摘要： An alkylbiphenyldisulfonate represented by formula: ##STR1## wherein R represents an alkyl group having from 10 to 15 carbon atoms; M represents an alkali metal atom; and m and n each represents 0, 1, or 2, and m+n=2. The alkylbiphenyldisulfonate exhibits excellent solubility in a concentrated aqueous electrolytic solution and, when used in an emulsion polymerization system, provides a polymer having a fine particle size and excellent stability.

摘要： A liquid detergent composition is disclosed, which contains an N-acylaspartic acid or a salt thereof represented by formula (I): ##STR1## wherein R represents an alkyl or alkenyl group having from 7 to 21 carbon atoms; and M.sub.1 and M.sub.2 each represents a hydrogen atom or a cation derived from Na, K, NH.sub.4 or an alkanolamine, and a nitrogen-containing surface active agent selected from the group consisting of an alkylbetaine or alkylamidebetaine represented by formula (II): ##STR2## wherein R.sub.1 represents and alkyl or alkenyl group having from 10 to 22 carbon atoms which may contain an amide linkage in the chain thereof; and R.sub.2 and R.sub.3 each represents an alkyl group having from 1 to 3 carbon atoms, and an imidazoline compound represented by formula (III): ##STR3## wherein R.sub.4 represents an alkyl or alkenyl group having from 4 to 18 carbon atoms; R.sub.5 represents an alkylene group having from 1 to 4 carbon atoms; R.sub.6 represents an alkylene group having from 1 to 4 carbon atoms or a hydroxyl-substituted alkylene group having from 1 to 4 carbon atoms; and M.sub.3 represents a hydrogen atom or a cation derived from Na, K, NH.sub.4 or an alkanolamine. The composition exhibits excellent detergency and foamability while being mild to the skin.

摘要： A liquid detergent composition is disclosed, containing (a) an N-acylaspartic acid or a salt thereof, (b) a tertiary alkylamine oxide and (c) an alkyl ether sulfate, the weight composition of the components (a), (b), and (c) falling within the range indicated by a quadrate formed by four points (90,5,5), (75,20,5), (50,20,30), and (65,5,30) in a triangular coordinate constructed by placing the pure components (a), (b), and (c) at the vertices of a regular triangle. The composition exhibits excellent foamability and detergency while retaining mildness to the skin and substantial fluidity.
