Nitroqen-free active ingredient com~onent in fabric
softener formulation~
The invention relates to alkoxylated natural oils and fat~
as ni~rogen-free active ingredient component in ~abric
softener formulations and to their us9 therefor. The
alkoxylated natural oils and fat~ may be u~ad both on
their own and in mixtura with conventional nitrogen-
containing cationic active ingredient components with and
without the addition of disper~ants, emulsifiers and/or
- solubiliser~.
It is known to use nitrogen-containing cationic compou~d~
a~ the sole active ingredient components ln fabric
softener formulation~. The active ingredient N,N-
distearyl-N~N-dimethylammonium chloride (VSDMAC~ u~ed over
many years in fabxic softener~ is, however, increa~ingly
being replaced, on account of its unfavourable aqua-
toxicity, by ~ubstitutes e.g., imidazoline derivative~
(see inter alia, ~uch a~, for example, US-A 4 762 685,
EP-A 0 199 383), quaternised fatty acid ester~ of
triethanolamine ~known as esterquats, see inter alia
US-A 4 830 771) or 2,3-dihydroxypropyl-1-trimethyl-
ammonium ~alt deri~atives (DE-A 27 28 841).
In the medium and long term, it is likely that nitrogen-
contaLning fabric softener active ingredient component~
will have to be replaced partially or completely by
largely nitrogen-free alternatives, inter alia, in YieW of
the possibility of nitrosamine formation. Said alter-
natives should be characterised by a high softening
potential, anti~tatic and rewetting properties and
advantageous ecotoxicological behaviour. DE-A 34 16 669
describes the use of crystalline layer silicates and
alkaline salts thereof as softening active ingredients in
detergents. A sLmLlar situation is described in
DE-A 23 34 899 and DE-A 33 12 774, which claim the u~e
of saponites, hectorites and montmorillonites as softenLng

active ingredients in detergents. Tha ~oft~ning ~ffact of
said substances is evidently based on their function as
cation exchangers and thu~ as water softeners. In ~oft
water, therefore, ~aid ~ubstance~ are ineffective.
The ob~ect of the invention i~ therefore to find nitrogen-
free active ingredient component~ which may be used a~ an
al~ernative to the ~ole use of nitrogen-containing fabric
~oftener active ingredient component~ or in combination
with ~aid components, if necessary after appropriate
emulsiflcation or di~persion and/or the addition of
solubili~ers. They should not only be miscible and
compatible with said suh~tances but al~o h~ve a
synergi~tlc effect, if po~sible, or alternatively exhibit
~often~ng propertie~ on their own.
The ob~ect 1~ achieved according to the invention by the
u~e of alkoxylated natural o~l~ and fats a~ nitrogen-frea
active ingredient component~ In principle, the oils and
fats which can be u~ed according to the invention as
starting material include all tri~lyceride~ and mixture~
thereof with free fatty acids/ mono- and/or diglycerides.
Alkoxylation may taXe plsce in accordance wlth
DE-A 36 17 657 and DE-~ 38 26 179.
The invention therefore relate~ to a nitrogen-free active
ingredient component for fabric ~oftener formulation~,
comprising alkoxylated natural fat~, oils and mix~urss
thereof with frea fatty acids, mono- and~or diglycerides.
The invention furthermoxe relates to the use of
alkoxylated natural fats, oils and mixtures thereof with
free fatty acids, mono- and/or diglycerides on their own
as nitrogen-free fabric softener active ingredient
component or in mixture~ with nitrogen-containing cationic
fabric softener active ingredient components and, if
nece~sary, dl~persants, emulsifiers and/or solubilisers.

quantity of fabric softener active ingredient.
Mixtures of variou~ alkoxylated natur~l ats t oils and

diglycerides may al~o be used.
Moreover, the mixing of various natural fats, oil~ and
mix~ure~ thereof with free fatty acids, mono- and/or

The following epoxides that can be used for alkoxylation
are mentio~ed by way of examples
Ethylene o~ide, propylene oxide, butylene oxideJ 2 methyl-
but-2-ene oxide, 3,3-dimethylbut-1-ene oxide, C6-C2,-
epoxides, styrene oxide, 1,2-epoxybutadiene~ 1,2-epoxy-
cyclohexene and glycidic ester3 and ether~. If more than
one epoxide i~ used, said epoxide~ may be reacted with the
fatty substances either successively or simultaneou~ly.
The proportion of cationic ni.trogen-containing fabric
softener active ingredients and mixtures thereof as fabric
2S softener actiYs ingredient component is 0 to 99~, prefer-
ably 20 to 80%, ba~ed on the total quantity of fabric

Descript~ion of the softenin~g efect test m_thod [triangle
The softening effect of the alkoxylated fat~, oils or
mixtures thereof with free fatty acid~ and/or mono- and/or
diglyceride~ or mixture~ thereof with cu~tomary fa~ric
~oftener active ingredient components was determined as
follows. a load of 72 terry towel~ (44 cm x 30 cm,
approx. 60 g, from WFX Te~tgewebe GmbH) wers washed once
by machine at 95 C with 100 g of a commercial heavy duty
d~tergent (PERSIL, Henkel), even if not all 72 towel~ ware
u~ed (for rea~on~ of uniform wear and tear), rinsed and
spun. ~here followed a wash cycle at 95 ~C without
deter~ent lncluding a rin~e and ~hort epin, ~o that clean,
damp towel~ containing about 2.5 time~ the~r dry weight of
water could be removed for manual ~oftening.
For a test plan as in Table A, in each ca~e 9 towel~ were
xin6ed in 9 rinsing liguor~ with the standard ~= S) and 9
towels were rineed in 9 rin3ing liquor~ with the test
substance (= T). To thi~ end, in each case 2 litre~ of
tap water and 0.00 or 0.35 g/l tandard (calc~lated a~
active substance) or a freely chosen amount of te~t
substance were predisper~ed in plastic bowl# and the damp
towels were left therein for 10 min. After 5 minutes the
towel~ were turned once. The rinsed towels were each spun
individually for 30 seconds and dried on the laundry

In each case, 3 towal~ in keyed form were placed before
the tes~ pPr~ons in accordance with the tes~ plan
according to Ta~le A ( triangle test). The tester~ ta~k
was to pick out the differently treated towel by ~en~ory
apprai~al.
If this was pos~.Lble, the tester noted down whether the
different towel felt ~ofter or hsrder. If at least 5 of
the 6 testers picked out the differently treated towel (T
in the case of testers 1 to 3, S in the case of te ter~ 4
to 6), there i~ a significant difference between the test
subs~ance and the standard according to DIN 10 951 with a
probability of mors than 95%. The result $8 expre~sed
: with the a~d of 3 figure~: the fir6t figure gives the
number of te~ter~ who found the towels treated with the
standard ~ofter or found those treated with tha te~t
substance hardex. The second f.igure give~ the nu~ber of
testers who found the towels treated with the ~t~ndard
harder or found ~hose treated with the test ~ubs~ance
softer. Finally, the third f.igure gives the number of
testers who, in view of the ~mall sensory differences
between the towels treated with the test substance or the
standard, were unable to determi.ne the differently treated
towel or did not give the correct an~wer.

Examination of the rew*tt n~ prop~rty
In accordance with DIN 53 924 (ri~e in height method),
rewetting te~ts were carri~d out in a simplified form on
; terry fabricO To this end, terry towels were treated with
the test substances in accordance with the method
described in the section "Description of the softening
ef fec~ test method" . After drying, strips 30 cm long and
8 cm wide were cut (in a crosswise direction) and
suspended vertically ~n a beaker filled with 500 ml of
25 deionised water. The depth of immer~ion of tha fabric wa~
1 cm.
In order to make the rise in height more discernible,
0.5 g of K2CrO~ was added to the water. The immer~ion time
was 5 minutes in each case. The water wa~ then removed
and the ris2 in height reached was m~a~ured. The rise in
height that followed without further addition of water wa~
mea~ured after 65 minutes.
The rise~ in height ascertained in respect of the terry
fabric treated with samples 1 - 47 from Example~ 1 - 10
are listed in Table 11. They are means of double

Explanation of the ri e in height re~ults:
In order to be able to clas~ify the test re~ults better,
the ri~es in height found for the 0 ~ample (terry fabric,
treated only with the commercial heavy duty deterqent
(PERSIL, Henkel) after 5 min.: 10.2 cm, after 65 min.:
: 18.5 cm) should be compared flr~t with those of ~ample
no~. 13 and 18 (treated wlth pure e~terquat, after 5 min.:
-~ 6.9 cm, after 65 min.s 12.2 cm), 23 and 28 ~treated with
pure 1, after 5 min.: 4.8 cm, af~er 65 min. 8.6 cm), 33
~treated with pure 2, after 5 min.: 6.0 cm, after S5 min.:
lO.0 cm) and 38 and 43 (treated with pure 3, after 5 min.:
3.9 cm, after 65 min.: 5.3 cm~. It can clearly be seen
that all the cationic nitrogen-containing fabric softener
active ingredient component~ or their ready-for-use
formulations examined cau~e ~ignificantly lower rises in
heiyh~ compaxed with the 0 ahmple, which i~ equivalent to
a greatly reduced rewetting capacity. ~he alkoxylated
natural fat~, oils and mixtures thereof with free fatty
acids, mo~o- and/or diglycerides do thi~ to a vary small

extent, or not at all, at a similar u~e concentration of
0.3 or 0.4 g per litre of rinslng liquor, a~ ~mple no~.
2, 3, 6, 7, 10 and 11 show by way of example. Terry
fabric traated with alko~ylated natural fats, oils and
mixtures thereof with free fatty acids, mono- and/or
diglycerides thus exhibit~ an excellent rewetting
capacity. If the alkoxylated natural fat-~, oil~ and
mixtures thereof with Pree fatty acid3, mono- and/or
diglycer1des are used in mixture with the abovementioned
cationic nitrogen-containing fabric softener active
ingredien~ components or the ready-for-u~e formulati~ns
thereof, the following i~ found, taking the rises in
height after 5 and 65 minutes into account: none of the
mixtures rerommended in ~xample~ 1 - 10 causes a reductlon
in the rises in height in comparison with ~he corre~-
ponding cationic ~ubstance6. There i~ frequently even a
substantial increase.
