  • the dyes which can be used are those substances which are suitable and approved for cosmetic purposes, as compiled, for example, in the publication "Cosmetic Dyes” by the Dye Commission of the German Research Foundation, Verlag Chemie, Weinheim, 1984, pp. 81-106. These dyes are usually used in concentrations of 0.001 to 0.1% by weight, based on the mixture as a whole.
  • the total proportion of auxiliaries and additives can be 1 to 50, preferably 5 to 40,% by weight, based on the composition.
  • the agents can be produced by customary cold or hot processes; the phase inversion temperature method is preferably used.
  • Example 1 200 g (1 mol) of technical lauric acid were placed in a 1 liter stirred autoclave and 6 g of triethanolamine (corresponding to 3% by weight based on lauric acid) were added.
  • the autoclave was alternately evacuated and pressurized with nitrogen three times to remove traces of water that could lead to the formation of polyethylene glycol.
  • the autoclave was closed and heated to 100 ° C. and 44 g (1 mol) of propylene oxide were added in portions at a maximum pressure of 5 bar.
  • stirring was continued for 30 minutes and the reaction mixture was then cooled and let down.
  • the basic catalyst was neutralized by adding an appropriate amount of lactic acid.
  • the characteristics of the lauric acid + 1PO adduct are (quantities as% by weight):
  • a 10% by weight aqueous solution of sodium laureth sulfate was mixed with 2% by weight of the lauric acid propoxylate prepared according to Example 1 with stirring and thickened by adding 1.25% by weight sodium chloride.
  • a viscosity (Brookfield, spindle 1, room temperature, 20 rpm) of 8140 mPas was established. Even after storing the sample for 4 weeks at 40 ° C, the viscosity remained constant.
  • the same fatty alcohol sulfate solution as in the application example was mixed with 3% by weight of the nonionic thickener Laureth-2 and thickened with 1.5% by weight sodium chloride.
  • a viscosity of 8500 mPas was established.
  • the comparative example shows that, with the viscosity to be set approximately the same, smaller amounts of the organic thickener according to the invention (lauric acid + 1 PO) and of thickening sodium chloride are used.

Abstract

L'invention concerne des solutions tensio-actives aqueuses épaissies caractérisées en ce qu'elles contiennent comme épaisissants organiques des alkylèneglycols d'acide gras de la formule (I): R1COO(AlkO)nH, où R1CO représente un reste acyle linéaire ou ramifié, aliphatique, saturé et/ou insaturé avec 6 à 22 atomes de carbone; Alk représente CH¿2?CH2, CHCH3CH2 et/ou CH2CHCH3 et n vaut un chiffre compris entre 0,5 et 5.
