Abstract: A cleanser composition comprising a phosphate type surfactant and an amide ether carboxylic acid as the essential components. This cleanser composition is lowly irritant to the skin etc., and excellent in lathering property, gives creamy foam in quality, and can give an excellent feeling to the skin cleansed even when it is used in hard water.

Abstract: Described is a detergent composition comprising (A) a sulfate ester surfactant, (B) at least one surfactant selected from amphoteric surfactants, amine oxide surfactants, alkanol amide surfactants and amide amino-acid surfactants, (C) a cationic bactericide and (D) a metal chelating agent, the weight ratio of said (A) to (B) being 1-50 and the content of said (C) being 0.2 wt. % to 5 wt. %.The detergent composition according to the present invention has excellent detergency, foamability and foam durability and at the same time, has high bactericidal effects because it can be mixed stably with a cationic bactericide.

Abstract: A germicidal-disinfectant detergent composition comprising (a) a cationic germicide, (b) a metal chelating agent and (c) at least one surfactant selected from anionic surfactants, nonionic surfactants and amphoteric surfactants is described. Excellent detergency and germicidal action are provided.

Abstract: A cleanser composition comprising an alkylphosphate type surfactant and an ether acetic acid type surfactant represented by the following formula (3) :R.sup.4 --O--(CH.sub.2 CH.sub.2 O).sub.p --CH.sub.2 CO.sub.2 X.sup.3(3)wherein R.sup.4 represents an alkyl or alkenyl group having 8 to 18 carbon atoms, X.sup.3 represents a hydrogen atom, an alkali metal atom, a triethanolammonium group or an ammonium group, and p represents a number of 3 to 15.The cleanser composition is excellent in cleansing property of the skin and hair, and low irritant. Further, even when the cleanser composition contains a phosphate salt in a concentration of 30% by weight or above, the viscosity of the composition is not increased and the incorporation of a third component thereinto is easy.

Abstract: A thermal decomposition apparatus for plastics wherein plastics are melted and thermally decomposed, and the resulting decomposition gas is cooled for condensation and recovered in the form of a thermal decomposition oil. The apparatus comprises a thermal decomposition reactor for melting and thermally decomposing the plastics therein, an extraneous matter discharge duct having one end opened in a melt of plastics within the reactor, an extraneous matter collecting container connected to the other end of the discharge duct, and an aspirator for aspirating extraneous matter within the reactor together with the melt through the discharge duct into the container.
