Abstract
Abstract Mixture of compounds of general formula: <IMAGE> (I) in which R denotes a saturated C10-C12 hydrocarbon radical, or mixture of such radicals, and n has a mean statistical value from 2 to 15, and preferably from 3 to 12. These products are very well tolerated by the skin and the mucosa, and are advantageously used in cosmetic or pharmaceutical compositions.
