摘要:
A method for preparing macroporous polymethyl methacrylate (PMMA) particles includes the steps of: (a) dissolving a polymethyl methacrylate polymer and Pluronic polymer into an organic solvent; (b) introducing the mixed solution of step (a) to an aqueous solution containing a surfactant to carry out emulsion polymerization; (c) heating the resultant product of step (b) to allow evaporation of the organic solvent; and (d) washing and drying the porous polymethyl methacrylate particles remaining after the evaporation.

摘要:
The invention relates to a cosmetic composition for the treatment of keratinous fibres, in particular human hair, comprising at least one anionic, nonionic, amphoteric or zwitterionic fixing polymer and at least one compound of the ceramide type as well as to the method of treatment using this composition.
摘要:
Oral care compositions comprising one or more active agents and hydroxypropyl cellulose, and that are liquid at or below room temperature and which form a two-phase cloudy system at body temperature. In certain embodiments the active agent is a mineralizing agent, an anti-caries agent, an anti-inflammatory agent, an antibacterial agent, an antifungal agent, an anti-malodour agent or a mixture thereof.
摘要:
The present invention relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least: (a) a supramolecular compound that may be obtained by reaction between: —at least one oil bearing at least one nucleophilic reactive function chosen from OH and NH2, and —at least one junction group capable of establishing hydrogen bonds with one or more partner junction groups, each pairing of a junction group involving at least three hydrogen bonds, the said junction group bearing at least one isocyanate or imidazole reactive function capable of reacting with the reactive function borne by the oil, the said junction group also comprising at least one unit of formula (I) or (II): (b) at least two distinct non-volatile silicone oils chosen from: i) phenyl silicone oils, in particular of formula (II) or (VII) below: ii) linear or cyclic polydimethylsiloxanes (PDMSs), iii) polydimethylsiloxanes comprising alkyl or alkoxy groups, which are pendent and/or at the end of the silicone chain, these groups each containing from 2 to 24 carbon atoms, and (d) at least one agent for structuring the liquid fatty phase.
