Preparation of oil-in-water emulsion, comprises heating a portion X1 of the total water quantity (phase X) and oil- or fat phase and optionally emulsifier/further oil- or fat-component (phase Y); subsequently mixing the portion X1 and phase Y; subsequently providing a portion X2 of the total water quantity; subsequently slow mixing and homogenizing the mixture; subsequently slow mixing of the remaining portion X3 of the water; subsequently homogenizing and providing polysaccharide and aroma material. Preparation of oil-in-water emulsion (that represent no microemulsion) containing (a) oil- or fat phases (0.5-15 wt.%) comprises oil component, which is at least 20[deg]C liquid, such as (i) 3-30C-alkanol with at least propylene-unit per molecule, (ii) propylene glycol monoester of branched saturated 6-30C-alkanecarboxylic acid and (iii) branched saturated 10-30C-alkanol; (b) at least water (60 wt.%), (c) at least cosmetic active substance (0.00001-38 wt.%), (d) at least polysaccharide, (e) optionally at least an nonionic emulsifier with an HLB-value of 3-6, (f) optionally at least an non-ionic emulsifier with HLB value of 12-18, (g) optionally at least aroma material in the oil- or fat phase, and (h) optionally oil- or fat component, comprises (1) heating a portion of X1 of the total water quantity (phase X) and (a) and optionally contains emulsifier/further oil- or fat-component (phase Y) separated from one another at 70-80[deg]C; (2) subsequently mixing the portion X1 of phase X with the phase Y at lower shear; (3) subsequently homogenizing; (4) subsequently stirring in low revolution; (5) subsequently cooling the reaction at 40-50[deg]C; (6) subsequently providing a portion X2 of the total water quantity containing a C1 portion of cosmetic active agent, that is temperature stable at 40-50[deg]C; (7) subsequently slow mixing of the portion (X2+C1) with the total reaction at 40-50[deg]C; (8) subsequently homogenizing; (9) subsequently slow mixing of the remaining portion X3 of the water, where the reaction has 30-40[deg]C; (10) subsequently homogenizing; (11) subsequently providing polysaccharide and aromatic material, that is temperature stable at 40-50[deg]C and further provides preservative and pH-regulator etc.; (12) subsequently homogenizing; and (13) subsequently cooling at 25[deg]C under slow stirring. Independent claims are included for: (1) a cosmetic, non-therapeutic use of oil-in-water emulsion, where (c) is sweat inhibiting active agent for the sweat inhibiting treatment of the skin, preferably shoulder skin and/or the foot skin; (2) oil-in-water emulsion obtained by the above procedure; and (3) a cosmetic, non-therapeutic procedure for sweat inhibiting treatment of the skin, preferably shoulder skin and/or the foot skin, comprising applying the oil-in-water emulsion. |
