First Claim
Patent Images
1. A method of producing a bigel, the method comprising:
- (a) providing an oleogel comprising at least one oily agent gelled with at least one cellulose polymer;
(b) providing an aqueous gel comprising at least one component whose viscosity is pH dependent;
(c) mixing the oleogel and the aqueous gel together to form a bigel; and
(d) subsequently adjusting the viscosity of the bigel under high flow and low shear mixing to obtain a bigel of a desired viscosity.

Abstract
A method for producing a bigel, the method comprising: (a) providing an oleogel comprising at least one oily agent gelled with at least one cellulose polymer; (b) providing an aqueous gel comprising at least one component whose viscosity is pH dependent, such as a carbomer; (c) mixing the oleogel and the aqueous gel together to form a bigel; and (d) subsequently adjusting the viscosity of the bigel under high flow and low shear stirring to obtain a bigel of a desired viscosity.
