  • Publication number: 20020193265
    Abstract: Novel cosmetic compositions comprising, in a cosmetically acceptable medium, (a) at least one anionic surfactant chosen from N-acylated compounds of mono- and polyamidated polycarboxylic amino acids and the salts of said acids and (b) at least one particular soluble conditioning agent. This combination can impart at least one cosmetic property (such as sleekness, lightness, softness) without keratinous fiber-regreasing phenomenon. These compositions are used, for example, for washing and/or conditioning keratinous materials such as the hair or the skin.

  • Publication number: 20020193274
    Abstract: The present invention relates to cationic sugar surfactants with improved biodegradability that can be used as hydrotropes for surfactants, especially for nonionic alkylene oxide adducts in alkaline solutions, and as cleaners for hard surfaces. The cationic sugar surfactants contain at least one hydrocarbon group with 6-24 carbon atoms and at least one quaternary ammonium group where at least one substituent is an alkyleneoxy containing group which is connected to a saccharide residue by a glycosidic bond. They are obtained from ethoxylated quaternary ammounium compounds and reducing saccharides or alkyl glycosides.
