  • Perfumes in the form of aqueous microemulsions
    Patent number: 11052025
    Abstract: Disclosed is a microemulsion of oil-in-water type including, preferably consisting of, by weight relative to the total weight of microemulsion: •70% to 94% of water, •1% to 15% of at least one hydrophobic fragrancing substance, •4% to 20% of at least one preferably volatile solvo-surfactant, and •0.1% to 15%, preferably 1% to 13%, of at least one hydrotropic agent or at least one surfactant selected from anionic surfactants, cationic surfactants, amphoteric surfactants and non-ionic surfactants. The solvo-surfactant is selected from monoalkylated glycerol derivatives of following formula (I): wherein the “alkyl” group is a linear or branched alkyl group including from 1 to 8 carbon atoms, and R and R? are each independently H or a linear or branched alkyl group including from 1 to 5 carbon atoms, with the proviso that R is different from R?, and mixtures thereof.
