Abstract
The invention relates generally to gels or viscous fluids formed by the coordination of certain amino-functionalized siloxanes with titanates and the use of the same in cosmetic compositions, including for providing long-wearing, comfortable films on a keratinous surface (e.g., lips). The gels or viscous fluids may exhibit unique rheological properties, including shear thickening (dilatancy) and/or rheopecty, at low shear rates which may lead to self-leveling effects, including renewable shine; and may exhibit high gloss and low shear.
Claims42
A gel or viscous fluid formed from about 3-15% by weight of a titanium alkoxide, about 5-25% by weight of a functionalized amodimethicone polymer selected from hydroxyl-functionalized amodimethicone polymers or alkoxy-functionalized amodimethicone polymers capable of hydrolysis to hydroxyl-functionalized amodimethicone polymers, and about 50-95% by weight of an oil which gels with said titanium alkoxide and hydroxyl-functionalized amodimethicone polymer;
- wherein a film of said gel or viscous fluid is characterized by a gloss value above about 55 gloss units, and a tack value below about 200 g.

A cosmetic composition comprising a gel or viscous fluid formed from about 3-15% by weight of isopropyl triisostearyl titanate, about 5-25% by weight of a hydroxyl-functionalized amodimethicone polymer, about 50-95% by weight of an oil which gels with said isopropyl triisostearyl titanate and hydroxyl-functionalized amodimethicone polymer, and from 0 to about 10% by weight end-capped amine-functionalized siloxane polymer;
- wherein the hydroxyl-functionalized amodimethicone polymer has the structure:
- wherein R6 and R7 are independently groups-(CH2)k—, where k is an integer from 1-6;
- and where “x,” “y” are integers from 1-500, selected such that the polymer has a functional group equivalent weight (FGEW) of amine of about 12-19 milli-equivalents per gram and a viscosity between about 500 and about 2,500 cps at 25° C.;
- wherein the end-capped amine-functionalized siloxane polymer of the form:
- where “n” is an integer from 1-300, selected such that the polymer has a viscosity between about 10 cps and about 2,500 cps at 25° C.;
- and
- wherein a film of said composition is characterized by a gloss value above about 55 gloss units, and a tack value below about 200 g.
