ACTIVE INGREDIENT: 18.23% ZINC OXIDE ●
TL;DR. Its primary role is a broad-spectrum inorganic UV filter in sunscreens, helping attenuate both UVA and UVB exposure. It can also add opacity and a white cast in emulsions, sticks, and balms.
What does ACTIVE INGREDIENT: 18.23% ZINC OXIDE do in a cosmetic formula?
Its primary role is a broad-spectrum inorganic UV filter in sunscreens, helping attenuate both UVA and UVB exposure. It can also add opacity and a white cast in emulsions, sticks, and balms.
Is ACTIVE INGREDIENT: 18.23% ZINC OXIDE clean?
Clean-beauty frameworks generally accept this ingredient, especially in non-nano, well-dispersed forms, because sensitization is uncommon and it does not bring typical fragrance or preservative allergen issues. Fine powders and spray formats receive extra scrutiny because inhalation exposure changes the risk profile.
Is ACTIVE INGREDIENT: 18.23% ZINC OXIDE sustainable?
This material comes from mined mineral feedstocks, followed by purification, micronization, and sometimes surface coating. It is inorganic and not biodegradable in the usual sense, so environmental performance depends on particle size, coating, and how much is released into waterways.
Is ACTIVE INGREDIENT: 18.23% ZINC OXIDE COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic as an approved mineral-derived UV filter when it meets purity, particle-size, and coating requirements. Green Chemistry fit is partial: inert, photostable, and solvent-light in use, but nonrenewable and not biodegradable.
How does ACTIVE INGREDIENT: 18.23% ZINC OXIDE work chemically?
This compound is an amphoteric inorganic semiconductor with a crystalline lattice that attenuates UV mainly by absorption, with additional scattering that increases as particle size rises. Sunscreen it levels commonly run about 5 to 25%, with 18.23% sitting in the high-protection range, and performance depends heavily on dispersion quality, surface treatment, and compatibility with film formers.
