The invention relates to clear, liquid preservatives, which contain a) one or several 1-hydroxy-4-methyl-6-alkyl-2(1H)-pyridones and/or one or several salts thereof. wherein alkyl represents a linear, branched or cyclic alkyl group having 1-12 carbon atoms, and b) one or several alcohols containing one or several aromatic groups.
摘要:
Linear organopolysiloxane-polyoxyalkylene copolymers of the formula (I) are described, in which R1 and R2, independently of one another, are a straight-chain or branched, saturated alkyl group having 6 to 22 carbon atoms or are a straight-chain or branched, mono- or polyunsaturated alkenyl group having 6 to 22 carbon atoms, R3, R4, R5, R6, R7 and R8, independently of one another, are a straight-chain or branched, saturated alkyl group having 1 to 30 carbon atoms, a straight-chain or branched, mono- or polyunsaturated alkenyl group having 2 to 30 carbon atoms or a phenyl radical, m and p are numbers from 4 to 50 and n is a number from 3 to 90. The linear organopolysiloxane-polyoxyalkylene copolymers of the formula (I) can be used in an advantageous way in cosmetic or pharmaceutical compositions. Moreover, they are suitable particularly for the cleansing and care of the hair and the skin, as emulsifier in emulsions, preferably in O/W or W/O emulsions, and as conditioners.
摘要:
The invention provides an explosive composition comprising A) an oxygen-donating constituent, which forms a disperse phase, B) an organic constituent, which forms a dispersion phase, and C) at least one emulsifier, wherein the emulsifier includes a copolymer comprising, in random or regular order, structural units derived from a) maleic anhydride, b) one or more olefins having more than 40 carbon atoms, and c) a vinyl ester of carboxylic acids having from 2 to 12 carbon atoms, where the structural units derived from maleic anhydride have been modified by reaction with alcohols, amino alcohols, ammonia or amines.
摘要:
An additive for inhibiting the formation of gas hydrates in connection with hydrocarbon production and transportation comprising the water-soluble polymers comprising structural elements of the formula wherein each R is independently H or C1-C5-alkyl; X is H, an alkaline or earth alkaline metal or a quaternary ammonium group; R1 is H or C1-C18-alkyl; and R2 is C1-C18-alkyl; and wherein the alkyl groups represented by R1 and R2 optionally carry a hydroxy or amino substituent; and, optionally, a minor proportion of structural elements of the formula wherein R, R1, R2 and X may have the meaning as above, and Alk is a C1-C5-alkylene chain.
摘要:
A description is given of compositions comprising a) one or more substances selected from the group consisting of hydrogen peroxide and hydrogen peroxide donor substances, b) water, c) one or more polymers having thickening properties and d) one or more substances selected from the group consisting of hydroxypyridones and salts thereof. The compositions are notable more particularly for their advantageous shelf lives.
摘要:
The invention relates to compositions containing a) one or more substances selected from the group of hydrogen peroxide and substances releasing hydrogen peroxide, b) water, d) one or more substances selected from the group consisting of hydroxypyridones and the salts thereof, characterized in that said compositions do not comprise polymers having thickening properties. The compositions are particularly characterized by the advantageous storage stability thereof.
摘要:
The invention relates to a composition which contains at least one anionic surfactant, a betaine surfactant, a mixture of N-methyl-N-acylglucamines, the acyl groups of which correspond to those of natural coconut oil and/or palm kernel oil, a glycerol derivative, a solvent and optionally one or more additives. The invention also relates to a method for producing the composition. The invention further relates to the use of the composition for the treatment or care of skin or hair, for example as a shampoo, face cleaner, liquid cleaner or shower gel.
摘要:
The present invention relates to leave-on compositions for personal care comprising trimethylsilylalkylsilsesquioxanes, particularly trimethylsilyl-n-octylsilsesquioxanes (Caprylyl Trimethicones). Said trimethylsilylalkylsilsesquioxanes are especially useful in formulating emulsions.
