Abstract: The invention relates to a composition comprising: a) one or more polyhydroxyalkanoate (PHA) copolymers which contain, and preferably consist of, at least two different repeating polymer units chosen from the units (A) and (B) below, and also the optical or geometrical isomers thereof and the solvates thereof such as hydrates: -[-0-CH(R1)-CH2-C(0)-]- unit (A) -[-0-CH(R2)-CH2-C(0)-]- unit (B) in which polymer units (A) and (B): R1 represents a hydrocarbon-based chain chosen from: i) branched (C5-C9)alkyl, ii) (C10-C30)alkyl; iii) linear or branched (C5-C30)alkenyl; iv) linear or branched (C5-C30)alkynyl; v) (hetero)aryl; vi) (hetero)cycloalkyl; preferably the group i) (C10-C20)alkyl, or iii) (C8-C20)alkenyl; R2 represents a cyclic or non-cyclic, linear or branched, saturated or unsaturated hydrocarbon-based group, comprising from 1 to 30 carbon atoms; and b) a fatty medium comprising one or more fatty substances; preferably, the fatty substance(s) are liquid at 25°C and at atmospheric pressure; it being understood that (A) is different from (B).

Abstract: The present invention relates to polyhydroxyalkanoate (PHA) copolymers bearing acetoacetate group(s) and derivative(s), to a composition comprising same, and also to a process for treating keratin materials using such PHAs, notably for making up the skin or for colouring or styling keratin fibres, preferably the hair.
Thus the main subject of the present invention is a) a polyhydroxyalkanoate (PHA) copolymer which contains, several units (A) below, and also the optical or geometrical isomers thereof, the organic or mineral acid or base salts thereof, and the solvates thereof such as hydrates: —[—O—CH(R1)—CH2—C(O)—]—  unit (A) in which polymer units (A): R1 represents a saturated or unsaturated, linear or branched, non-cyclic hydrocarbon-based chain, or a saturated or unsaturated non-aromatic cyclic hydrocarbon-based chain, comprising from 3 to 30 carbon atoms, said hydrocarbon-based chain being substituted with one or more groups chosen from: A) R3′—C(X)—C(R4)(R5)—C(X′)—[Y]n—* and B) R3′—C(X)—C(—[Y]n—*)(R4)—C(X)—R6 with R3′, R4, R5 and R6 as defined in the description.
