Abstract:
PCT No. PCT/GB94/02014 Sec. 371 Date Apr. 8, 1996 Sec. 102(e) Date Apr. 8, 1996 PCT Filed Sep. 15, 1994 PCT Pub. No. WO95/07613 PCT Pub. Date Mar. 23, 1995An oil in water emulsion comprises a continuous aqueous phase and a discontinuous oil phase which is either a hydrophobic liquid which is immiscible with the aqueous phase or is a solid phase obtained by providing an emulsion in the aqueous phase of a solution of potentially solid material in the hydrophobic liquid and converting this solution to a solid phase, and the emulsion is stabilized by the inclusion of water-soluble stabilizing polymer in the aqueous phase and oil solubilizing stabilizing material, generally polymer, in the oil phase. The or each polymer is preferably a copolymer of hydrophilic and hydrophobic groups, preferably being formed by copolymerization of water-soluble monomer and oil-soluble monomer that provide the desired groups in the polymer without further reaction. Partially hydrolyzed polyvinyl alcohol can be used as the water-soluble polymer.
