Embodiment

[0153] Table A: With two hydroxyethyl and fatty alcohol groups R 1 Amines

[0154]

[0155] Table B: Group R 3 or, if appropriate, define R 5 of fatty acids

[0156] fatty acid source iodine value FS1 Coconut Fatty Acid, Wilfarin DC-0818, Wilmar <12

Embodiment B1 to B6

[0158] 482.8 g (1.325 mol) of amine A1 were placed in a three-necked flask equipped with column, distillation system and stirrer motor and heated to 80° C. under nitrogen atmosphere. 332.8 g (1.59 mol) of fatty acid FS1 and 0.4 g of a 50% aqueous solution of hypophosphorous acid were added thereto. A vacuum of 100 mbar was applied and the mixture was carefully heated to 195° C., with water of reaction collecting in the effluent of the distillation system. After 3 hours, the vacuum was reduced to 20 mbar and the reaction continued for 2 hours. The condensation product thus obtained had an acid number of 1.3 mg KOH / g and an amine number of 94.0 mg KOH / g. The reaction mixture was cooled to 80 °C. Within 1 hour, 155.4 g (1.232 mol) of dimethyl sulfate were added dropwise with stirring, keeping the temperature in the range of 80°C to 95°C. Subsequently, 103 g of absolute ethanol were added, and the mixture was further stirred at 80° C. for 1 hour. The product thus obtained had ...

Embodiment B9

[0163] First, 89.8 g (0.445 mol) of lauric acid, 125.7 g (0.445 mol) of oleic acid and 209.5 g (0.897 mol) of behenic acid were added at 70°C. In a three-necked flask equipped with a distillation column attachment, 324.9 g (0.938 mol) of N,N-bis(2-hydroxyethyl)-N-octadecylamine was added dropwise, and the mixture was slowly heated to 190 °C, the water of reaction was distilled off. After 2 hours, a vacuum of 25 mbar was applied, which was then further reduced to 8 mbar. After 8 hours, the acid value reached 3.5 mgKOH / g. The reaction mixture was cooled to 60 °C. 771.4 g of the diester thus obtained were mixed with 448 g of C16 / C18 fatty alcohol. 101 g (0.80 mol) of dimethyl sulfate was gradually added to the reaction mass and reacted at 80-90°C. The product thus obtained had a total amine value of 2.9 mgKOH / g.

Abstract

The invention relates to compositions comprising A) at least one hybrid quat and B) at least one fatty alcohol.

Description

technical field [0001] The present invention relates to compositions comprising: [0002] A) at least one mixed quaternary ammonium salt, and [0003] B) at least one fatty alcohol. Background technique [0004] Alkylquats and esterquats are used as hair conditioning agents in cosmetic formulations. Both have some disadvantages: Alkyl quaternary ammonium salts (especially dialkyl quaternary ammonium salts) are usually poorly biodegradable and pollute the environment. Esterquats (especially TEA esterquats) are sensitive to hydrolysis and therefore have limited use in aqueous formulations. [0005] It can now be seen that alkyl ester quats (mixed quats) consisting of ammonium salts having at least one fatty alkyl chain and at least one ester group esterified with a fatty acid have excellent conditioning properties without at the same time It has the disadvantages of alkyl quaternary ammonium salt or ester quaternary ammonium salt. [0006] Surprisingly, it has additionall...
