The present invention provides a softener composition which contains a softening base having an excellent softening effect and satisfactory biodegradability. That is, the present invention provides the softener composition which comprises (A) a nonionic compound which has at least one Calkyl or alkenyl group and an amide bond but contains no dissociative group of amino or carboxyl group; and (B) at least one member selected among (B-&#x3b1;) cationic or ampholytic surfactants having one Calkyl or alkenyl group or one optionally substituted aryl group and (B-&#x3b2;) amino compounds having at least one Calkyl or alkenyl group and salts of the compounds.

Softener composition

The present invention relates to a surfactant composition containing a composition containing a diol derivative (I) and a surfactant: wherein Ris an alkyl or alkenyl group having 4 to 22 carbons, Ris an alkyl or alkenyl group having 1 to 18 carbon atoms and one of Rand Ris a straight-chain or branched alkyl or alkenyl group having 4 to 22 carbon atoms and derived from Rand the other is a hydrogen atom.

Surfactant composition

The present invention provides a thickener which is superior in compounding stability and has high thickening action and a surfactant composition containing the thickener. The present invention relates to a thickener comprising a fatty acid amide ether compound (1) and to a surfactant composition comprising this thickener and at least one surfactant. Namely, the present invention relates to a method of increasing the viscosity of a surfactant by using this thickener.wherein Rrepresents a straight-chain or branched alkyl or alkenyl group which has 5 to 21 carbon atoms and may be substituted with at least one hydroxyl group, Rrepresents a straight-chain or branched alkyl group having 1 to 12 carbon atoms and Rrepresents an alkylene group having 2 to 12 carbon atoms.

Thickener

A thickener which is superior in handling characteristics and blending stability and has a high thickening action is provided, comprising a fatty acid alkanolamide represented by the general formula (1) and a surfactant composition comprising the thickener and at least one surfactant:wherein Rrepresents a straight-chain or branched alkyl or alkenyl group having 5 to 21 carbon atoms which may be substituted with at least one hydroxy group, Rand Rindependently represent an alkyl group having 1 to 2 carbon atoms, AO represents an oxyalkylene group having 2 to 4 carbon atoms and n denotes a number of 0 to 10 in average.

Softening finish composition

The present invention provides a softener composition which contains a softening base having an excellent softening effect and satisfactory biodegradability. That is, the present invention provides the softener composition that has (A) a nonionic compound which has at least one C -C alkyl or alkenyl group and an amide bond but contains no dissociative group of amino or carboxyl group; and (B) at least one member selected among (B-&agr;) cationic or ampholytic surfactants having one C -C alkyl or alkenyl group or one optionally substituted aryl group and (B-&bgr;) amino compounds, having at least one C -C alkyl or alkenyl group and salts of the compunds.
