Definitions
- the present invention relates to the use of certain polyether polyesters as dye transfer-inhibiting active ingredients in the washing of textiles and to detergents that contain such compounds.
- detergents In addition to the constituents essential for the washing process such as surfactants and builders, detergents generally contain further ingredients which may be grouped together under the heading of washing auxiliaries and thus include various groups of active ingredients such as foam regulators, graying inhibitors, bleaching agents, bleaching activators and enzymes.
- auxiliary substances also include substances which are intended to prevent dyed textiles from having a modified colour appearance after washing. This change in colour appearance of washed, i.e. clean, textiles may be due, on the one hand, to proportions of the dye being removed from the textile by the washing process ("fading"), and, on the other hand, to dyes dissolved out from differently coloured textiles being deposited onto the textile (“discolouration").
- detergents especially when they are intended as "colour" detergents for washing coloured textiles, contain active ingredients which are intended to prevent the dissolution of dyes from the textile or at least the deposition of dissolved-out dyes present in the washing liquor onto textiles.
- active ingredients which are intended to prevent the dissolution of dyes from the textile or at least the deposition of dissolved-out dyes present in the washing liquor onto textiles.
- Many of the polymers conventionally used have such a high affinity for dyes that they draw them to a greater extent from the dyed fiber, resulting in greater colour losses from the washed textiles.
- Polycondensation products of 20 - 50 mole % dicarboxylic acid, 10.1 mole % polyol with at least 3 OH-groups, 10.1 - 50 mole % alkylene oxide addition product of C 1-6 -alcohol and0.1 - 30 mole % diol are known from the international patent application WO 02/18474 A1 .
- Such oligoesters are said to be useful in laundry detergents, hair treatment compositions ans hard surface cleaning compositions, by improving the cleaning performance of such compositions.
- the present invention accordingly, provides the use of polyether polyesters obtainable by reacting, preferably by polycondensation, of
- the preventive action against the staining of white or also differently coloured textiles by dyes washed out of the textiles is particularly pronounced when the textile is made of or comprises cotton; nevertheless, there is also an effect on synthetic fibres like polyester, polyacrylate, elastane, polyamide and mixtures thereof, especially seen at increasing concentrations of the polymers mentioned above. It is conceivable that the polyether polyesters attach themselves to the textiles during washing and have a repellent action on the dye molecules present in the liquor.
- Preferred polyether polyesters are made by polycondensation, of
- polyether polyesters can be synthesized by esterification or transesterification.
- a dicarboxyl compound (A) aliphatic and/ or aromatic dicarboxylic acids or their esters can be used.
- the dicarboxylic acid compounds preferably have 3 to 40 carbon atom, with reference to the dicarboxylic or dicarboxylic group.
- Aromatic dicarboxylic compounds, according to the present invention can be terephthalic acid, isophthlalic acid, phthalic acid, its mono- and diesters with C 1 - to Cs-alcohol, such as, for example, dimethylterephthalate, whereby also mixtures of these components are possible.

- suberic acid azelaic acid
- sebacic acid and their alkyl esters.
- terephthalic acid, isophthalic acid and phthalic acid, as well as their dimethyl-, diethyl-, dipropyl- and dibutylesters are used.
- the polyol compound (B) preferably has 3 to 12 carbon atoms.
- the polyol compound (B) with at least 3 OH-groups the following are proposed: pentanerythritol, trimethylolethane, trimethylolpropane, 1,2,3-hexanetriol, sorbite, mannite, mono-, di- and triglycerol, 1,2,3-butanetriol.
- the use of glycerol is preferred.
- alkylene oxide addition products are addition products of ethylene oxide, propylene oxide, butylene oxide or their mixtures to aliphatic C1 to C6-alcohol, such as methanol, ethanol, propanol or butanol.
- Preferred are addition products of ethylene oxide to methanol.
- diol compound (D) As the diol compound (D), according to the present invention, ethylene glycol, 1,2- or 1,3 propylene glycol, neopentylglycol, as well as their dimers, trimers, can preferably be used.
- the diol compound (D) preferably has has 2 to 20 carbon atoms. Essentially, also mixtures of different diols are possible. Preferred is the use of ethylene glycol and/or propylene glycol.
- polyether polyester may take place in the form of direct reaction of all monomer components in one step, so that statistic polymers are produced.
- a different mode of manufacture is a multi-step synthesis, for example of the type that a tire condensation of different components takes place.
- temperatures of approximately 80 to 350° C and pressures of normal pressure to smaller than 1 bar are used.
- the condensation is performed in the temperature range of 150 to 280° C in the presence of common polycondensation- and esterification catalysts.

- the common transesterification catalysts may be used, such as, for example, zinc acetate, mixtures of calcium acetate and antimony oxide, stannates or tetra alkoxy-titanates, such as titantetra-isobutanolate, or tetra-isopropa nolate.
- the condensation can be performed in the presence of anti-oxidants, for example, substituted phenols, such as for example, 2,5 di-tertiary butylphenol, 2-methylcyclohexyl-4,6-dimethylphenol, phosphoric acid or other antioxidants commonly used for this purpose. These compounds prevent oxidative coloration of the polyether polyester during condensation.
- anti-oxidants for example, substituted phenols, such as for example, 2,5 di-tertiary butylphenol, 2-methylcyclohexyl-4,6-dimethylphenol, phosphoric acid or other antioxidants commonly used for this purpose.

- a more preferred mode of performing the present invention is by employing a detergent that additionally contains an enzyme, as defined below.
- the polyether polyesters make a contribution to both of the above-mentioned aspects of colour consistency, that is they reduce both discolouration and fading, although the staining prevention effect, in particular when washing white textiles, is most pronounced.
- the present invention accordingly also provides the use of the polyether polyesters defined above for avoiding the modification of the colour appearance of textiles when they are washed in aqueous solutions, in particular surfactant-containing aqueous solutions.
- a modification of the colour appearance should not be taken to mean the difference between the dirty and the clean textile, but instead the difference between the clean textile in each case before and after the washing operation.

- the detergents may contain one surfactant or two or more surfactants, it being possible in particular to consider not only anionic surfactants, nonionic surfactants and mixtures thereof, but also cationic, zwitterionic and amphoteric surfactants.
- Suitable nonionic surfactants are in particular alkylglycosides and ethoxylation and/or propoxylation products of alkylglycosides or linear or branched alcohols in each case having 12 to 18 C atoms in the alkyl moiety and 3 to 20, preferably 4 to 10, alkyl ether groups.

- nonionic surfactants which are known to be low-foaming, such as for example C 12 -C 13 -alkyl polyethylene glycol/polybutylene glycol ethers with in each case up to 8 mol ethylene oxide and butylene oxide units per molecule and end group-terminated alkylpolyalkylene glycol mixed ethers.
- Alkoxylated alcohols containing hydroxyl groups, or "hydroxy mixed ethers" are also particularly preferred.
- Alkylglycosides of the general formula RO(G) x in which R means a primary linear or methyl-branched aliphatic residue, in particular methyl-branched in position 2, with 8 to 22, preferably 12 to 18 C atoms, and G denotes a glycose unit with 5 or 6 C atoms, preferably glucose, may also be used as nonionic surfactants.
