Question 1

What does Uncoated Zinc Oxide 11% Inactive Ingredients: Aqua do in a cosmetic formula?

Accepted Answer

This ingredient is a mineral UV filter used in sunscreens and SPF cosmetics to help reduce UVA and UVB exposure. In this form, the water acts as the carrier for an 11% active dispersion.

Question 2

Is Uncoated Zinc Oxide 11% Inactive Ingredients: Aqua clean?

Accepted Answer

From a clean-beauty perspective, it is broadly accepted because it is a mineral sunscreen filter with low sensitization potential. The it form has more formulation friction because it can be more photoactive and may need careful antioxidant or dispersion support.

Question 3

Is Uncoated Zinc Oxide 11% Inactive Ingredients: Aqua sustainable?

Accepted Answer

This material is mineral-derived, so its footprint is tied to mining, purification, and particle processing rather than renewable agriculture. It is inorganic and does not biodegrade, but it can transform and settle in aquatic and soil systems depending on particle size, coating status, and wastewater conditions.

Question 4

Is Uncoated Zinc Oxide 11% Inactive Ingredients: Aqua COSMOS-approved?

Accepted Answer

It is generally permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s mineral-origin, particle-size, and regulatory conditions for sunscreen use. Its Green Chemistry fit is mixed, with strong functional efficiency and low skin sensitization, but limited renewable sourcing and no biodegradation.

Question 5

How does Uncoated Zinc Oxide 11% Inactive Ingredients: Aqua work chemically?

Accepted Answer

This compound is an inorganic semiconductor particle that attenuates UV through absorption, scattering, and reflection, with regulatory sunscreen use commonly capped at 25% in many markets. The it surface can catalyze oxidation under UV exposure, so formulators often manage dispersion quality, pH, chelation, antioxidants, and compatibility with film formers.
