Abstract

An object of the present invention is to provide an easy-to-handle, before and after dilution with water, concentrated liquid cleanser composition and a production method thereof. A concentrated cleanser composition of the present invention is characterized by comprising: (A) an anionic surfactant, (B) an amphoteric surfactant, (C) 5 to 15 mass % of a monohydric or dihydric alcohol, (D) 8 to 18 mass % of a nonionic surfactant with the IOB value of 0.8 to 1.1 and the molecular weight of 500 or lower, and (E) 45 mass % or less of water, wherein the sum of (A) and (B) is 40 to 60 mass %; wherein the blending ratio (C):(D) is 3.5:1 to 1:2.5; and wherein the viscosity at 30° C. is 300 mPa·s or higher when the composition is diluted until the concentration of (A) and (B) becomes 15 mass %.

Claims

(A) an anionic surfactant,

(B) an amphoteric surfactant,

(C) 5 to 15 mass % of a monohydric or dihydric alcohol,

(D) 8 to 18 mass % of a nonionic surfactant with the IOB value of 0.8 to 1.1 and the molecular weight of 500 or lower, and

(E) 45 mass % or less of water,

wherein the sum of (A) and (B) is 40 to 60 mass %;

wherein the blending ratio (C);

(D) is 3.5;

1 to 1;

2.5; and

wherein the viscosity at 30°

C. is 300 mPa·
