The main functions of titanium dioxide in cosmetics include sun protection, whitening, concealer, anti-bacterial and anti-oxidation.
The main functions of titanium dioxide in cosmetics include sun protection, whitening, concealer, anti-bacterial and anti-oxidation. The specific mechanisms are as follows:
Sunscreen and UV Protection
Titanium dioxide effectively reduces UV penetration through the skin by reflecting and scattering UV rays (including UVA and UVB), preventing sunburn, photoaging, and photosensitive skin diseases. When the particle size is less than half the wavelength of the light wave, the shielding effect is optimal, and the transparency is high, which can avoid the skin from appearing unnatural pale.
Nanoscale titanium dioxide (such as VK-T02) can absorb ultraviolet energy more efficiently due to its finer particles, further enhancing its sun protection effect.
Whitening and Brightening
Reduce skin dullness by reflecting light, while inhibiting tyrosinase activity or preventing melanin production, resulting in uniform and bright skin tone.
Strong coverage, can cover spots or blemishes, and enhance skin texture.
Antibacterial and Anti-Inflammatory Properties
Titanium dioxide nanoparticles can generate reactive oxygen species (ROS), disrupt the structure of microbial cell membranes, and have antibacterial and antiviral effects, making them suitable for disinfection in hospitals or public places.
Regulate immune response and alleviate skin inflammation.
Other Auxiliary Functions
Oil absorption and control: Absorb excess oil and keep makeup dry.
Repair barrier: Promote keratinocyte proliferation and assist in repairing damaged epidermal layer.
Attention
Potential risks: Long term use may clog pores or cause allergies (such as redness, swelling, itching), sensitive skin should be used with caution.
Safety: Food grade titanium dioxide is non-toxic and odorless as an additive, but it must be ensured to meet safety standards in cosmetics.
