Description

The invention relates to bath foam with increased foam stability.

The essence of the bath foam according to the invention, which contains a surfactant, water, plant extracts, fragrance compositions, a coloring agent and possibly other natural and synthetic substances, consists in that it contains, as active ingredient, a fatty acid 3- (hydroxylamino) -2-hydroxypropyl ester of formula I

R-COO-CH ₂ -CH (OH) CH ₂ N (I) wherein R represents an alkyl or alkenyl group having 6 to 22 carbon atoms in the main chain,

R 1 denotes 2-hydroxyethyl, 3-hydroxypropyl,

1-hydroxy-2-propyl, 2-hydroxy-1-propyl, 1-hydroxy-2-butyl, 1-hydroxy-3-butyl, 1-hydroxy-4-butyl,

2-hydroxy-3-butyl,

R ,, R ₂ represents hydrogen, in a concentration of 2-35% by volume, preferably 5-30% by volume.

The formulation according to the invention has a foam stability according to a standard test 30% higher than conventional bath foams.

The invention relates to bath foam with increased foam stability.

Bath foam is first and foremost a detergent, but it also has other essential functions: it is a very good thermal insulator that prevents the bath from cooling and is a carrier of substances with cosmetic and ionizing effect. In particular, it is desirable that the foam be sufficiently stable while maintaining all other effects. Both foam stabilizers and dermatological reasons added to the thickener adversely affect the washing performance.

This disadvantage is overcome by the bath foam according to the invention. The essence of the bath foam according to the invention, which contains a surfactant, water, plant extracts, fragrance compositions, a coloring agent and possibly other natural and synthetic substances, consists in that it contains, as active ingredient, a fatty acid 3- (hydroxylamino) -2-hydroxypropyl ester of formula I

R-C00-CH ₂ -CH (OH) CH ₂ N wherein R is alkyl or alkenyl having 6-22 carbon atoms in the main chain, R ₁ represents 2-hydroxyethyl, 3-hydroxypropyl,

1-hydroxy-2-propyl, 2-hydroxy-1-propyl,

1-hydroxy-2-butyl, 1-hydroxy-3-butyl,

1-hydroxy-4-butyl, 2-hydroxy-3-butyl,

R ₂ denotes R ₁ , hydrogen, in a concentration of 2 to 35% by volume, preferably 5 to 30% by volume.

Example 1

Ingredients:

sodium lauryl sulphate or sodium lauryl ether sulphate fatty acid amines (C 12) foam stabilizer

1% plant extracts in ethanol or water

5% solution of food colorings in ethanol odorous composition Compound of formula I wherein R = a mixture of aliphatic radicals ^G 8 ^G 18 of coconut oil, R 1 = R ₂ = CH ₂ CH ₂ OH distilled (I) water 12% v / v 15 % by volume 15% by volume 3% by volume 2% by volume% by volume residue up to 100%

The composition of Example 1 is prepared by first mixing the compound of formula I in water with 5% sodium lauryl sulfate or sodium lauryl ether sulfate, then adding the other components of the mixture and the rest of the lauryl sulfate in the usual manner. This example essentially represents the addition of a compound of formula I to an existing formulation. The stability of the foam as well as the feeling of relaxation and softness of the skin has improved. The foam stability according to the standard test (shaking in a glass cylinder) is 30% higher than conventional bath foams.

Example 2

Ingredients:

sodium lauryl sulphate or sodium lauryl ether sulphate 5% solution of food colors in ethanol

1% plant extracts in ethanol or water% by volume 1% by volume 7% by volume of the substance of the general formula I, where R = CK ^ (CH ₂ ), q SpR ₂ -CH ₂ CK ₂ OH water distilled% by volume residue up to 100%

The composition of Example 2 is prepared by first mixing the compound of formula I in water with 1 to 5% sodium lauryl sulfate or sodium lauryl ether sulfate, then adding the other components to the mixture and the remainder of the lauryl sulfate in a conventional manner.

In this example, both the foam stabilizers and the thickener are completely omitted, providing high quality and stable foam. Although the surfactant content is reduced compared to Example 1, an excellent washing effect was achieved. The feeling of freshness, relaxation and softness of the skin is very good. The viscosity of the formulation is increased even at concentrations above 15%, a preferred pasty consistency with very good warm bath solubility is achieved. The foam stability according to the standard test (shaking in a glass cylinder) is 30% higher than conventional bath foams.
