Description

The The present invention relates to the use of a shampoo with optimal properties.

conditioning Shampoos have been known for years and have been on the Market proved to be very successful.

such Shampoos usually contain at least one surface-active Substance, in particular an anionic surfactant, and a hair conditioning Polymer, preferably a cationic.

Even though these products prove themselves There is still a need to improve their Efficacy, especially in terms of volume, gloss, combability and feeling of the hair washed with it.

Furthermore is expected from a shampoo good foaming power and a high foam volume. After all Shampoos should also be extremely mild, d. h., a complete skin and mucosal compatibility exhibit.

It it has now been found that one gets a shampoo, which optimally meets these requirements, especially for fine hair, though this shampoo on an aqueous basis as defined in claim 1. The feature "free of cationically derivatized Panthenol is " represents an invalid Extension.

From the US 4,364,837 For example, aqueous shampoo formulations are known which contain from 3 to 60% by weight of an anionic surfactant, from 0.1 to 30% by weight of a nonionic or cationic hair conditioning substance and from 1 to 70% of a water-miscible saccharide.

this Compositions can if appropriate, amphoteric or zwitterionic surfactants are added become.

From the EP 625 041 B1 Aqueous body cleansing compositions are already known, comprising a mixture of 0.5 to 35 wt .-% saponin (s), 0.1 to 35 wt .-% lecithin (s) and / or oligopeptides (s) and 0.1 to 20 Wt .-% mono- and / or oligosaccharides. As surfactants, ampholytic and zwitterionic surfactants are preferred.

With These known mixtures can be achieved with the compositions of the invention Properties, in particular hair conditioning and softening Effect, not achieve.

Furthermore impaired a sugar content in this high concentration the additive and the stability various active ingredients in shampoos as well as the application technology Properties.

The DE 44 40 315 A1 describes hair-generating preparations containing an active ingredient complex of a cationically derivatized panthenol and a carbohydrate, in particular for the treatment of hair splitting.

such cationically derivatized panthenols are used in the invention Shampoos not needed and have become incompatible with anionic shampoo basics as well proved.

Suitable anionic surfactants in the context of the invention are contained in an amount of 5 to 50 wt .-%, preferably 10 to 25 wt .-% of the composition. These are those of the sulfate, sulfonate, carboxylate and alkyl phosphate type, especially of course those which are commonly used in shampoos, for example the known C ₁₀ -C ₁₈ alkyl sulfates and in particular the corresponding ether sulfates, for example C ₁₂ -C ₁₄ -alkyl ether sulfate, lauryl ether sulfate, in particular having 1 to 4 ethylene oxide groups in the molecule, furthermore monoglyceride (ether) sulfates, fatty acid amide sulfates which are obtained by ethoxylation and subsequent sulfation of fatty acid alkanolamides, and their alkali metal salts and salts of long-chain mono- and dialkyl phosphates, which are mild, skin-friendly detergents.

Suitable are both volatile as well as semi-volatiles cyclic or linear polysiloxanes, for example those under the Trivial names "Dimethicone" or "Phenyldimethicone" and "Cyclomethicone" known silicone oils.

Suitable, for example, in the EP 398 177 A2 described silicone derivatives which are used there in combination with alkyl polyglucosides in liquid detergent compositions.

The used according to the invention Shampoos can also contain dyes for the direct or oxidative coloring of hair, So-called tinting or dye shampoos.

Of the pH of the invention used Shampoos is in the usual Range between about 5 and 8.5; For special products he can too be set below 5.

The following examples serve to illustrate the invention. The preparation of the products used in the invention is carried out by stirring the individual components in water, whereby premixes of various components can be used. example 1 (Wt .-%) C ₁₂ -C ₁₄ fatty alcohol ether sulfate 10.0 C ₈ -C ₂₂ -alkyl glucoside (PD: ~ 1.5) 5.0 sodium lauroyl 2.0 cocoamidopropyl 3.2 Cationic Polymer (Polyquaternium-7) 0.1 sodium benzoate 0.6 sodium sorbate 0.3 sucrose 0.5 peach oil 0.1 Perfume 0.7 PEG-60 hydrogenated castor oil 0.5 Benzophenone-3 0.1 sodium chloride qs water ad 100.0

This Shampoo was in the known half-page double blind trial on 10 subjects compared with a shampoo that does not contain sucrose and instead 0.5 wt .-% more water.

The independent Evaluation by two hairdressers revealed a preference of 9: 1 in favor of the inventive Shampoos with regard to foam properties and wet and dry combability, the suppleness and looseness of wet, washed hair and 8: 2 in favor of the shampoo according to the invention in view of Volume, softness and bounce of dry hair.

The omission of the alkylglucoside and complete replacement thereof with fatty alcohol ether sulfate resulted in a less foaming composition, whereby combability, volume and bounce as well as the gloss of the washed hair compared to the shampoo according to the invention were markedly reduced. Example 2 (Wt .-%) Sodium Lauryl Ether Carboxylate (10EO) 5.0 Dinatriumlaurylethersulfosuccinat 3.5 Decylglucoside (PD: ~ 1.4) 2.5 sodium lauroyl 3.0 cocoamidopropyl 3.0 Cationic Polymer (Polyquaternium-16) 0.2 sucrose 0.3 sodium benzoate 0.6 citric acid 0.5 Perfume 0.5 water ad 100.0

This Shampoo was similar in its properties to shampoos Examples 1 and 2.
