Emulsifiers having w/o-stabilizing properties and their use
WIPO Patent Application WO/2015/161378
Publication date: Oct. 29, 2015
Assignee: Intelactive S.A. and A. Thibodeau
Described in this patent application are emulsifiers that can stabilize w/o emulsions. The emulsifiers are homogenous and have a relatively low melting point; e.g., are soft paste, gels or liquids at room temperature. This enables their use in cold-process methods and formulations.
In general, the emulsifiers comprise: a) polyglycerol fatty acid esters consisting of saturated and unsaturated fatty acid esters of polyglycerol; b) polyhydroxystearic acid copolymers consisting of copolymers of hydroxystearic acid with saturated and unsaturated fatty acids; and c) hydroxystearic acid. Methods and uses relating to the emulsifiers are also described, for example in cosmetic and pharmaceutical compositions.
According to the inventors, the advantages of the emulsifiers stem from synergistic interactions between their principal components.
