There are various types of bacteria, fungi, viruses and other microorganisms existing in our daily life. Therefore, how to deal with these microorganisms to effectively ensure the good health of human beings has become a hot spot, and antibacterial materials play an important role in this regard. Some special organic compounds, such as the types of biguanides, phenol ethers, thiazoles, chlorides, quaternary ammonium salts, etc, can react with protein groups (e.g., sulfhydryl group)to destroy the bacterial metabolic activity. These materials show the fast and strong bactericidal ability with easy processing and good stability. WKS-2, a new generation type of broad-spectrum high-efficiency antibacterial and antiseptic product, is independently developed and produced by Shanghai Huzheng Company. A large number of experiments and practical applications have proved that the product is effective in the cosmetics system for most bacteria which is difficult to be controlled, and shows good compatibility with organic and inorganic components. This product does not contain formaldehyde or formaldehyde slow-release substances and can be commonly used in various washing-typedaily chemicals.
