Background

As is well known, the skin pH value of human body is 4.0 at the lowest and can reach 9.6 at the highest, especially the skin pH value of infants is lower, and the average pH value is between 5.0 and 7.0.

the outermost layer of the skin is a leather lipid film which is thinner than the preservative film, and the toilet soap with high pH value can damage the leather lipid film of the skin, so that the skin loses the protective capability, cannot store enough moisture, and is easy to cause skin aging, dryness, itch and allergy. Therefore, the use of a product with too high alkalinity can cause a great loss of sebum, reduce the alkali neutralization capacity of the skin and cause skin damage.

the pH value of the prior toilet soap product for bathing is as high as 10.57 and is far higher than the pH value of skin, the toilet soap has the advantage of strong cleaning capability, but has the technical problems of high alkalinity, dry and tight feeling after cleaning, insufficient moisture retention and moistening degree and the like, and aiming at the technical problems, the invention develops a milder and non-irritant facial and skin-moistening soap with the pH value being attached to a human body.
