Annatto

Annatto (CAS 1393-63-1), also known as roucou, achiote, and commercially designated E160b or C.I. Natural Orange 4, is a natural colorant derived from the seeds of Bixa orellana.

Where is Annatto used?

• Food: yellow-to-orange hues as a plant-based alternative to synthetic dyes
• Dairy: standard colorant for cheddar cheese, butter, and margarine
• Snack coatings, seasonings, and processed meat products: consistent warm color without synthetic additives
• Personal care: lip products, foundations, and skin-toning cosmetics
• It also functions as a mild flavoring agent in certain regional food applications.

Good to know: Concentration levels in commercial extracts are typically defined by percentage bixin or norbixin content, which buyers should confirm against application-specific requirements.

Commercial specifications

• Bixin content and norbixin content as primary specification markers
• Food-grade material to FCC standards; cosmetic-grade supply aligns with relevant regional colorant regulations
