Novel approximatelya,approximatelyc-aminofunctionalized polysiloxanes are useful in cosmetic formulations for skin and hair care, in polishes and as softeners.

摘要

Novel alpha , psi -aminofunctionalized polysiloxanes are claimed. alpha , psi -aminofunctionalized polysiloxanes (I) are of formula (1). C-Z-S-Z-C (1) S = formula (2); R<1> = 1-22C alkyl optionally fluorinated or aryl; n = 0-1000; Z = divalent, branched, linear or cyclic 3-20C hydrocarbon, optionally containing -O-, -NH-, -NR<1>-, -C(O)- or -C(S)- or substituted by OH; C = -N(R<2>)(R<3>) or -N<+>(R<2>)(R<3>)(R<4>); R<2> = formula (3); t = 0-17; M = univalent metal and/or ammonium ion; R<3> = H or R<4>; R<4> = linear, cyclic or branched 1-1000 C hydrocarbon, optionally containing -O-, -NH-, -NR<1>-, -C(O)- or -C(S)- or substituted by OH; R<3> and R<4> = A-(CH2CH2CH2O)q-(CH2CH(CH3)O)r-R6; Q = 1-200; R = 0-200; A = -CH2C(O)O-, -CH2CH2C(O)O-, -CH2CH2CH2C(O)O- or CH2CH(OH)CH2O-; R<6> = H, 1-20C acetylenic, olefinic or aromatic hydrocarbon optionally containing -O- or -C(O)- and substituted by OH; R<5> = H, NH2 or 1-10C hydrocarbon, optionally containing -NH- and/or -N= and substituted by OH, -COO<->, -C(O)NH2 or NH2 An Independent claim is included for a process for the production of polysiloxanes (I) by alkylation of aminoacids having secondary amine groups with reactive, alkylating siloxane intermediates that are reacted by hydrosilylation of halogenated alkenes, unsaturated halogenated carboxylic acid esters and epoxyfunctionalized alkenes and alkylglycidylethers with alpha , psi -Si-H functionalized siloxanes of formula (4) wherein the carboxyl function of the aminoacid structure is in alkali salt or ester form and the stoichiometric ratio of secondary amines to the alkylating group is 1:1.
