AI Technical Summary

Problems solved by technology

As the content of emollient increases, the skin oiliness will also increase accordingly, so the use of emollients is limited
For example, petroleum jelly has long been used medicinally as a skin conditioner, but has only limited cosmetic use due to its extremely greasy feel and sticky properties

Abstract

The present invention relates to an O / W / O emulsion comprising; a) an external oil phase which comprises an emulsifying crosslinked siloxane elastomer and a solvent for the emulsifying crosslinked siloxane elastomer; and b) an O / W type primary emulsion which comprises an internal oil phase dispersed in an aqueous phase dispersed in the external oil phase wherein the aqueous phase comprises from about 0.01% to about 10% of a hydrophobically modified polymeric emulsifier, wherein when shear stress is applied to the O / W / O emulsion during spreading on skin, at least a portion of the primary emulsion is released from the O / W / O emulsion. The present invention also relates to an O / W / O emulsion composition comprising: a) from about 0.1% to about 15% of an emulsifying crosslinked siloxane elastomer; b) from about 0.01% to about 10% of a hydrophobically modified polymeric emulsifier; c) from about 1% to about 40% of a solvent for the emulsifying crosslinked siloxane elastomer; and d) water, wherein when shear stress is applied to the composition during spreading on skin, phase separation is occurred.

Description

field of invention [0001] The present invention relates to multiple emulsion skin care compositions. Such compositions are useful for delivering skin care actives in products having consumer acceptable aesthetics, in particular for moisturizing, protecting and / or treating the skin and / or keratinous fibers. Background of the invention [0002] Oil-in-water-in-oil (O / W / O) multiple emulsions have shown importance in various industries, including cosmetics, food products, and pharmaceuticals, among others. O / W / O emulsions, in which the oil-in-water emulsion is further emulsified in a continuous oil phase comprising two oil phases (i.e., an inner oil phase and an outer oil phase separated from each other by an aqueous phase), and can be used to formulate Two or more oil-soluble substances that may be incompatible with each other in an emulsion. Likewise, it can be used to deliver oil-soluble compounds that are susceptible to oxidation by incorporating them into an internal oil ...
