CI 75170

Description

CI 75170, also known as Titanium Dioxide, is a versatile and widely used inorganic compound in skincare and cosmetic formulations. This white, opaque pigment offers excellent UV protection properties, making it a crucial ingredient in sunscreens and other protective skincare products.

Titanium Dioxide functions as a physical sunblock by reflecting and scattering both UVA and UVB rays. Its broad-spectrum protection helps prevent premature aging, sunburn, and skin damage associated with UV exposure. The ingredient is generally considered safe for most skin types, including sensitive skin, due to its low risk of irritation and allergic reactions.

In addition to its sun protection benefits, CI 75170 is valued for its ability to enhance the opacity and brightness of skincare and makeup products. It can improve the texture and spreadability of formulations while providing a matte finish to the skin. Titanium Dioxide is also photo-stable, meaning it maintains its effectiveness when exposed to sunlight.

When used in nano-sized particles, CI 75170 offers improved transparency on the skin, making it ideal for lightweight, invisible sunscreen formulations. However, concerns about potential nanoparticle absorption have led to ongoing research and regulatory scrutiny.
