摘要:
The invention provides compositions comprising a) at least one quaternary ammonium compound, and b) at least one polyhydric alcohol having 5 to 12 carbon atoms. The compositions have low setting points, good solubility and dispersibility in aqueous media and a low flash point.
摘要:
Cosmetic, dermatological and pharmaceutical compositions containing quaternary ammonium compounds, particularly for hair-treatment, require low setting points, good solubility and dispersibility in aqueous media and a low flash point. It has now been found that such compositions can be formulated with quaternary ammonium compounds essentially free of short-chain alcohols such as isopropanol. The novel composition comprises: a) at least one quaternary ammonium compound and b) at least one branched alcohol having 8 to 36 carbon atoms or a mixture of at least one branched alcohol and at least one unbranched alcohol having 8 to 36 carbon atoms.

摘要:
The invention relates to pesticide preparations that contain one or more pesticides and one or more N-substituted 2-pyrrolidone-4-carboxylic acid derivatives and to the use of said pesticide preparations for controlling and/or combating weeds, fungal diseases, or insect infestation. The N-substituted 2-pyrrolidone-4-carboxylic acid derivatives act as adjuvants, emulsifiers, dispersants, and/or wetting agents in the pesticide preparations.
摘要:
The invention relates to a continuous method for producing hydroxycarboxylic acid amides, according to which at least one hydroxycarboxylic acid of formula (I) HO—R3—COOH (I) wherein R3 is an optionally substituted aliphatic hydrocarbon group comprising between 1 and 100 carbon atoms, is reacted with at least one amine of formula (II) HNR1R2 (II) wherein R1 and R2 are independently hydrogen or a carbon group comprising between 1 and 100 C atoms, to form an ammonium salt, and said ammonium salt is then reacted to form a hydroxycarboxylic acid amide, under microwave irradiation in a reaction pipe, the longitudinal axis of the pipe being oriented in the direction of propagation of the microwaves of a monomode microwave applicator.
摘要:
Particulate bleach activators comprising 15 to 60% by weight of an acetonitrile, 20 to 70% by weight of a silicon-containing carrier material and 20 to 30% by weight of water, which are obtained by applying an aqueous solution, saturated at 10 to 40° C., of an acetonitrile onto the carrier material without subsequent drying, where the amount of saturated aqueous solution is measured such that the given limits for acetonitrile, carrier material and water are observed.
摘要:
A description is given of cosmetic and pharmaceutical preparations comprising I) one or more water-soluble noncrosslinked copolymers containing A) one or more structural units of the formula (1) and B) one or more structural units of the formula (2) and II) one or more water-soluble or water-swellable crosslinked or noncrosslinked copolymeric or homopolymeric thickeners.
摘要:
The invention relates to suspension concentrates comprising a) one or more pesticides that are solid at room temperature, b) one or more specific copolymers, c) one or more additional auxiliary substances as applicable and d) one or more solvents. The copolymers b) comprise structural units of formula (I), wherein A stands for C2-C4-alkyls, B stands for a C2-C4-alkyl different from A, R stands for hydrogen or methyl, m is a number from 1 to 500, n is a number from 1 to 500, the sum of m+n is equal to 2 to 1000 and P stands for H or for a specific other concluding group, and structural units derived from specific ethylenic, unsaturated monomers that comprise an aromatic group, and structural units derived from specific ethylenic, unsaturated monomers that comprise aliphatic hydrocarbon residue. The suspension concentrates according to the invention are advantageously suitable for use as pesticides.
