Abstract:
1. A high internal phase water-in-oil emulsion, HIPE, consisting essentially of: (a) water; (b) emulsifier having an HLB of less than 9; (c) from about 0.1 to about 25% by weight steric stabilizer, the steric stabilizer being polyethylene glycol or polyglycerine cross-linked elastomer having a chain length from about 8 to about 26 carbon atoms; (d) from about 0.25 to about 20% by weight depletion stabilizer, the depletion stabilizer being an alkyl modified cross-linked elastomer having a polyethylene glycol or polyglycerine crosslinking group with a chain length from about 8 to about 26 carbon atoms; and (e) oil comprising D wherein the HIPE thickens when being topically applied in the presence of water and is capable to carry and deliver an active while showering or bathing and further wherein the emulsion is substantially free of non-emulsifying elastomer and comprises a water droplet size that is from about 10 to about 15 times smaller than about 40 to about 50 microns during topical application.
