Description

Compositions for tissue care.

Technical field

The present invention relates to compositions for tissue care and tissue treatment methods using the compositions

Background and prior art

The washing procedure generally has several advantages for tissues, the most common being eliminating dirt and stains of the fabric during the wash cycle and soften the tissue during the rinse cycle.

However, there are numerous associated disadvantages with repeated use of conventional treatment compositions of laundry and / or the actual washing procedure; being one of these a fairly severe treatment of the tissue in the process of washed.

The tissues can be damaged in various ways as a result of repeated washing and / or use. Tissue stripping and loss of appearance of the tissue surface, for example lint formation, shrinkage (or expansion), loss of color of tissue or tissue color shift (normally called dye transfer) are some of the problems Common associated with repeated washing. These problems can occur merely by repeated hand washing as well as by Vigorous machine wash procedure. In addition, they are also significant problems related to tissue damage over time by normal use, such as loss of form and Increase in the likelihood of wrinkling.

The present invention is directed towards alleviating one or more of these problems.

The main advantage of the present invention is refers to improving the definition of surface color of a tissue after multiple washes and / or provide resistance to peeling and / or lint formation of the tissue during washing. The invention It may have additional advantages in tissue treatment. By For example, other aspects of the overall appearance can be improved of the tissue, such as a reduction in the tendency of the tissue to fold and / or wrinkle.

WO98 / 29530 describes washing detergent compositions containing agents polyamide-polyamine tissue treatment. The compositions are claimed to impart a global appearance enhanced to washed fabrics using detergent compositions, in terms of surface appearance properties such as peeling / lint reduction and anti-fading. In WO97 / 42287, teach detergent compositions containing agents polyamide-polyamine type treatment Similar.

Washing compositions containing agents polyamide-polyamine tissue treatment may exhibit increased dye collection (i.e. increase in dye transfer) and poor removal properties of  stains compared to other wash compositions conventional.

Certain amphoteric polymers of polyurethane that are useful as lubricating agents in the industrial tissue treatment. An example of such a composition of Polymers is the product sold under the trademark Arristan PD from CHT, Germany. Methods for preparing amphoteric polymers of these types are known and are described, for example, in the US 3997490.

It is well known that wool products are prone to shrinkage and various treatments are known industrials that can reduce the trend of products from wool to shrink. These procedures are often intended to apply to all clothing instead of finished garments. By several reasons many of these procedures are not suitable for, or are intended for domestic use, being restricted in its application to the unique treatment of products or tissues.

GB 1547958 (IWS Nominee Company) explains how wool can become resistant to shrinkage by an oxidative treatment such as chlorination. Saying chemical procedure reduces the washing capacity, so that IWS proposes the treatment of ketaratin fibers with polymer amphoteric crosslinks. GB 159272 (IWS Nominee Company) further describes suitable polymers. Each of the procedures described in these patents are essentially a unique industrial process, where the polymer needs to be emptying of the solution on the wool substrate and such emptying requires the use of emptying agents or acidic pH. These methods of emptying of the treatment agent on the tissue are not suitable for the domestic washing procedure and in general the procedure is not suitable for repeated use on products finished

Definition of the invention

The present invention is based on the surprising discovery that certain amphoteric polymers they can impart improved surface appearance on fabrics of cellulose. Polymers can have the additional advantage of reducing  adverse side effects, in terms of dye transfer increased and poor stain removal, for example, compared with certain compositions containing treatment agents of polyamide-polyamine fabrics. Conveniently, the polymers can be applied repeatedly in an operation of normal household washing without the need for emptying agents or acidic pHs.

In accordance with the present invention, provides a fabric care composition comprising one or more fundamental carriers and compatible with materials textiles and an amphoteric polymer that is capable of self-crosslink and / or react with the cellulose.

The invention also provides a method of tissue treatment, as part of a washing procedure, which comprises applying to the fabric an amphoteric polymer that is capable of self-crosslinking and / or reacting with the cellulose, in a fundamental carrier and compatible with materials textiles

In addition, the invention provides the use of a amphoteric polymer that is capable of self-crosslinking and / or react with cellulose to improve the definition of color of a fabric after multiple washes.

In another aspect, the invention provides the use of an amphoteric polymer that is capable of self-crosslink and / or react with cellulose to impart resistance to peeling and / or lint formation of fabric during washing.

In yet another aspect, the invention provides the one of an amphoteric polymer, which is capable of self-crosslink and / or react with cellulose to increase the degree of tissue staining release stained. In addition, the invention may impart other properties. beneficial to the fabric, such as folding and / or reduced creasing of tissue during washing.

Detailed description of the invention

The invention is based on tissue treatment with an amphoteric polymer that is capable of self-crosslink and / or react with cellulose in the presence of a suitable carrier. The carrier is both compatible with textile materials as fundamental of the material textile.

In the context of the present invention the expression "carrier compatible with textile materials" is a component that can assist in polymer interaction amphoteric with tissue. The carrier can also provide advantages in addition to those provided by the amphoteric polymer, by example softness, cleanliness, etc. The carrier can be, by example, a detergent active compound or a softening compound or conditioner or other detergent or tissue treatment agent suitable.

If the composition of the invention is to be used in a washing process as part of a conventional product of tissue treatment, such as a detergent composition, the carrier compatible with textile materials will typically be a detergent active compound. Meanwhile, what if the product of Tissue treatment is a rinse conditioner, the carrier compatible with textile materials will be a softening compound and / or tissue conditioner.

The compositions of the invention can be used at any stage of the washing procedure. Preferably, the compositions are used to treat the tissue in the cycle of rinsing of a washing procedure. The rinse cycle continues preferably to the treatment of the tissue with a composition Detergent.

If the composition of the invention is to be used before, or after the washing procedure, it may be in It forms a powdered or foam product.

The carriers that have a positive charge, including fabric softeners and / or conditioning agents are particularly preferred since these carriers promote the deposition of the polymer on the surface of the tissue.

The most preferred embodiments of the invention are those in which the composition comprises a fabric softener fabrics or a conditioning composition comprising itself a group of quaternary nitrogen. It is believed that these materials they can function as a carrier forming a complex with the amphoteric polymer

Tissues that can be treated include those comprising cellulose fibers, preferably from 1% to 100% cellulose fibers (more preferably 5% to 100% fibers of cellulose, most preferably 40% to 100%). Tissue can be in the form of a garment, in which case the method of The invention may represent a method of washing a garment. When the tissue contains less than 100% cellulose fibers, the balance comprises other fibers or mixtures of suitable fibers for use of garments such as, for example, polyester. Preferably, the cellulose fibers are cotton or cellulose regenerated such as viscose.

The washing procedures of the present invention include large-scale and small-scale cleaning (by domestic example) of tissues. Preferably, the procedures They are domestic.

Polymers

The polymer is amphoteric and therefore It comprises both anionic and cationic groups.

The amphoteric polymer preferably comprises a number of cationic and anionic groups such that the charge total provided by the cationic and anionic groups is zero or substantially zero. However, the expression "amphoteric" as used herein also covers cases in which the polymer comprises both cationic and anionic groups but a slight molar excess (for example, a 10% molar excess) of one of these groups on the other cause that the polymer is Slightly charged positively or negatively.

The cationic groups are preferably obtained by reaction of an epihalogenohydrin (such as epichlorohydrin) with amino groups in or on the main polymer structure. The amino groups may, for example, be secondary amino groups. that are present in the polyamine that is part of the main polymer structure. Cationic groups can be azetidine groups of the following type:

one

In some embodiments, the polymer comprises two or more isocyanate end groups.

The polymer used in the invention is capable of self-crosslinking and / or reacting with cellulose. This ability to self-crosslink and / or react with cellulose may be due to isocyanate groups in the polymer. Additionally or alternatively, the ability to self-crosslinking and / or being reactive with cellulose it may be due to the presence of other reactive groups in the polymer, including cationic and anionic groups in the polymer.

Preferably, the polymer has a main polymer structure comprising at least one chain polyurethane-urea-polyamine or polyurethane-urea-polyamide. He polymer can take any suitable form, including linear, branched or star shape (but most preferably the polymer is linear). The polymer may have different chains that the chains polyurethane-urea-polyamide or polyurethane-urea-polyamine, being these other chains linked at the end of or within the polyurethane-urea-polyamide chains or polyurethane-urea-polyamine.

The anionic groups in the polymer are preferably bound to a nitrogen atom in the structure Main polymer by an alkylene chain. Alkylene chain it can be of formula (CRR ') n, in which R and R' are the same or different and are hydrogens or lower alkyls (including C1 to C3 unbranched or C3 branched alkyl) and n is an integer from 2 to 20, preferably 2 to 10, plus preferably 2 to 5 (such as 3). R and R 'can be the same or different such as different carbon atoms along the alkylene chain Therefore, the formula (CRR ') n covers, by example, not just groups such as (CH2) (CH2) (CH2) but also groups such as (CH2) (CH (CH3)) (CH2). The anionic group is preferably monovalent. Suitable anionic groups include SO 3 {-} and CO 2 {-}.

The polymer preferably contains bonds urethane and / or amide and / or amine that are repeated at least twice in the polymer chain Polyoxyalkylene polymers can form a part of the main polymer structure, preferably bound to the polymer by urethane bonds at its ends by For example, by reacting a polyoxyalkylene polymer with a di- o poly isocyanate. Similarly, polymers of polyamine can form a part of the main structure of the polymer, preferably bonded to the polymer via bonds urea at its ends for example, by reaction of the polyamine with a di- or polyisocyanate.

The polymer can be produced by methods known. For example, the polymer can be formed according to the procedure established in document US 3997490, the contents of which are incorporated herein as reference. Therefore, the polymer can be obtained by reacting an isocyanate terminated urethane prepolymer, formed to starting from a polyhydroxy compound (such as a polymer polyoxyalkylene) and an excess of polyisocyanate (such as a diisocyanate), with an excess of a polyamine to form a polyurethane-urea-polyamine. The polyurethane-urea-polyamine as well formed reacts then to enter the groups charged (eg ionic) in the polymer. The polyurethane-urea-polyamine can reacted with an epihalogenohydrin (such as epichlorohydrin) to introduce cationic groups into the polymer. Polyurethane-urea-polyamine can reacted to introduce anionic groups into the polymer (before or after the introduction of cationic groups, preferably after the introduction of the groups cationic), for example by reaction of the polyurethane-urea-polyamine (containing optionally cationic groups) with 1,3-propanesulfone, 1,4-butanesulfone, β-propiolactone, ε-caprolactone, δ-valerolactone or a monohalogenocarboxylate of sodium of formula X (CH2) pCOONa, in which X is halogen and p is an integer from 1 to 5. Alternative or additionally, anionic groups can be introduced into the polymer by reaction of the polyurethane-urea-polyamine (which optionally contains cationic groups) with acrylonitrile or a acrylate or methacrylate ester and then hydrolyzing the product to convert ester groups to groups carboxylate.

The isocyanate groups that are preferably Polymer contents are capable of reacting with water, although the speed of this hydrolysis reaction can be slow. Accordingly, the compositions of the invention are preferably substantially anhydrous (for example, being in solid form or liquids containing non-aqueous solvents) or They contain water in a relatively minor amount.

Any isocyanate groups in the polymer are they can protect (for example, by reaction with bisulfite), with in order to reduce its susceptibility to hydrolysis. These groups Protected isocyanates fall within the meaning of the expression "isocyanate groups", as used herein.

The compositions of the invention have the surprising advantage of imparting resistance to tissue use, and therefore cause an improved surface color definition of tissue after washing, particularly after multiple washed In addition, the polymeric materials contained in the compositions need not cause unacceptable problems of dye transfer and / or stain removal.

Polymers suitable for use in the invention are available in the form of polymer compositions sold under the trademark ARRISTAN PMD of CHT, Germany.
