Porphyridium Phycoerythrin | Natural Pink Pigment

EarthHue Erythro-Pink 150 is a standardized phycoerythrin extract derived from the red microalgae Porphyridium cruentum. Phycoerythrin is a red phycobiliprotein that captures light energy in the yellow-green spectrum and emits a distinctive pink-to-red fluorescence — a property that makes it uniquely valuable in both cosmetic coloration and life-sciences diagnostic applications.

As a colorant, phycoerythrin delivers a soft, luminous pink-red shade that is difficult to replicate with conventional plant-derived pigments. Its natural fluorescence gives cosmetic formulations — particularly lip glosses, blushes, and highlighters — a subtle, light-reflective quality that enhances visual appeal under both natural and artificial light. In the diagnostic sector, highly purified phycoerythrin (R-PE and B-PE conjugates) is a cornerstone fluorophore used in flow cytometry, immunoassays, and fluorescence microscopy.

EarthHue Erythro-Pink 150 is produced in controlled photobioreactors to ensure consistent pigment quality and freedom from environmental contaminants. The extraction and purification process is optimized to preserve the protein's structural integrity, fluorescence quantum yield, and color stability.

The product holds FDA GRAS status and is available in food/cosmetic-grade and diagnostic-grade purification levels. Cosmetic-grade material complies with relevant EU cosmetic ingredient regulations. Custom concentrations, buffer formulations, and conjugation-ready grades can be provided for diagnostic partners.

For cosmetic formulators seeking a distinctive natural pink with luminous depth, and for diagnostic manufacturers requiring a reliable phycoerythrin supply, EarthHue Erythro-Pink 150 bridges the gap between natural color and high-performance biochemistry.
