Traditional pig pancreas soap is saponified with soda ash. The soda ash is not very alkaline and the saponification is incomplete. As a result, the minced pig pancreas meat is not completely destroyed and decomposed into small molecular compounds. Therefore, it is greatly affected by temperature and is easily affected by the temperature. It becomes soft and smelly as the temperature rises.

Pig soap has a long history of use in northern China. It was a commonly used bathing and decontamination cleaning product for the royal family and the people in ancient times.

Pig soap soap can not only wash away stains on the skin surface, but also has anti-freezing, anti-cracking and moisturizing functions. Long-term use can improve rough skin and make the skin tender. Modern research shows that pig pancreas is rich in digestive enzymes, such as protease, lipase, amylase, etc., which can promote the decomposition of protein, fat, starch and other macromolecules; pig pancreas also contains saponins, lecithin, protein, fat, calcium It contains ingredients such as , phosphorus, iron, vitamins b1 and b2, niacin, and insulin, so it has strong decontamination ability. It can also effectively prevent and treat cold and cracked hands, dry skin, and can whiten and moisturize skin.
