Abstract
Long term stable, oil-in-water emulsions that have a high concentration of plasticized MQ-type resin and/or its derivatives in an internal phase. Also, novel compositions for topical use that comprise our MQ resin emulsions. These compositions include, hair care products, especially for treating split ends, skin care products, such as sunscreens, and systems for delivering actives to skin and hair. In some preferred embodiments, the MQ emulsion is stabilized in such a way that the surface tension of the emulsion is sufficiently close to the surface tension of a target surface, such as damaged hair or skin.
Claims20
A composition comprising:
- a continuous aqueous phase, and
- a discontinuous phase that comprises plasticized MQ-type resin and/or derivatives thereof, and/or plasticized MT-type resin and/or derivatives thereof,
- wherein the discontinuous phase is emulsified in the aqueous phase.
A stable emulsion product comprising:
- a continuous aqueous phase;
- a discontinuous phase emulsified into the continuous phase, comprising:
- a subphase of trimethylsiloxysilicate resin and/or derivatives thereof, dimethicone silicone gum and volatile solvent, wherein the ratio of trimethylsiloxysilicate resin to dimethicone silicone gum in the subphase is about 15:1 to 1:15;
- and
- a surfactant system comprising:
- at stearic acid and sodium hydroxide;
- PEG-9 polydimethylsiloxyethyl dimethicone;
- and
- methyl glucose sesquistearate.
