Abstract
Abstract Products for the personal care industry are formulated with gels comprising a telomer-copolymer of ethylene and a silane, and a solvent. Preferably a silicone oil or a substitute is included with sufficient solvent to provide a stable ternary gel. The gels provide the inherent advantages of silicones in such applications while reducing the amount required and improving stability of the formulations.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
172 words
A ternary gel for use in personal care products consisting essentially of: (a) a telomer-copolymer of ethylene and a silane having the formula: ##STR3## where: x is 0 or 1 y is 0 or 1 R 1 is H or an aliphatic radical having 1-5 carbon atoms R 2 is a saturated aliphatic radical having 1-10 carbon atoms or an aryl radical having no more than two aromatic rings m is 1-5 n is 1-5 v is 1-3 R 3 is H or an aliphatic radical having 1-4 carbon atoms said copolymer having a number average weight of from 500 to 10,000 and containing from 0.1 to 70% by weight of the silane; (b) at least one member of the group consisting of silicone oils, castor oil, and propylene glycol; and, (c) a suitable solvent in sufficient amount to provide a compatible and stable gel where said solvent is at least one member of the group consisting of fatty alcohols, fatty esters, poly butene, hydrocarbon oils, animal-derived oils, and vegetable derived oils.
