FABRIC CARE COMPOSITION

Technical Field

This invention relates to fabric care compositions and to methods of treating fabric using the compositions or the polymeric materials they contain.

Background and Prior Art

The laundry process generally has several benefits for fabric, the most common being to remove dirt and stains from the fabric during the wash cycle and to soften the fabric . during the rinse cycle. However, there are numerous V4 disadvantages associated with repeated use of conventional oo laundry treatment compositions and/or the actual laundry process; one of these being a fairly harsh treatment of : fabric in the laundry process.

Fabrics can be damaged in several ways as a result of repeated laundering and/or wear. Fabric pilling and loss of fabric surface appearance e.g. fuzzing, shrinkage (or expansion), loss of colour from the fabric or running of colour on the fabric (usually termed dye transfer) are some of the common problems associated with repeated laundering.

These problems may occur merely from repeated hand washing as well as the more vigorous machine washing process.

Furthermore, problems relating to damage of fabric over time through normal use, such as loss of shape and increased likelihood of wrinkling are also significant.

* + WO 01/27232 PCT/GB00/03695

The present invention is directed towards alleviating one or more of the problems referred to hereinabove.

The principal advantage of the present invention relates to improving the surface colour definition of a fabric after multiple washings and/or to imparting pill and/or fuzz resistance to fabric during laundering. The invention can have further advantages in the treatment of fabric. For example, other aspects of the overall appearance of the fabric can be improved, such as a reduction in the tendency of the fabric to become creased and/or wrinkled.

Laundry detergent compositions containing polyamide- polyamine fabric treatment agents are described in WO 98/29530. The compositions are claimed to impart improved ) overall appearance to fabrics laundered using the detergent compositions, in terms of surface appearance properties such as pill/fuzz reduction and antifading. Laundry compositions containing polyamide-polyamine treatment agents of similar types are taught in WO 97/42287.

Laundry compositions containing polyamide-polyamine fabric treatment agents can exhibit increased dye pick-up (ie, increased dye transfer) and poor stain removal properties compared to other conventional laundry compositions.

US 5571286 (Connell et al) discloses certain polymers and prepolymers derived from polyoxyalkyleneamines and their use in a process for shrink-proofing wool. The treated wool may also have a softer handle than untreated wool. This document does not mention the treatment of cellulosic i fabrics or the problems of loss of fabric surface appearance that they can experience following laundering. Furthermore, it deals entirely with treatment of wool on an industrial scale and does not mention the application of the compositions to fabric in the context of laundering processes.

The present invention is based on the surprising finding that certain polymeric materials, including those described in US 5571286, can impart improved surface appearance to cellulosic fabrics. The polymeric materials can have the further advantage of reduced adverse side-effects, in terms of increased dye transfer and poor stain removal, for example, compared to certain compositions containing polyamide-polyamine fabric treatment agents.

Definition of the Invention . ‘

According to the present invention, there is provided the use of a fabric care composition to improve the surface colour definition of a fabric after multiple washings and/or to impart pill and/or fuzz resistance to fabric during laundering, wherein the composition comprises a polymeric : material which is capable of self cross-linking and/or of : reacting with cellulose together with one or more textile compatible carriers, wherein the polymeric material comprises one or more poly(oxyalkylene) groups having an end group which comprises one or more amino groups or derivatives of said amino groups, and wherein when the textile compatible carrier is water a further additive : suitable for use in laundry compositions is present. ; - = = = — — — —- =~ . _Fmended Sheet 28/03/2003 ,

Detailed Description of the Invention

The compositions of the present invention comprise a polymeric material which is capable of self cross-linking and/or of reacting with cellulose together with one or more textile compatible carriers, wherein the polymeric material comprises one or more poly (oxyalkylene) groups having an end group which comprises one or more amino groups Or derivatives of said amino groups.

LE] _ i. : ~. Amended Sheet 28/03/2003 —

The compositions of the invention have the surprising advantage of imparting wear resistance to fabrics, and thereby causing improved surface colour definition of the fabric after laundering, particularly after multiple washings. Furthermore, the polymeric materials contained in the compositions need not cause unacceptable dye transfer and/or stain removal problems.

The polymeric material which can be used in the present invention can be any of the polymers or prepolymers derived from polyoxyalkyleneamines that are described in US 5571286, the contents of which are incorporated herein by reference.

Methods for preparing the polymeric materials are described in US 5571286. Hence the polymeric material can be, for example, the reaction product of a diamine or triamine oo polyoxyalkylene polymer having a polymerisation degree of from 4 to 50 or a mixture thereof with epichlorohydrin in a ratio of epichlorohydrin to amino nitrogen of from 1:1 to 3:1.

The amino groups in the polymeric material of the invention may wholly or partly in the form of derivatives of amino groups. Derivatives include, for example, adducts formed by alkylation or hydroxyalkylation at the nitrogen atom or by the formation of an amide group at the nitrogen atom. The derivatives may be formed by the reaction of the amino groups with a bifunctional bridging agent or with a cross- linking agent.

Preferably, the polymeric material is obtainable by the reaction of a polymer of formula B(R),, wherein n is from 1 to 20, B is a backbone group to which each R is covalently bonded and R is a group comprising a poly(oxyalkylene) chain, which chain comprises an amino end group, the polymer being optionally reacted with a bridging compound, with a cross-linking agent. It will thus be appreciated that the polymeric material of the invention is a relatively complex mixture comprising a number of different compounds, some or all of which may be cross-linked.

The poly(oxyalkylene) chain which forms a part of the R group may be, for example, a poly(oxyethylene), poly (oxybutylene) or poly (oxyprop-1l,2-ylene) chain. The length of the chain can vary from 2 to 100 repeat units.

Conveniently,n is 2 or 3. It will be appreciated that n may : not be a whole number where the polymeric material of the invention comprises a mixture of different polymers of formula B(R),.

In some of the polymeric materials which may be used in the invention,B is -0-CH; (CH) p,—CH,-0O- (ie, B is the residue of glycerol when m is 1) and m is equal 0 to n-2.

However, B can also represent other values such as , for example, the residue of other triols or the residue of a di- , tetra-, penta- or hexa- hydroxy compound. Alternatively,

B can represent the residue of a di-, tri- or poly- amine.

Preferably, at least one R group has the formula - (CH2CH (R') (CH2) a0) p-A-NHR'', wherein: R' is H or CHs; a is 0, 1 or 2; p is an integer from 5 to 30; A is an alkylene group; and R'' is H or alkyl. More preferably, p is from 10 to 25.

The term “alkyl”, as used herein, includes C; to C¢ alkyl, optionally substituted on the alkyl chain, which may be branched or unbranched and, for C3; to Cg alkyl, may be cyclic. The term “alkylene” is defined similarly but refers to a divalent radical.

It will be appreciated that the term “end group” refers to the group at or near to the end of the poly(oxyalkylene) chain, which end, when the polymer is of formula B(R),, is at the other end of the polymer chain from the end which is attached to B.

Suitable polymers of formula B(R), include those having the following structure:

H,C-O (CH,CH(R') 0) p—A-NH;

HC-O (CH,CH(R'") 0) —A-NH;

H2,C=O (CH,CH(R')O0) ,~A-NH, wherein R' is as defined herein before, P, q and r are integers which may be the same or different and may be from 5 to 30 and A is branched or unbranched lower alkylene.

Other suitable polymers of formula B(R),, in which n is equal to 2, include those having the following formula:

HaN- (CHz) p= (O (CHz) 4) =O (CHz) cO- ( (CH2) 40) g2— (CH2) p~NH, wherein: b is an integer from 1 to 6, preferably 3; c is an integer from 1 to 6, preferably 4; and d and d2 are the same or different and are integers from 10 to 15.

The cross-linking agent which is used to form the polymeric material of the invention by reaction with the polymer, or the polymer after prior reaction with the bridging compound, preferably comprises an epihalohydrin. Epichlorohydrin is a suitable epihalohydrin.

Preferably the molar ratio of cross-linking agent to polymer of formula B(R), is from 0.5:1 to 4:1. Other amounts of cross-linking agent may be present in the polymeric material of the invention.

Suitable bridging compounds comprise two epoxide or carboxylic acid groups. The epoxide or carboxylic acid groups may be linked by a linker comprising alkylene, arylene, poly(oxyalkylene) or siloxane groups or combinations thereof. Examples of bridging compounds therefore include benzene-1,4-dicarboxylic acid, hexane-1, 6- dicarboxylic acid and poly (oxyethylene) compounds terminated at both ends of the molecule by an epoxide group. Other suitable bridging compounds are disclosed in US 5571286.

The composition of the invention can contain the polymeric material, optionally together with other polymeric materials. The compositions may further comprise a silicone

- 9g = which is capable of reacting with the polymeric material.

Suitable reactive silicones include those having amino or hydroxyl groups which are well-known to those skilled in the art.

Preferably, the polymeric material is capable of increasing the wet strength of paper by at least 200% compared to untreated paper when applied to paper having a weight of 80 g/m’ at a level of 1% solids by weight based on weight of paper, according to the test method described hereinafter. ] Polymeric materials which are suitable for use in the } present invention are available from Precision Processes

POLYMER AM

Polymer MRSM has the same structures as polymer AM but has silicone added to the polymer mixture.

The nature of the textile compatible carrier will be dictated to a large extent by the stage at which the composition of the invention is used in a laundering process, the compositions being capable of being used, in principle, at any stage of the process. For example, where the compositions are for use as main wash detergent compositions, the one or more textile compatible carriers comprise a detergent active compound. Where the compositions are for use in the rinsing step of a laundering process, the one or more textile compatible carriers may comprise a fabric softening and/or conditioning compound.

The compositions of the invention preferably comprise a perfume, such as of the type which is conventionally used in fabric care compositions. The compositions may be packaged and labelled for use in a domestic laundering process.

The polymeric material is preferably present in the product in a sufficient quantity to give an amount of 0.0005% to 5% by weight on the fabric based on the weight of the fabric, more preferably 0.001% to 2% by weight on fabric. The amount of the polymeric material in the composition required to achieve the above % by weight on fabric will typically be in the range 0.01% to 35% by weight, preferably 0.1 to 13.5% by weight.

The compositions of the invention, when applied to a fabric, can impart benefits to the fabric when uncured. However, they may be cured by a domestic curing step including ironing and/or domestic tumble drying, preferably tumble drying. The curing is preferably carried out at a temperature in the range of from 50 to 100°C, more preferably from 80 to 100°C.

In the context of the present invention the term “textile compatible carrier” is a component which can assist in the interaction of the first component with the fabric. The carrier can also provide benefits in addition to those provided by the first component e.g. softening, cleaning . etc. The carrier may be water, in which case the composition of the invention will contain another additive, . suitable for use in laundry compositions such as perfume, for example, or the carrier may be a detergent-active compound or a fabric softener or conditioning compound or other suitable detergent or fabric treatment agent.

If the composition of the invention is to be used in a laundry process as part of a conventional fabric treatment product, such as a detergent composition, the textile- compatible carrier will typically be a detergent-active compound. Whereas, if the fabric treatment product is a rinse conditioner, the textile-compatible carrier will be a fabric softening and/or conditioning compound.

If the composition of the invention is to be used before, or after, the laundry process it may be in the form of a spray or foaming product.
