  • Examples 34 to 43 The purified water is heated to 70 ° C. to 80 ° C., and the higher fatty acid salt of component (A) and the polyhydric alcohol of component (D) are dissolved and cooled to 40 ° C. or less, the cation of component (B) Of the total amount of the liquid skin cleanser composition finally obtained by adding the hydrophobic polymer, the nonionic surfactant of the component (C), and the amidopropyl betaine of the component (E) to a total amount of 95% by mass A skin cleanser composition was prepared.
  • each liquid skin cleanser composition of Examples 34 to 43 obtained was filled in a container with a former pump dispenser [discharge volume 3 mL, nozzle diameter (inner diameter) 3.5 mm, manufactured by Yoshino Kogyo Co., Ltd.] .
  • Each liquid skin cleanser composition of Examples 34 to 43 is put up to the mouth of the glass bottle in a cylindrical transparent glass bottle having a diameter of 4 cm and a height of 7.5 cm, and the pocket size near vision card 40 cm (Inc. TIM) were placed, the marks on the card were observed, and "transparency" was evaluated based on the following evaluation criteria.
  • required the average score of 10 expert evaluators, and was judged based on the following judgment criteria. In addition, if an average evaluation point is 4.0 points or more, "transparency" is favorable.
  • the liquid skin cleanser composition of the present invention is excellent in the amount of foam, the elasticity of the foam, the good foamability, the stability at a low temperature, and the dischargeability, but the irritability at the time of cleaning Because it is excellent in moisturizing feeling at the end of rinsing and after towel drying, it is suitably used for, for example, face wash, hand soap, body soap, cleansing foam, makeup remover, etc., particularly for body soap Used.
