Abstract: The present invention relates to a photoprotective composition comprising, in a physiologically acceptable medium, at least one photoprotective compound and a surfactant comprising at least one ester derivative or amide derivative of glycine betaine. It also relates to the cosmetic use of this photoprotective composition for protecting the skin against certain effects of UVA radiation, and also to this photoprotective composition for use thereof in the protection of the skin against erythema caused by UVB radiation. Finally, it relates to the use of the abovementioned surfactant for increasing the sand resistance of a photoprotective composition.

Abstract: The invention relates to a surfactant composition containing at least one ester or amide salt of glycine betaine, or a dermatological composition containing it, for use as a pediculicidal agent by topical application on the hair and the scalp. It also relates to a method for preventing and/or treating infestations of head lice and/or nits, comprising the application to a fabric surface of a topical composition containing a surfactant composition as defined above.

Abstract: The present invention relates to a method for conditioning keratin fibres, comprising topically applying, to the keratin fibres, a cosmetic composition in the form of an emulsion containing, in a cosmetically acceptable medium, a surfactant composition containing at least one ester or amide salt of glycine betaine comprising from 14 to 24 carbon atoms. The invention also relates to the use of a surfactant composition as defined above as an agent for conditioning the keratin fibres.

Abstract: The present invention relates to a process for preparing a surfactant composition based on glycine betaine ester salt, and to the composition thus obtained. The invention also relates to the uses of said composition. A subject of the invention is also a product comprising the abovementioned composition.

Abstract: The present invention relates to a surfactant composition based on glycine betaine amide salt and also to the process for preparing the same. The invention also relates to the use thereof as a wetting agent, particle dispersant and/or corrosion inhibitor and/or for improving the disinfectant power and/or the persistence of the disinfectant effect of antimicrobial substances and/or the insecticide effect and/or the persistence of insecticidal substances, and also in the manufacture of various products intended for treating and/or cleansing the body, plants or hard surfaces, for water treatment or for oil extraction. The invention also relates to a product comprising the abovementioned composition.

Abstract: 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.
