Multiple emulsion compositions |
摘要 |
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. |
