Methods of making the leuco polymer, laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.

A method of obtaining a leuco polymer, the method comprising the step of reacting a compound with a polymer to form the leuco polymer. The compound includes at least one leuco moiety and at least one electrophilic group. The polymer is comprised of co-monomers of an aryl dicarboxylate, an oxyalkyleneoxy and an oxypolyalkyleneoxy and the polymer comprises at least one moiety selected from the group consisting of hydroxy, sulfhydryl, primary amine and secondary amine. Laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.

A leuco composition comprises at least one reactive leuco compound, which reactive leuco compound comprises a leuco moiety and at least one reactive moiety covalently bound to the leuco moiety. A laundry care composition comprises a laundry care ingredient and a leuco composition. A method of treating a textile comprises the steps of (i) treating a textile with an aqueous solution containing a leuco composition, (ii) optionally, rinsing the textile, and (iii) drying the textile.

A leuco polymer includes a leuco monomer and an alkene. The leuco polymer has a molecular weight of at least 500 and is obtainable by polymerization of the leuco monomer and one or more alkene co-monomers. The leuco monomer consists of an alkene covalently bound to a leuco moiety and the leuco monomer has a molar extinction coefficient at a wavelength in the range 400 to 750nm of less than 1000 M.sup.1cm.sup.1. The alkene monomer(s) have a molar extinction coefficient at a wavelength in the range 400 to 750nm that is less than 100 M.sup.1cm.sup.1. Methods of making the leuco polymer, laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.

A process is shown that relates to a process for providing at least one solid fraction from a textile product including a natural fibre and/or a synthetic fibre, wherein the process includes the steps of: i) proving the coloured textile product including a natural fibre and/or one or more synthetic fibres; ii) adding a liquid solution of dihydrolevoglucosenone and/or derivatives of dihydrolevoglucosenone in water, thereby providing a decolorized textile product; and iii) separating the decolorized textile product from the liquid fraction, thereby providing the at least one solid fraction.
