1. A method for reducing a tacky effect of an oil-in-water emulsion for topical use (E0) comprising, for 100% of said E0 a weight:
from 10% to 25% by weight of glycerol,
from 90% to 70% by weight, of a cosmetically acceptable aqueous phase (A0);
from 10% to 30% by weight of a fatty phase (G0), said fatty phase (G0) comprising, for 100% of said G0 a weight, from 2% to 8% by weight of at least one oil-in-water surfactant and from 88% to 99% by weight, of at least one oil and/or one wax,
wherein said emulsion (E0) does not comprise any synthetic polymers comprising silicone or any third compound of silicone nature,
wherein an effective amount of a mixture (M1) of cyclic or acyclic, linear or branched saturated hydrocarbons, among which at least 95% by weight comprise from fifteen to nineteen carbon atoms, is incorporated into said oil-in-water type emulsion for topical use (E0),
wherein said effective amount of a mixture (M1) is from 5% to 20% by weight of said oil-in-water emulsion, and the weight ratio between the glycerol and said mixture (M1) is less than or equal to 5 and greater than or equal to 2, and wherein said mixture (M1) comprises, for 100% of its weight either:
branched alkanes of greater than or equal to 80% by weight and less than or equal to 100% by weight, linear alkanes of greater than or equal to 0% by weight and less than or equal to 15% by weight, and cycloalkanes of greater than or equal to 0% by weight and less than or equal to 5%, by weight and up to 5% by weight of said cyclic, acyclic, linear or branched hydrocarbons comprise less than fifteen carbon atoms or more than nineteen carbon atoms; or
branched alkanes of greater than or equal to 40% by weight and less than or equal to 100% by weight, linear alkanes of greater than or equal to 0% by weight and less than or equal to 20% by weight and cycloalkanes of greater than or equal to 0% by weight and less than or equal to 40% by weight, and 100% by weight of said cyclic or acyclic, linear or branched hydrocarbons comprise from fifteen to nineteen carbon atoms.
