Sunstone ●
TL;DR. This ingredient is a mineral powder used mainly for visual effect, color, and soft-focus shimmer in makeup and skin-care formulas. In scrub formats, it can also add mild physical exfoliation depending on particle size.

Is Sunstone clean?
From a clean-standard lens, it is generally low-reactivity because it is an inert inorganic powder, but fine particles and trace metal impurities make supplier testing important. It is not a preservative, fragrance allergen, or common sensitizer.
Is Sunstone sustainable?
This material is mined, not grown or fermented, so the key sustainability questions are land disturbance, labor practices, and processing energy. It is not readily biodegradable in the organic sense, but it is an inert mineral and does not behave like a persistent synthetic polymer.
Is Sunstone COSMOS-approved?
It can align with COSMOS-natural when it is naturally sourced, processed only by allowed physical methods, and meets contaminant limits, but it would not count as organic. From a Green Chemistry view, its strengths are simple physical processing and low chemical reactivity, while its limitations are nonrenewable sourcing and no true biodegradation.
How does Sunstone work chemically?
This material is an inorganic aluminosilicate mineral lattice, usually used as a finely milled powder rather than a dissolved active. Performance and skin feel depend heavily on particle size, surface treatment, and dispersion, and mineral powders are generally stable across normal cosmetic pH ranges.
