Abstract

A cosmetic composition is provided that includes an elastomer and at least one cosmetic component optionally in a cosmetically acceptable medium. The elastomer is according to the general formula: A-B-A or B-A-B, wherein each A independently comprises a polysiloxane moiety having at least two siloxy (Si—O) groups and wherein each B independently comprises a moiety, or a precursor thereof, having at least two carboxyl groups and wherein B is bonded to a silicon atom in A.

First claim

1 . A cosmetic composition comprising:
(a) an elastomer according to the general formula: A-B-A or B-A-B,
wherein each A independently comprises a polysiloxane moiety having at least two siloxy (Si—O) groups;
wherein each B independently comprises a moiety, or a precursor thereof, having at least two carboxyl groups; and
wherein B is bonded to a silicon atom in A; and
(b) at least one cosmetic component; (c) optionally in a cosmetically acceptable medium.

2 . A cosmetic composition comprising:
(a) an elastomer having at least two siloxy (Si—O) groups and at least two carboxyl groups, the elastomer comprising the reaction product of a reaction of:
a first component having at least one reactive group;
a second component having at least one reactive group; and
a third component having at least two reactive groups reactive with the reactive groups of the first and second component for linking the first component to the second component;
(b) at least one cosmetic component; and (c) optionally in a cosmetically acceptable medium.

3 . The cosmetic composition according to claim 2 , wherein the at least one reactive component of the first component and the second component are independently selected from a hydroxyl group or an amine group and wherein the at least two reactive groups of the third component are anhydride groups.

4 . The cosmetic composition according to claim 3 wherein the first and second component are selected from siloxanes having at least one hydroxyl group or organic alcohols having at least one hydroxyl group and the third component a siloxane having at least two terminal anhydride groups, or the first and second component are selected from siloxanes having at least one amine group or organic amines having at least one amine group and the third component a siloxane having at least two pendant anhydride groups.

5 . (canceled)

6 . The cosmetic composition according to claim 2 , wherein the at least one reactive component of the first component and the second component are anhydride groups and wherein the at least two reactive groups of the third component are hydroxyl groups or amine groups.

7 . The cosmetic composition according to claim 6 wherein the first and second component are siloxanes and the anhydride groups are pendant.

8 . The cosmetic composition according to claim 6 wherein the third component is selected from
i) an organic polyol having at least two hydroxyl groups;
ii) a third siloxane having at least two hydroxyl groups;
iii) an organic polyamine having at least two amine groups; or
iv) a third siloxane having at least two amine groups.
