Sourcing and specification details
Evening Primrose CO2 Extract is produced in England from Oenothera biennis seeds via supercritical carbon dioxide extraction. CO2 Extracts section lists this oily liquid in 5 g packs free of solvent residues and heavy metals. International buyers receive consistent quality suitable for scale-up from lab to production line. Primrose Evening CO2 Extract 100 g supports initial formulation trials before larger commitments.
Composition for formulation work
The extract contains gamma-linolenic acid, tocopherol, quercetin, polysaccharides and trace minerals. These elements integrate into lipid phases to support emulsion stability and oxidative resistance in finished goods. Cosmetic labs and supplement manufacturers value the absence of chemical solvents, enabling clean-label positioning across global markets.
Recommended input levels
Dosage ranges from 0,05-0,1 % in day creams to 1,5 % in body massage gels. Add to the oil phase below 40 °C. Hair masks receive 0,5-1 %, after-shave products 0,05-0,5 %. Solubility is limited to fats, therefore pre-dispersion in carrier oils is advised for uniform distribution.
Role in dietary supplements and food manufacturing
Supplement producers and confectionery factories source this botanical raw material for functional blends, beverages and chocolate masses. Primrose Evening CO2 Extract 1 kg meets the needs of both private formulators and large-scale plants requiring plant-derived fatty acids and antioxidants. This supports efficient integration into existing production lines without process modifications.
Sample serum formulation

Storage guidelines
Keep tightly closed in a cool dark place until December 2028. Protect from heat and direct sunlight to maintain fatty acid integrity throughout the declared shelf life.
