Zinc Oxide 15.5% ●
TL;DR. This ingredient is an inorganic UV filter that scatters and absorbs UV radiation, with strong UVA coverage and added opacity in color cosmetics. At this listed level, its main role is sun protection.
What does Zinc Oxide 15.5% do in a cosmetic formula?
This ingredient is an inorganic UV filter that scatters and absorbs UV radiation, with strong UVA coverage and added opacity in color cosmetics. At this listed level, its main role is sun protection.
Is Zinc Oxide 15.5% clean?
It is generally low-irritation and non-sensitizing on skin, including sensitive skin. Clean-standard friction usually centers on particle size, spray or loose-powder inhalation exposure, and label transparency for nano forms.
Is Zinc Oxide 15.5% sustainable?
This material comes from mined mineral feedstocks, so impacts are tied to extraction, purification, and particle processing rather than agriculture. It is inorganic and does not biodegrade, but it is not a persistent organic pollutant; very small particles raise aquatic-impact and sediment considerations in some assessments.
Is Zinc Oxide 15.5% COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards as an approved mineral UV filter, with nano forms subject to specific regulatory and labeling conditions. From a Green Chemistry lens, it scores well for low skin reactivity and functional efficiency, but less strongly on renewable sourcing and biodegradability because it is mined and inorganic.
How does Zinc Oxide 15.5% work chemically?
The molecule is an insoluble amphoteric inorganic lattice used as dispersed particles, often surface-treated to improve dispersion and reduce photo-reactivity. In sunscreens, active levels commonly run about 5 to 25%, it is stable across typical cosmetic pH ranges, and formula performance depends heavily on particle size, coating, dispersion quality, and film-forming partners.
