The higher alcohol or ester oil having a branched chain alkyl group of 4 to 22 can improve the feeling of use without impairing the emulsion stability of the stock solution and the stability of the ejected amount over time. However, when compounded in the second agent, the carbon number is 1
If the blending amount of the higher alcohol having a branched chain alkyl group of 4 to 22 is less than 0.5% by mass, the feeling of use will not be improved, and if it exceeds 5.0% by mass, the ejection amount will change with time. Therefore, it is necessary to be 0.5 to 5.0 mass%. If the amount of the ester oil is less than 0.5% by mass, the feeling of use will not be improved, and
