Is Shu Fujia an alkaline soap?

Shufujia soap is weak in alkalinity and acidity. There are two kinds of soaps: acidic and alkaline. However, because human skin is acidic, if we use strong acidic soap, the acid value of the skin will rise, the skin will be dry and the human body will be uncomfortable. Similarly, if people use strong alkaline soap, their skin will be uncomfortable. However, the vegetable soap with weak alkali and weak acid does not affect the recovery ability of the skin itself, and the original PH value of the skin surface can be recovered after washing 15-30 minutes, so people use the soap with weak alkali and weak acid.
