Scheme introduction

The toxicity of cosmetic products is due to the presence of toxic substances in the raw materials or components of the cosmetic products, as the content of toxic substances exceeds the allowable limit, or the addition of certain toxic ingredients which are prohibited by the regulations. Cytotoxicity test is a multi-dimensional method to evaluate the toxicity level of raw materials to cells, which can guide the concentration of safe dosage, optimize the formulation and improve the quality of products.
