Description

A substance that has a cleansing and skin care property

The invention relates to a substance having a cleansing and skin-care property, based on a combination of surfactants and a cationic polymer, which can be used advantageously as a foam or shower gel.

Foam and shower gel compositions contain, as cleaning agents, the usual anionic surfactants, for example alkali metal salts of alkyl or alkyl ether sulphates, disodium salts of sulphosuccinic acid half-esters or protein / fatty acid condensation products.

In addition, higher quality foam and shower gel compositions may contain non-ionizable and amphoteric surfactants. Examples of non-ionizable surfactants which may be mentioned are fatty acid alkylamides, amino oxides, polyglyceryl ethers, saturated and unsaturated fatty alcohols and alkylphenols, while amphoteric surfactants include, for example, alkylamidobetaines, alkylobutanidines, sulfobetaines, sulfobetaines.

Such foam and shower gel compositions are described, for example, in the following references: H. Janistyn, "Handbuch der Kosmetika und Riechstof-25 fe", (1973) 3rd edition, pages 442-453 and Seifen-ÖLe-Fette-

Wachse 94, (1968), from page 475 onwards.

However, the use of the above surfactants in foam and shower gel compositions, either alone or in admixture, can cause the user to feel and dry the skin. The aim is to eliminate this disadvantage by adding therapeutically active ingredients such as those recommended in the following literature references: H. Janistyn, "Handbuch der Kosmetika und Wirkstoffe", 3rd edition, 1973), from page 445 onwards, 35 company name Henkel, "Kosmetik Modell-Rezeptu - ren ", published in 1979, and the German application publication 2 87139 DE-OS 3 302 456. ethoxylated and propoxylated, saturated fatty alcohols, fatty acid esters, fatty acid glycerides, fatty acid isopropyl esters, cellulose ethers, quaternary cellulose-5 ethers, chitin derivatives and quaternary chitin derivatives.

The subjective effect of the treatment on the skin is undoubtedly small after the use of foam and shower-bath compositions containing the above-mentioned therapeutic ingredients, and therefore they are hardly noticed by the user.

Highly therapeutic compositions that impart a clear, pleasant and well-treated feeling to the skin include oil baths and oil foam baths.

15 However, these pure oil baths have no cleansing effect and, due to their lipophilic compositions, oil foam baths are limited to very specific, low aqueous surfactant solutions and oil components.

Such oil-foam baths, which are known, for example, from DE-OS 2 943 202 and EP-PS 26 073, are generally single-phase compositions in which the water content is limited to a maximum of 15% by weight in order to guarantee the dissolution of the oil component. as a clear solution in surfactants.

It is therefore an object of the invention to provide a substance having a cleansing and skin-care property which combines the advantage of oil-only or oil-changing baths, namely a strong skin-care effect, with the advantage of foam and shower-only baths, namely excellent foaming, without special low-water surfactant solutions and an oil component must be used.

It has now been found that the object is solved in an excellent manner by a substance having a cleansing and skin-care property and based on a combination of surfactants and cationic polymers, which substance is characterized in that it contains A) 12.0-24.0 by weight of an alkylamidobetaine of the general formula (I) 50 (-Γ) CH 2 O (i / t 3 o, T, 9 -c-nh-ch2ch2ch2 -n-ch2coo ^ ci), CH3 in which R represents an alkyl residue in which has 7-17 hii-10 liatoms,

In order to demonstrate the class-specific cleansing and skin-care properties of the substance according to the invention, which can only be achieved by using components A) to E) in the above-mentioned weight ratio of 5, comparative experiments were carried out, which are described below.

Example 1,182 subjects aged 20-45 years evaluated the subjective treatment effect on the skin after use of the foam bath composition (X) of the invention by comparing it to a similar foam bath composition (Y) known in the art. The test compositions were bottled in neutral and used an average of 3 times with an average bath time of 15 to 20 minutes.

Substance (X) of the invention had the following composition: (a) 58.0 g of 1-coconut amido-3- (dimethylcarboxymethyl) ammoniopropane, 30% aqueous solution 20 (b) 5.8 g of 1-coconut amido 2- (Dicarboxymethyl-2'-hydroxyethyl) -ammonioethane, 50% aqueous solution (c) 4.5 g of sodium lauryl sulphate, solid, 90.5% (d) 2.2 g of poly-N- [3- (dimethylammonio) propyl] -N'-E- (ethyleneoxyethylene dimethylammonio) propyl-25-urea dichloride, 64% aqueous solution 2.0 g turbidity agent 1.1 g perfume oil, colorant (e) 26.5 g water 100, 0 g 30 A prior art foam bath (Y), the ingredients of which in a similar composition are known, for example, from the trade name Henkel, "Kosmetik Modell-Rezepturen" (1979), pages 181, 182, and from AT application 5 283/80, had the following composition: : l! 7 87139 57.0 g sodium lauryl ether sulphate, 28% aqueous solution 3.5 g 30 mol of ethylene oxide oxyethylated monococcal fatty acid glyceryl ester 5 23.0 g protein / fatty acid condensation product, 30% aqueous solution 0.5 g odorant 2.5 g odor 2.5 g odor 2.5 g 13.4 g of water 100.9 g

While the subjects rated the dissolution and foaming capabilities of the foam bath compositions (X) and (Y) approximately as good, the foam bath composition (X) of the invention proved to be clearly superior to the reference composition (Y) and the softness and elasticity of the skin after use and treatment. that also in the overall review. This is clear from the experimental results presented in the following tables.

Further evidence of the excellent therapeutic effect of the foam bath composition 10 (X) of the invention is provided by the numerous use of body lotion after bathing. When 99 subjects applied body lotion after the use of the prior art foam bath composition (Y), this was the case with the use of the new foam bath composition 15 (X) for only 72 subjects.

Another comparative experiment was carried out comparing the foam bath (X) of the invention with the following cosmetic properties in cosmetic properties, but having a similar composition (Z), but based on an alkyl ether sulfate surfactant known in the art.

(a) 15.0 g of coconut fatty acid amidopropyl-betaine, 30% aqueous solution (b) 10.5 g of 1-coconut amido-2- (dicarboxymethyl-2'-hydroxyethyl) -ammonioethane, 50% aqueous solution 21.0 g of sodium lauryl ether sulfate, 27% aqueous solution (D) 2.1 g of poly-N- [4- (dimethylammonio) propyl] -30N '- [3- (ethyleneoxyethylene dimethylammonium) propyl] urea dichloride A 64% aqueous solution of 51.4 g of water 100.0 g 9 87139

Result: All subjects blamed the deficient foaming of composition (Z). The skin-treating properties of the composition (X) according to the invention were judged to be clearly superior to the corresponding properties of the composition (Z).

When the agent (X) of the invention contains an alkyl sulfate salt as an active detergent, an alkyl ether sulfate salt is used in the reference agent compositions (Y) and (Z). It is known that both alkyl sulfate salts and alkyl ether sulfate salts have quite good basic properties. Compared to alkyl sulfate salts, alkyl ether sulfate salts (see, for example, K. Schrader, Seifen-Öle-Fette-Wachse 111, (1985) 41) are much more suitable for the skin and less roughening of the skin. The clear superiority of the alkyl sulfate salt of the agent of the invention in terms of skin care properties is thus a surprising fact.

Example 2 Foam and Shower Bath Composition 20 (a) 55.0 g of 1-coconut amido-3- (dimethylcarboxymethyl) ammoniopropane, 30% aqueous solution (b) 6.0 g of 1-coconut amido-2- (dicarboxymethyl) 2 '- (hydroxyethyl) ammonioethane, 50%; . 25 aqueous solutions: (c) 4.5 g of sodium lauryl sulphate, solid, '90.5% V' (d) 2.2 g of poly-N- [3- (dimethylammonio) propyl] -N '- [3- (ethyleneoxyethylene) -dimethyl-20 ammonio) propyl / urea dichloride, 64% aqueous solution (e) 32.3 g water 100.0 g lft 87139 10

To prepare the above-mentioned foam and shower gel composition, component (c) is first dissolved in water. This solution is then added with stirring to a homogeneous mixture of components (a), (b) and (d).

5 All dissolution and mixing steps are performed at room temperature.

The foam and shower gel composition obtained in this way has a fairly good foaming ability and leaves an excellent healing feeling on the skin after use.
