Process according to the preceding claim, characterized in that the fatty substances are chosen from C6-C16 hydrocarbons, hydrocarbons containing more than 16 carbon atoms, triglycerides, fatty alcohols, esters of fatty acids and/or of fatty alcohols other than triglycerides, and silicones, or mixtures thereof, preferably from mineral oils, liquid fatty alcohols, liquid esters of fatty acids and/or of fatty alcohols, and silicone oils, or mixtures thereof, and better still from mineral oils, liquid fatty alcohols, and liquid esters of fatty acids and/or of fatty alcohols, or mixtures thereof.

Process according to either of the preceding claims, characterized in that the composition comprises a fatty ester, which is preferably liquid, and at least one non-silicone oil.

Process according to any one of the preceding claims, characterized in that the fatty substance(s) are liquid at room temperature and at atmospheric pressure.

Process according to any one of the preceding claims, characterized in that, when the propellant(s) are present in the composition, the fatty substance(s) is or are present in an amount ranging from 0.1% to 80% by weight, better still from 2% to 60% by weight, even more preferentially from 5% to 30%, relative to the total weight of the composition.

Process according to any one of the preceding claims, characterized in that the composition comprises one or more C2-C4 monoalcohols, the C2-C4 monoalcohol preferably being ethanol.
