Abstract
The invention relates to a blend, and a process for its use, which is made up of specific castor polyesters and anionic surfactants, which when used to clean the hair provide detergency and cleaning attributes, but surprisingly also provide the hair with gloss.
Claims34
A composition used to clean and provide gloss to the hair, which comprises a blend of;
- (1) anionic surfactants selected from the group consisting of
- (a) sulfates conforming to the following structure:
- wherein;
- R1 is alkyl having from 8 to 18 carbon atoms,
- M is selected from the group consisting of Na, K, NH4
- (b) ether sulfates, which conform to the following structure:
- wherein
- R2 is alkyl having from 8 to 18 carbon atoms,
- M is selected from the group consisting of Na, K, NH4,
- f is an integer ranging from 1-10,
- and
- (c) alpha olefin sulfonate which conform to the following structure:
- wherein
- R3 is alkyl having from 8 to 18 carbon atoms,
- M is selected from the group consisting of Na, K, NH4,
- and
- (2) a polymeric castor polyester which conforms to the following structure;
- A—(B)x—A
- wherein;
- the linking group between all of the O— are succinyl groups conforming to the following structure —C(O)—CH2—CH2—C(O)—;
- R is selected from alkyl and alkylene having 5 to 33 carbon atoms;
- x is an integer ranging from 1 to 50.
