CI 77947

Description

CI 77947, 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 a skin protectant. Zinc oxide effectively blocks both UVA and UVB rays, providing broad-spectrum protection against sun damage and premature aging.

In skincare, zinc oxide is prized for its gentle nature, making it suitable for sensitive skin types and even infants. It exhibits antimicrobial properties, which can be beneficial in treating acne and minor skin irritations. As a non-comedogenic ingredient, it doesn't clog pores, making it an excellent choice for oily and acne-prone skin.

CI 77947 also functions as a white pigment in cosmetic products, providing opacity and coverage. Its particle size can be manipulated to create different effects, from sheer to opaque finishes. In recent years, nanoparticle forms of zinc oxide have been developed to reduce the white cast typically associated with physical sunscreens, while maintaining its protective properties. However, the safety and efficacy of nanoparticle zinc oxide continue to be subjects of ongoing research in the skincare community.
