COMPOSITION D'AGENT NETTOYANT POUR LA PEAU OU POUR LES CHEVEUX CONTENANT UN AGENT GÉLIFIANT AQUEUX, ET PROCÉDÉS DE FABRICATION D'AGENT GÉLIFIANT AQUEUX ET DE COMPOSITION D'AGENT NETTOYANT
The present invention has an object to provide a cleansing composition which exhibits flow properties suitable for a skin- or hair-cleansing agent, has high temperature stability in terms of the viscosity thereof, exhibits excellent foaming properties and sustained foaming properties, and imparts a favorable texture (fresh feeling) when applied. In order to achieve this object, this invention provides a skin- or hair-cleansing composition which contains a component (A), which is an aqueous gelling agent represented by general formula (1) below, and a component (B), which is an anionic surfactant, wherein the viscosity of an aqueous solution containing 1 mass% of component (A) at 25°C is 1,000 to 5,000 mPa·s, the clouding point of the aqueous solution containing 1 mass% of component (A) is 60 to 80°C, and the weight average molecular weight of component (A) is 10,000 to 30,000； a method for producing the aqueous gelling agent； and a method for producing the cleansing composition.In the formula, R1, R2, R8 and R9 each independently denote a hydrocarbon group having 4 to 20 carbon atoms, R3, R5 and R7 each denote represent a divalent hydrocarbon group having 2 to 4 carbon atoms, R4 and R6 each independently denote a divalent hydrocarbon group having 3 to 16 carbon atoms, a and e each independently denote a number from 10 to 100, d denotes a number from 100 to 500, and g denotes a number from 0 to 10.
