The disclosure discusses polyol-glycoside compositions for topical use. The invention provides compositions containing an efficient amount of polyol-glycoside obtained from the acetalization of a polyol with a reducing sugar. Applications for the composition include cosmetics, pharmaceuticals, and textile treatments. 

Polyol-glycoside compositions for the skin

A self-reversible reverse microlatex composition comprising an oil phase, an aqueous phase, a water-in-oil surfactant(s), a oil-in-water surfactant(s) and 15% to 40% by weight by weight of a branched or crosslinked polyelectrolyte. The polyelectrolyte is based on a monomer containing a strong or weak acid function, which is partially or totally salified, a copolymer of at least one monomer containing a strong acid function and at least one monomer containing a weak acid function or at least one neutral monomer, a copolymer of at least one monomer containing a weak acid function and at least one neutral monomer, or a copolymer of at least one monomer containing a strong acid function, a monomer containing at least one weak acid function and at least one neutral monomer. The surfactants have a total HLB number of 8.5 to 11. Uses in cosmetics and as an industrial emulsifier and/or thickener.

Self-reversible reverse microlatex process for preparing it and cosmetic and industrial uses thereof

The ocular tolerance of cosmetic, dermocosmetic and dermopharmaceutical compositions is improved by the incorporation therein of an effective amount of a polyol-glycoside or of a mixture of polyol-glycosides of formula (I): R&#x2014;O-(G)-H (I) in which: &#x2014;x represents a decimal number between 1 and 5 and G represents the residue of a reducing sugar, and Rrepresents a radical of formula (A) &#x2014;CH&#x2014;(CHOH)&#x2014;CH&#x2014;OH (A) in which n is an integer equal to 2, 3 or 4, or else Rrepresents a radical of formula (B) &#x2014;(CH&#x2014;CHOH&#x2014;CH&#x2014;O)&#x2014;H (B) in which m is an integer equal to 1, 2 or 3. The invention also relates to new concentrates which contain compounds of formula (I), foaming and/or detergent surfactants and topically acceptable solvents, and also to processes for preparing them.

Method of improving the ocular tolerance of foaming and/or detergent compositions for skin use

A composition and process of preparation of emulsifier agents based on an alkylpolyglycoside structure with a length of alkyl chain having from 6 to 12 carbon atoms to be used. The resulting emulsions exhibit an excellent dispersion of the fillers and/or pigments without it being necessary to add coemulsifier or dispersant. The emulsifier makes it possible, by itself alone, to prevent the reagglomeration of the fillers and/or pigments.
