Heart of beauty in everyone. But what happens when "Aimei" encounters talcum powder? Cosmetics are an indispensable "equipment" for Ms. Amy, and talcum powder has been used in the production of cosmetics for a long time. What happens when talcum powder and Amy collide together? Today, Xiaobian specially talked with you about the talcum powder in cosmetics, uncovering the mist of cosmetics and understanding the talcum powder from a scientific perspective.
The main component of talc powder is magnesium silicate mineral and hydrogen oxide mineral. Talc powder is used as a lubricant, absorbent, filler, anti-caking agent and sunscreen in cosmetics. Because of its functions of lubrication, absorption, filling, anti-caking, shading, etc., it has been widely used in various cosmetic productions, such as foundations and eye shadows, and has become an indispensable part of people's lives. Its softness stems from its unique sheet-like crystal structure, which reduces the frictional resistance between particles. The surface of this flaky crystal structure of talc has hydrophobicity, but the edge of the structure is hydrophilic, which makes it difficult to find a suitable substitute in cosmetics. In order to ensure the safety of cosmetics, the "Requirements for Talc Powder for Cosmetics" was issued by the State Food and Drug Administration on December 23, 2011, and was approved by the National Food and Drug Administration [2011] No. 500.

For talcum powder for cosmetics, there is an important indicator that “no asbestos can be detectedâ€. Than medicinal talcum powder. For example, in China's cosmetics testing standards, it is clearly stipulated that asbestos should not be detected in cosmetic ingredients. In order to make consumers more reassured, multi-national regulatory agencies and third-party testing agencies have long observed the safety of talcum powder. The long-term record of talcum powder for cosmetics is used to confirm the safety of talcum powder, and dozens of global medical experts Scientific research and clinical evidence from the past have also supported the safety of talc for cosmetics.
