  • Patent number: 11806413
    Abstract: The application relates to an emulsifying composition, in particular for cosmetic use, allowing an oil-in-water emulsion (O/W) to be obtained, the emulsion comprising at least one cyclodextrin and at least one O/W emulsifier of natural origin with a hydrophilic-lipophilic balance value (HLB) of more than 8. The O/W emulsifier of natural origin can be selected from alkyl polyglucosides, mixtures of at least one alkyl polyglucoside and at least one fatty alcohol, and non-ethoxylated polyol fatty esters. The application also relates to a composition of the Pickering emulsion type, in particular for cosmetic use, containing the emulsifying composition according to the invention, and to the process for preparing such a composition of the O/W Pickering emulsion type, in particular at low temperatures.

  • Patent number: 11690795
    Abstract: Thickening system consisting of: a) at least one pregelatinized starch, b) at least one gum of plant or microbial origin, c) and at least one cellulose derivative. Process for manufacturing a stable thickened system, by means of the steps of: a) providing an aqueous solution, b) heating the water to a temperature of between 20° C. and 80° C., preferentially between 20° C. and 50° C., c) introducing into the aqueous solution at least one pregelatinized starch, at least one nonionic polysaccharide and at least one anionic polysaccharide, d) stirring the medium until dispersion of the constituents in the water is obtained.
