Shea butter dimethyl amidopropyl amines
View Patent ↗Novel dimethyl amidopropyl amines prepared by the reaction of dimethyl amidopropyl amine (DMAPA) and shea butter, preferably mild-processed shea butter (MPSB). Materials of the present invention are useful as cosmetic and personal care ingredients, allowing for the delivery of highly desirable active ingredients present in shea butter including natural antioxidants, in a cationic material that is substantive to the skin and hair.
1. A shea butter dimethyl aminopropyl amine conforming to the structure:
wherein
R is derived from shea butter and comprises
from about 0.1 to about 2.0% by weight C 11 H 23 ;
from about 0.5 to about 2.0% by weight C 13 H 27 ;
from about 2.0 to about 6.0% by weight C 15 H 31 ;
from about 25 to about 50% by weight C 17 H 35 ; and
from about 40.0 to about 60.0% by weight C 17 H 33 .
2. A DMAPA derivative of claim 1 made by the amidation reaction of dimethyl amidopropyl amine and mild-processed shea butter.
3. A DMAPA derivative of claim 2 wherein the amidation is conducted at a temperature of from about 180° C. to about 190° C.
4. A process for treating hair and skin with an effective concentration of a dimethyl amidopropyl amine made by the amidation reaction of dimethyl amidopropyl amine and shea butter.
5. A process for treating hair and skin of claim 4 wherein the amidation is conducted at a temperature of from about 180° C. to about 190° C.
6. A shea butter dimethyl aminopropyl amine of claim 1 where the shea butter is mild-processed.
7. A process of claim 4 where the shea butter is mild-processed.
