 consists, in which R 'is hydrogen or a lower alkyl radical with at most 6 carbon atoms, R is a lower alkyl radical and one of the radicals R and Ru is hydrogen or a lower alkyl radical, while the other is a hydrophobic aliphatic radical with 8-24 carbon atoms and where the solution this salt contains in an amount of 0.2 to 0.75 mol per liter of solution.



   The acid component of this salt can e.g. B. consist of a weak organic acid such as lactic acid or citric acid.



   Due to their chemical constitution, the compounds according to the above formula have surface-active properties and a moderate reducing effect on hair keratin. This re-

   Ductile effect, which would not be sufficient for permanent waving in the usual sense, is, however, particularly suitable for so-called laying hair.



   The relatively few reduced -SS bonds that are reduced when these surface-active reducing agents are used can be restored by the sole action of atmospheric oxygen in the course of the usual drying process in a stream of air under the hood, without using an oxidizing solution, as is the case with conventional permanent waving needs to arrive.



   The compounds of the above formula also have the properties of a cationic, foaming wetting agent which exerts a cleaning effect on the hair and whose aliphatic chain adheres to the hair and gives the cleaned hair shine and softness.



   When using the hair care composition according to the invention, the procedure can therefore be followed in the same way as for conventional shampooing, as is normally used before the purely mechanical laying of the hair; In this way, at least at the beginning, any additional dilution with water can be avoided, after which it is rinsed, laid and dried in the usual way.



     Example 1: The following solution is produced:
 EMI2.1
 
<tb>
<tb> Mercapto-N-Iauiyl-N- <SEP> (2-diethyl- <SEP>
<tb> aminoethyl) acetamide lactate <SEP> 22 <SEP> g
<tb> lactic acid <SEP> 2.2 <SEP> g
<tb> water <SEP> to <SEP> 100 <SEP> cms.
<tb>
 



   This solution is applied directly to the hair as with normal shampooing. You can make them foam by lightly rubbing them, rinsing them and pressing them out with a towel. If necessary, this process is repeated a second time, again rinsing and overdrying. The hair is then laid in the usual way (with the help of your own curlers, clamps, etc., or simply wrapped around your fingers and pinned) and dried in hot air under the hood or in the surrounding air, whereby the hair is restored to its natural elasticity through oxidation becomes.



   In this way, a hairstyle is obtained whose durability is considerably greater than if the hair were simply moistened with water in the usual way before laying.



   Example 2: Prepare the following solution:
 EMI2.2
 
<tb>
<tb> Mercapto-N- <SEP> (2-methyl-2-laurylaminoethyl) -acetamide-lactate <SEP> 24 <SEP> g
<tb> lactic acid <SEP> S, <SEP> 4g
<tb> water <SEP> to <SEP> 100 <SEP> cm8.
<tb>
 



   The solution is applied as in the previous example.



   The characteristics of the hairstyle thus obtained. are far superior to those of a hairstyle laid in the usual way.

 

Claims (1)

PATENT CLAIM: Agent for laying hair without prior permanent waving, characterized in that it is made from an aqueous solution of a salt of an acid harmless to skin and hair and a compound of the general formula EMI2.3 consists, in which R 'is hydrogen or a lower alkyl radical with at most 6 carbon atoms, R "is a lower alkyl radical and one of the radicals R and R" is hydrogen or a lower alkyl radical, while the other is a hydrophobic aliphatic radical with 8-24 carbon atoms, and wherein the solution contains this salt in an amount of 0.2 to 0.75 moles per liter of solution.
