Title:
GRANULAR DETERGENT COMPOSITION
Document Type and Number:
Japanese Patent JP3545644
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a granular detergent composition showing excellent detergency to stains containing nonpolar oil and/or oils and fats of low polarity in large amounts by including a crystalline silicate and sodium chloride (and/or potassium chloride) in a specific content ratio.
SOLUTION: The object composition is obtained by including (A) 3-25 wt.% crystalline silicate and (B) (i) sodium chloride atd/or (ii) potassium chloride in a weight ratio (ingredient A/ingredient B) of (60/40) to (89/2) and, if necessary, (C) 10-40 wt.% surfactant preferably consisting of (iii) an anionic surfactant and (iv) a nonionic surfactant in a weight ratio (ingredient iii/ingredient iv) of (33/67) to (90/10). The ingredient A shows the maximum pH value of ≥11 (at 25°C) in the case of 0.1% dispersion and needs preferably ≥5 mL of 0.1 N hydrochloric acid to make 1 L of the 0.1% dispersion be pH 10 and above all preferably is a crystalline silicate where SiO2/M2O (wherein M is an alkali metal) is 0.5 to 3.2.
