  • Patent number: 4883652
    Abstract: 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.
