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.

摘要:
Stable liquid cosmetic or dermatological cleansing compositions comprising one or more secondary alkanesulfonates and one or more betaines are described, wherein the weight ratio of alkanesulfonate to betaine is from 6:3 to 1:2 and the viscosity of the cleansing composition is between 1000 and 30 000 mPas.
摘要:
The invention relates to the use of compounds of the formula (1) in which R1 is C1- to C24-alkyl, C2- to C24-alkenyl or a C6- to C18-aryl radical which may be substituted by a C1- to C24-alkyl group, R2, R3 independently of one another, are hydrogen, C1- to C18-alkyl, or C8- to C7-cycloalkyl, or R2 and R3, including the nitrogen atom to which they are bonded, form a ring of 4 to 8 ring atoms, in which oxygen or nitrogen atoms may also be present in addition to carbon. A are identical or different C2- to C4-alkylene radicals, B is C1- to C7-alkylene, and n is an integer from 1-40, as gas hydrate inhibitors.

摘要:
The invention relates to the use of compounds of the formula (1) in which R1 is C1-C30-alkyl, C2-C30-alkenyl or a group of the formula —CH2—CO—NR2R3 or a C6-C18-aryl radical which may be substituted by a C1-C12-alkyl group, R2, R3 independently of one another, are hydrogen, C1-C6-alkyl or C5-C7-cycloalkyl, or R2 and R3, including the nitrogen atom to which they are bonded, form a ring of 4 to 8 ring atoms, it being possible for the ring also to contain oxygen or nitrogen atoms in addition to carbon atoms, A is a C2-C4-alkylene radical and n is an integer from 1 to 20, as gas hydrate inhibitors.
摘要:
This invention relates to liquid rinse-off compositions for personal care comprising trimethylsilylalkylsilsesquioxanes, particularly trimethylsilyl-n-octylsilsesquioxanes (Caprylyl Trimethicones). Preferably the rinse-off compositions are shampoos containing pearlescent and/or opacifying agents.
摘要:
