CI 77007 (Ultramarine Blue) (CAS 57455-37-5) appears in 1 of the 2,168 car-care products CarCareTruth tracks (as of August 2026).

Ultramarine Blue (CI 77007 / Pigment Blue 29) is an FDA-approved, cosmetic-grade inorganic pigment permitted in externally applied cosmetics and widely used in eye makeup, soap, and bath products. Not classified under GHS at the mixture level in this product's SDS. No carcinogen, asthmagen, or reproductive-toxicity listing.

CI 77007, commonly known as Ultramarine Blue (or Pigment Blue 29), is a synthetic sodium aluminosilicate pigment chemically identical in structure to the natural mineral lazurite, historically ground from lapis lazuli. It is one of the oldest blue pigments in continuous industrial use.

In car-care formulations it appears at trace concentration purely to give the product its visible color; it plays no role in cleaning, polishing, or protective performance. The same pigment is FDA-approved for use in cosmetics, including eye-area products, which reflects its long safety record at the low concentrations typical of colorant use. It is chemically inert under normal storage and use conditions.
