Some embodiments relate to a novel process for preparing compositions including alkyl(alkyl-glucoside)uronates, from biobased or biocompatible/biodegradable raw materials, and also salts and acids thereof.

Process for preparing compositions comprising alkyl(alkyl-glucoside)uronates, said compositions and use thereof as a surfactant

The invention relates to a composition (C) including: (a) at least one compound of formula (I) in which each of the radicals Z is a hydrogen atom or a monovalent radical (Z); (b) at least one compound of formula (IV); (c) a compound of formula (V). The invention also relates to a method for preparing said composition and to the use thereof in cosmetics. 

Composition of alkyl polyglucosides and fatty esters of cationic amino acids

The invention relates to a surfactant composition including at least one compound of formula (I): in which each of the radicals Z is a hydrogen atom or (Z); at least one compound of formula (IV); one compound of formula (V); and one compound of formula (VI). The invention also relates to a method for preparing said composition and to the use thereof in cosmetics. 

Emulsifying composition with cationic nature

Multifunctional green and antimicrobial compositions are described containing cationic glycine betaine esters and/or cationic glycine betaine amides. Particular glycine betaine esters and amides are alkyl(ene) betainate methane sulfonates and betainyl amino alkyl(ene) methane sulfonates. The glycine betaine components are cationic, have a hydrophobic group attached to a carboxylate group through an ester or amide linkage, and are derived from a natural source, such as sugar beets. The glycine betaine esters and amides serve as cationic surfactants which have effective antimicrobial activity. The surfactant compositions are effective as crude mixtures or semi-purified mixtures or purified surfactant compounds of glycine betaine components. The addition of sodium chloride or potassium chloride or magnesium chloride or natural gum or polysaccharide to compositions containing the cationic glycine betaine ester and/or glycine betaine amide derivatives serves to thicken or gel the composition.

Green glycine betaine derivative compounds and compositions containing same

The invention relates to C-glycose compounds of formula (I) where: S' is a monosaccharide radical or a polysaccharide radical derived from a monosaccharide or polysaccharide S; R is a linear or branched alkyl radical; and Z is an ethylenyl CH&#x2550;CR1(R2) or an acetylenyl C&#x2261;CR3 radical. The invention also relates to a method for preparing C-glycoside compounds of formula (III), characterized in that the method consists of a step of reacting a sugar (S), in an aqueous solvent or in the absence of a solvent and in the presence of an organic or mineral base (B), with a phosphonate of formula (II) according to the following reaction pattern: Formulas (II), (III). 

C-glycoside compounds, and method for preparing C-glycoside compounds

Analogue compounds of archaebacterial membrane lipids and liposomal compounds integrating such compounds

The invention relates to surfactant compositions made from esters or amides of the betaine glycine, produced by reaction of the glycine betaine with a sulphonic acid and an alcohol or a fatty-chain amine derived from vegetable oils. The invention further relates to a cosmetic comprising said surfactant composition, in particular, liquid soap, bath foam, shower gel or shampoo.

Surfactant composition method for production thereof and cosmetic comprising said composition

The invention relates to an aqueous bitumen emulsion, comprising bitumen and a surfactant agent, made from esters or amides of glycine betaine, produced by reaction of glycine betaine with a sulphonic acid and an alcohol or amine with a fatty chain derived from vegetable oils. Said bitumen emulsion may be used in the production of road surfaces.
