Spirulina platensis is a cyanobacteria biomass rich in proteins (60–70%), phycocyanin, chlorophyll, carotenoids, and essential fatty acids. Used as a natural blue-green pigment with documented antioxidant and anti-inflammatory bioactivity, it is positioned in cosmetics as a functional active rather than a decorative colorant. Optimal stability is at pH 6–7 under cold processing (<40 °C). It aligns strongly with clean-label, vegan, and sustainable trends
Spirulina is a nutrient-dense microalga containing more than 60% high-quality plant protein, phycocyanin, β-carotenes, chlorophyll, essential fatty acids, and minerals. Sustainably cultivated in closed photobioreactors and supplied as a stable
B-Phycoerythrin (B-PE) pigment comes from the marine microalga Porphyridium sp. It delivers a vivid purple-pink color, strong antioxidant power, and immune support. Manufacturers can choose from purity grades E16, E18,
Dunaliella salina is a halotolerant microalgae extract rich in carotenoids, primarily β-carotene in both all-trans and 9-cis forms, along with lutein and zeaxanthin. These compounds provide effective lipid-phase antioxidant protection
