The aqueous ready-to-apply composition for permanent waving of hair has a pH of 4 to 8.5 and from 3 to 28% by weight of at least one N-alkylmercaptoacetamide of formula (I):

Agent and method for permanent shaping of hair and method for the production of N-alkylmercaptoacetamides

The composition for permanent shaping of hair contains, as keratin-reducing agent, a compound of the formula (I): ##STR1## or a salt thereof, wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represent, independently of each other, H, a straight or branched chain alkyl or hydroxy alkyl group, with 1 to 3 carbon atoms or a carboxyl group, with the proviso that at least one of the R.sub.1, R.sub.2, R.sub.3 and R.sub.4 groups is not H, n and m are whole numbers from 1 to 3 and X is a bivalent group --O--, --CR.sub.5 R.sub.6 -- or --NR.sub.7 --, in which R.sub.5, R.sub.6 and R.sub.7 are each, independently of each other, H or straight chain or branched chain alkyl groups or hydroxyalkyl groups with 1 to 3 carbon atoms or carboxyl groups. New mercaptoacetamide compounds and methods of making them are also described. The composition for permanent shaping provides a safe and uniform shaping of hair without allergic and sensitizing reactions; it has a skin and hair safe pH range of 6.5 to 9.5.

Skin treating composition on the basis of compatible carrier and additional compositions with a content of a defined tetrahydro-1,3-thiazine-2,4-dion derivatives as active ingredients for thickening the epidermis. The skin treating compositions are applied 1-2 times daily onto the skin for about 3 to 4 weeks. Due to the thickening of the epidermis they cause a reinforcement of the skin, in particular against sun rays, cold and the contact with noxious environmental substances of all kinds. Moreover, the skin treating compositions are suitable for a prophylactic fighting of the so-called old age skin. An object of the invention are novel tetrahydro-1,3-thiazine-2,4-dion derivative which are active in the aforementioned manner having the formula ##STR1## wherein R denotes H, alkyl, aryl, arylalkyl has substituted arylalkyl or substituted aryl in the aryl portion, R.sup.2 =H is aryl or substituted aryl, R.sup.b =H, denotes aryl or substituted aryl and R.sup.3 =H, represents alkyl or aryl, provided that R.sup.a, R.sup.b and R.sup.c only simultaneously denote H when R denotes a substituted arylalkyl in the aryl portion and R denotes H, but only if R.sup.a =HR.sup.b =aryl and R.sup.c constitute=H.

Skin treating composition on the basis of compatible carrier and additional compositions with a content of a defined tetrahydro-1,3-thiazine-2,4-dion derivatives as active ingredients for thickening the epidermis. The skin treating compositions are applied 1-2 times daily onto the skin for about 3 to 4 weeks. Due to the thickening of the epidermis they cause a reinforcmenet of the skin, in particular against sun rays, cold and the contact with noxious environmental substances of all kinds. Moreover, the skin treating compositions are suitable for a proplylactic fighting of the so-called old age skin. An object of the invention are novel tetrahydro-1,3-thiazine-2,4-dion derivative which are active in the aforementioned manner having the formula ##STR1## wherein R denotes H, alkyl, aryl, arylalkyl has substituted arylalkyl or substituted aryl in the aryl portion, R.sup.a =H is aryl or substituted aryl, R.sup.b =H, denotes aryl or substituted aryl and R.sup.c -H, represents alkyl or aryl, provided that R.sup.a, R.sup.b and R.sup.c only simultaneously denote H when R denotes a substituted arylalkyl in the aryl portion and R denotes H, but only if R.sup.a =HR.sup.b =aryl and R.sup.c constitute=H.

New 3-carbamoyl- and 3-thiocarbamoyl-tetrahydro-1,3-thiazine-2-thiones are disclosed as skin treatment compositions based upon physiologically-compatible carriers and a content of these compounds as active substance for increasing the skin protection, in particular against sun radiation and contact with environmental substances of all types. The skin treatment compositions are also suitable for prophylactic control of so-called aging skin. The compositions are applied to the skin one or two times daily for about 3-4 weeks.
