Description

Zinc Oxide is a widely used mineral active in cosmetic products, especially sunscreens, due to its broad-spectrum UV protection, anti-inflammatory properties, and skin-soothing effects. As a physical UV filter, its quality, purity, and particle size directly impact product performance, stability, and safety. Therefore, precise testing of Zinc Oxide is essential for compliance, efficacy, and consumer trust.

At Auriga Research, we offer specialized Zinc Oxide Active Testing for cosmetic and personal care formulations, including sunscreens, creams, ointments, and powders. Our analytical methods are aligned with international standards to ensure accurate quantification and characterization.
