Porphyridium Cruentum Extract · 5% aqueous hydroglycerin stock
Discover Porphyridium Cruentum Extract, Formulate Labs' fixed 5% hydroglycerin stock harnessing the power of sulfated exopolysaccharides (EPS) and phycoerythrin proteins from red microalgae, offering superior skin hydration and matrix preservation without being tied to a specific supplier's marketing narrative.
Red microalga cultivated via blue biotechnology
Porphyridium Cruentum Extract is derived from the red microalga Porphyridium cruentum, cultivated via blue biotechnology. While other suppliers may market this ingredient as Porphyridium cruentum powder or biomass, Formulate Labs offers the pure INCI material, Porphyridium Cruentum Extract, ensuring transparency and formulation flexibility.
Dual mechanism: Porphyridium Cruentum Extract provides a dual-action approach to skin hydration and matrix preservation, positioning it as a high-performance vegan alternative to Hyaluronic Acid (HA) and Polydeoxyribonucleotides (PDRN). Upon topical application, the extract's matrix of sulfated exopolysaccharides (EPS) forms an immediate, non-occlusive shield on the skin's surface. This biomimetic film binds a significant amount of water, leading to a visible plumping effect and supporting skin hydration. Concurrently, the extract's components actively inhibit key enzymes responsible for the degradation of the dermal extracellular matrix, including elastase, collagenase (MMP-1), and hyaluronidase. This enzymatic inhibition helps preserve the skin's structural integrity, protecting it from signs of both chronological aging and exposome-induced damage.
Use levels: For Formulate Labs' fixed 5% hydroglycerin stock, incorporate at 0.5% – 5.0% into formulations.
Market context: Porphyridium Cruentum Extract is the core bioactive found in several premium, trade-name cosmetic actives. Formulate Labs supplies the pure INCI material, allowing formulators to build their own product stories based on the same powerful science without being tied to a specific supplier's marketing narrative. This INCI is the key component in actives such as Hydrintense™-class actives (marketed for cellular defense and long-lasting marine hydration), Marine SeaDew EPS-class actives (positioned as "super hydrating agents" that clinically outperform standard hyaluronic acid for immediate moisture-binding effects), and Zenitium-class actives (promoted for supporting skin longevity and barrier health while reducing the visible signs of aging induced by the exposome).
Pricing context: Public B2B pricing data specifically for cosmetic-grade liquid suspensions of Porphyridium Cruentum Extract is sparse. Market intelligence indicates that bulk dry extract powder can range from $200 to $800 per kilogram, with pricing dependent on factors like EPS standardization and organic certification. For Formulate Labs' liquid suspension, a realistic B2B price ladder is: 500 g sample: $117.00; 1 kg: $180.00; 17 kg drum: $2,601.00 ($153.00 / kg).

The cosmetic benefits of this extract are substantiated by peer-reviewed research. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
This clinical research validates the extract's capacity to significantly support skin hydration and improve visible texture and radiance. The findings support its use in formulations designed to achieve a plump, hydrated appearance comparable to that of hyaluronic acid.
This study characterizes the unique structure of the exopolysaccharides, confirming their profound antioxidant and skin-protective biological functions. These properties are essential for formulations that aim to defend the skin from environmental stressors.
This paper establishes a direct mechanism for preserving the dermal matrix by showing that the EPS fraction inhibits MMP-1 activity. This supports the use of the extract in cosmetic products formulated to maintain skin firmness and reduce the visible effects of collagen and elastin degradation.
