A method for producing a monoalkanol amide comprising the steps of (a) treating an entire amount of fatty acid with a monoalkanol amine in an amount of 0.7 to 0.95 times by mole of the amount of the fatty acid and more than 70% and not more than 90% by weight of the entire amount of the monoalkanol amine to yield a mixture mainly containing a monoalkanol amide and an amido monoester; and (b) treating the mixture obtained in step (a) with the remaining portion of the monoalkanol amine, wherein the molar ratio of the entire amount of the monoalkanol amine to that of the fatty acid is 1.0 to 1.3.

Method for producing monohydroxyalkylamides

A cationic compound is useful for a cleaning agent such as shampooing and defined by the formula (I): ##STR1## in which R1 is straight or branched and an alkyl having 7 to 15 carbon atoms or an alkenyl having 7 to 15 carbon atoms; R2, R3 and R4, independently of one another, are an alkyl having 1 to 3 carbon atoms; G is hydrogen atom, an alkyl having 1 to 3 carbon atoms or a hydroxyalkyl having 1 to 3 carbon atoms, E is hydrogen atom, an alkyl having 1 to 3 carbon atoms, a hydroxyalkyl having 1 to 3 carbon atoms or an ammonium group having the formula (II): ##STR2## Y being hydrogen atom or hydroxy, A being hydroxy, a halogen atom or an alkylsulfate having 1 to 4 carbon atoms, m being 2 or 3, n being zero or an integer of 1 to 5, provided that (1) when G is an alkyl or a hydroxyalkyl, E is neither an alkyl nor a hydroxyalkyl, (2) when n is 1, Y is hydrogen atom or hydroxy and when n is zero, 2, 3, 4 or 5, Y is hydrogen atom and (3) G and E cannot both be hydrogen.

Mild cationic surfactants having good foaming conditioning properties

The polycationic compound having the formula (I) is useful for an organic peracid precursor. A bleach composition comprises the polycationic compound and a peroxide. ##STR1## in which X is a cation, Y is an alkylene, Z is a specific group containing carbonyl group and A is an anionic group.
