CI 77947/Zinc Oxide ●
TL;DR. This ingredient functions as a mineral UV filter in sunscreens and as a white pigment or opacifier in color cosmetics and skin-care products. It provides broad UV coverage, especially in the UVA range, and adds opacity or coverage when used for color control.
What does CI 77947/Zinc Oxide do in a cosmetic formula?
This ingredient functions as a mineral UV filter in sunscreens and as a white pigment or opacifier in color cosmetics and skin-care products. It provides broad UV coverage, especially in the UVA range, and adds opacity or coverage when used for color control.
Is CI 77947/Zinc Oxide clean?
Clean-beauty frameworks generally accept this ingredient, especially in non-aerosol, non-powder formats, because it is well tolerated on skin and not a common sensitizer. The main scrutiny is particle size, inhalation exposure in loose powders or sprays, and transparent labeling when nano grades are used.
Is CI 77947/Zinc Oxide sustainable?
This material is mineral-derived and is not biodegradable in the way plant or fermentation ingredients are, but it is also not an organic persistent pollutant. Mining, energy use, and aquatic particle behavior, especially for very small particles, are the main sustainability considerations.
Is CI 77947/Zinc Oxide COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s mineral, purity, and nanomaterial requirements. From a Green Chemistry view, it scores well for photostability and low skin reactivity, but less well on renewability and mining-related sourcing impacts.
How does CI 77947/Zinc Oxide work chemically?
This ingredient is an insoluble inorganic metal oxide powder, often surface-treated to improve dispersion, reduce agglomeration, and control photocatalytic surface activity. As a UV filter, it is commonly allowed up to 25% in finished sunscreen in major markets, while pigment or opacifying use levels are formula-dependent and usually lower.
