PERFUMES IN THE FORM OF AQUEOUS MICROEMULSIONS
-
Paragraph 0136-0140, (2020/11/30)
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.
Process for preparing alcohol derivatives
-
Example 1, (2008/06/13)
The present invention provides a process for preparing an alcohol derivative, where the alcohol derivative is an ester, acetal, ketal, ether glycoside, or alkyl glycoside, by reacting an alcohol with a carbonyl compound, alcohol, olefin, epoxy compound or saccharide, where C2-4 vicinal alkylene oxides are excluded, in the presence of (A) an aluminum alkoxide and (B) sulfuric acid or phosphoric acid.
Process for producing glyceryl ether
-
, (2008/06/13)
A process for producing a glyceryl ether which contains a markedly small amount of organohalogen compounds and therefore can be used even for cosmetics and body detergents. The process comprises reacting an alcohol with an α-epihalohydrin in the presence of an acid catalyst, subjecting the reaction mixture to ring closure to convert it into the corresponding glycidyl ether and then hydrolyzing the glycidyl ether, wherein: (a) the hydrolysis is effected at 140 to 230° C. in the presence of a salt formed from a strongly basic compound and a weakly acidic compound, or (b) the reaction mixture after the hydrolysis is heated at 100 to 230° C. in the presence of a salt formed from a strongly basic compound and a weakly acidic compound.
