Building Long-Shelf-Life Formulas With Rosemary CO2 Extract
Rosemary CO2 extract in a 100 gram pack is suited for manufacturers, formulation labs and studios that need a steady supply of raw material without frequent reorders. This concentrated substance is obtained through low-temperature carbon dioxide extraction, a method that preserves the maximum level of active compounds naturally present in rosemary, particularly the antioxidant molecules carnosic acid and carnosol, along with aromatic components responsible for the herb's recognizable invigorating character. This extract belongs to the CO2 Extracts category, a group of concentrates valued for their high retention of natural antioxidants and minimal thermal degradation during processing.
The primary industrial use of rosemary CO2 extract is natural stabilization of oil and fat phases at production scale. It functions as a natural antioxidant that slows oxidation in vegetable and cosmetic oils, which is essential for cosmetic manufacturers producing creams, balms, serums and oil-based blends with extended shelf stability. In the food industry the same principle is applied to stabilize fats and oil-based products, where natural antioxidants are increasingly replacing synthetic preservatives. The extract is also used in hair and scalp care formulations, where it supports the condition of hair follicles and lends products a tonifying quality, as well as in fragrance and aromatic compositions thanks to its herbaceous, camphor-like profile.
In formulations, rosemary CO2 extract is introduced during the oil phase blending stage, at temperatures not exceeding 40-50 degrees Celsius, to avoid degrading its heat-sensitive antioxidant compounds. Recommended dosage typically ranges from 0.1 to 1 percent of total product mass depending on the desired concentration of active substances and the type of formulation - minimal levels are sufficient for antioxidant protection of an oil base, while higher levels are used when a pronounced tonifying effect is the goal in leave-on care products. The extract is compatible with vegetable oils, waxes, emulsifiers and most plant-based extracts, making it a flexible component in multi-ingredient formulas.
Store the extract in a tightly sealed container, in a cool dark place away from direct sunlight and heat sources, which helps preserve its antioxidant activity for the full shelf life. When building multi-component formulas, rosemary extract is frequently combined with other CO2 concentrates - for example with Rosemary CO2 Extract BIO to reinforce an organic-oriented product profile, with Amaranth CO2 Extract for nourishing compositions aimed at skin recovery, and with Juniper CO2 Extract for cleansing and toning formulas designed for problem-prone skin.
Stabilized Facial Oil Serum
Jojoba oil 400 g
Rosehip oil 300 g
Squalane 250 g
Rosemary CO2 extract 30 g
Vitamin E 20 g
Combine
jojoba oil, rosehip oil and squalane in a clean mixing vessel at room
temperature, stirring until fully blended. Warm the mixture gently to no more
than 40 degrees Celsius, then add the rosemary CO2 extract and vitamin E,
stirring slowly for several minutes until the extract is evenly dispersed
throughout the oil blend. Allow the serum to rest for a short period before
bottling into dark glass containers to protect it from light exposure during
storage.
