Abstract:
Mono, di and tri-esters of 1,8-dihydroxy-10-phenyl-9-anthrone or -9-anthranol have the formula ##STR1## wherein p is 0 or 1,(a) when p=0, t=1 and R.sub.2 represents hydrogen or --COR.sub.3,(b) when p=1, t=0 and R.sub.1 and R.sub.2 each independently represent hydrogen or --COR.sub.3,R.sub.3 represents linear or branched alkyl having 1-17 carbon atoms, cycloalkyl, phenyl or phenyl substituted by lower alkyl, lower alkoxy, halogen, a nitro function, --CF.sub.3 or a hydroxyl function, and mixtures of said esters. These esters are prepared by reacting 1,8-dihydroxy-10-phenyl-9-anthrone with an activated form of an acid. The esters are useful in human or veterinary medicine and in cosmetic compositions.
Abstract:
A novel cosmetic composition comprising, in a cosmetically acceptable medium, at least one aminosilicone as defined herein having, for example, a contact angle with water ranging from 90° to 180° and at least one conditioner, being able to afford, for example, at least one improved cosmetic property (such as lightness, disentangling, volume and sheen) and/or at least one of long-lasting and remanent effects, as well as uses of the composition, such as for washing and/or conditioning keratin materials such as the hair or the skin.
Abstract:
The present invention relates to a process for the preparation of a cationic nanoemulsion, to a cosmetic composition obtainable by said process and to the use of said composition.
Abstract:
The present disclosure relates to a cosmetic composition for the treatment of keratinous fibers, such as the hair, comprising at least one polysaccharide chosen from lambda-carrageenans and at least one non-ionic surface-active agent chosen from alkylpolyglucosides, wherein the at least one polysaccharide is present in an amount ranging from 0.1 to 30% by weight of the total weight of the composition. The present disclosure also relates to a cosmetic method for treating keratin fibers and a cosmetic method for fixing and caring for the fibers.
Abstract:
The present invention relates to a composition for washing keratinous substances, preferably keratinous fibers, comprising, in a cosmetically acceptable aqueous medium, at least one anionic or nonionic, amphiphilic linear block copolymer comprising at least one hydrophobic block and at least one hydrophilic block, with the exception of block copolymers of ethylene oxide and of propylene oxide, block copolymers comprising urethane units and block copolymers comprising siloxane units, at least one nonvolatile silicone, and at least one anionic surface-active agent in combination with at least one nonionic and/or amphoteric surface-active agent, and to the use of such a composition for washing keratinous substances.
Abstract:
The invention relates to novel cosmetic compositions comprising, in a cosmetically acceptable medium, at least one fructan, at least one polysaccharide and at least one beneficial agent, a combination which gives the cosmetic compositions a velvety-smooth texture. Said composition can be easily rinsed off. Hair treated with said composition feels soft and contains no residue. The compositions are particularly suitable for washing and/or conditioning keratinous matter, such as the hair and skin.
Abstract:
The present invention relates to a composition for washing keratinous materials, in particular hair, which comprises, in a cosmetically acceptable medium, particles essentially consisting of aluminium oxide and having a mean primary size in numerical terms of less than 200 nm, at least one conditioning agent chosen from cationic surfactants, cationic polymers, silicones, vegetable oils, ceramides, anionic polymers, amphoteric polymers and mixtures thereof, and at least one detergent surfactant, these compositions not simultaneously containing an anionic surfactant and an amphoteric or nonionic surfactant. The invention also relates to a method for the cosmetic treatment of keratinous fibres, and a use of the composition according to the invention as a shampoo.

Abstract:
Processes for preparing 5,8,11-eicosatriynoic acid as well as esters and amides thereof involves initially preparing the acid by reacting 1-decyne with 1,4-dihalo-2-butyne in the presence of a strong base to form 1-halo-2,5-tetradecadiyne which is then reacted with 5-hexynoic acid so as to form 5,8,11-eicosatriynoic acid. This acid can then be converted to the acid chloride form and reacted with an alcohol to form an ester or converted to a potassium salt and reacted with a halide also to form an ester, or after conversion to an acid chloride reacted with an amine in the presence of a tertiary amine to form an amide, or the acid can be reacted with carbonyldiimidazole in the presence of a solvent and excess amine to form an amide.
