Question 1

What does Active Ingredients: Zinc Oxide 12%. Inactive Ingredients: Aqua/Water/Eau do in a cosmetic formula?

Accepted Answer

This ingredient is a sunscreen it that helps protect skin from both UVB and UVA exposure. It functions mainly by absorbing, reflecting, and scattering ultraviolet radiation at the skin surface.

Question 2

Is Active Ingredients: Zinc Oxide 12%. Inactive Ingredients: Aqua/Water/Eau clean?

Accepted Answer

From a clean beauty perspective, this ingredient is generally well accepted and has low irritation potential. Friction usually relates to particle size, spray formats, and surface coatings, rather than routine use in creams or lotions.

Question 3

Is Active Ingredients: Zinc Oxide 12%. Inactive Ingredients: Aqua/Water/Eau sustainable?

Accepted Answer

This material is mineral-derived, so its footprint is tied to mining, refining, and particle processing. It is not biodegradable because it is inorganic, and environmental behavior depends on particle size, coatings, and how much reaches waterways.

Question 4

Is Active Ingredients: Zinc Oxide 12%. Inactive Ingredients: Aqua/Water/Eau COSMOS-approved?

Accepted Answer

It is generally permitted in COSMOS-natural and COSMOS-organic products when the grade, coatings, and nanomaterial disclosures meet the standard. Its Green Chemistry profile is mixed, with strong points for skin tolerance and stability, but weaker alignment on renewability and biodegradability.

Question 5

How does Active Ingredients: Zinc Oxide 12%. Inactive Ingredients: Aqua/Water/Eau work chemically?

Accepted Answer

This compound is an insoluble inorganic particulate with a wide band gap, and its UV performance depends on particle size, dispersion quality, crystal form, and surface treatment. Sunscreen formulas commonly use about 5% to 25% it by weight, so the stated 12% level is within a typical range and requires good suspension and dispersion control to limit whitening, settling, or viscosity drift.
