Abstract

What are described are compositions comprising a) one or more sugar amines of the formula (I) in which R1 and R2 are independently H, CH.sub.3 or 2-hydroxyethyl and/or one or more corresponding protonated sugar amines with the counterion RCOO in which R is defined as R from the substances of component b) below, and b) one or more substances selected from the group consisting of fatty acids of the formula RCOOH, fatty acid salts of the formula RCOO-M+ and mixtures thereof, in which R is a linear or branched saturated alkyl radical having 11 to 21 carbon atoms or a linear or branched, mono- or polyunsaturated alkenyl radical having 11 to 21 carbon atoms and M+ is a counterion. The compositions described are very advantageous, for example, for production of liquid washing compositions, and of shower gels, liquid soaps or face cleansers. In addition, the sugar amines are advantageously suitable as neutralizing agents for fatty acids.

Description

EXAMPLE 1

[0102] 5 g of oleic acid were introduced into 95 g of water (two-phase) and admixed with increasing molar amounts of different neutralizing agents up to 100 mol % of neutralizing agent. During this, the viscosity was determined (Brookfield, 20 C., 20 revolutions per minute (rpm), spindle 1 or 2), the homogeneity of the resulting solution was observed and the pH was measured (see table 1).

[0103] The following values are listed in table 1 and the following abbreviations were used therein:

[0104] The upper number in the respective lines of table 1 gives the measured viscosity in mPa.Math.s.

[0105] T means: the solution is two-phase.

[0106] C means: the solution is clear.

[0107] H means: the solution is homogeneous, but cloudy.

[0108] The lower number in the respective lines of table 1 gives the measured pH. Here, n.d. means not determined.

[0109] It can be seen from the values in table 1 that in the case of neutralization of oleic acid with dimethylglucamine, low viscosity, homogeneous solutions result even at low degrees of neutralization. Homogeneous solutions are already obtained above a pH of 8.0.
