Fabric and home care composition

A fabric and home care composition comprising:

• (i) graft polymer;
• and
• (ii) one or more fabric and home care ingredients,
• wherein the graft polymer consists of:
• (A) 20 to 95% of a polymer backbone as a graft base,
• which comprises at least one sub-unit (a1) and at least one sub-unit (a2), wherein
• (a1) is a unit comprising, preferably essentially consisting of, moieties derived from at least one alkylene oxide monomer and/or at least one polyalkylene oxide-polymer having two hydroxy-end-groups, the alkylene oxide monomer selected from the group of C2 to C10-alkylene oxides,
• (a2) is a unit comprising at least one lactone and/or at least one hydroxy acid, such sub-unit (a2) being a moiety derived from a single lactone and/or hydroxy-acid or being oligo-or-polymeric units consisting of at least one type of lactone and/or at least one type of hydroxy acid,
• wherein the at least one lactone and/or hydroxy acid is/are selected from the groups i) and/or ii), with
• i) lactone(s), i.e. cyclic esters, starting with α-lactone (three ring atoms) followed by β-lactone (four ring atoms), γ-lactone (five ring atoms) and so on;
• such lactones preferably being β-propiolactone, g-butyrolactone, δ-valerolactone, g-valerolactone, e-caprolactone, d-decalactone, g-decalactone, e-decalactone;
• preferably caprolactone;
• and
• ii) hydroxy acid(s), which may be derived from any lactone by hydrolyzation, specifically from any lactone within group i) before, specifically an α-, β- or γ-hydroxy acid derived from the corresponding lactone by hydrolyzation, and lactic acid, glycolic acid, 4-hydroxybutanoic acid, 6-hydroxy hexanoic acid, 12-hydroxy stearic acid, citric acid;
• wherein the polymer backbone is obtained:
• (A1) by co-polymerization of at least one sub-unit (a1) and at least one sub-unit (a2), wherein optionally at least one oligomer or polymer made from at least one sub-unit (a1) or at least one sub-unit (a2) can be employed within the copolymerization of at least one sub-unit (a1) and at least one sub-unit (a2) as well;
• (A2) by first oligo-/polymerizing sub-unit(s) (a2) and then polymerizing the product with sub-unit(s) (a1);
• or
• (A3) by first oligo-/polymerizing sub-unit(s) (a1) and then co-polymerizing the product with sub-unit(s) (a2);
• (A4) by first providing an oligo- or polymeric sub-unit (a1) which is bears an end-cap on one side, is etherified with short-chain alcohols C1 to C4, which—as starter-block—is thereafter reacted with at least one sub-unit (a2) and/or at least one sub-unit (a1)—wherein the sub-unit (a1) may be different to that/those in the starter block or may be arranged in a different order compared to those in the starter block—to attach to the non-endcapped side of the starter block a new block comprising moieties from the sub-units employed for the (co-)polymerization, thereby obtaining a di-block-structure of [end-cap]-[sub-unit(s) (a1)]-[sub-unit(s) (a2)], or [end-cap]-[sub-unit(s) (a1)]-[random-{sub-unit(s) (a2)-sub unit(s) (a1)}];
• wherein in case more than one sub-unit (a1) and/or more than one sub-unit (a2) are present already in an employed oligomer or polymer, those sub-units can be arranged in any order within such employed oligomer or polymer, and
• wherein in case more than one sub-unit (a1) and/or more than one sub-unit (a2) are present for the polymerization, those sub-units (and the optional oligomer/polymers if employed) can be arranged in any order within the obtained backbone;
• and
• (B) 5 to 80% of polymeric sidechains (B) grafted onto the polymer backbone (A), wherein said polymeric sidechains (B) are obtainable by (co-)polymerization of at least one vinyl ester monomer (B1), optionally vinylpyrrolidone as monomer (B2), and optionally further monomer(s) (B3), and optionally further monomers,
• with all percentages as weight percent in relation to the total weight of the graft polymer.
