Porphyridium Cruentum ●
TL;DR. This ingredient is mainly used as a skin-conditioning and moisturizing film-former. Its polysaccharide-rich fraction helps improve slip, reduce water loss feel, and support a smoother skin surface in aqueous formulas.
What does Porphyridium Cruentum do in a cosmetic formula?
This ingredient is mainly used as a skin-conditioning and moisturizing film-former. Its polysaccharide-rich fraction helps improve slip, reduce water loss feel, and support a smoother skin surface in aqueous formulas.
Is Porphyridium Cruentum clean?
It is generally well accepted in clean-beauty frameworks, with low irritation potential and no common restricted-list issue. The main review points are the preservative system and any extraction residues in the supplied material.
Is Porphyridium Cruentum sustainable?
This material is typically sourced from cultivated photosynthetic marine biomass, which can use non-arable land and saline water. Its polysaccharide components are expected to be biodegradable, while the footprint depends on cultivation, concentration, and drying energy.
Is Porphyridium Cruentum COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic standards when produced from non-GMO biomass using allowed physical or biotechnology processes and approved solvents or preservatives. It fits Green Chemistry well when water-based extraction and low-energy concentration are used, with energy demand as the main caveat.
How does Porphyridium Cruentum work chemically?
The active fraction is rich in high-molecular-weight sulfated heteropolysaccharides containing uronic acids and neutral sugars, with minor proteins, minerals, and pigment fractions depending on processing. Supplier extracts are commonly used around 0.1 to 5%, are usually water-dispersible, and need compatible preservation in aqueous systems.
