Non-Coated Zinc Oxide: 22% Water ●
TL;DR. This ingredient functions primarily as a mineral UV filter, forming a particulate layer that scatters and absorbs UVA and UVB radiation. It can also add opacity, coverage, and a soft matte finish in skin care and color cosmetics.
What does Non-Coated Zinc Oxide: 22% Water do in a cosmetic formula?
This ingredient functions primarily as a mineral UV filter, forming a particulate layer that scatters and absorbs UVA and UVB radiation. It can also add opacity, coverage, and a soft matte finish in skin care and color cosmetics.
Is Non-Coated Zinc Oxide: 22% Water clean?
Clean-beauty frameworks generally view it as an acceptable mineral screen, especially when particle size and inhalation exposure are controlled. The main caveats are white cast, possible dryness in some formulas, and greater surface reactivity when the particles have no separate surface treatment.
Is Non-Coated Zinc Oxide: 22% Water sustainable?
This material is mineral-derived and not biodegradable, so the sustainability profile depends on mining impacts, particle management, and release from rinse-off products. Its insoluble particulate form can remain in the environment, although it is not associated with the same bioaccumulation profile as many synthetic persistent materials.
Is Non-Coated Zinc Oxide: 22% Water COSMOS-approved?
It is permitted under COSMOS natural and organic standards as an approved mineral colorant or UV-filter material when regulatory and particle-size requirements are met. From a Green Chemistry lens, it scores well for functional efficiency and low-dose performance, but less well for nonrenewable sourcing and lack of biodegradability.
How does Non-Coated Zinc Oxide: 22% Water work chemically?
This material is an insoluble inorganic particulate with a high refractive index, and sunscreen use commonly ranges from low single digits up to the regulatory ceiling of about 25%, with 22% representing a high-load level. It is stable across typical cosmetic pH ranges, but dispersion quality, particle size, and surface treatment strongly affect whitening, viscosity, aggregation, and photo-reactivity in SPF systems.
