Pigment Black 11

Pigment Black 11 (CAS 12227-89-3), also known as Iron Oxide Black and approved as E172(i) in food applications, is a synthetic iron oxide pigment delivering deep black coloration. Its high tinting strength and chemical stability make it a preferred inorganic colorant where consistent, durable black hues are required across a broad range of industrial and consumer formulations.

In architectural and decorative coatings, it provides UV-stable black tones for exterior paints, roof coatings, and concrete colorants without the fading associated with organic alternatives. Plastics compounders incorporate it into masterbatches for automotive components, pipes, and packaging films where heat-stable coloration is critical during high-temperature processing.

In construction materials, it colors cement, paving blocks, and tiles throughout the mass, ensuring color uniformity that surface coatings cannot achieve for long-term durability. Food-grade E172(i) grades are used in specific confectionery and olive coloring applications where regulatory compliance is mandatory for safety and consumer protection standards.

Pigment Black 11 is supplied as a fine powder in both synthetic and natural grades. Standard specifications include food-grade, cosmetic-grade, and technical-grade options for various uses. Synthetic grades offer tighter particle size distribution for coatings and plastics. Dispersion forms and surface-treated variants are available for water-based and solvent-based systems.
