ColorantMineral

Appears in 2 scanned products.

In personal care

A blue pigment, either mined from the mineral lazurite or manufactured synthetically to the same chemical structure, composed mainly of sodium aluminum sulfosilicate.

Why it’s used

It is used to add blue coloring to soaps, bath products, and cosmetics.

What the evidence says

The only cited source is the FDA regulation permitting ultramarines (including Ultramarine Blue, CI 77007) for use in externally applied cosmetics, including products used near the eye, subject to purity limits on lead, arsenic, and mercury and 'good manufacturing practice' amounts. The regulation does not describe any toxicological concern, adverse effect, or safety controversy; it is a permissive listing rather than a hazard assessment. No data on dose-response, systemic absorption, or irritation studies are presented in this document.

Context

Used in both rinse-off and leave-on color cosmetics; stability, not safety, is the main formulation consideration, particularly in low-pH products.

No credible concern — for ultramarinesThis grade comes from research into ultramarines rather than into CI 77007 itself — we found no study of CI 77007 on its own. Evidence about ultramarines is weaker evidence about CI 77007 than a study of CI 77007 would be, so the grade is capped at “suggestive”, however strong the research is.

Nothing here makes a claim to grade.
