition is added to a
washer after the laundry detergent and after the tub
of the washer is filled with t7ater. Since all conven-
tional laundry detergents contain alkaline ingredients,
. the pH of the wash water in the tub will be alkaline.
When an acidic liquid composition of this invention
is added to the wash water, a reaction will occur which
will cause the nitrogen containing compounds to precipi-
tate out o~ solution forming discrete particles with a
particle size of le5s than 420 microns.
The nitrogen containing compounds which are useful
in the present invention are the primary, secondary
or tertiary amines which have at least one straight
chain organic radical of 8 to 22 carbon atoms and
preferably 12 to 22 carbon atoms, and which are solid
at room temperature (approximately 25C) and are
capable o~ assuming a particulate form. Mixtures of
these compounds may also be used, along with the acetate,
hydrochlQride and sulfate salts of these amines.
Examples of useful primary, secondary, and tertiary
amines include primary hydrogenated tallow amine;
primary tallow amine; octadecylamine: hexadecylamine;
hydrogenated tallow amine; stearyl amine; tetra decylamine;
dicocoamine; di-(hydrogenated-tallow)amine; methyldi-
cocoamine; methyldithydrogenated-tallow)amine; dimethyl-
acetyl amine; and dimethyltetradecylamine. Examples of
useful amine salts are the acetate, hydrochloride, or
sulfate salts of any of the foregoing compounds. The
~ 9 ~
compounds which are preferred for use herein are
octadecylamine, octadecylamine acetate, hydrogenated-
tallow amine and hydrogenated-tallow amine acetate.
The adjuvants which are useful in the granular form
of the instant composition include, for example,
sodium sesquicarbonate, sodium borate decahydrate,
sodium carbonate, sodium sulfate, sodium tripolyphosphate,
sodium silicate, trisodium nitrilotriacetate.
In addition to the essential ingredients of both the
liquid and granular forms, compositions can also contain
dyes, perfumes, optical brighteners, enzymesl bacter-
iostats and bleaching agents. Further, the liquid form
of these compositions can contain an alcohol or other
viscosity modifier.
As formulated, these compositions both with and
without the additional optional ingredients would be
considered laundry additives. ~lowever, with the granular
forms of the instant compositions, it would be possible
to formulate a laundry detergent which would not only
clean but also provide static electricity control and
~oftening. Such a detergent could be ~ormulated by
mixing a conventional nonionic ox anionic surfactant
in a dry yranular form with the granular form of the
instant compositions.
By practicing t~e instant invention, beneficial
effects of both fabric softening and control of static
electricity can be achieved during the laundry process.
When compositions of this invention are added in a
particulate form or in a liquid forml the amount which
is efective to impart the desired benefits in a standard
size washer containing about 4 1/2 lbs Gf fabrics and
r~
~ .
- 10 - ~3L8~
17 gallons of water is from about 4 to about 25 grams
of nitrogen containing compound. Less than 4 grams
in a standard size washer will not provide the desired
benefits while using more than about 25 grams will not
S provide additional benefits. In a standard size
wash optimal results are obtained using about 7 grams
to about 14 grams of the nitrogen containing agent.
When delicate fabrics are laundered or smaller si~e
washes than standard are contemplated, the amount of
the nitrogen containing agent can be adjusted to provide
the desired benefit.
The granular form of the compositions of this inven-
tion can be prepared by dry blending a ni-trogen contain-
ing compound with an adjuvant. This blending is done,
however, after the nitrogen containing compound has
been prepared in the requisite particle size. The
techniques used to produce the desired particle size
include spray drying prilling, or micropulverizing
coupled with screening to separate out matter which is
too large.
The composition which results from mixing of the
particulate nitrogen containing compound with the
adjuvant is a free flowing powder which in accordance
with the methods of this invention is added to an auto
matic washer at the initiation of the wash cycle after
the wash tub has filled with ~Jater and after the
laundry detergent has been added to the washerO Althouyh
this method is preferred, these granular compositions
may also be dry blended with a detergent and added
prior to the tub being illed with water, or, these -
granular compositions can be added without being
blended with a detergent, again before the tub is filled
with water.
.&6~
The liquid form of these compositions is prepared
by adding a salt of one of the nitrogen containing
compounds to water and then adding a small amount of
the acid which corresponds to the salt, such as
acetic acid when the acetate salt is being added.
The amount of acid which is added to this composition
should be su~ficient to result in a pH of less than
7.
In accordance with the methods of the instant inven-
tion, the liquid form of these compositions is added
to the washer after the fabrics and detergent have
been added and the wash tub has been illed with water.
The following numbered Examples further illustrate
some embodiments of the invention in addition to those
described heretofore.
ExAMæ~E 1
Three sample compositions were made in accordance
with the present invention, Samples A, B and C, each
containing 10 grams of octadecylamine acetate (available
fro~ Armak Chemical Co. under the Trademark of ARMAC 18D~
having a particle size of between about 150 micxons to
ahout 420 microns and 28 grams of Borax (sodium borate
~ecahydrate). Each sample was then used in a test wash.
The test washes were each conducted using a standard
4 1/2 lb. load of laundry which consisted of cotton,
polyester and nylon fabrics~ The standard load was
added to a conventional size automatic washer along
with a presoiled cloth. A~ter these were added to the
machine, the machine ~7as allowed to ~ill with water.
Once the machine was filled with water, one cup of a

commercially available laundry detergent, TIDE (avail-
able fxom P&G), was added to the machine along with
one of the above described samples. The wash cycle
was then set for 10 minutes which was followed by a
rinse with water having a temperature of between 50F
and 60F. The wash water temperature used for each
of the test washes was varied and the temperatures
used are shown in the t~ble which follows.
After each test wash, the standard load and the
soiled cloth were dxied. The standard load was then
tested for softness, static electricity and static
cling, while the soiled cloth was tested for stain
removal.
In addition to the test washes conducted with the
~5 three samples, two control washes were conducted.
In the first control, a stand~rd load and a soiled
cloth wexe laundered using TIDE*alone. In a second
control, a standard load and a soiled cloth were also
laundered using ~IDE alone. However, after the wash
was completed in khe second control, the standard
load and the soiled cloth were dried with a typical
sheet type dryer added fabric softener product. The
sheet employed here was made from a non=woven fabric
which was coated with an imodazolinium nitrogen c~n-
taining compound, a nonionic surfactant release agent
and a fragrance. As with t~st washes A, B and C the
fabrics laundered in both control washes were tested
for softness, static electricity and sta~ic cling,
while the soiled clothes were tested fGr stain removal.
Static cling was rated in terms of slight, bad~
or none, where a bad cling rating represents two items

in the standard load being stuck together in a manner
requiring the items to be pulled apart. The static
electricity of the load was then determined using a
Faxaday Cage, each item in the load was tested for
static electricity and the scores or each item were
then cumulated to arrive at the static electricity
for the total load. To dete~mine softness, a panel
ranked the fabrics in the standard load on a scale of
1.0 to 5.0*,where a scoxe of 1.0 inaicates the best
score, or the softest fabric, while a score of 5.0 indi-
cates the least soft.
The percent cleaning achieved in each test wash
was determined by taking re~lectance readings on each
of the soiled cloths laundered in the test washes and
the soiled cloth washed in the control wash~ The reflect-
ance values of the soiled cloths laundered in the test
washes were then each divided by the refIectance value
obtained on the cloth laundered in the control wash.
These figures were then each multiplied by 100 since
the control was cons:idered to have 100% cleaning in that
only a detergent was used.
The results of these tests are given in the Table
below.
* In accordance with this test method the highest ranking number
or worst score for softness possible is equal to the total number
of test conditions evaluated. Therefore if 5 are evaluated the
worst possible score is 5, if 6 are evaluated the worst possible
score is 6.

From the foregoing results, it can be seen that
the compositions of this invention provide excellent
softening benefits and static electricity control when
compared to using detergent alone and also do not
significantly affect the cleaning power of the detergent.
EXAM2LE 2
Six test washes were conducted as described in
Example l; three using samples in accordance with this
invention and three control washes. The samples which
were prepared in accordance with the present invention
are described below. The first control wash was con-
ducted using only a commercially available detergent,
TIDE. The second using a dryer added sheet softener
as in Control 2 of Example 1, and a thira using a sample
which was a mixture of hydrogenated-tallow aliphatic
amine acetate and a quaternary ammoni~m compound
distearyldimethyl ammonium chloride (sold under trade
name Arosurf TA 100).
Sample A consisted of 14 grams of hydrogenated~
tallow aliphatic amine acetate ~available from the Armak
Chemical Co. under the trademark ARMAC HT~ having a
particle size of from about 150 microns to ab~ut 420
microns and 28 grams of Borax.
Sample B consisted of 12 grams of hydrogenated-
tallow aliphatic amine acetate having a particle size
of from about 150 microns to about 420 microns and

Again, as with Example 1, the test washes conducted
using a composition of the present invention provided
substantial softening effects while controlling static
electricity without a significant decrease in cleaning
when compared to the cleaning and softening results
obtained with the Cont.rol 1 or Control 2. Control 3,
although exhibiting some softening affect and not having
a deleterious effect on cleaning, is unacceptable in
that it provides only marginal control of static
electricity.
EXAMPLE 3
Five test washes were conducted in accordance with
the procedure described in Example 1 using the following
three samples prepared in accordance with the present
invention and the two control washes described in
Example 1.
Sample A consisted of 11 grams of a mixture of equal
parts of octadecylamine acetate and hydrogenated-tallow
aliphatic am.ine acetate having particle sizes of between
150 microns and 420 microns and 28 grams of Borax.
Sample B contained 10 grams of octadecylamine
acetate having a particle size of between about 150
microns to 420 microns and 28 grams of Borax.
Sample C contained 2 grams of hydrogenated-tallow
aliphatic amine acetate and 8 grams of octadecylamine
acetate; both ingredients having a particle size of
between about 150 microns and 420 micrcns, and 28
grams of Borax.
Control 1 used TIDE alone and Control 2 used TIDE

Again, as with the preceding Examples, test washes
conducted using compositions of the present invention
provided substantial softening and static control
benefits while only having a minor effect on the
detergency.
EXAMPLE 4
Six test washes were conducted in accordance with
the procedure described in Example 1. Four test washes
were conducted using samples in accordance with the
present invention and two control washes were conducted;
the ~irst using only a commercially available laundry
detergent, TIDE and the second using a laundry detergent
TIDE, and the dryer added softener, described in Example
1. The samples used were the ~ollowing:
Sample A contained 8 grams of octadecylamin~ acetate
having a particle size of between 150 to about 420
microns and 40 grams of sodium sesquicarbonate.
Sample B contained 7 grams of octadecylamine acetate
having a particle size of between 150 to 420 microns
and 40 grams of sodium sesquicarbonate.
Sample C contained 7.5 grams of octadecylamine acetate
having a particle size of between about 150 to 420
microns and 40 grams of sodium ses~uicarbonate.
Sample D contained 10 grams of octadecylamine acetate
having a particle size of between about 150 to 420 microns
and 40 grams of sodium sesquicarbonate.

EXA~LE 5
The granular form of the composition of the instant
invention could be dry mixed with the ingredients
commonly used in laundry detergents to achieve a
composition which could be added to an automatic washer
at the beginning of the wash cycle to simultaneously
