The catalyst system will comprise (1) a composite of oxides of copper, zinc and aluminum or chromium, and (2) an alumino-silicate which may be either in crystalline or amorphous form.
专利号:US-6150403-A 优先权日:1997-10-14 标 题 :Topical compositions for regulating the oily/shiny appearance of skin 发明人:BIEDERMANN KIMBERLY A; SCHUBERT HARRY L; PARRAN JR JOHN J 权利人:PROCTER & GAMBLE 摘要:The present invention relates to methods for inhibiting sebaceous gland activity in mammalian skin comprising administration of a topical composition comprising dehydroacetic acid or pharmaceutically acceptable salts thereof, and a dermatologically-acceptable carrier. The present invention also relates to methods and topical compositions further comprising agents which regulate the oily and/or shiny appearance of skin, and agents which treat acne and related skin disorders in mammalian skin and scalp. Methods of reducing sebum synthesis with the use of dehydroacetic acid, methods of regulating the oily and/or shiny appearance of skin, and methods of treating acne and other skin disorders are also encompassed by the present invention.
专利号:US-7250529-B2 优先权日:2004-09-17 标题:Synthesis process for 2-(3-hydroxy-1-adamantyl)-2-oxoacetic acid 发明人:WILLIAMS ERIC L 权利人:ALBEMARLE CORP 摘要:A highly advantageous process for the preparation of 2-(3-hydroxy-1-adamantyl)-2-oxoacetic acid or a salt thereof is described. The process comprises subjecting 1-acetyl 3-hydroxyadamantane to liquid phase oxidation with permanganate to produce 2-(3-hydroxy-1-adamantyl)-2-oxoacetic acid or a salt thereof, with acidification to form the free acid when appropriate.
