Silicone modified polyolefins in personal care applications
The present invention provides personal care formulations containing silicone modified polyolefins and having improved sensory feel, as well as being non-tacky and easily spreadable. The present invention also provides a method for treating body surfaces such as skin, hair, nails, etc., by applying the aforesaid personal care formulations externally to such a surface. The present invention also provides a method for improving the sensory feel of personal care formulations by including one or more silicone modified polyolefins in the formulations.
1. A personal care formulation consisting of:
(A) a silicone modified polyolefin which is the reaction product of:
(i) at least one functionalized polyolefin comprising polymerized units derived from one or more olefin monomers selected from C 2 -C 40 olefins and having one or more functional groups selected from the group consisting of anhydrides and vinyl silanes of Formula A:
wherein R 1 is a hydrogen atom or methyl group; x and y are 0 or 1, with the proviso that when x is 1, y is 1; m and n are independently an integer from 1 to 12 inclusive; and each R″ is, independently, a hydrolyzable organic group selected from the group consisting of an alkoxy group having from 1 to 12 carbon atoms, an aryloxy group, an araloxy group, an aliphatic acyloxy group having from 1 to 12 carbon atoms, an amino group, a substituted amino group, and a lower alkyl group having 1 to 6 carbon atoms inclusive, with the proviso that not more than one of the R″ groups is an alkyl; and
(ii) at least one functionalized silicone polymer comprising polymerized units derived from one or more siloxanes selected from the group consisting of silanol terminated polydimethylsiloxane, mono-aminopropyl terminated polydimethylsiloxane, bis-aminopropyl terminated polydimethylsiloxane, vinyl terminated polydimethylsiloxane, mono-aminopropyl grafted polydimethylsiloxane, bis-aminopropyl grafted polydimethylsiloxane, or vinyl grafted polydimethylsiloxane;
(B) a carrier; and
(C) at least one other ingredient selected from the group consisting of emollients, waxes, sensory modifiers, rheology modifiers, humectants, sunscreen actives, bioactives, colorants, particles, emulsifiers, solubilizers, and combinations thereof.
2. The personal care formulation of claim 1 , wherein said carrier is selected from the group consisting of: aromatic or aliphatic hydrocarbons, alcohols, aldehydes, ketones, amines, esters, ethers, glycols, glycol ethers, silicone oils, water, and combinations thereof.
3. A method for treating the body which comprises applying the personal care formulation of claim 1 externally to the body.
