Abstract: A stabilizer composition having low volatility and high efficiency comprising: (i.) 25.000% to 99.997% by weight of at least one dimethyltin compound of formula (CH3)2Sn(S(CH2)mCOOR1)2 wherein R1 is a linear, branched or cyclic C10-C20 alkyl group and m is 1 or 2, optionally containing unsaturations in the form of double or triple bonds; (ii.) 0.001% to 50.000% by weight of at least one mono-methyltin compound of formula CH3Sn(S(CH2)nCOOR2)3 wherein R2 is a linear, branched or cyclic C10-C20 alkyl group and n is 1 or 2, optionally containing unsaturations in the form of double or triple bonds; (iii.) 0.001% to 10.000% by weight of at least one tri-methyltin compound of formula (CH3)3Sn(S(CH2)pCOOR3) wherein R3 is a linear, branched or cyclic C10-C20 alkyl group and p is 1 or 2, optionally containing unsaturations in the form of double or triple bonds; and (iv.) 0.001% to 15.

Abstract: Fatty alcohol containing admixed therewith a small amount on the order of up to 1.0 wt. % of hypophosphorous acid, exhibits markedly reduced oxidation and oxidation-related deterioration such as discoloration and other side effects. This discovery is particularly useful when the fatty alcohol is subjected to reactions such as esterification under conditions which could cause or accelerate undesired oxidation.
