Abstract
Water-soluble or water-dispersible matrix, made of a polysaccharide modified under an electron beam with an organosilicon compound chosen from organosilanes and/or polyorganosiloxanes having at least one functional group capable of reacting and/or interacting with said polysaccharide. Use of the matrix as stabilizing agent in the preparation of simple emulsions, in particular of the water-in-oil type, or multiple emulsions, in particular of the water-in-oil-in-water type.
Claims44
A method of producing a water-soluble or water-dispersible matrix comprising the step of irradiating under an electron beam a mixture of:
- (i) at least one polysaccharide (PSA) and (ii) at least one organosilane (S) or polyorganosiloxane (POS) having at least one functional group capable of reacting and/or interacting with said polysaccharide (PSA).
A method for stabilizing a simple or multiple emulsion during the preparation thereof, said method comprising:
- (a) producing a water-soluble or water-dispersible matrix comprising the step of irradiating under an electron beam a mixture of (i) at least one polysaccharide (PSA) and (ii) at least one organosilane (S) or polyorganosiloxane (POS) having at least one functional group capable of reacting and/or interacting with said polysaccharide (PSA);
- (b) dissolving and/or dispersing the water-soluble or water-dispersible matrix produced in step (a);
- and
- (c) combining the aqueous solution or dispersion with the other phase or phases.
