Abstract: Use of (a) at least one 1,2-alkanediol with 5-8 carbon atoms and/or (b) at least one compound comprising an ammonium-, sodium- or potassium-R(alk)-sarcosinate as a solubilizer for at least one organic substances, for increasing solubility of at least one organic substance, and for reducing the turbidity and increasing the transparency of a preparation, preferably a dispersion and/or an emulsion comprising at least one organic substance, where the structural element R(alk) is 12-22C alkanoyl, 12-22C alkenoyl or 12-22C alkadienoyl, sodium- and/or potassium 10-16C alkyl sulfoacetate, is claimed. Use of (a) at least one 5-8C 1,2-alkanediol and/or, (b) at least one compound comprising an ammonium-, sodium- or potassium-R(alk)-sarcosinate as a solubilizer for at least one organic substances, for increasing solubility of at least one organic substance, and for reducing the turbidity and increasing the transparency of a preparation, preferably a dispersion and/or an emulsion comprising at least one organic substance, where the structural element R(alk) is 12-22C alkanoyl, 12-22C alkenoyl or 12-22C alkadienoyl, sodium- and/or potassium 10-16C alkyl sulfoacetate and, and the organic substances respectively exhibit a log K(OW) value of 1-12, preferably 3-8, is claimed. Independent claims are also included for: (i) a mixture comprising (i) at least one 5-8C 1,2-alkanediol, (ii) at least one ammonium-, sodium- or potassium-R(alk)-sarcosinate, where the structural element R(alk) is 12-22C, preferably 16-22C alkanoyl, 12-22C, preferably 16-22C alkenoyl or 12-22C, preferably 16-22C alkadienoyl, and (iii) optionally at least one sodium- or potassium-10-16C-alkyl sulfoacetate, where the mixture is not a cream for lips comprising water (60.05 wt.%), methylparaben (0.2 wt.%), Span 65(RTM: Sorbitan tristearate) (1 wt.%), cetyl alcohol (4.7 wt.%), Glycerol mono/di/tri stearopalmitate (3.9 wt.%), Myrj 52P(RTM: Polyethylene glycol stearate with 40 ethylene oxide units (2.22 wt.%) Amphysol K(RTM: Potassium hexadecyl phosphate) (0.83 wt.%), isoparaffin oil (4.7 wt.%), diisostearyl malate (7 wt.%), polydimethylsiloxanes with a viscosity of 5cst (5 wt.%), propylparaben (0.1 wt.%), decanediol und polyethylene glycol-ether (10 wt.%), perfume (0.3 wt.%), glycerin (7.50 wt.%), 1,2 pentanediol (3.00 wt.%), sodium palmitoyl sarcosinate (0.50 wt.%), pigments (3.24 wt.%), sodium saccharinate (0.02 wt.%), water (5 wt.%) and steareth-1 00/polyethylene glycol-1 36/hexamethylene diisocyanate copolymer (0.50 wt.%); (ii)a composition for preparing a cosmetic preparation, preferably a personal care agent comprising the mixture and at least one substances with a log K(OW) value of 1-12, preferably 3-8; and (iii) a cosmetic preparation comprising the mixture and at least one organic substances with log K(OW) value of 1-12, preferably 3-8 or the composition and optionally additional cosmetically active ingredients, and optionally additional components; and #increasing the solubility of the organic substance, reducing the turbidity of the preparation containing the organic substance and/or increasing the transparency of the preparation containing at least one organic substance with log K(OW) of 1-12, preferably 3-8, comprising mixing the organic substance with the mixture.
