CI 77947 ●
TL;DR. This ingredient is primarily used as a mineral UV filter, helping protect skin by reflecting and scattering ultraviolet light. It also functions as a white pigment, opacifier, and soothing skin-protective agent in some formulas.
What does CI 77947 do in a cosmetic formula?
This ingredient is primarily used as a mineral UV filter, helping protect skin by reflecting and scattering ultraviolet light. It also functions as a white pigment, opacifier, and soothing skin-protective agent in some formulas.
Is CI 77947 clean?
This ingredient is broadly accepted in clean-beauty frameworks, especially in non-nano form, and has low allergy and irritation potential for most users. Main scrutiny centers on particle size, inhalation exposure in loose powders or sprays, and compliance with sunscreen regulations.
Is CI 77947 sustainable?
This material is mineral-derived or synthetically produced from mineral feedstocks, so it is not renewable in the plant-based sense. It is inorganic and does not biodegrade, but it is not a persistent organic pollutant, and particle size influences aquatic-risk discussions.
Is CI 77947 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets mineral-origin, purity, and non-nano requirements. From a Green Chemistry view, it scores well for stability and low skin reactivity, with tradeoffs around mining inputs and limited biodegradability relevance for an inorganic mineral.
How does CI 77947 work chemically?
The molecule is an inorganic metal oxide used in particulate form, where UV performance depends strongly on particle size, dispersion quality, and surface treatment. In sunscreens, it is commonly used across roughly 5% to 25% depending on jurisdiction and SPF target, and it is stable across typical cosmetic pH ranges but can agglomerate without good dispersants.
