Abstract: A personal care composition is provided which includes a trihydroxy and quaternary ammonium substituted dipropyl ether. The substituted dipropyl ether functions as a humectant when applied to human skin to moisturize both in high and low relative humidity environments.

Abstract: New 4-substituted resorcinol derivatives of general formula I and/or B and process for synthesizing same, cosmetic compositions and methods of using same, particularly for skin lightening: Wherein X1 and/or X2 represents hydrogen (H), linear or branched, saturated or unsaturated C1-C12 alkyl, alkenyl, or acyl groups. Preferably, X1 and/or X2 represents hydrogen (H); linear or branched, saturated or unsaturated C1-C12 alkyl or acyl groups; R1 represents hydrogen (H), linear or branched, cyclic or acyclic, saturated or unsaturated C1-C12 alkyl, alkenyl, cycloalkyl, or cycloalkenyl group. Preferably, R1 represents hydrogen (H) or a C1 alkyl group (i.e, methyl group). More preferably, R1 represents hydrogen; n represents 0, 1. When n=0, the ring is a cyclopentyl with or without one heteroatom from O, N or S and/or with or without one double bond.

Abstract: The invention relates to an improved process for oxidizing a primary amidoalcohol to the corresponding amidocarboxylic acid in high yield.

Abstract: Process for carboxy-alkylation, particularly carboxymethylation, of branched alcohols includes the reaction of isoalcohols with potassium-t-butoxide or sodium-t-butoxide and with salt of halogenated alkanoic acid in the presence of the isoalcohol (starting alcohol) as the solvent. Produced are isoalcohol carboxy-alkylates (preferably, carboxymethylates) in excellent yields and purity.
