摘要:
The invention relates to water-soluble or water-swellable polymers that contain a) 20.0 to 98.97 mole-% of one or more repeating structural units originating from special monomers with sulfonic acid groups or the salts thereof such as e.g. 2-acrylamido-2-methyl-propanesulfonic acid or the salts thereof, b) 1.0 to 60.0 mole-% of one or more repeating structural units containing an amide group and d) 0.01 to 8.0 mole-% of one or more repeating structural units originating from special crosslinking agents with at least three polymerizable double bonds. The polymers for example have an advantageous sensory property profile and are highly suitable as thickening agents even in salt-containing compositions. They are furthermore advantageously suitable for producing cosmetic, dermatological or pharmaceutical compositions.
摘要:
The invention relates to a method for producing fatty acid alkanol amides by reacting at least one amine that contains at least one primary or secondary amino group and at least one hydroxyl group with at least one fatty acid to form an ammonium salt, said ammonium salt being subsequently converted into the alkanol amide by means of microwave radiation.
摘要:
Nanoparticles are claimed which consist of 50-99.99% by weight of alumina and 0.01-50% by weight of metal oxide of elements of main group I and II of the Periodic Table. These nanoparticles are obtained by drying a suspension of aluminum chlorohydrate, oxide formers and, if desired, crystallization nuclei, followed by calcining and comminution of the resultant agglomerates.
