Active ingredient: Zinc Oxide 22.4%. Inactive ingredients: Water ●

TL;DR. This ingredient is an inorganic sunscreen it that provides broad-spectrum UV protection, with especially strong UVA coverage at the level shown. The liquid phase is only the vehicle here, so the protective role comes from the dispersed solid it.

What does Active ingredient: Zinc Oxide 22.4%. Inactive ingredients: Water do in a cosmetic formula?

This ingredient is an inorganic sunscreen it that provides broad-spectrum UV protection, with especially strong UVA coverage at the level shown. The liquid phase is only the vehicle here, so the protective role comes from the dispersed solid it.

Is Active ingredient: Zinc Oxide 22.4%. Inactive ingredients: Water clean?

This ingredient is widely accepted in clean sunscreen standards because it is low-sensitizing and not a conventional organic UV absorber. Main clean-standard caveats are particle size, inhalable formats, and trace metal purity controls.

Is Active ingredient: Zinc Oxide 22.4%. Inactive ingredients: Water sustainable?

This material is mineral-derived, not renewable, and it does not biodegrade in the way plant or carbon-based ingredients do. It is generally persistent as an inorganic particle, so particle size, wastewater release, and responsible mining and refining are the key environmental considerations.

Is Active ingredient: Zinc Oxide 22.4%. Inactive ingredients: Water COSMOS-approved?

It is permitted under COSMOS natural and organic standards when the grade and use comply with the standard and applicable sunscreen regulations, with nano status and particle coatings needing documentation. From a Green Chemistry view, it scores for low skin reactivity and no solvent-intensive functionality, but it is mined, nonrenewable, and not biodegradable.

How does Active ingredient: Zinc Oxide 22.4%. Inactive ingredients: Water work chemically?

This compound is an insoluble ionic solid with a wide band gap, functioning by UV absorption plus scattering rather than by dissolving into the oil phase. Sunscreen use levels commonly range up to 25% in the U.S.; 22.4% is a high it level, and dispersion quality, particle coating, and pH control around neutral to mildly alkaline conditions affect transparency, feel, and stability.
