Background

The bath foam is a liquid cleaning agent commonly used by modern people, is a liquid body cleaning and skin care product prepared by taking surface active and skin care as main raw materials, is sticky in appearance, and has cleaning and decontamination capability on the skin. Compared with the traditional soap as a bath product, the bath lotion has the characteristics of convenience in use, easiness in cleaning, hard water resistance, abundant foam, good skin smoothness after use and the like. Especially, the bath foam can not generate flaky soap scum which is similar to soap and floats on the water surface in the using process. Therefore, in recent years, the yield and sales of the bath cream are continuously increased, and the bath cream becomes a mainstream product of bath cleaning and conditioning products and gradually replaces the position of the soap.

However, most of the bath foam in the market at present mainly comprises chemical components, is not easy to wash, can cause rough skin after long-term use, and has larger harm to human skin due to the added preservative component. Harming one: cancer may be caused, and paraben is commonly called as p-hydroxybenzoate and is a preservative and sterilizing agent commonly used in cosmetics. In the special area of the bath foam in the supermarket, almost all bath foams contain preservative components such as polyquaternium, sodium xylene sulfonate, oxidized polyethylene and the like, and even some brand pure natural bath foams contain "paraben" clearly indicated on the component list. Molecular biologists in the united kingdom found that hydroxybenzoate was found in a large number of breast cancer tumors (20 ng in an average of 1 g of tissue) and exhibited the properties of estrogen (a hormone involved in the development of the breast cancer method), so it was thought that hydroxybenzoate might lead to an increased probability of developing breast cancer in women using the journal of toxicology in the united kingdom; and (2) harming: preservatives accelerate skin aging, as expressed by the cosmetic specialist Wangchang at Beijing university of Industrial and commercial: "on the one hand, preservatives are not metabolized by the human body and therefore accumulate on the human skin, which, when accumulated in a certain amount, accelerates the aging of the skin", and on the other hand, preservatives accelerate pigmentation, which leads to an increasing darkening of the skin, regardless of how touted by the trade company, a bath liquid containing preservatives which, after prolonged use, leads to a darkening of the skin. And (3) harming: causes skin allergy and dermatitis, and is represented by major principal any of the principal cardinal salves of dermatology in the first subsidiary hospital of the university of qinghua: the antiseptic can cause skin abnormal hyperplasia and canceration, and related components can be chemically changed under the irradiation of sunlight, so that people can have light sensitivity, skin redness, blackening and pain, people can have allergy, red and itching symptoms, or skin burn can be caused. In addition, bath foam cleanses the skin by removing excess dirt and oils, and frequent cleansing of the skin also removes natural oils and other natural conditioning and moisturizing ingredients from the skin, which can cause various skin problems such as dry skin, desquamation, itching, etc.
