Natural Rosemary Extract

Natural Rosemary Extract: Premium Quality from Shaanxi Hongda Phytochemistry Co., Ltd.

To preserve bioactive components, Shaanxi Hongda Phytochemistry Co., Ltd. selects carefully chosen rosemary (Rosmarinus officinalis L.) leaves to Natural Rosemary Extract. After extraction with methanol or ethanol, 30% caryopsisic acid, 16% caryopsisol, and 15% rosmarinic acid are obtained. The rosemary series supplied by Shaanxi Hongda is not merely a simple Plant Extraction, but a high-quality raw material achieved through molecular distillation and supercritical CO2 extraction technology. Our core process lies in "extreme decolorization and deodorization," ensuring extremely high oxidation-induced period (OSI) extension without affecting the transparency of the oils or the fragrance of skincare products. This is not just an antioxidant; it is a high-level biological barrier providing your end products with the core logic of "extended shelf life and maintained flavor stability."

Why do our rosemary extract formulators love it?

1. Precise Oil-Water Targeting:

Carnosic Acid 5%-95%: Strongly oil-soluble, designed for edible oils, meat products, and pet treats; extremely resistant to pyrolysis.

Rosmarinic Acid 2.5%-98%: Excellent water solubility, customized for functional beverages, cosmeceuticals, and anti-blue light products.

2. Ultimate Physical and Sensory Purification:

Through specific microencapsulation or activated carbon adsorption processes, we have solved the industry pain points of rosemary extract being "green, sticky, and bitter." Our powder is a very light beige to white color, and after dissolving, it has extremely high clarity, suitable for any high-end transparent system.

3. Ultimate Safety Standards:

Hongda's factory complies with the latest EU (EC) 1881/2006 directive. Regarding solvent residue, we have achieved hexane-free and acetone-free green extraction, with heavy metal Pb/As levels controlled below 0.1 ppm, meeting the audit requirements of top pharmaceutical companies.

4. Quality Assurance:

Quality assurance comes from FDA, HACCP, and ISO 22000 certifications, as well as batch-specific testing (DPPH free radical scavenging assay) and a complete Certificate of Analysis (COA).
