[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to shampoos for hair styling and preparations for washing the body. After washing with shampoos, showers and bath preparations based on synthetic anionic surfactants, the hair is often in a cosmetically unsatisfactory condition. When wet, combing the hair is difficult and feels dull. After drying, washed hair tends to pick up static electricity, resulting in the well-known "flutter" of freshly washed hair. Moreover, freshly washed hair often has a lackluster appearance. For these reasons, it is known to apply conditioning formulations to the hair after washing or shampooing. The formulation in these cases is most often a rinse or cream-like lotion containing a cationically active surfactant.
It is also known to add certain substances to conventional shampoos to obtain certain conditioning effects during hair washing. Substances of this type are, for example, water-soluble proteins or protein modification products, polycationic polymers, such as aminopolycarbamide resins of the type described in DE-OS No. 21 50 899, US-PS No.
3816616, or polycationic guar derivatives of the type described in US-PS No. 4292212. Many other water-soluble polymers containing cationic or quaternary ammonium groups have been proposed for this purpose. One drawback common to all known hair conditioning additives is that their effectiveness is at least partially diminished when used in anionic hair washing formulations. Products with particularly strong effects often exhibit excessive adsorption to the hair, thus impairing the elasticity, elasticity and shape of dry hair. It is therefore an object of the present invention to make it possible, by the presence of suitable hair restoration additives, to make the hair easier when wet and also to improve the dry hair in particular its elasticity, elasticity, shine and appearance. The object of the present invention is to provide shampoo formulations based on known highly lathering anionic cleansing actives which retain satisfactory cosmetic properties including: The hair-protecting properties of shampoos based on anionic cleansing active substances are achieved by adding to the shampoo a combination of polycationic guar derivatives, curable cationic polycondensation products, hydrophilic fatty acid esters and water-soluble polyvinylpyrrolidone. It has now been discovered that improvements can be made particularly effectively by Accordingly, the present invention provides an anionic detersive active substance; and from 0.1 to 4% by weight of 3-(trimethylamino)-
2-hydroxypropyl guachloride, 0.5 to 5% by weight of a water-soluble polyamine containing reactive amio groups and polyalkylene oxide groups and epichlorohydrin or more than one epoxide group and/or halohydrin group in the molecule 1 to 4% by weight of ethylene oxide adducts of glycerin and 4 to 20 mol of ethylene oxide and 1 to 2 mol of C ₈ -C ₁₈ esterification products with fatty acids, from 0.1 to 1% by weight, with an average molecular weight of at least
10,000 polyvinylpyrrolidone;
This invention relates to a hair conditioning shampoo based on an aqueous solution of. 3-(Trimethylamino)-2-hydroxypropyl guar chloride is a cationic guar derivative known from US-PS No. 3589978. The products described there contain as basic units two mannose units linked by one glucosidic bond and one galactose unit linked to one of the hydroxyl groups of this mannose unit. On average, each hexose ring carries three free hydroxyl groups. These free hydroxyl groups react with reactive quaternary ammonium compounds to give cationic polymers. The cationic polymer used in the shampoo according to the invention is commercially available under the name " ^Cosmedea® -Guar C261". Readily water-soluble curable polycondensation products of water-soluble polyamines containing reactive amino groups and polyalkylene oxide groups with epichlorohydrin or compounds containing more than one epoxide and/or halohydrin group in the molecule are DE−PSNo.

Hair conditioning shampoos with the compositions according to the invention are distinguished by an unexpectedly significant improvement in the conditioning properties of hair washed with them. For example, the so-called wet combability of the shampoo for hair conditioning according to the present invention is considerably improved compared to a shampoo containing only one of the conditioning ingredients, such as Cosmediagua ^(R) C261. . This is all the more surprising since the other essential ingredients have little or no effect on wet hair combing properties.
A similar surprising synergistic effect can be observed when considering various factors: gloss, feel, and antistatic properties, the so-called "conditioning effect." The feel (elasticity) and shine of dry hair are improved by the shampoo according to the invention to a greater extent than with conventional shampoos which contain, for example, only one of the ingredients required in the case according to the invention. Finally, the tendency of the hair to develop static electricity after drying is considerably reduced by using the conditioning shampoo according to the invention; the hair has a reduced tendency to flutter, can be combed more easily, and its shape is kept longer. The hair cosmetic effects obtained with the hair conditioning shampoo according to the invention are demonstrated in the following examples by comparison with conventional shampoos. Examples Shampoo formulations according to the invention (No. 1 to No.

Kosmetika, No. 12/1977” 325 pages, 2nd and 3rd
It is described in the column. Standardized hair tresses were used that had been previously damaged by bleaching and permanent waving under constant conditions. The tresses were washed in hand-warm water with the shampoo shown in Table 1 and rinsed with clear water. To minimize errors, hair combing resistance was measured 15 times for each shampoo tested and the average value calculated. The average hair combing resistance value is expressed as a percentage of the white test value. White test values were determined after shampooing with an aqueous solution containing 10% by weight of sodium lauryl ether diethenoxy sulfate and rinsing with clear water.

The test was conducted by a trained cosmetologist. One-sided tests were used to compare two hair treatment formulations, or one hair treatment formulation and one standard product, on experimental subjects. In these tests, hair shampoo No. 1 according to the invention was used as standard. The comparison scores shown in Table 2 are a measure of the degree to which hair shampoos No. 4 to No. 10 differ from the evaluation of shampoo No. 1. Procedure and Evaluation The hair of the experimental subjects was wetted and parted down the middle. The standard shampoo was applied to the left half of the head of the five test subjects and the comparison shampoo was applied to the right half in equal amounts of 5 g in each case (before washing). other 5
In the case of human test subjects, the other half of their heads were treated with the same product. Wash both sides in the same way with shampoo and rinse with water. For this main wash, Shampoo was again applied in an amount of 2.5 g to the same side of the head, rubbed in to form a lather and rinsed out thoroughly with clear water. During and after washing, the criteria listed in Table 2 below were evaluated by the beautician on each of the two sides separately. Evaluation is based on points (1 = ∧ excellent, 2 = ∧
Good, 3=∧fair, 4=∧bad). From the scores given for the 10 experimental subjects, an average value was calculated for the same product.
The average value for the standard product was subtracted from the average value for the comparative product. The pairwise differences thus obtained in the mean values of the ratings for the 10 experimental subjects are shown in Table 2 below. Results: All comparative shampoos were judged to be inferior in their hair cosmetic properties to the standard shampoo (shampoo No. 1 according to the invention).
