专利号:US-2023111600-A1 优先权日:2019-12-17 标题 :Polymeric fatty acid compounds for the treatment of fibrous amino acid-based substrates, especially hair 发明人:WAGNER ROLAND; STREICHER KATHARINA; ROHMANN LAURA; WENSKE CHRISTIAN; HAVELI SHRUTISAGAR DATTATRAYA 权利人:MOMENTIVE PERFORMANCE MAT GMBH 摘要:The present invention is directed at mono-, di- or polyquaternary ammonium compounds of the formula (I) wherein x is 1 to 50, and F can be the same or different and is represented by the general formula (II) wherein at least one of the optionally substituted and optionally functional-group-containing hydrocarbon radicals R 1 , R 2 , R 3 , R 4 or R 5 contains at least one estolide moiety comprising two or more ester or amide moieties. The invention also relates to a process for the synthesis of such compounds, the use of the compounds in cosmetic formulations for skin and hair care, cosmetic compositions for the treatment of fibers, and compositions containing one or more of the compounds for the treatment of hair.
专利号:US-6174956-B1 优先权日:1995-06-02 标题 :Synthesis of condensation polymers in densified fluids 发明人:KERSCHNER JUDITH LYNNE; JURELLER SHARON HARRIOTT; THOMAIDES JOHN SOCRATES; HUMPHREYS ROBERT WILLIAM; IOVINE CARMINE PHILLIP 权利人:NAT STARCH CHEM INVEST 摘要:A polyurethane polymer and method of preparing it is described. The process requires the combination of a soluble polyol with a di- or polyisocyanate under densified fluid conditions. The process to prepare a waterborne polyurethane involves the utilization of a polyol containing ionic or latent ionic groups which must undergo preneutralization before combining with the di- or polyisocyanate under densified fluid conditions. The resulting polyurethane is substantially free of an organic solvent.
专利号:US-5662898-A 优先权日:1990-08-20 标 题 :Genes for the synthesis of antipathogenic substances 发明人:LIGON JAMES M; HILL DWIGHT STEVEN; LAM STEPHEN TING; HAMMER PHILIP E 权利人:CIBA GEIGY CORP 摘要:The present invention is directed to the production of an antipathogenic substance (APS) in a host via recombinant expression of the polypeptides needed to biologically synthesize the APS. Genes encoding polypeptides necessary to produce particular antipathogenic substances are provided, along with methods for identifying and isolating genes needed to recombinantly biosynthesize any desired APS. The cloned genes may be transformed and expressed in a desired host organisms to produce the APS according to the invention for a variety of purposes, including protecting the host from a pathogen, developing the host as a biocontrol agent, and producing large, uniform amounts of the APS.

专利号:US-7312251-B2 优先权日:1999-04-26 标题 :Synthesis of stable solutions of rare earth tris (organophosphate) in hydrocarbon solvents 发明人:YUNLU KENAN; HE MIN 权利人:RHODIA RARE EARTHS INC 摘要:Stable rare earth tris (organophosphate) solutions comprise a rare earth tris (organophosphate) and a hydrocarbon solvent. From about 2% to about 10% rare earth element, preferably from about 3% to about 8%, is present in the solutions. The rare earth tris (organophosphate) solutions are stable from precipitation of the rare earth tris (organophosphate) for at least about fifteen (15) days, preferably for at least about twenty (20) days and most preferably at least about thirty (30) days. A process for preparing these solutions is described herein. A stabilizing additive, acid, glycol or mixtures thereof, is utilized to inhibit precipitation. The molar ratios of free acid, glycol and/or water to the rare earth element are controlled to inhibit precipitation.
