Emulsified MQ resin: compositions and methods

摘要

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.

1. A stable emulsion product comprising:
a continuous aqueous phase; a discontinuous phase emulsified into the continuous phase, comprising:
a subphase of trimethylsiloxysilicate resin that has been plasticized with 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; anda surfactant system comprising: stearic acid and sodium hydroxide; lauryl PEG-9 polydimethylsiloxyethyl dimethicone and optionally PEG-10 dimethicone; and methyl glucose sesquistearate;wherein the discontinuous phase of the stable emulsion product is characterized by droplets of plasticized trimethylsiloxysilicate resin surrounded by a layer of lauryl PEG-9 polydimethylsiloxyethyl dimethicone, which is further surrounded by a layer of methyl glucose sesquistearate.
