2. What Is Rosemary Extract?
Rosemary Extract is derived from the dried leaves of Rosmarinus officinalis L., a perennial aromatic herb traditionally valued for its preservative and antioxidant properties. Modern extraction and standardization processes concentrate key phenolic diterpenes, primarily Carnosic Acid and Carnosol, which are responsible for its oxidative stability in formulations.
In industrial applications, Rosemary Extract is widely recognized as a plant-based alternative to synthetic antioxidants, supporting product shelf life and formulation integrity without artificial additives.

4. Primary Functional Mechanisms & Benefits (Non-Medical)
The following descriptions focus on functional and formulation properties, not disease treatment.
-
Antioxidant Activity
Carnosic Acid functions as a lipid-soluble antioxidant, helping protect oils and active ingredients from oxidative degradation. -
Formulation Stability Support
Commonly used to enhance shelf stability in emulsions, oils, and lipid-rich systems. -
Clean-Label Ingredient Role
Suitable for formulations seeking natural, plant-derived antioxidant systems. -
Sensory Protection
Helps maintain color and odor stability in food and cosmetic applications.
5. Traditional & Historical Use (Contextual Reference)
Rosemary has been traditionally used in food preservation and herbal preparations across Mediterranean cultures. Modern industrial use focuses on standardized extracts, produced under controlled conditions to ensure reproducibility and safety.
6. Usage Guidelines & Formulation Considerations
Recommended Industrial Dosage (Typical Reference Ranges)
