Non-Nano Zinc Oxide ●
TL;DR. This ingredient is a mineral UV filter that attenuates both UVA and UVB as insoluble particles on the skin. It can also add opacity, coverage, and a drier skin feel in creams, lotions, sticks, and powders.
What does Non-Nano Zinc Oxide do in a cosmetic formula?
This ingredient is a mineral UV filter that attenuates both UVA and UVB as insoluble particles on the skin. It can also add opacity, coverage, and a drier skin feel in creams, lotions, sticks, and powders.
Is Non-Nano Zinc Oxide clean?
It is widely accepted in stricter clean frameworks when supplied in larger particle grades, with low sensitization potential compared with many organic UV filters. Main scrutiny is inhalation exposure in loose powders or sprays and trace metal impurities, which reputable suppliers control by specification.
Is Non-Nano Zinc Oxide sustainable?
This material is mineral-derived or synthetically precipitated from mined inputs, so it is not renewable and it does not biodegrade. Larger, coated particles are less mobile than smaller particle grades, but release to waterways remains a formulation and end-of-life consideration.
Is Non-Nano Zinc Oxide COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic as an allowed mineral ingredient and UV filter when it meets particle-size, purity, coating, and nanomaterial disclosure rules. From a Green Chemistry view, it scores for inertness and low skin reactivity, but less well for non-renewable sourcing and lack of biodegradability.
How does Non-Nano Zinc Oxide work chemically?
The molecule is an inorganic metal oxide lattice supplied as insoluble micron-scale particles, often surface-treated to improve dispersion and reduce photocatalytic activity. Typical sunscreen use is about 5 to 25%, it is stable across normal cosmetic pH, and it needs strong dispersion because it can thicken emulsions, increase opacity, and interact with some anionic polymers or electrolytes.
