For the human body: (1) No irritation to skin: After years of animal and human tests, it has been shown that even if the skin directly contacts the pure CBS fluorescent whitening agent, it is not irritating to the skin and will not cause skin allergies. Optical brighteners are not absorbed by the skin. Even if the optical brightener CBS may adhere to the skin in a small amount during use, it will not react with human skin, and it is easy to be completely washed off through daily washing activities (such as hand washing, bathing, etc.) and will not be washed by the skin absorb. Therefore, direct skin contact with CBS-added laundry detergent will not cause harm; (2) No adverse effect on wound healing: The article "Toxicological Properties of Fluorescent Whitening Agents" published in "German Dermatology" in 1994 pointed out that even direct contact of optical brightener for textiles with wounds did not adversely affect wound healing or cause pathological changes in human skin; (3) Metabolism: For the fluorescent whitening agent CBS, it can be quickly and completely excreted through normal metabolism. Metabolic studies in mice show that after a large dose of optical brightener for detergents is fed, most of the whitening agent will be quickly excreted through the intestinal tract and will not be absorbed by the intestinal tract. No fluorescent whitening agent remains in its blood, liver, kidney, brain, muscle and fat, that is, it will not cause accumulation in the body. Therefore, even if a small amount of fluorescent whitening agent CBS enters the human body in daily life, it will be quickly excreted through the normal metabolic process; (4) The fluorescent whitening agent CBS has no teratogenicity and no carcinogenicity. Acute toxicity studies on a variety of animals and chronic toxicology experiments in mice for up to two years have proved that CBS is a non-toxic substance, non-teratogenic, non-carcinogenic, and non-mutagenic.
