Active: Zinc Oxide 15%. Inactive: Water ●
TL;DR. This ingredient functions primarily as a mineral UV filter, helping provide broad-spectrum sun protection while also adding opacity and a dry, slightly matte feel.
What does Active: Zinc Oxide 15%. Inactive: Water do in a cosmetic formula?
This ingredient functions primarily as a mineral UV filter, helping provide broad-spectrum sun protection while also adding opacity and a dry, slightly matte feel.
Is Active: Zinc Oxide 15%. Inactive: Water clean?
From a clean-beauty perspective, it is generally well accepted because it is low-sensitizing and not a formal allergen concern. Friction usually centers on particle size, inhalation concerns in loose powders or sprays, and documentation around surface coatings.
Is Active: Zinc Oxide 15%. Inactive: Water sustainable?
This material is mineral-derived and not biodegradable in the organic sense, although it is chemically stable and does not behave like many persistent synthetic organics. Sustainability considerations are mainly tied to mining, refining energy, and aquatic-release questions for very small particles.
Is Active: Zinc Oxide 15%. Inactive: Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the grade, coating, and particle-size profile meet the standard’s requirements. Its Green Chemistry fit is mixed, since it is inert and useful at low formulation complexity, but it is nonrenewable and not biodegradable.
How does Active: Zinc Oxide 15%. Inactive: Water work chemically?
This compound is an insoluble inorganic particulate that protects mainly through UV absorption and scattering, with formula performance shaped by particle size, surface treatment, and dispersion quality. At 15% active use, it is a high-load sunscreen phase, and stability depends on suspension control, film-former compatibility, and preventing agglomeration over the product’s shelf life.
