- Product Description
Premium Rosmarinus Leaf Extract Introduction
100% Natural, High-Potency Antioxidant Solution to Boost Product Efficacy & Stability
Rosmarinus Leaf Extract, derived from organically grown rosemary (Rosmarinus officinalis), is a powerful ingredient for enhancing skincare formulations. Shaanxi Hongda selects organic rosemary from prime growing regions, employing core "supercritical CO2 extraction + gradient solvent recovery" technology to ensure rosmarinic acid content remains between 5% and 95%. We have also completely resolved the common problems of "solvent residue" and "herbal odor" associated with natural extracts. This extract is an ideal choice for brands that prioritize pure beauty and clinical efficacy.
High-performance liquid chromatography (HPLC) analysis shows that its rosmarinic acid content is ≥20%, effectively combating free radicals, enhancing product stability, and strengthening anti-aging effects. Whether you are developing serums, creams, or sunscreens, this versatile Plant Extract formula can meet your various needs while complying with global organic standards.

Rosemary Extract Benefits
Strong antioxidant:
Rosemary extract has strong antioxidant properties, which can effectively remove "free radicals" that damage body cells, protect skin, blood vessels, etc., help you delay aging and stay young.
Protect skin health:
Rosmarinic acid powder can reduce the damage of ultraviolet rays to the skin, fight skin aging (wrinkles, sagging), and can brighten the skin tone in skin care products, making the skin look healthier and more radiant.
Eliminate inflammation:
Rosemary extract can reduce inflammation, reduce body swelling, and has a certain effect on arthritis.
Protect the brain:
Studies have found that pure natural rosemary extract may protect brain cells, help improve memory and concentration, and has a certain potential for preventing cognitive decline in the elderly (such as Alzheimer's disease).
Natural preservative:
Pure rosemary powder has a certain effect of inhibiting bacterial growth and is often used as a natural preservative for food to prevent food from rotting.
Applications
Age-Defying Serums
Blend at 0.5–2% to reduce wrinkle depth by 22% and boost elasticity in 4 weeks.Clean Beauty Preservatives
Replace parabens in organic creams—our extract meets ISO 17516 microbial limits at 3% concentration.Post-Sun Recovery
Enhances UV protection in SPF products while calming inflammation.
Production Process of Rosemary Extract
1. High-Pressure Air Classification and Countercurrent Ultrasonic Crushing of Raw Leaves: High-quality dried rosemary leaves free of pesticide residues are selected. Impurities such as mud and sand are removed using a high-pressure cyclone separator, followed by physical and mechanical crushing at low and normal temperatures to break down plant cell walls and fully expose polyphenols and diterpenoids.
2. Polar-Directed Fractional Solvent Extraction: We use either pure water (for extracting rosmarinic acid) or food-grade supercritical carbon dioxide/low-concentration ethyl acetate (for extracting oxalic acid) in a multi-stage countercurrent circulation extraction process.
3. High-Vacuum Gravitational Molecular Distillation and Removal of Harmful Essential Oils: The concentrated crude extract is fed into a two-stage short-path molecular distillation apparatus. Under an ultra-high vacuum of 0.1 mbar, the boiling point difference is used to instantaneously evaporate volatile essential oil components such as camphor and eucalyptol, which have a pungent medicinal odor, thus completely deodorizing the bulk product.
4. Macroporous Special Polar Chromatography Decolorization and Resin Purification: The deodorized mother liquor passes through a specially modified hydrophobic/hydrophilic chromatographic resin bed. Utilizing selective adsorption, it physically intercepts dark green chlorophyll and high-molecular-weight tannins, transforming the color of the eluted target filtrate from dark green to a clean light yellow to pure white.
5. Falling Film Secondary Ultra-Low Temperature Negative Pressure Concentration: The refined eluent is pumped into a fully enclosed multi-effect falling film evaporator. The temperature of the vacuum heating surface is strictly controlled to not exceed 50℃, ensuring that residual extraction media evaporates completely within tens of seconds, while simultaneously preventing thermal degradation of oxalic acid during concentration.
6. Aseptic Airflow Cold Drying Atomization and Anti-static Nitrogen-Filled Seamless Packaging: The concentrated paste is homogenized under high pressure and then enters a closed spray drying tower or vacuum belt dryer. Under the protection of dry air, it is atomized into highly loose particles. The output is directly connected to a closed packaging line with a relative humidity of less than 30% and under nitrogen protection.
The essential differences between rosmarinic acid, sauropic acid, and ursolic acid
Rosmarinic Acid | Carnosic Acid | Ursolic Acid | |
Chemical classification and structure | It belongs to the water-soluble phenolic acid class of compounds, containing multiple hydrophilic phenolic hydroxyl groups within its molecule. | It belongs to the lipid-soluble diterpenoid phenolic class of compounds, possessing an extremely strong hydrophobic carbon skeleton. | It belongs to the pentacyclic triterpenoid class of compounds, exhibiting both weak hydrophilicity and hydrophobicity. |
Physical solubility property | It is 100% readily soluble in water, pure ethanol, and ethylene glycol, but completely insoluble in oils and fats. | 10% readily soluble in animal and vegetable oils and organic solvents; completely insoluble in water. | Insoluble in water, slightly soluble in hot ethanol, and can be dispersed in specific emulsion systems. |
Applications | Applications include: aqueous phase antioxidant, anti-discoloration agent in water-based functional beverages, high-end skin care toners, and natural water-based preservatives. | Applications include: anti-rancidity of whole fats and oils, preservation of pet food, fresh meat products, and shelf-life preservation of high-fat nut oils. | Skin barrier repair and anti-inflammatory, high-end anti-aging skin care products, and dietary supplements for myofiber protection. |

FAQs
Q: How to choose between sagelic acid and rosmarinic acid?
A: If your base is oil or cream (such as cooking oil, meat), please choose the fat-soluble sagelic acid; if your base is a water-based product (such as beverages, serums, capsules), please choose the water-soluble rosmarinic acid.
Q: Will the color and odor of rosemary extract affect my final product?
A: Hongda uses a patented decolorization and deodorization technology to reduce the 95% purity of sagelic acid to near-odorless and extremely light color, minimizing the impact on the appearance and sensory characteristics of the formulation.
Q: How does Rosmarinus Leaf Extract improve formulation stability?
A: Its natural polyphenols inhibit lipid oxidation, reducing the need for synthetic preservatives.
Q: Is it compatible with vitamin C?
A: Yes! Our extract enhances vitamin C’s photoprotection while maintaining pH stability.
