Abstract:
PURPOSE: To obtain a high density granular detergent composition for clothing, etc., having little effect on the environment and containing a surfactant containing more than a specific amount of an alkylsulfuric acid salt, an alkanol amide, a polyoxyethylene fatty acid amide or an amine oxide. CONSTITUTION: This high density granular detergent composition having >=0.6g/cc bulk density and high biodegradability and containing an alkyl sulfuric acid salt is obtained by blending (A) 20-50wt.% of a surfactant containing >=30wt.% alkylsulfuric acid salt (e.g., a sodium salt of an alkylsulfuric acid derived from palm oil, etc.) based on the sum total of the surfactant with (B) 0.5-3wt.% of an alkanol amide (e.g., an alkanol amide derived from palm oil, etc.) expressed by formula I (R1 is a 10-12C alkyl; R2 is H or CH3 ; (n1 ) is 1-3; (n2 ) is 0-3), a polyoxyethylene fatty acid amide or an amine oxide expressed by formula II (R3 is a 10-12C alkyl), adding an inorganic builder (e.g., sodium tripolyphosphate, etc.) and water thereto and spray drying the mixture.
Abstract:
PROBLEM TO BE SOLVED: To provide a method capable of producing a powder detergent composition in which the influence of an acid precursor of an anionic surfactant on the color of detergent particles is reduced. SOLUTION: The method for producing a powder detergent composition comprises: a step (a) for dissolving a fluorescent dye in a solvent; a step (b) for mixing a solution obtained by the step (a) with an acid precursor of an anionic surfactant; and a step (c) for bringing the mixture obtained by the step (b) into contact with a water-soluble alkaline inorganic substance to thereby neutralize the precursor of an anionic surfactant in the mixture.
