A bactericidal or bacteriostatic composition comprising an acetal or a hexitan ether preferentially of a long-chain alkyl sorbitan, arlitan or mannitan, its use in the treatment or prevention of Gram-positive bacterial infections, its use as a hygiene or dermatological product for external use and a method for disinfecting surfaces.

Antibacterial composition comprising an acetal or a long-chain alkyl hexitane ether

The invention relates to an antimicrobial composition of monoanhydro-hexitol monoalkyl ether isomers bearing an alkyl ether radical (OR) at C-3, C-5 or C-6 of the monoanhydro-hexitol, in which the alkyl group (R) is a linear or branched, cyclic or noncyclic hydrocarbon-based group comprising between 4 to 18 carbon atoms. The invention also relates to a method for disinfecting a surface and/or equipment contaminated by bacteria, said method comprising applying to said surface or equipment to be disinfected, a composition according to the invention.

Antibacterial compositions of mono-alkyl ethers of monoanhydro-hexitols and antibacterial methods using of the same

A bactericidal or bacteriostatic composition comprising an isomer mixture of monosaccharide alkyl monoethers or monoacetals, its use in the treatment or prevention of Gram-positive bacterial infections, its use as a hygiene or dermatological product for external use and a method for disinfecting surfaces.

Antibacterial composition containing an isomer mixture of monosaccharide alkyl monoacetals or monoethers

A process for obtaining a mixture of C4-C8 and C9-C18 alkyl monoether of saccharide, comprising: a) a first step of acetalization or trans-acetalization of a saccharide or of a mixture of saccharides with a C4-C8 aliphatic aldehyde or the acetal thereof, b) a second consecutive or simultaneous step of acetalization or trans-acetalization of the product obtained in a) of the saccharide or mixture of saccharides with a C9-C18 aliphatic aldehyde or the acetal thereof, c) a step of catalytic hydrogenolysis of the saccharide acetals obtained, and d) a step of recovery of a mixture of C4-C8 and C9-C18 alkyl saccharide monoethers. The invention further relates to a mixture of C4-C8 and C9-C18 alkyl saccharide monoethers and the use thereof as a surfactant.

Synthesis of monoethers of sugar comprising a long alkyl chain and uses thereof as a surfactant

A composition of monoanhydro-hexitol monoalkyl ether isomers bearing an alkyl ether radical (OR) at C-3, C-5 or C-6 of the monoanhydro-hexitol, in which the alkyl group (R) is a linear or branched, cyclic or noncyclic hydrocarbon-based group comprising between 4 to 18 carbon atoms, the process for obtaining such a composition and the use thereof as a nonionic surfactant, emulsifier, lubricant, antimicrobial agent or dispersant.

Compositions of mono-alkyl ethers of monoanhydro-hexitols, production methods thereof and use of same

Long-chain alkyl cyclic acetals made from sugars are obtainable by a method that comprises the steps consisting of:
