The organophilic clay comprises a smectite-type clay ion exchanged with quaternary ammonium ions, where at least 75 mol-% of said quaternary ammonium ions are bis-(2-hydroxypropyl)-dimethylammonium fatty acid esters and at least 90 % of the fatty acid moieties of the bis-(2-hydroxypropyl)-dimethylammonium fatty acid esters have a structure RC(O) with group R being a linear alkyl or alkenyl group containing from 9 to 21 carbon atoms. The organophilic clay is useful for thickening oil based compositions, in particular drilling fluids for drilling oil or gas wells, comprising an oil phase.
A fabric softener active composition, comprising as component A at least 50% by weight of a bis-(2-hydroxypropyl)-dimethylammonium methylsulphate fatty acid ester having a molar ratio of fatty acid moieties to amine moieties of from 1.5 to 1.99, an average chain length of the fatty acid moieties of from 16 to 18 carbon atoms and an iodine value of the fatty acid moieties, calculated for the free fatty acid, of from 0.5 to 50, and as component B a (2-hydroxypropyl)-(1-methyl-2-hydroxyethyl)-dimethylammonium methylsulphate fatty acid ester having the same fatty acid moieties as component A, and wherein the molar ratio of component B to component A is from 0.05 to 0.20.
一种织物柔软剂活性组合物,作为 A 组分,包含至少 50%(按重量计)的双-(2-羟基丙基)-二甲基甲基硫酸铵脂肪酸酯,其脂肪酸分子与胺分子的摩尔比为 1.5 至 1.99,脂肪酸分子的平均链长为 16 至 18 个碳原子,以游离脂肪酸计算的脂肪酸分子的碘值为 0.5 至 50,作为 B 组分,包含具有相同脂肪酸分子的(2-羟基丙基)-(1-甲基-2-羟乙基)-二甲基甲基硫酸铵脂肪酸酯。5至50,而作为组分B的(2-羟基丙基)-(1-甲基-2-羟乙基)-二甲基甲基硫酸铵脂肪酸酯具有与组分A相同的脂肪酸分子,其中组分B与组分A的摩尔比为0.05至0.20。
