  • Patent number: 4865840
    Abstract: Topical application of selenoamino acids, such as L-selenomethionine, leads to significantly enhanced levels of selenium in the skin, and also to enhanced levels of selenium in the plasma and liver without toxicity. These enhanced levels of selenium provide protection from ultraviolet radiation-induced skin damage, and significantly reduce the incidence of skin cancers following ultraviolet light exposure.

The immobilized enzymes are lipolytic lipases, proteolytic proteases and enzymes for the breakdown of sugar oligomers from glucoproteins in the skin exudates. The enzymes may be present individually or in any desired combination. The enzymes are immobilized in known manners by chemical and or physical means and are released from immobilization upon application to the skin.

  • Patent number: 4216201
    Abstract: A cosmetic emulsion base for stable, appealing cosmetic creams and lotions having excellent skin moisturizing properties is provided in the form of a water in oil (W/O) emulsion wherein 60 to 80% by weight of water is dispersed and stabilized in an external oil phase comprising 15 to 25% straight chain hydrocarbons of desired oiliness and consistency and including branched chain hydrocarbon oil components to aid skin penetration, a mixture of emulsifier components comprising about 5 to 10% of the compositions and consisting essentially of 1 esters of fatty acids containing twelve to eighteen carbon atoms and polyhydric alcohols containing three to ten carbon atoms and lesser amounts of a di- or tri-valent metallic soap. As applied to the skin the W/O emulsions enhance moisture penetration of the skin while minimizing loss by evaporation, and may provide excellent carriers of cosmetic covering and coloring agents in amounts up to about 10% by weight of the composition.
