摘要:
The present invention relates to cosmetic or dermatological formulations comprising at least one active compound, at least one polymer which is molecularly imprinted in the presence of this active compound and at least one fatty phase.
摘要:
The present invention relates to the use of copolymers obtainable by copolymerization of at least one ethylenically unsaturated dicarboxylic acid anhydride derived from at least one dicarboxylic acid having 4 to 8 carbon atoms and at least one oligomer of branched or unbranched C3-C10-alkene, where at least one oligomer has an average molecular weight Mn in the range from 300 to 5000 g/mol, preferably up to 1200 g/mol or is obtainable by oligomerization of at least 3 equivalents of C3-C10-alkene, in cosmetic compositions.
摘要:
The cosmetic or dermatological formulations of the invention include: (a) at least one oxidation-sensitive or UV-sensitive active ingredient, (b) at least one dialkyl naphthalate which is distinguished by the structural formula in which R1 and R2, independently of one another, are chosen from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms, and (c) at least one wax and/or one oil thickener. The present invention also includes methods of using the cosmetic or dermatological formulations.
摘要:
Cosmetic and dermatological formulations comprising at least one hydrophilic active ingredient and at least one dialkyl naphthalate which is characterized by the structural formula in which R1 and R2, independently of one another, are selected from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms, have been found to be stable and effective, particularly in moisturizing the skin or protection the skin from skin aging.
摘要:
An active ingredient combination effective for light protection and composed of (a) one or more UV filter substances selected from the group of benzotriazole derivatives and (b) one or more dialkyl naphthalates having the structural formula in which R1 and R2 are, independently of one another, selected from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms.
摘要:
The present invention relates to novel polyurethanes and to mixtures of such polyurethanes, to processes for their preparation, to their use for producing preparations comprising water and to preparations which comprise the polyurethanes. In particular, the invention relates to water-dispersible polyurethane with an essentially linear backbone composed of alternating hydrophilic and hydrophobic sections.
摘要:
The present invention relates to a process for preparing polyurethanes, which comprise at least three hydrophilic sections, at least four hydrophobic sections, optionally allophanate segments and/or isocyanurate segments and which are prepared in the presence of alkali(ne earth) metal carboxylates. The process may comprise using at least one carboxylic acid salt of at least one metal selected from the group consisting of the alkali metals, the alkaline earth metals and mixtures thereof Furthermore, the present invention relates to the polyurethanes per se obtainable in this way, to the use thereof as thickeners for aqueous preparations, and to preparations comprising polyurethanes of this type.
摘要:
The present invention relates to associative polyurethane thickeners which comprise hyperbranched polymers in polymerized-in form, to the preparation of these thickeners, and to the use thereof, particularly in cosmetic preparations.
