Titanium dioxide (titanium dioxide) is a white pigment widely used in the cosmetics industry. It is favored for its excellent optical properties, chemical stability and biosafety. The following are the main applications of titanium dioxide in cosmetics and their functions.
Application Scope
1. Makeup Products
- Foundation: Titanium dioxide can provide good coverage and make the skin look smoother and more even.
- Pressed Powder: As an important concealer, titanium dioxide can effectively cover skin blemishes.

3. Enhance texture
- Titanium dioxide can increase pleasure and improve skin texture, making the skin look smoother and tenderer.
4. Anti-ultraviolet
- Titanium dioxide has a high refractive index and can reflect and scatter ultraviolet rays, thereby achieving anti-ultraviolet effects. Therefore, titanium dioxide is widely used in sunscreens.
Safety
As a pigment and filler for cosmetics, titanium dioxide has certain restrictions on its use and addition. The amount of titanium dioxide added to cosmetics should not exceed 25% of the total amount of raw materials, and it also needs to undergo a certain safety assessment. Due to its large particle size, it will not be absorbed on the skin and has good safety.
Precautions for use
1. Mixed use
- Titanium dioxide has poor ductility and is not easy to mix evenly with other powders, so it is best to mix it with zinc dioxide to overcome this deficiency.
2. Usage amount
- The amount used in cosmetic powder products should be within 10% to ensure the stability and safety of the product.
Conclusion
Titanium dioxide plays an important role in cosmetics. Its high whiteness and hiding power can bring a good texture to makeup and skin care products. At the same time, because it does not absorb and can filter ultraviolet rays, it also increases its application in sunscreen products. Overall, titanium dioxide is a safe and reliable cosmetic raw material.
