Zinc Oxide 17% ●
TL;DR. At 17%, this ingredient functions as a mineral UV filter, helping protect skin by absorbing, scattering, and reflecting UV radiation in sunscreen formulas.
What does Zinc Oxide 17% do in a cosmetic formula?
At 17%, this ingredient functions as a mineral UV filter, helping protect skin by absorbing, scattering, and reflecting UV radiation in sunscreen formulas.
Is Zinc Oxide 17% clean?
It is generally accepted in clean-beauty standards, especially in non-aerosol creams and lotions, because it is low-sensitizing and not a common allergen. Main scrutiny is particle size, surface coating, and inhalation exposure in loose powders or sprays.
Is Zinc Oxide 17% sustainable?
This material is mineral-derived and made through mining, refining, and high-temperature processing, so it is not renewable or biodegradable in the usual organic-chemistry sense. It is insoluble and persistent as a mineral particle, with aquatic-impact questions mainly tied to particle form, coatings, and release levels.
Is Zinc Oxide 17% COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s conditions for approved mineral ingredients and particle specifications. Its Green Chemistry fit is mixed, with strong stability and low skin reactivity, but limited renewability and energy-intensive processing.
How does Zinc Oxide 17% work chemically?
This compound is an insoluble inorganic metal oxide used in sunscreens at regulated active levels, with 17% sitting in a common range for broad-spectrum mineral protection. It is photostable across normal cosmetic pH ranges and is often surface-treated or dispersed with film-formers to improve spread, reduce whitening, and maintain even UV coverage.
