BACKGROU~D OF THE INVENTION
This invention relates to fabric softener compo-
sitions and to a method of sof~tening textile materials. More
particularly, it relates to fabric softening compositions having
resistance to the adverse effects of anionic detergent materials
and adapted to use in the repetitious but generally discontin-
uous laundering process which involves soiling, laundering,
rinsing, soiling, etc.
The use of fabric softening compositions in househGld
laundering operations to improve the softness or "hand" of
~ laundered textiles has become a widespread practice. These
! 20 compositions have for the most part been liquld fabric softener
compositions con$aining in a water vehicle a quaternary ammonium
salt oomponent having an affini'y for negatively-charged fibers
and having at least one lcng chain alkyl moiety of from 16 to
. ~ . . .

1~15
~0 carbon atoms. These compositions have been largely adapted
for use in the final rinsing bath of the home launderinq process.
It has been found that the treatment of textile materiais in
such manner improves the softness or feel of the treated
fabrics, prolongs the useful life of the textile materials and
reduces the tendency of the fabrics to accumulate electrical
charges.
The quaternary ammonium salts of the prior art
softener compositions, being cationic in form, have been considered
to be incompatible with aniQnic species. Thus, the prior art
has included numerous references`to the adverse effects of
anionic materials on quaternary ammonium softeners and to the
loss of potential benefits of such softeners. Such references,
and attempts to mitigate the effects of anionic compounds on
quatexnary ammonium softeners can be found, for example, in
U.S. Patent 3,003,954 to Brown (October 10, 1961); U.S. Patent
3,178,366 to Du Brow et al. (April 13, 1965); U.S. Patent
3,329,609 to Blomfield (July 4, 1967); and in Canadian Patent
818,419 (~uly 22, 1969). Inasmuch as the final rinsing bath
of an automatic washing machine usually contains traces of
anionic materials carried over from a preceding washing step,
i.e. the intermediate rinses usually do not remove all of the
cleaning or washing agents or water softeners, an incompati-
bility problem has been recognized. Moreover, the tendency
to employ higher levels of detergent active, e.g. anionic
surfactant, in no-phosphate detergent compositions has in
turn resulted in a greater concentration o~ anionic material
Q15
in the rinse than has normally been encountered.
It is an object of this invention to provide composi-
tions useful for imparting softness to fabrics.
It is another object of this invention to provide
fabric softener compositions containing quaternary ammonium
salts and which are compatible with anionic materials.
Another ob]ect of the invention is to Frovide fabric
softener compositions effective to impart softness to fabrics
in the presence of anionic compounds encountered in laundry
rinsing operations.
These and other objects of the invention will become
apparent from the description appearing hereinafter.
S~MARY OF THE INVEN~ION
The present invention is based in part upon the
discovery that fabxics can be improved in feel by treating
the fabrics in an aqueous rinsing bath containing residual
anionic materials and a fabric softener composition comprising
a cationic fabric softener compound and a minor amount of a
fatty soap of from 16 to 22 carbon atoms. In its composi-
tion aspect, the present invention provides an aqueous fabric
softener composition consisting essentially of:(A) from 2% to 15~ by weight of a cation-active fabric softening
- compound having from one to two straight chain organic groups
of from 8 to 22 carbon atoms,
; - 3 -
(B) from 0.5% to 4.0~ by weight of an alkali metal salt of a
fatty acid of from 16 to 22 carbon atoms;
(C) from 0 to about 2% by weight of an emu~ifier selected from
the group consisting of (l) the condensation product of l
mole of alkylphenol wherein the alkyl chain contains from
about 8 to about 18 carbon atoms with from about l to about
lO0 moles of ethylene oxide, (2) the condensation product of
l mole of an aliphatic alcohol wherein the alkyl chain contains
from about lO to about 24 carbon atoms with from about 1 to
about 100 moles of ethylene oxide, (3) polyethylene glycols
having a molecular weight of from about 1400 to about 30,000,
and (4) mixtures thereof; and
; (D) the balance water.
In its method aspect, the present invention provides
a method of imparting softening properties to washed textiles
~hich comprises treating previously-washed textiles in an
aqueous rinsing bath containing minor amounts of anionic
compounds from said previous washing and an amount effective
to sof~en the fabrics of a composition hereinbefore defined.
The fabric softening compositions of this invention
provide softening properties to treated textiles notwithstanding
the presence of residual anionic compounds carried over into
the rinse from a previous detergent washO At lcw levels of
softener agent usage, the presence of soap permits an improved
level of fabric softening which could not be obtained from the same
composition free of the soap component or rrom 2 COmp~si~iOil
containing additional softener agent in place of ine soap.

D~T~ DESCRIPTION 0~ T~ JNV~NTION
The cation-active organic fabric-softener compounds, ~
which are the principal fabric-softening components of the
compositions of the in~ention, are known fabric-softening
compounds. Generally, these comprise cationic nitrogen-
containing compounds such as quaternary ammonium compoun~s
and amines and have one or two straight-chain organic groups
of ~at least eight carbon atoms. Preferably, they have one or
two such groups of from 12 to 22 carbon atoms. Preferred
cation-active softener compounds include the quaternary
ammonium softener compounds corresponding to the formula
r
LR1 \ R3
wherein R is an aliphatic group of from 12 to 22
carbons; Rl is an aliphatic group having from 12 to 22 carbon
atoms; R2 and R3 are each alkyl groups of from 1 to 3 carbon
atoms; and X is an anion selected from halogen, acetate
phosphate, nitrite and methyl sulfate radicals.
Because of their excellent softening effic~cy and
! ' ready availability, preferred cationic softener compounds of
the inveniion a--e the ~ial~ ;methyl am:~oni~m chioridec,
Q15
wherein the alkyl groups have from 12 to 22 carbon atoms and
are derived from long-chain fatty acids, such as hydrogenated
tallow. As employed herein, alkyl is intended as including
unsaturated compounds such as are present in alkyl groups
derived from naturally occurring fatty oils. The term "tallow"
refers to fatty alkyl groups deriv~ed from tallow fatty
aclds. Such fatty acids give rise to quaternary softener
compounds wherein R and Rl have predominantly from 16 to 18
carbon atoms. The term "coconut" refers to fatty acid groups
from coconut oil fatty acids. The coconut-alkyl R and R
groups have from about 8 to about 18 carbon atoms and
predominate in C12 to C14 alkyl groups. Representative
examples of quaternary softeners of the invention include
tallow trimethyl ammonium chloride; ditallow dimethyl aml-nonium
chloride; ditallow dimethyl ammonium methyl sulfate; dihexadecyl
dimethyl ammonium chloride; di(hydrogenated tallow) dimethyl
ammonium chloride; dioctadecyl dimethyl ammonium chloride;
dieicosyl dimethyl ammonium chloride; didocosyl dimethyl
ammonium chloride; di(hydrogenated tallow) dimethyl ammonium
methyl sulfate; dihexadecyl diethyl ammonium chloride; dihexa-
decyl dimethyl ammonium acetate; ditallow dipropyl ammonium
phosphate; ditallow dimethyl ammonium nitrite; di(coconut-
alkyl) dimethyl ammonium chloride.
An especially preferred class of quaternary ammonium
softeners of the invention correspond to the formula

wherein R and Rl are each straight chain aliphatic groups of
from 12 to 22 carbon atoms and X is halogen, e.g., chloride.
Especially preferred are ditallGw dimethyl ammonium chlorlde
and di(hydrogenated tallow-alkylj dimethyl ammonium chloride
and di(coconut-alkyl) dimethyl ammonium chloride, these
compounds being preferred from the standpoint of excellent
softening properties and ready availability.
Suitable cation-active amine softener compounds are
the primary, secondary and tertiary amine compounds having
at least one straight-chain organic group of from 12 to 22
carbon atoms and 1,3-propylene diamine compounds having a
straight-chain organic group of from 12 to 22 carbon atoms.
` Examples of such softener actives include primary tallow
amine; primary hydrogenated-tallow amine; tallow 1,3-propylene
diamine; oleyl 1,3-propylene diamine; coconut 1,3-propylene
diamine; soya 1,3-propylene diamine and the li~e.
` Other suitable cation-active softener compounds
herein are the quaternary imidazolinium salts. Preferred
salts are those conforming to the ~ormula

wherein R6 is an alkyl group containing from l to 4, preferably
from 1 to 2, carbon atoms, R7 is an alkyl group containing from
1 to 4 carbon atoms or a hydrogen radical, R8 is an alkyl group
containing from 8 to 22, preferably at least 15, carbon atoms,
R5 is hydrogen or an alkyl group containing from 8 to 22, pre-
ferably at least 15, carbon atoms, and X is an anion, prefer-
ably methyl sulfate or chloride ions. Other suitable anions
include those disclosed with reference to the cationic quater-
nary ammonium fabric softeners described hereinbefore. Partic-
--ularly preferred are those imidazolinium-compounds in which
both R5 and R8 are alkyl groups of from 12 to 22 carbon atoms,
; e.g., 2-heptadecyl-1,1-methyl 1(2-stearoylamido)ethyll
imidazolinium methyl sulfate.
Other cationic quaternary ammonium fabric softeners,
which are useful herein include, for example, alkyl (C12 to
C22)-pyridinium chlorides, alkyl (C12 to C22)-alkyl (Cl to C3)-
morpholinium chlorides, and ~uaternary derivatives of amino
- acids and amino esters.
The cationic fabric softeners mentioned above can
be used singly or in combination in the practice of the
present invention. The cationic fabric softener comprises
from about 2% to about 15~ by weight of the total composition.
If more than about 15% is used, product stability problems
may occur, e.g., thickening and the possible formation of an
undesired gel and if less than about 2% is used, the softener
will be too dilute and desired softening of the fabrics will
, not be achieved when conventional amounts of the composition are
- -- 10 --
~. .
Q~5
added to the wash water. Within the above range, the actual
amount of fabric softener which is contained in the composi-
tion depends upon the desired usage concentration of the
composition in a laundering process. A desired concentration
of the fabric softener in the washing solution is from about
25 ppm to about 100 ppm. ~o achieve the desired results
of the present invention the preferred range of cationic fabric
softener is from about 2.5% to about 6% by weight of the
total composition.
! The alkali metal soap component suitable for use
in the compositions of the present invention include the
sodium and potassium soaps of higher fa~ty acids of from 16
to 22 carbon atoms or mixtures thereof. These soaps can be
incorporated into an aqueous cationic fabric softening compo-
sition with the provision of a composition which still effec-
tively softens fabrics in a laundry rinsing cycle containing
residual anionics. Whereas such soaps can be compatibly
combined with cationic softeners, soaps of fatty acids having
less than 16 carbon atoms tend to mitigate the fabric-softening
effects of the cationic softener.
Commercial soaps are generally based upon mixtures
of fatty acid compounds obtained from natural sources such as
tallow, coconut oil, palm kernel oil or babassu kernel oil;
other com~ercial soaps are s~thetically manufactured to
simulate the fatty acids from natural materials such as tallow.
Soaps from any of these commercial sources can be suitably
employed so long~as they cont~in or are altered or modified
-- 11 --
``` 1~1~15 "
to contain at least 50%, and pre~erably at least 80~, by
weight of fatty acids having from 16 to 22 carbon atoms.
Thus, tallow soaps which include the sodium or potassium
salts of the mixtures of fatty acids derived from tallow
can be suitably employed. Tallow soaps predominate in
C16/C18 fractions and can be suit~ably employed in a
cationic-containing fabric-softening composition. In
contrast, coconut soaps, which predominate in C12/C14
fractions, mitigate the softening effects, for example, of
quaternary ammonium softener and are not suitable herein.
~" .
It will be appreciated that fatty acid soaps derived from
mixtures of natural fatty acid sources can be employed,
.,
where desired, so long as the resulting soap mixtures predo-
minate in soaps of C16 or higher fatty acids as described
~;-,15 hereinbefore. A preferred soap mixture is a tallow/coconut
soap blend of proportion 90:10. This mixture is preferred
~, from the standpoints of providing desirably optimum perfor-
mance and aesthetic characteristics.
The term "tallow" as used herein refers to a
` 20 mixture of soaps having an approximate chain-length distri-
? bution of: 2% C14; 32% C16; and 66% C18~
~he term "coconut" as used herein in connection
with soap or free fatty acid mixtures refers to materials
; having an approximate carbon-chain length distribution of:
2 5 8% C ; 7% C10; 48% C12; 17% C14; 9% C16; % 18
The amount of alkali metal soap employed to provide
- 12 -
effective resistance of the softener to the adverse effects
of anionic substances will depend on such factors as the
particular softening agent employed, the kind of soap, the
nature of the anionic substance and the desired viscosity or
physical appearance. As little as 0.5% of the soap based on
the weight of composition may be enough in some instance,
whereas up to about 4% of the`soap may be required in
others. The relative proportions of the cation-active fabric
softener compound and soap will be based more on physical
stability considerations than on performance considerations.
While amounts of fabric sqftener and soap components within
the ranges hereinbefore defined will permit the preparation
of softening compositions having resistance to the residual
anionics in a rinsing operation, certain ratios will be
preferred to assure that the hydrophilic/lipophilic balance
allows for the provision of a composition of stable physical
form. Thus, compositions containing, for example, distearyl
dimethyl a~monium chloride and alkali metal 90/10 tallow/coconut
soaps, respectively, in relative weight proportions of about
1:1 or about S:1 are preferred. These compositions are uniform
in appearance and do not separate into discrete phases. Fabric
softening effects are o~served notwithstanding the admixture
of both cationic and anionic substances. The percentages of
fabric softener and soap may be adjusted within the abo~7e
defined limits to suit the requirements of each case and to
combine softening and stability effects.

The compositions of the invention can be for~,ulated
in a convenient manner by admixture of the softener and soap
components and addition to water. A preferred method of
preparing the compositions involves the preparation of an
aqueous soap solution and addition to an aqueous dispersion
of the softening agent. It hàs been found that the admixture
of aqueous solutions of softening agent and soap permits the
preparation of a uniform, homogeneous composition having a
pleasing pearlescent appearance. The composition is free of
undesirable greasy or flocculent precipitate. While applicant
does not wish to be bound by any precise theory as to the
mechanism by which a uniform and homogeneous composition is
obtained in contrast to the greasy flocculent precipitate
expected from the prior art teachings regarding cationic/
anionic interactions, it is believed that a water-soluble or
dispersible complex or mixed micelle may be formed when the
anionic substance is a higher fatty soap as hereinbefore described.
It has been discovered that the presence of soap in
the compositions of the invention, rather than having an
opposing or counteractive effect on the fabric substantive
softening agent, can contribute actively to the softening
function at low level usage of the complete composition.
Thus, an aqueous composition of the invention containing 2.5%
- i4 -
lll~Q15
ditallow dimethyl quaternary ammonium chloride and 2.5% of
sodium 90/10 tallow/coconut soap and added to the final rinse
of an automatic washing maching in an amount of one fluid
ounce provides a hi~her level of softening performance than is
obtained where one fluid ounce of fabric softener having 5%
of the quaternary compound is empl~oyed. The same softening
contribution is not observed with higher usage levels, e.g.
two fluid ounces, in which case the compositions of the inven-
tion will have their greater attraction to users who customarily
or habitually employ low le~-els of softening composition in
laundering oper~tions. The compositions of the invention are
additionally characterized by a pearlescent appearance which
may be attractive ~o users of fabric softening compositions.
The compositions of the invention will preferably
contain an emulsifying agent. Suitable emulsifiers which
can be utilized in the compositions of the present invention
include those selected from the group consisting of (1) the
condensation product of 1 mole of alkylphenol wherein the
alkyl chain contains from about 8 to about 18 car~on atoms
with from about 1 to about 100 moles of ethylene oxide.
Specific examples of these nonionics are the condensation
product of 1 mole of nonylphenol with 9.5 moles of ethylene
oxide; the condensation product of 1 mole of decylphenol with
40 moles of ethylene oxide; the condensation product of 1
mole of dodecylphenol with 35 moles of ethylene oxide; the
condensation product of 1 mole of nonylphenol with 1.5 moles
of ethylene oxide; the condensation product of 1 mole of tetra-
,
- 15 -
decylphenol with 35 moles of ethylene oxide; and the condensa-
tion product of 1 mole of hexadecylphenol with 30 moles of
ethylene oxide; (2) the condensation product of 1 mole of an
aliphatic alcohol wherein the alkyl chain contains from 10
to about 24 carbon atoms with from about 1 to about 100 moles
of ethylene oxide. Specific examples are the condensation
product of 1 mole of coconut alkyl alcohol with 45 moles of
ethylene oxide; the condensation product of 1 mole of tallow-
alkyl alcohol with 30 moles of ethylene oxide; the product
sold by Union Carbide Corporation under the trademark "Tergitol
15-S-9" which is the condensation product of 1 mole of secon-
dary alkyl alcohol with alkyl chain lengths of from 11 to 15
with 9 moles of ethylene oxide; and the product sold by Union
Carbide Corporation under the trademark "Tergitol 15-S-3"
which is the condensation product of 1 mole of secondary alkyl
alcohol with alkyl chain lengths of from 11 to 15 with 3 moles
of ethylene oxide; (3) polyethylene glycols having a molecular
weight of from about 1400 to about 30,000. For example, Dow
Chemical Company manufactures these nonionics in molecular
weights of 20,000, 9,500, 7,500, 4,500, 3,400 and 1,450. All
of these nonionics are wax-like solids which melt between
100F and 200F. Emulsifiers suitable for use in the composi-
tions of the present invention may also include (4) mixtures
of (1), (2) and (3) discussed above.
These emulsifiers function as solubilizing agents
to prevent precipitation and maintain excellent freeze-thaw
characteristics of the liquid compositions. These emulsifiers
- 16 -
. ~
further act as stabilizers to promote shelf stability and
maintain the desired viscosity. The emulsifiers are present
in the composition of the present invention from about 0 to
about 2% by weight, preferably from about 0.25% to about 1%.
If more than about 2% by weight is used no advantages are
achieved and product stability problems can arise. Small
amounts of emulsifier are usually necessary to achieve the
desired stability and freeze-thaw characteristics while main-
taining the desired viscosity of the composition.
! Miscellaneous materials such as optical brighteners
such as the anionic stilbenes, coloring agents, perfumes, and
other materials which are well known as constituents in fabric
softener compositions and which are compatible in the composi-
tions of the present invention can also be present in minor
amounts.
The following examples illustrate the manner in which
the present invention can be practiced. However, the invention
is not confined to the specific limitations set forth in the
examples, but rather, to the scope of the appended claims.
