    • The invention relates to new cationic surfactants based on quaternary ammonium compounds corresponding to the general formulaR.sup.1 -CHOH-CHR.sup.2 -N.sup.+ R.sup.3 R.sup.4 R.sup.5 R.sup.6 CO.sub.2.sup.- (1)whereinR.sup.1 is a linear or branched alkyl residue having from 1 to 22 carbon atoms;R.sup.2 is hydrogen or a linear or branched alkyl residue having from 1 to 21 carbon atoms, the total number of carbon atoms of the substituents R.sup.1 and R.sup.2 being in the range of from 8 to 22;R.sup.3 and R.sup.4 each represent methyl, ethyl, 2-hydroxyethyl or 2-hydroxypropyl;R.sup.5 represents an alkyl residue having from 4 to 6 carbon atoms or a phenalkyl residue having from 1 to 3 carbon atoms in the alkyl residue; andR.sup.6 represents a linear or branched alkyl residue having from 4 to 15 carbon atoms.The cationic surfactants have particular utility in cleaning agents.
    • 本发明涉及基于对应于通式R1-CHOH-CHR2-N + R3R4R5R6CO2-(1)的季铵化合物的新型阳离子表面活性剂,其中R1是具有1至22个碳原子的直链或支链烷基; R2是氢或具有1至21个碳原子的直链或支链烷基,取代基R 1和R 2的碳原子总数在8至22的范围内; R3和R4各自表示甲基,乙基,2-羟乙基或2-羟丙基; R5代表具有4至6个碳原子的烷基残基或在烷基残基中具有1至3个碳原子的苯烷基残基; 并且R 6表示具有4至15个碳原子的直链或支链烷基。 阳离子表面活性剂在清洁剂中具有特别的用途。
