专利号:US-2024082118-A1 优先权日:2021-05-19 标 题:Topical compositions and methods of preparing the same 发明人:ABRAMOVICH SAGI; AVIDOR GAL; LANDA BENZION 权利人:LANDA LABS 2012 LTD 摘要:There is disclosed a composition comprising a water-insoluble thermoplastic compound capable of stimulating collagen synthesis (CSSC), the CSSC having a molecular weight of more than 0.6 kDa and being dispersed in a polar carrier as nano-elements having an average diameter of 200 nm or less and a viscosity of 107 mPa·s or less. The nano-elements of CSSC can be capable of stimulating the synthesis of skin proteins and/or enabling the delivery of active agents upon their application to a surface to be treated therewith. Methods for preparing the compositions and uses thereof are also provided.
专利号:US-2007243147-A1 优先权日:2004-07-24 标 题:Skin and/or Hair Composition Containing Compounds for Increasing The Tanning of Skin 发明人:WOLBER RAINER; TOM DIECK KAREN; SCHERNER CATHRIN; SCHLENZ KATHRIN; KRUSE INGE 权利人:BEIERSDORF AG 摘要:The invention relates to agents that are to be applied to the skin or hair and contain compounds for intensifying tanning of the skin and increasing melanin synthesis in skin or hair. The invention particularly relates to cosmetic or dermatological preparations. Using said preparations results in inducing and intensifying the tanning mechanisms of the skin, intensifying the hair color, and thus also increasing intrinsic protection of the skin or hair.
专利号:US-7618662-B2 优先权日:2004-12-22 标题:Use of natural plant extracts in cosmetic compositions 发明人:HINES MICHELLE D; DUGGAN MICHELE C; BINETTI RALPH R 权利人:AVON PROD INC 摘要:The present invention describes compositions and methods for treating, preventing and improving the appearance of skin, particularly, treating, preventing, ameliorating, reducing and/or eliminating loss of subcutaneous fat in the skin, wherein the compositions include natural plant constituents that stimulate lipid synthesis. The plant extracts are preferably derived from Rhinacanthus nasutus, Humulus scandens, Sesbania grandiflora, Amorphophallus campanulatu, Pouzolzia pentandra , and Piper betel , and any combinations thereof. The compositions are preferably applied to the skin, or are delivered by directed means, to a site in need thereof.
专利号:US-2012237623-A1 优先权日:2009-12-04 标题 :Topical Compositions Containing Derris Scandens Benth and a Method of Treating Skin 发明人:PTCHELINTSEV DMITRI S; LUO XIAOCHUN 权利人:PTCHELINTSEV DMITRI S; LUO XIAOCHUN; AVON PROD INC 摘要:Topical compositions and methods of use to treat symptoms of reduced skin elasticity are provided comprising extracts of a. Derris scandens Benth. plant. These compositions are effective in stimulating LOXL-1, activity, inhibiting calcineurin activity, and stimulating glycosaminoglycan synthesis in skin cells and can thus reduce age-related skin damage and improve appearance of fine lines, wrinkles, skin sagging and other symptoms of skin aging and/or skin damage.
专利号:US-8575106-B2 优先权日:2009-08-31 标题:Cosmetic uses of modified stressed yeast extracts and related compositions 发明人:SANTHANAM UMA; KYROU CHRISTOS D; MAZICH DESIREE; HONG QI; SHAHEEN HUSSAM H 权利人:SANTHANAM UMA; KYROU CHRISTOS D; MAZICH DESIREE; HONG QI; SHAHEEN HUSSAM H; AVON PROD INC 摘要:Cosmetic compositions comprising a metal-complexed peptide fraction of stressed yeast extracts and/or a calcium influx inhibitor are disclosed, as well as methods of using such compositions to impart exfoliating, anti-aging, anti-lipid, anti-inflammatory, and/or lightening benefits to the skin; and/or lightening benefits to the hair. These compositions are believed to have modulatory activity against at least one biochemical pathway implicated in skin aging, inflammation, lipid synthesis, and melanin production.
专利号:US-2007189984-A1 优先权日:2003-09-08 标题:Agents for use on skin and/or hair containing quadruply substituted cyclohexene compounds 发明人:WOLBER RAINER; SCHERNER CATHRIN; TOM DIECK KAREN; SCHLENZ KATHRIN; VIETZKE JENS-PETER 权利人:BEIERSDORF AF 摘要:The invention relates to agents for use on skin or hair, particularly for increasing skin tanning and the synthesis of melanin in skin or hair. The invention contains, in particular, cosmetic or dermatological preparations containing quadruply substituted cyclohexene compounds. The use of the preparations leads to the induction and intensification of the tanning mechanisms of skin, the intensification of hair color and thus also to an intensification of the skin's and hair's intrinsic protection.
