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.
