Rosemary CO2 Extract as a Natural Preservative and Skin Care Ingredient
Rosemary CO2 Extract BIO in a 5 g package suits home formulators and small trial batches where precise dosing matters and no raw material should go to waste. It is produced through supercritical carbon dioxide extraction, a method that preserves the maximum concentration of active rosemary compounds without solvents or excessive heat exposure. This product belongs to the CO2 Extracts category, known for highly concentrated, cost-effective botanical actives. Global demand for rosemary CO2 extract extends well beyond cosmetics into food production, where it functions as a natural antioxidant that stabilizes vegetable oils, fats, and meat products, replacing synthetic preservatives. Thanks to its content of carnosic acid and carnosol, the extract effectively slows lipid oxidation, extending the shelf life of finished formulations.
In skin and hair care, rosemary extract is widely used in scalp treatments since it supports healthier-looking hair follicles and gives hair a well-groomed appearance, as well as in creams for stressed skin due to its toning and antioxidant properties. A typical usage rate ranges from 0.1 to 0.5 percent of the total formula weight, added at the cooling stage below 40 degrees Celsius to protect volatile compounds. In perfumery, rosemary is valued for its recognizable herbaceous, camphor-like character that blends well with woody and citrus notes. In household chemistry, small amounts are added to wood care products for their natural antioxidant protection.
Rosemary extract pairs well with other CO2 concentrates, such as Carrot CO2 extract BIO in jojoba for nourishing formulas targeting dry skin, CO2 extract Arnica BIO in post-activity body care, and Licorice CO2 Extract for soothing, softening blends. When added to oil-based bases, rosemary extract effectively extends their shelf life through its own antioxidant action, which is particularly valuable for vegetable oils prone to rancidity. Some soap makers add it to fat blends to slow oxidation, though this represents only one narrow use among many broader applications.
Store the extract in a tightly sealed container, in a cool, dark place away from direct sunlight and heat sources, ideally between 4 and 20 degrees Celsius. Once opened, use the content within a few months to preserve its full antioxidant potential.
