Zinc Oxide 17.42%. Inactive: Dimethicone ●
TL;DR. This ingredient is a physical UV filter that provides broad-spectrum sunscreen coverage by reflecting, scattering, and absorbing UV radiation. The listed inactive material helps spreadability, slip, and film formation on skin.
What does Zinc Oxide 17.42%. Inactive: Dimethicone do in a cosmetic formula?
This ingredient is a physical UV filter that provides broad-spectrum sunscreen coverage by reflecting, scattering, and absorbing UV radiation. The listed inactive material helps spreadability, slip, and film formation on skin.
Is Zinc Oxide 17.42%. Inactive: Dimethicone clean?
The active filter is generally well-tolerated and often accepted in clean-beauty frameworks, with caveats around particle size and inhalation exposure in loose powders or sprays. The listed inactive film-forming polymer creates clean-standard friction because many natural-focused standards do not accept it.
Is Zinc Oxide 17.42%. Inactive: Dimethicone sustainable?
This material is mineral-derived and not biodegradable in the way plant-based carbon ingredients are, but it is generally persistent as an inert solid rather than a bioaccumulative organic compound. Fine particles can affect aquatic systems depending on coating, size, and dissolved metal release, and the listed inactive polymer adds persistence concerns.
Is Zinc Oxide 17.42%. Inactive: Dimethicone COSMOS-approved?
The active filter can be permitted under COSMOS-natural and COSMOS-organic when it meets restrictions on particle form, coatings, and processing. The listed inactive polymer is not aligned with COSMOS natural criteria, so the blend as listed has a compromised Green Chemistry profile.
How does Zinc Oxide 17.42%. Inactive: Dimethicone work chemically?
The active portion is an inorganic, insoluble metal-oxide powder listed here at 17.42%, a level typical of high-protection sunscreen formulas. It is stable across normal cosmetic pH ranges, but dispersion quality, surface coating, particle size, and film uniformity strongly affect UV performance and skin feel.
