The compositions are distinguished in particular by an advantageous antimicrobial activity.
摘要:
A process for preparing acylglycinates of the formula (I) wherein R1 is a linear or branched, saturated alkanoyl group having 6 to 30 carbon atoms, or is a linear or branched, singly or multiply unsaturated alkenoyl group having 6 to 30 carbon atoms, and Q+ is a cation, wherein glycine is reacted with fatty acid chloride R1Cl, in water and in the presence of a basic alkali metal compound which yields cations Q+, but in the absence of organic solvents, at 25-50° C. Also described are compositions comprising acylglycinates of the formula (I).
摘要:
The use of one or more compounds of the formula (I) in which R is a straight-chain or branched saturated alkyl group having 5 to 11 carbon atoms or a straight-chain or branched mono- or polyunsaturated alkenyl group having 5 to 11 carbon atoms as thickeners is described. The use is preferably in cosmetic, dermatological or pharmaceutical compositions, in crop protection formulations, in washing or cleaning compositions or in paints or coatings.
摘要:
What are described are compositions comprising one or more compounds of the formula (I) and one or more compounds of the formula (II) in which R, Ra and Rb each independently of one another are straight-chain or branched saturated alkyl groups having 5 to 11 carbon atoms or straight-chain or branched mono- or polyunsaturated alkenyl groups having 5 to 11 carbon atoms, wherein the total amount of the compounds of the formulae (I) and (II), based on the total weight of the compositions, is at least 60% by weight. In an advantageous manner, the compositions are suitable for producing cosmetic, dermatological or pharmaceutical compositions, crop protection formulations, washing or cleaning compositions or paints or coatings.

摘要:
A process is described for preparing acylglycinates of the formula (I) wherein R1 is a linear or branched, saturated alkanoyl group having 6 to 30 carbon atoms, or is a linear or branched, singly or multiply unsaturated alkenoyl group having 6 to 30 carbon atoms, and Q+ is a cation selected from the alkali metals Na+ and K+, the process being characterized in that glycine is reacted with fatty acid chloride R1Cl, wherein R1 possesses the definition stated in formula (I), in water and in the presence of a basic alkali metal compound which yields cations Q+ selected from Na+ and K+, but in the absence of organic solvents, at 25-50° C., and the fraction of fatty acid chloride R1Cl containing unsaturated acyl groups R1 having 18 carbon atoms, based on the total amount of fatty acid chloride used, is greater than or equal to 2.0% by weight, and at the same time the fraction of fatty acid chloride containing saturated acyl groups having 8 and 10 carbon atoms, based on the total amount of fatty acid chloride used, is greater than, or equal to in each case 3.0% by weight. Also described are compositions comprising acylglycinates of the formula (I).
摘要:
The invention relates to liquid compositions which contain a) from 5 to 95% by weight of sorbitan monocaprylate and b) from 5 to 95% by weight of one or more alcohols of formula (1) R—OH (1), wherein R is a group consisting of carbon, hydrogen and optionally oxygen atoms with 5 to 12, preferably 6 to 11, carbon atoms, and the carbon atoms can be interlinked in, a linear, branched and/or cyclic fashion via saturated, unsaturated and/or aromatic carbon-carbon bonds and the groups can also contain ether units and hydrogen atoms and/or hydroxyl groups can be bound to the individual carbon atoms. The liquid compositions are suitable for the production of cosmetic, dermatological or pharmaceutical products.
摘要:
A method is described for producing acyl glycinate salts of formula (II) in which R1 represents a saturated linear or branched alkyl radical comprising 1 to 21 carbon atoms or a monounsaturated or polyunsaturated linear or branched alkenyl radical comprising 2 to 21 carbon atoms, and B represents a cation, and/or the corresponding protonated acyl glycinic acid. Said method is characterized in that one or more fatty acid monoethanol amides of formula (I) in which R1 has the meaning indicated above is/are oxidized with oxygen in the presence of an optionally supported bimetallic catalyst consisting of gold and a metal from group VIII of the periodic table in the alkaline medium in order to obtain one or more acyl glycinate salts of formula (II). In order to produce the protonated acyl glycinic acids, the acyl glycinate salt/s of formula (II) is/are additionally reacted with an acid.
