Cosmetic

Commonly used additives in cosmetics include antioxidants, preservatives, moisturizers, surfactants, flavors, pigments and special additives.

Antioxidants are used to prevent the active ingredients in skin care products from oxidizing and producing oxides, enzymes, acids, etc., which will cause the cosmetics to change color and deteriorate.

Preservatives are used to inhibit the reproduction of microorganisms that may occur in cosmetics and secondary pollution caused by consumers' use. The requirements for preservatives used in cosmetics are that they do not affect the color of the product, have no odor, and are non-toxic within the normal scope of application. No irritation to skin.

The stratum corneum of the human epidermis contains natural moisturizing factors to keep the skin moist. Cosmetics have the same function as the sebum film. They are often developed based on the sebum film, so moisturizers that simulate the skin's natural moisturizing factors are indispensable.

A certain amount of essence is added to cosmetics to make the cosmetics have an attractive fragrance and make people feel happy. There are three types of raw materials for fragrance: plant-based, animal-based and synthetic. It is generally made up of a mixture of various ingredients, but they are all applicable ingredients as long as they are within the specified range.
