β-amino ester compounds and uses thereof
View Patent ↗Hair treatment compositions are disclosed comprising a β-amino ester compound in a cosmetically acceptable vehicle, such as a spray or cream. In embodiments, the compounds include a polybutadiene moiety. Methods of treating hair with the compositions to impart volume, texture and definition are also disclosed.
1. A compound prepared by reacting a diacrylate or dimethacrylate of formula
with an amine of formula
H 2 N—R 2 ,
wherein R 1 is hydrogen or methyl;
R 2 is selected from the group consisting of alkyl, alkenyl, alkynyl, acyl, alkoxy, alkoxyalkyl, amino, aminoalkyl, aryl, heteroaryl, amido, alkylthioether, carbamoyl, carbonyldioxyl, carboxyl ester, cyclic aliphatic, cyclic heteroaliphatic, aromatic, heteroaromatic and ureido groups, each of which groups may be substituted with at least one substituent selected from the group consisting of alkyl, alkenyl, alkynyl, acyl, alkoxy, alkoxylalkyl, amino, aminoalkyl, aryl, heteroaryl, amido, cyclic aliphatic, heterocyclic aliphatic, halogen, hydroxyl, cyano, carbamoyl, carboxylic acid, carbonyldioxyl, alkylthioether, siloxyl, and thiohydroxyl groups; and
A is a rubber moiety with a molecular weight in a range of about 1000 g/mol to about 10,000 g/mol selected from the group consisting of butadiene, chloroprene, isoprene, and styrene-butadiene units.
2. The compound of claim 1 , wherein the diacrylate or dimethacrylate and the amine are reacted in a molar ratio of about 1:2 to about 2:1.
3. A hair treatment composition comprising a compound according to claim 1 in a cosmetically acceptable carrier.
4. The hair treatment composition of claim 3 , wherein the hair treatment composition is a hair styling product, shampoo, or conditioner.
5. The hair treatment composition of claim 4 , wherein the hair styling product is a spray, cream, gel, mousse, or pomade.
