A lactoskin, which is the whey of the present invention without milk allergy, is obtained.

When the human body is washed with soap or body shampoo, the epithelial cells combine with anions to promote keratinization of the cells. Anions penetrate deeply into human cells and cause rough skin, and cations do not penetrate deeply when bound to epithelial cells and activate cells, so this anion is promptly exchanged with cations. It is then necessary to bind the cells with cations and prevent keratinization of the cells. From this point of view, lactoskin is an alginate ester, a hydrolyzed collagen solution, a bath skin cosmetic obtained by gelling with carrageenan, and a seaweed gel cake is applied to the whole body after bathing. It is thought that the derived anion is exchanged and a healthy protective film is formed.
