Abstract: An aqueous deformation-detecting brightener composition that can easily detect deformation such as unevenness on the surface of a car body by forming a liquid thin film having low foaming property and excellent glossiness is provided by dissolving a glycol ether compound expressed by the following formula (I) and a surfactant in water R1—O—(AO)m—R2  (I) where “R1” represents an alkyl group having 1 to 9 carbon atoms, an alkenyl group having 1 to 9 carbon atoms, an alkylphenyl group having 1 to 9 carbon atoms, or a functional group expressed by the following general formula (II), “A” represents an alkylene group having 2 to 4 carbon atoms, “m” represents an average adduct molar number of alkylene oxide, a number of 1 to 20, in which the same alkylene oxide may be added alone, or a mixture of two or more types of alkylene oxide may be added, and “R2” represents an alkyl group having 1 to 9 carbon atoms, an alkenyl group having 1 to 9

Abstract: A softener composition comprises a mixture of (A) a mono(long-chain) quaternary ammonium salt such as monotallowalkyl trimethyl ammonium chloride, (B) a di(long-chain) quaternary ammonium salt such as ditallowalkyl dimethyl ammonium chloride and (C) a tri(long-chain) quaternary ammonium salt such as tritallowalkyl monomethyl ammonium chloride), the weight ratio of the components (A):(B):(C) falling within the range of from 2 to 30: 96 to 50: 2 to 20, and iodine value of the mixture being in the range of 35 to 100; and (D) a polyoxyethylene adducted nonionic surfactant such as polyoxyethylene octylphenyl ether (P=40). The softener composition improves the softness of natural fibers without impairing the water absorption properties thereof. It also improves the softness of chemical fibers and gives them excellent antistatic property.

Abstract: This invention provides a highly concentrated aqueous softener composition which has improved viscosity characteristics and an excellent long-term storability. The softener composition comprises 7 to 50% by weight of cationic softening agent, 0.05 to 10% by weight of alkylene oxide adducted nonionic surfactant having at least one unsaturated bond in its molecule, 0.005 to 5% by weight of inorganic electrolyte, and the balance of water.
