Question 1

What does Active ingredient: Zinc Oxide 16.0% Inactive ingredients: Water do in a cosmetic formula?

Accepted Answer

This ingredient is a mineral UV filter that helps protect skin by absorbing, scattering, and reflecting ultraviolet radiation. At 16%, it is being used as the it sunscreen component in a very simple water-based formula.

Question 2

Is Active ingredient: Zinc Oxide 16.0% Inactive ingredients: Water clean?

Accepted Answer

This ingredient is generally well accepted in clean beauty, especially in non-nano form, and is usually considered low-irritation for skin. The main clean-standard caveats are particle size, inhalation concerns in loose powders or sprays, and potential impurities controlled by cosmetic-grade specifications.

Question 3

Is Active ingredient: Zinc Oxide 16.0% Inactive ingredients: Water sustainable?

Accepted Answer

This material is mineral-derived, so it is not renewable and depends on mining and refining. It is inorganic and does not biodegrade, although larger, coated, or non-nano particles are generally viewed as lower concern than highly mobile nanoscale particles in aquatic settings.

Question 4

Is Active ingredient: Zinc Oxide 16.0% Inactive ingredients: Water COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic standards when it meets the standard’s conditions, including particle-size and purity requirements. From a Green Chemistry perspective, it scores well for skin tolerance and functional efficiency, but less strongly on renewable sourcing and biodegradability.

Question 5

How does Active ingredient: Zinc Oxide 16.0% Inactive ingredients: Water work chemically?

Accepted Answer

This compound is an insoluble inorganic particulate that functions through broad-spectrum light attenuation, with stronger coverage in the UVB and UVA range when properly dispersed. Sunscreen use levels commonly fall from about 5% to 25%, and performance depends heavily on particle size, coating, dispersion quality, and film uniformity.
