Since June 1981, Mink Oil Pure has been routinely examined within the scope of Epicutaneous tests and compatibility tests as well as in application to normal test persons and patients with sensitive skin. It was determined that Mink Oil revealed no incompatibility in any of the aforementioned test procedures and applications. Even patients displaying extreme sensitivity toward basic ingredients contained in ointments used for cosmetic purposes and in dermatological therapy showed no reaction to Mink Oil Pure. In further tests, the skin reaction in the areas to which Mink Oil had been applied was tested with regard to intensive exposure to ultraviolet B and A. An undesired phototoxic reaction was not determined. These tests were conducted routinely, and the analysis of the Mink Oil revealed no substances capable of a phototoxic reaction.




Examinations of the skin surface fat after application of Mink Oil Pure revealed that Mink Oil Pure penetrates the deeper layers of skin. Within ½ hour, Mink Oil diffuses into the lower layers of the skin, thus preventing an undesired, long lasting greasing effect starting from the skin surface. Mink Oil Pure is undoubtedly a substance patients like to use for skin care. The cosmetic characteristics of Mink Oil Pure skin care have an effect on both dry and normal skin.

Of particular value from the dermatological viewpoint is the statement that an incompatibility reaction of skin irritation was not revealed, even under particular stress in a clinical experimental sense as well as under normal exposure. This statement pertains to the aforementioned pure mink oil, which contained no additives.

A total of 238 patients of a dermatology clinic were tested in area of unchanged skin. In addition, mink oil was used for the after-treatment of exsiccated skin following recent dermatosi whereby a total of 18 patients showing an incompatibility with Lanolin tolerated Mink Oil Pure without any reaction. The same was found with 4 patients displaying an incompatibility with Lanette.

Thus, Mink Oil Pure appears to be a raw material which is very well tolerated by the human skin. Mink Oil Pure penetrates into the lower layers of skin and complements the fat content of dry skin, no undesired subsequent fatting is found in normal skin, and no unpleasant effects of additional fatting were determined in the case of so-called seborrheic skin which is characterized by an increased secretion and discharge of sebum, when treated with Mink Oil Pure.
