Rosemary antioxidant CO2 extract
Description
Rosemary CO2 Extract – Standardized Antioxidant Concentrate
Rosemary CO2 Antioxidant Extract is a concentrated ingredient obtained through eco-friendly supercritical carbon dioxide (CO2) extraction technology from rosemary leaves. Standardized in specific compounds, this extract excels through a high content of bioactive phenolic diterpenes. In cosmetic formulation, it serves the role of protecting plant oils, essential oils, and the lipid phase of preparations against oxidation and rancidity.
Ingredients (INCI): Helianthus Annuus Seed Oil, Rosmarinus Officinalis Leaf Extract.
Characteristics
- Appearance: Viscous, cloudy brown liquid with a characteristic odor
- Method of Extraction: Supercritical extraction with natural CO2 (free of inorganic salts, heavy metals, and microorganisms).
- Quality: 100% natural product, ECOCERT approved by the supplier
- Solubility: Soluble in the oil phase / lipophilic (insoluble in water).
- Recommended Dosage: 0.05% - 0.4%
Properties and Benefits
- Lipid Phase Stabilizer: Effectively prevents oxidation of unsaturated fatty acids, vegetable butters, and carotenoids, significantly extending the shelf life of cosmetic formulations without requiring synthetic antioxidants (BHT, BHA).
- Cutaneous Antioxidant Protection: The carnosic acid in its composition reduces oxidation of natural surface skin lipids induced by UV radiation and pollution.
- Cosmetic Active: Contains compounds with soothing and purifying action for the skin and scalp.
Applications
- Stabilization of oxidation-sensitive vegetable oils.
- Anhydrous facial serums and oils.
- Day/night creams, lotions, and emulsions (added to protect the oil phase).
- Balms, body butters, ointments, and sun care formulations (Sun Care & After-Sun).
- Artisanal natural soaps.
Formulation Guide
- Working Procedure: The extract has high viscosity and may settle slightly in the bottle; shake before use. It may solidify if stored in a colder environment; therefore, gently warm it to fluidify and homogenize.
- Incorporation: Can be added directly to oxidation-sensitive vegetable oils. In formulas containing an oil phase, it is generally added at the end of preparation, but it tolerates short-term heating.
- Dosing Precision: Being a highly potent active concentrate, a small addition is sufficient, generally 0.05% - 0.2%, which is approximately 1-6 drops per 100g of preparation.
Frequently Asked Questions (FAQ)
How does Rosemary CO2 Antioxidant Extract differ from Rosemary Essential Oil?
Rosemary essential oil is obtained through steam distillation and contains primarily volatile aromatic molecules (cineole, pinene, camphor), having a strong scent and an olfactive, aromatherapeutic role. Rosemary CO2 extract is obtained through selective supercritical extraction, containing large non-volatile molecules (carnosic acid, carnosol) that exhibit exceptional anti-rancidity antioxidant potency.
Usage Safety and Storage
Profile: Well-tolerated product within recommended cosmetic dosages. As a concentrated extract intended for formulation, it should not be applied pure or undiluted directly to the skin.
Precautions: For external cosmetic use only. Keep out of reach of children. Avoid direct contact with eyes in pure state.
Storage: In a closed container, in a dry and cool place, protected from light.
