Description

technical field [0001] The invention relates to the technical field of fresheners, in particular to a photocatalyst formaldehyde-removing freshener and a preparation method thereof. Background technique [0002] Formaldehyde is an organic chemical substance. It is a colorless and irritating gas that is irritating to human eyes and nose. In the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization, formaldehyde is listed in the first class of carcinogens. Long-term exposure to formaldehyde will reduce the body's respiratory function, nervous system information integration function and affect the body's immune response. It also has toxic effects on the cardiovascular system, endocrine system, digestive system, reproductive system, and kidney. Systemic symptoms include headache, fatigue, loss of appetite, palpitations, insomnia, weight loss, and autonomic disturbances. Animal experiments also confirmed the pathologic...
