摘要:
The present invention is directed at organic ammonium salts comprising an organic ammonium-group-comprising cation which does not contain an estolide moiety and a carboxylate anion (COO-) group-comprising anion selected from the group consisting of anions containing at least one estolide moiety or carboxylate anions containing at least one internal ester group. The invention is also directed at a process for the production of such organic ammonium salts, the use of such organic ammonium salts in cosmetic formulations for skin and hair care, the use of such organic ammonium salts for the treatment of fibers, the use of the organic ammonium salts for the treatment of hair, at compositions containing such organic ammonium salts, the use of the products of the process for the production of organic ammonium salts in cosmetic formulations for skin care and hair conditioner and hair shampoo, the use of said products for the treatment of fibers, and compositions containing said products for the treatment of hair.

摘要:
The invention relates to a joint method of producing fatty nitriles and/or amines and dialkyl carbonates of formula R1O-CO-OR1 in which R1 comprises from 1 to 4 carbon atoms, starting from an ester of a saturated or unsaturated fatty acid derived from natural oils comprising the following zones: I) a zone for synthesis of a nitrile/amine comprising the following steps: a) optional conversion firstly by hydrolysis of the fatty acid ester derived from an oil of natural origin, to fatty acid simultaneously producing the alcohol R1OH which is recovered and sent to zone III, followed by b) ammoniation with ammonia of the fatty acid resulting from step a) and/or of the fatty acid ester to a nitrile respectively producing an ammonia/water mixture and/or an alcohol/ammonia/water mixture which are sent to zone IV, then by c) hydrogenation of the nitrile resulting from step b), optionally in the presence of ammonia, converting the nitrile to the corresponding amine, II) zone for synthesis of a carbonate of a monoalcohol by reaction of urea with the alcohol R1OH, the reaction of said alcohol with urea also producing ammonia, III) zone for recovery and purification of the alcohol R1OH which is used to supply zone II, IV) zone for recovery of the ammonia from zones I and II in order to be used as a supply for the ammoniation of step b) and optionally the hydrogenation of step c) in zone I.

L'invention vise un procédé conjugué de production de nitriles et/ou d'aminés gras et de dialkylcarbonates de formule R 1 O-CO-OR 1 dans laquelle R 1 comporte de 1 à 4 atomes de carbone, à partir d'un ester d'un acide gras insaturé ou non issu d'huiles naturelles comportant les zones suivantes : I) zone de synthèse d'un nitrile/amine comportant les étapes suivantes : a) transformation optionnelle tout d'abord par hydrolyse de l'ester de l'acide gras issu d'une huile d'origine naturelle, en acide gras produisant simultanément l'alcool R 1 OH qui est récupéré et adressé à la zone III, suivie en b) d'une ammoniation avec de l'ammoniac de l'acide gras issu de l'étape la et/ou de l'ester de l'acide gras en nitrile produisant respectivement un mélange ammoniac/eau et/ou un mélange alcool/ammoniac/eau qui sont envoyés à la zone IV, puis en c) d'une hydrogénation du nitrile issu de l'étape b), éventuellement en présence d'ammoniac, transformant le nitrile en aminé correspondante, II) zone de synthèse d'un carbonate de mono-alcool par réaction de l'urée sur l'alcool R 1 OH, la réaction dudit alcool avec l'urée produisant également de l'ammoniac, III) zone de récupération et de purification de l'alcool R 1 OH qui sert d'alimentation pour la zone II, IV) zone de récupération de l'ammoniac issue des zones I et II pour servir d'alimentation pour l'ammoniation de l'étape b et éventuellement l'hydrogénation de l'étape c dans la zone I.
摘要:
The invention relates to the use of Y terminal groups, wherein Y represents CF 3 (CH 2 ) a S- or CF 3 CF 2 S- or [CF 3 - (CH 2 ) a ] 2 N-, a represents a whole number selected from the range of 0 to 5, as terminal groups in surface-active compounds. The invention also relates to novel compounds and to a method for producing said compounds.
摘要:
The present invention is directed to alkyl allyl amine monomers and their use as a polymerizate in a low VOC hair spray formulation. The hair spray formulation preferably includes a polymerizate of an alkyl allyl amine monomer, preferably an alkyl diallyl amine monomer alone or in combination with other known monomers. The hair spray formulation preferentially satisfies low VOC requirements while maintaining characteristics desired in a hair fixative product.
摘要:
An adhesive or sealant composition comprising a compound of formula (I) provided that at least one of (a) R and R or (b) R and R or (c) R and R includes an electron withdrawing group; and where necessary, a polymerisation initiator. Novel compounds of formula (I) are also described and claimed. Adhesive compositions can be used to bond for example glass and metal surfaces. Certain biocompatible adhesives for medical applications are included.
