Active: Zinc Oxide 15.11%. Inactive: Water ●
TL;DR. This ingredient is a mineral UV filter that provides broad-spectrum sunscreen coverage, especially strong UVA protection, by scattering, reflecting, and absorbing ultraviolet light. In this formula, water functions mainly as the carrier for the active dispersion.
What does Active: Zinc Oxide 15.11%. Inactive: Water do in a cosmetic formula?
This ingredient is a mineral UV filter that provides broad-spectrum sunscreen coverage, especially strong UVA protection, by scattering, reflecting, and absorbing ultraviolet light. In this formula, water functions mainly as the carrier for the active dispersion.
Is Active: Zinc Oxide 15.11%. Inactive: Water clean?
From a clean-beauty perspective, this ingredient is widely accepted and generally well tolerated on skin, with most scrutiny focused on particle size, inhalation exposure in loose powders or sprays, and coating quality. It is commonly favored in sensitive-skin and reef-conscious sunscreen standards, though some frameworks distinguish between non-nano and nano forms.
Is Active: Zinc Oxide 15.11%. Inactive: Water sustainable?
This material is mineral-derived, so its footprint is tied to mining, purification, and particle processing rather than agriculture. It is inorganic and not biodegradable in the usual organic-chemistry sense, but it is not designed to bioaccumulate and is relatively stable in use.
Is Active: Zinc Oxide 15.11%. Inactive: Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards for approved sunscreen use when it meets applicable particle-size, purity, and regulatory requirements. Its Green Chemistry fit is mixed, with good photostability and low skin reactivity, but nonrenewable mineral sourcing and limited biodegradability.
How does Active: Zinc Oxide 15.11%. Inactive: Water work chemically?
This compound is an insoluble inorganic particulate with a crystalline lattice that behaves as a wide-band-gap semiconductor, which explains its UV attenuation and photostability. Typical sunscreen use levels are about 5% to 25% active, and performance depends heavily on particle dispersion, surface coating, and film uniformity across the skin.
