摘要:
A one-step process for preparing cross-linked poly-.beta.-alanine as microspheres having narrow size distribution comprises polymerizing acrylamide with a polyfunctional compound copolymerizable with acrylamide (with the polyfunctional compound also acting as the cross-linking agent) in an organic solvent or a mixtured such solvents in the presence of an ionic polymerization initiator and a suspension agent. The resulting microspheres may be impregnated with a pharmaceutically or cosmetically active substance.
摘要:
A process for preparing crosslinked poly .beta.-alanine in the form of microspheres comprises (a) polymerizing acrylamide in a tert. butanol/toluene solvent mixture in the presence of a polymerization initiator and an octadecene-maleic anhydride copolymer as a suspension agent; (b) submitting the resulting suspension of poly .beta.-alanine to a crosslinking reaction using a dialdehyde as the crosslinking agent; and (c) isolating the crosslinked poly .beta.-alanine microspheres. These microspheres exhibit a low size dispersity.
摘要:
A means of reinforcing and/or mechanically deforming human hair, comprising a first stage in which the hair undergoes the action of a reducing agent so as to break the disulfide linkages of the keracystine to form thiol groups, followed by the application in a second stage of a modifying agent encouraging the establishment of new chemical linkages to the thiol groups, characterized in that the aforesaid modifying agent is a polyhaloacetylated polymer whose halogen atom is capable of reacting with thiol groups.

摘要:
A cosmetic composition in the form of an aerosol spray for hair control contains a solvent; a film-forming tetrapolymer resulting from the copolymerization of (a) 5 to 10 wt. % acrylic acid, (b) 20 to 52 wt. % N,N-dimethylacrylamide, (c) 3 to 28 wt. % of N-tert-butylacrylamide, and (d) 20 to 45 wt. % ethyl methacrylate, the carboxylic acid functions of the tetrapolymer being at least partially neutralized with a mineral or organic base; and at least one non-halogen propellant gas. This spray provides excellent hair control, and the film-forming substance does not cause stickiness of the hair over time and is easily eliminated by washing with a shampoo.
