Request SDS →Ultramarine blue (CAS 57455-37-5; C.I. Pigment Blue 29) is a synthetic inorganic sodium aluminosilicate pigment containing polysulfide chromophores. It is used as a blue colorant in paints and coatings, in plastics and printing inks, and as a cosmetic colorant, and is also applied as a bluing/whitening agent in detergents and similar products.
Frequently Asked Questions
What are ultramarines (the pigment) known for?
Ultramarine blue (CAS 57455-37-5; C.I. Pigment Blue 29) is a synthetic inorganic sodium aluminosilicate pigment containing polysulfide chromophores, known for its intense blue color. It is used as a colorant in paints and coatings, plastics and printing inks, and cosmetics, and as a bluing/whitening agent in detergents.
What are ultramarines in cosmetics?
In cosmetics, ultramarines are the same inorganic blue (and related violet/pink) aluminosilicate pigments used as colorants. They are supplied as a fine powder pigment for color cosmetics; confirm the cosmetic-grade specification and CoA when sourcing for that use.
What is the chemical composition of ultramarine pigment?
Ultramarine is a synthetic sodium aluminosilicate with polysulfide chromophores, approximate formula Al6Na8O24S3Si6, CAS 57455-37-5, indexed as C.I. Pigment Blue 29. The color arises from the trapped polysulfide groups within the aluminosilicate framework.
Is ultramarine pigment soluble in water?
Ultramarine is an inorganic pigment and is essentially insoluble in water and organic solvents; it colors by dispersion rather than dissolution. This insolubility is why it is used as a particulate pigment in paints, plastics, and powders. Consult the SDS for full physical data.
How is ultramarine pigment supplied in bulk?
Ultramarine is typically supplied as a dry powder pigment in bags or drums, with grade selected by application (paint, plastics, ink, cosmetic, or detergent bluing). Request a bulk quote from RawSource for grade availability, packaging, and CoA/SDS documentation.
