Zinc Oxide 3.5%. Inactive: Purified Water ●
TL;DR. This ingredient primarily functions as an inorganic UV filter, helping scatter and absorb UVA and UVB radiation. It can also add opacity, coverage, and a mild soothing sensory profile in skin-care formulas.
What does Zinc Oxide 3.5%. Inactive: Purified Water do in a cosmetic formula?
This ingredient primarily functions as an inorganic UV filter, helping scatter and absorb UVA and UVB radiation. It can also add opacity, coverage, and a mild soothing sensory profile in skin-care formulas.
Is Zinc Oxide 3.5%. Inactive: Purified Water clean?
Clean-beauty frameworks generally view it as a well-tolerated mineral filter with low allergy and irritation potential. The main scrutiny is particle size, inhalation exposure in loose powders or sprays, and whether nano-grade material is clearly disclosed.
Is Zinc Oxide 3.5%. Inactive: Purified Water sustainable?
This material is mineral-derived, so its supply chain depends on mining and mineral processing rather than renewable agriculture. It does not biodegrade like an organic molecule, and environmental assessment focuses on particle form, aquatic release, and wastewater behavior.
Is Zinc Oxide 3.5%. Inactive: Purified Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s purity and particle-size requirements, including conditions for nano forms. From a Green Chemistry lens, it scores well for stability and low skin reactivity, but less strongly on renewability and biodegradability.
How does Zinc Oxide 3.5%. Inactive: Purified Water work chemically?
The molecule is an insoluble inorganic lattice material used as fine particles that reflect, scatter, and absorb UV across a broad spectrum. In sunscreen products it is commonly used from low single digits up to about 25 percent depending on jurisdiction and SPF target, and dispersion quality, coating, and particle size strongly affect transparency, UV performance, and formula feel.
