专利号:US-10941231-B2 优先权日:2015-10-02 标 题 :Method for the synthesis of acrylic (co)polymers from oligomers of acrylic acid 发明人:SUAU JEAN-MARC; CHAMPAGNE CLEMENTINE 权利人:ARKEMA FRANCE 摘要:The present invention relates to the synthesis of an associative acrylic (co)polymer by aqueous emulsion radical polymerization. The (co)polymer contains at least one oligomer of acrylic acid represented by the formula (I): n nwhere n is an integer ranging from 1 to 10. The oligomer is prepared from acrylic acid at a temperature of between 50° C. and 200° C. in the presence of a basic or acid catalyst, water, and polymerization inhibitors. The present invention also relates to the associative acrylic (co)polymer obtained from the method and also to the use of this (co)polymer as a thickener in various formulations.
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.
