Blue-Green Algae Extract ●
TL;DR. This ingredient is primarily a skin-conditioning extract, used to add a hydrated feel and support antioxidant-style claims from its mix of polysaccharides, amino acids, minerals, and pigments.
What does Blue-Green Algae Extract do in a cosmetic formula?
This ingredient is primarily a skin-conditioning extract, used to add a hydrated feel and support antioxidant-style claims from its mix of polysaccharides, amino acids, minerals, and pigments.
Is Blue-Green Algae Extract clean?
From a clean-beauty perspective, it is generally acceptable when supplier testing verifies low microbial load, heavy metals, and absence of unwanted bloom-related metabolites. It is not a typical restricted-list ingredient, though complex natural extracts can be a sensitivity trigger for some users.
Is Blue-Green Algae Extract sustainable?
It can be sourced from renewable aquatic biomass and is expected to be biodegradable. The sustainability profile depends on controlled cultivation, responsible water use, and strong contaminant testing rather than poorly documented wild harvesting.
Is Blue-Green Algae Extract COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic when derived from allowed natural sources and processed with approved extraction methods and solvents. Its Green Chemistry fit is strongest when made with water or other permitted benign solvents, low-energy drying, and documented traceability.
How does Blue-Green Algae Extract work chemically?
It is a complex aqueous or hydro-glycolic extract of photosynthetic microbial biomass, so the active fraction is a mixture rather than a single molecule. Use levels are commonly low, often about 0.1–5% depending on supplier concentration, and it is usually added during cool-down with preservative support because heat, light, oxidation, and extreme pH can affect color and odor.
