CI 77231

Description

CI 77231, also known as Zinc Oxide, is a versatile and widely used inorganic compound in skincare and cosmetic formulations. This white, powdery substance serves multiple functions, primarily as a physical sunscreen and skin protectant. Zinc Oxide effectively blocks both UVA and UVB rays, providing broad-spectrum protection against sun damage and photoaging.

In skincare, CI 77231 is renowned for its gentle, non-irritating properties, making it suitable for sensitive skin types and even infants. It possesses mild astringent and antiseptic qualities, which can help soothe minor skin irritations and promote healing. The ingredient also exhibits some anti-inflammatory effects, potentially benefiting conditions like rosacea and acne.

Zinc Oxide's opacity makes it an excellent choice for color cosmetics, particularly in foundations and concealers, where it can provide coverage while offering sun protection. Its particle size can be manipulated to create varying levels of transparency or opacity in formulations. When used in higher concentrations, CI 77231 can leave a white cast on the skin, which formulators must consider when developing products for diverse skin tones.
