FABRIC TREATMENT COMPOSITION 13 ~ 0 3 ~ ~
This invention relates to a fabric treatment composition
for treating fabrics during the rinse step of a fabric
laundry process, and to a method for using said
composition. In particular, the invention relates to a
fabric treatment composition comprising a fabric-
softening material, which is preferably a cationic
fabric softening material and an antimicrobial agent.
It is known that fungal growth can develop on fabrics
stored under certain physiological conditions, such as
in a humid atmosphere or where there is poor air
circulation. These growths can damage the fabrics by
causing them to discolour. The fabrics can also develop
an unpleasant smell. It has been found that the
discolouration or staining of the fabrics is difficult
to remove either by normal laundering or after treatment
with a strong bleaching agent.
It has previously been proposed (EP 86 423, Henkel KGaA)
to incorporate specific antimicrobial substances in
fabric treatment compositions.
We have now surprisingly discovered that benzimidazolyl-
alkyl-carbamates, when combined with fabric-softening
materials into a fabric treatment composition, are
particularly effective in inhibiting fungal growth on
fabrics which have been rinsed with said fabric
treatment composition.
The incorporation of benzimidazolyl-alkyl-carbamates in
textile treatment compositions according to the
invention has also been found advantageous in that
benzimidazolyl-alkyl-carbamates are:
-~ 13403~8
1. effective against a wide range of micro-organisms,
particularly fungi;
2. active during the life of the product;
3. of low mammalian toxicity and non-toxic to humans
at the concentrations used;
4. colourless and odourless;
5. effective at low concentrations;
6. inexpensive and easy to apply;
7. resistant to sunlight;
8. not affecting fabric handle or strength;
9. compatible with water-repellent and flame-retardant
agents, dyes and other textile auxiliaries; and
10; do not sensitize the fabric to damage by light or
other influences.
Thus, according to the invention there is provided a
fabric treatment composition comprising a softening
material and a benzimidazolyl-alkyl-carbamate.
Preferably the softening material comprises a cationic
fabric softener.
Benzimidazolyl-alkyl-carbamates are well-known
fungicides for use in agriculture. It has also been
suggested in Japanese patent application 49 093 537
(Yoshitomi) to treat textiles with a composition
containing Me-2-benzimidazole-carbamate in a solvent.
This treatment, however, re~uires a separate processing
step for applying the benzimidazolyl-alkyl-carbamate and
a further separate processing step for removing the
undesirable solvent compound.
The benzimidazolyl-alkyl-carbamate as used in a textile
treatment composition of the invention is preferably of
the following formula:
~ N ~ 1O 13 4 0 3 .~ 8
R2 ~ / C - NH - C - O
wherein:
Rl is a Cl_4 alkyl, alkoxy or phenoxy alkyl; and
R2 is a Cl_4 alkyl, hydrogen, nitrogen or halogen.
Particular examples of suitable benzimidazolyl-alkyl-
carbamate substances are: benzimidazolyl-methyl-
carbamate, benzimidazolyl-ethyl-carbamate, 5-ethyl-
benzimidazolyl-ethyl-carbamate, benzimidazolyl-
isopropyl-carbamate, 4-ethyl-benzimidazolyl-isopropyl-
carbamate, 4-propyl-benzimidazolyl-isopropyl-carbamate,
4-butyl-benzimidazolyl-isopropyl-carbamate, 4-isobutyl-
benzimidazolyl-isopropyl-carbamate, benzimidazolyl-
ethylmethoxy-carbamate, 4-ethyl-benzimidazolyl-
ethylmethoxy-carbamate, 5-ethyl-benzimidazolyl-
ethylmethoxy-carbamate, benzimidazolyl-ethylethoxy-
carbamate, benzimidazolyl-ethyl-propoxy-carbamate,
benzimidazolyl-ethylphenoxy-carbamate, 4-ethyl-
benzimidazolyl-ethylphenoxy-carbamate and 5-ethyl-
benzimidazolyl-ethylphenoxy-carbamate.
The preferred benzimidazolyl-alkyl-carbamate is
benzimidazolyl-methyl-carbamate.
It is also possible to employ mixtures of different
benzimidazolyl-alkyl-carbamates.
Particularly preferred is the use of Intace B 350 (75%
carbendazim ex Intace), and Intace B 300 (100%
carbendazim ex Intace).
Other antimicrobial substances may be incorporated in a
fabric treatment composition according to the invention.
By antimicrobial substances are meant both antibacterial
and antifungal products. Examples of such material are
13~03.~8
.,
formaldehyde, halogenated phenols, nitrated mono- or
polyalcohols and antimicrobial surface-active tensides.
Particularly suitable for use in conjunction with
benzimidazolyl-alkyl-carbamates are tetra-methylthiuram-
disulphid, l-methylol-2-thiono-2-dihydrobenzthiazol,
N-dimethyl-N'-phenyl-(N'-fluordichloromethyl-thio)
sulfphamid and 3-isothiazolone compounds such as for
instance described in US 4,424,134. Generally, the
amount of additional antimicrobial substances in the
textile treatment composition is less than two times the
amount of benzimidazolyl-alkyl-carbamate.
The fabric softening materials may be selected from
cationic, nonionic, amphoteric or anionic fabric
softening materials.
Suitable amphoteric fabric conditioning material for use
in a composition according to the invention are fabric
substantive amphotheric materials forming a particulate
dispersion at a concentration of less than 1 g/l at at
least one temperature between 0 and 100~C. Preferably at
at least one temperature between 10 and 90 ~C, more
preferred between 20 and 80 ~C. For the purpose of this
invention a fabric substantive amphoteric material is
preferably an amphoteric or zwitterionic tertiary or
quaternary ammonium compound having either one single
long hydrocarbyl side chain or two long hydrocarbyl
chains. From these compounds the use of amphoteric or
zwitterionic ammonium compounds having two long
hydrocarbyl chains is particularly preferred for many
reasons including costs, ease of processing and better
stability and performance. Suitable amphoteric
materials are for example disclosed in EP 89200545.5.
In this specification the expression"hydrocarbyl chain
refers to linear or branched alkyl or alkenyl chains
optionally substituted or interrupted by functional

Preferably the amphoteric fabric substantive materials
are water insoluble and have a solubility in water at pH
2.5 at 20~C of less than 10 g/l. The HLB of the
amphoteric fabric substantive material is preferably
less than 10Ø

composition according to the present invention are
cationic materials which are water-insoluble in that the
material has a solubility in water at pH 2.5 and 20~C of
less than 10 g/l. Highly preferred materials are
cationic quaternary ammonium salts having two C12-24
hydrocarbyl chains.

to the invention include predominantly linear
polydialkyl or alkylaryl siloxanes in which the alkyl
groups contain one to five carbon atoms. The siloxanes
can be amido- or amino-substituted. When the siloxane is
amine-substituted the amine group may be quaternised.
These optional ingredients, if added, are each present
at levels up to 5% by weight of the composition.
The compositions according to the invention may take a
variety of forms. They may for example be liquids
containing an aqueous base.
Alternatively, the compositions according to the
invention may be in the form of a powder, creams,
pastes, a block or a tablet. Suitable types of blocks
and tablets are disclosed in European Patent
Specification EP-A-255 779 tUnilever).
When the compositions are in the form of liquid
products, the total level of the fabric softening
material and the benzimidazolyl-alkyl-carbamate is
preferably from 1 to 30% by weight. Based on the total
weight of the composition, the weight of the fabric-
softening agent is preferably from 1 to 20% and theweight of the benzimidazolyl-alkyl-carbamate is

1340358
paraffin and tallow alcohol. Other suitable materials
are disclosed in the European Patent Specification EP-A-
q~r~ . ~
' 255 779 (Unilever),r~ in~orporat~d horoin by rcfcrcnoc~ The compositions may
also contain an electrolyte to aid dispersion of the
cationic fabric-softening agent and the benzimidazolyl-
alkyl-carbamate, after the release inhibitor has ceased
to have effect, and an antifoam material. A suitable
antifoam granule may be of the type described in our
European Patent Specification EP-A-94 250.
In use, the compositions are preferably added to a large
volume of water to form a liquor with which the fabrics
to be treated are contacted. The liquor can be formed by
adding the fabric treatment composition to water during
the rinse stage of a hand-washing process.
Alternatively, the composition can be added by hand or
by way of an automatic dispensing device to rinse water
in the tub of a washing machine of the type which is
common in Europe, that is a machine in which the fabrics
are rinsed in a tub which is filled with rinse water,
agitated to achieve efficient rinsing and then drained.
Generally, the total concentration of the fabric-
softening agent and the benzimidazolyl-alkyl-carbamate
in the rinse liquor will be between 30 and 500 ppm.
Alternatively, the compositions, especially when being
in the form of a tablet or block, can be used in a
washing machine which is designed in such a manner that
the fabrics are rinsed in running water. With a machine
of this type, the fabrics will normally have been
previously washed in the same tub of the machine, or
they may be placed in the tub specifically for rinsing.
When previously washed, they will have at least some of
the wash liquor containing a detergent- active still
adsorbed on or otherwise associated with them, the
running water then serving to flush this wash liquor out
-
13~03S~
of the fabrics. The rinse water running into the tub
- will be substantially free of any detergent actives. The
composition can be added to the fabrics in the tub
before the rinse water flows into the tub,
simultaneously with the rinse water or part-way through
the rinse cycle.
The invention will now be illustrated by the following
non-limiting examples. In these examples, all parts and
percentages are by weight. Where commercially available
materials are referred to, the percentages quoted are
those of the active detergent therein.
13~03.~8
EXAMPLES 1-6
Aqueous compositions were prepared according to the
formulations in the following tables. The compositions
were prepared by co-melting the cationic fabric-
softening agent and benzimidazolyl-alkyl-carbamate at
800C. The co-melt thus formed was added to water at 80~C
to form a dispersion. In examples containing 2.5 and
5.0% carbendazim respectively, the benzimidazolyl-
alkyl-carbamate was post-dosed to a dispersion
containing the cationic fabric-softening agent.
The compositions were tested by the following method.
Two pieces of a 50/50 resinated polyester cotton fabric
and two pieces of a 100% cotton poplin fabric (each
measuring 20 cm x 20 cm) were washed at 50~C with 5
grams of a commercially available washing powder, Persil
Automatic, in a litre of water in a tergotometer. After
the wash liquor was separated, the fabrics were rinsed
twice with a litre of demineralised water. 2 ml of an
aqueous test composition was added to the second rinse.
After line drying, the treated fabrics were assessed, as
follows, to evaluate the microbial activity present.
Two pieces, each measuring 5 cm x 5 cm, were cut from
each piece of treated fabric. Both pieces were placed on
Petri dishes containing nutrient agar. 0.1 ml of an
inoculum of either Asperqillus niqer or Penicillium
spores was spotted onto the centre of each piece. Care
was taken not to allow the inoculum to spread onto the
surrounding agar. The inoculum concentration was 108
spores ml~l. The plates were incubated at 28~C and
evaluation of fungal growth assessed after 3 days.
..... .
13~0358
The scale used to assess fungal growth was:
0 = No growth on fabric.
10 = Very slight growth.
20 = Visible, light, patchy growth.
30 = Moderate growth on whole sample.
40 = Heavy growth on most of sample.
50 = Completely overgrown.
Owing to discolouration of the fabric, caused by spore
inoculum, a fungal growth score of 0 is never attained.
A score of less than 10 is indicative of no growth.
