Abstract: Cosmetic oil-in-water emulsion comprises: e.g. (a1) Acacia decurrensand jojoba and sunflower seed wax and polyglyceryl-3-ester, (a2) cetearyl alcohol, (a3) propylheptyl caprylate, (a4) pentaerythritol distearate, (a5) Limnanthes albaseed oil, (a6) Butyrospermum parkii, (a7) bis-polyethylene glycol/polypropylene glycol-20/5-polyethylene glycol/polypropylene glycol-20/5 dimethicone, (a8) isoamyl laurate, (b1)water, (b2) sodium hyaluronate, (b3) glycerol, (b4) EDTA, (b5) hydrogenated lecithin, alcohols and palmitic acid. Cosmetic oil-in-water emulsion comprises (in wt.%, based on the total wt. of the emulsion): (a1) Acacia decurrensand jojoba and sunflower seed wax and polyglyceryl-3-ester (1.5-2.5), (a2) cetearyl alcohol (1-2), (a3) propylheptyl caprylate (2.5-3.5), (a4) pentaerythritol distearate (1.5-2.5), (a5) Limnanthes albaseed oil (1-1.5), (a6) Butyrospermum parkii(shea butter) (0.5-1.5), (a7) bis-polyethylene glycol/polypropylene glycol-20/5-polyethylene glycol/polypropylene glycol-20/5 dimethicone (1.5-2), (a8) isoamyl laurate (3-4), (b1)water (sufficient quantity to 100), (b2) sodium hyaluronate (0.9-1.1), (b3) glycerol (3-4), (b4) EDTA (0.09-0.11), (b5) hydrogenated lecithin, alcohols with 12-16 carbon atoms and palmitic acid (1.5-2.5), (b6) silica, CI (color index) 77891 (titanium dioxide) and CI 77491 iron oxide (2-3), (b7) silica, CI 77891 (titanium dioxide) and tin oxide (0.5-1), (b8) xanthan gum (1-1.5), (b9) ethylene/acrylic acid copolymer (3-4), (b10) polydodecanamideaminium triazadiphenylethenesulfonate and polyvinylalcohol crosspolymer (2-3), (c1) alcohol (ethanol) (5-6), (c2) preservative (0.7-0.8), (c3) Sinorhizobium melilotiferment filtrate, cetyl hydroxycellulose, lecithin, postassium sorbate, sodium benzoate, tocopherol and trisodium EDTA (2-3), (c4) Camellia sinensisleaf extract, propylene glycol and water (0.5-1), (c5) ergothioneine, phenoxyethanol and water (0.1-0.2), (c6) dimethicone (4.5-6), (c7) chamomile extract (0.3-1), (c8) extract of the salt of the micro-algae Dunaliella salina(0.2-0.5), (c9) plankton extract and lecithin (0.1-0.2), (c10) liposomes with wheat extract (0.1-0.5), (c11) liposomes with acerola extract (0.3-0.5), (c12) liposomes with barley extract (2-4), (c13) liposomes with retinol (2-3), and (c14) perfume oil (0.1-0.3). The preparation of the cosmetic oil-in-water emulsion comprises stirring (a) a fat phase, (b) a water phase and (c) an alcohol phase independently, where the fat phase comprises the components (a1)-(a8), which are mixed together at 15-30[deg] C, water phase comprises the components (b1)-(b9), which are mixed together at 15-30[deg] C, stirred to 500 revolutions/minute and heated to 70[deg] C, at which the component (b10) is added and the phase is homogenized for 1-5 minutes at 3000 revolutions/minute, and alcohol phase comprises the components (c1)-(c14), which are mixed together at 15-30[deg] C, adding alcohol phase to the mixture of the fat- and water phase under stirring, after cooling to 40-45[deg] C, and then homogenizing the whole mixture at 3000 revolutions/minute for maximum of 3 minutes, until a viscosity of 100000-150000 mPa.s is attained. Independent claims are also included for: (1) producing the cosmetic oil-in-water emulsion by the above mentioned method; and (2) use of the emulsion as a body care product.
