Abstract (en)
[origin: FR2784310A1] The emulsion consists of oil phase, in form of globules dispersed in aqueous phase. Oil phase constitutes at least 15 wt.% per total wt. of emulsion. Aqueous phase contains at least one copolymer (C) composed of main fraction of 3-6C carboxylic acid monomer with mono-olefin unsaturation, or its anhydride, and minor fraction of acrylic acid fatty chain ester monomer; and contains no surfactant. The emulsion consists of oil phase, in form of globules of average size below 20 (preferably 0.5-15) microns dispersed in aqueous phase. Oil phase constitutes at least 15 wt.% per total wt. of emulsion. Aqueous phase contains at least one copolymer (C) composed of main fraction (80-98 wt.%) of 3-6C carboxylic acid monomer with mono-olefin unsaturation, or its anhydride, and minor fraction (2-20 wt.%, per total wt. of two monomers) of acrylic acid fatty chain ester monomer; and contains no surfactant. Independent claims are also included for: (1) The use of emulsion as claimed in treatment, protection, care and/or cleaning of skin, mucous membranes and/or hair, and/or for make-up of skin and mucous membranes, and also in production of dermatological compositions for treatment and/or protection of skin, mucous membranes and/or hair; and (2) process of making the emulsion as claimed, comprising introducing oil phase under pressure higher than critical pressure (preferably 30-350 kPa) into aqueous phase containing copolymer, through porous glass membrane having average pore size 0.1-5 (preferably 0.3-3) microns.
