Rubixanthin

Rubixanthin (CAS 3763-55-1), also marketed as Natural Yellow 27 and approved under E161d, is a carotenoid pigment derived from rose hips. It delivers yellow-to-orange coloration in food, cosmetic, and nutritional applications.

Its natural origin positions it as a preferred alternative to synthetic colorants in clean-label and regulated markets. In food and beverage manufacturing, it functions as a natural colorant in products such as confectionery and dairy.

The material is used in beverages where E161d approval supports EU market compliance. Cosmetic formulators incorporate it into skincare and color cosmetics to provide pigmentation alongside antioxidant stabilization of the formula.

In nutritional supplements, it is used as both a colorant and a carotenoid active in softgels and capsules targeting antioxidant positioning. Animal feed producers apply it to enhance the pigmentation of poultry skin and egg yolks.

Carotenoid deposition is a measurable quality parameter in these agricultural applications. Rubixanthin is supplied as a powder or oil suspension, with concentration standardized to defined carotenoid content for industrial use.

Food-grade material conforming to E161d specifications is the primary commercial form. Availability can be limited relative to more abundant carotenoids, so buyers should confirm supply continuity before committing.

Batch documentation should be reviewed during formulation development to ensure consistency. This specialty pigment remains a niche but vital component for manufacturers seeking specific natural yellow-to-orange hues in their product lines.
