Explore our premium portfolio of high-purity, standardized plant extracts designed for the global food, cosmetic, and nutraceutical industries.
Carnosic Acid (CAS No. 3650-30-0) is a naturally occurring benzenediol abietane diterpene found abundantly in Rosemary (Rosmarinus officinalis) and common sage (Salvia officinalis). As a primary lipophilic antioxidant, it functions as a highly efficient scavenger of singlet oxygen, hydroxyl radicals, and lipid peroxyl radicals. Unlike synthetic alternatives, Carnosic Acid features a unique thermal stability and fat-solubility profile, making it the premier option for protecting oils, fats, foods, and cosmetic formulations from oxidative degradation.
By implementing a strategic, multi-phase free radical termination mechanism, Carnosic Acid Powder prevents the onset of rancidity in food matrices and stabilizes lipid structures in dermal formulations. Its high efficacy at low concentrations makes it a cost-effective and clean-label compliant solution for global industries seeking to phase out synthetic preservatives like BHT, BHA, and TBHQ.

The international phytochemical market is witnessing a structural shift toward clean-label and natural preservation technologies. B2B buyers and manufacturers are scaling their procurement of rosemary-derived bioactive components due to changing consumer habits and tightening regulatory frameworks globally.
Regulatory bans and public resistance against synthetic compounds like TBHQ, BHA, and BHT have driven food processors and pet food manufacturers to seek highly stable natural lipophilic antioxidants to preserve shelf life.
Natural cosmetics require stabilization without synthetic parabens or chemical stabilizers. Carnosic Acid serves dual functions: providing anti-aging properties while maintaining oil phase stability.
Procurement departments demand certified supply lines. Verification of pesticide residues, heavy metals, PAHs, and compliance with EU/FDA regulations is paramount for import clearance.
As a leading exporter, Andy Biotech leverages state-of-the-art Factory 4.0 paradigms to optimize the phytochemical extraction process. By utilizing advanced automated facilities in Shaanxi province, we ensure high-yield processing of Rosmarinus officinalis leaves under tightly regulated environmental conditions.
Our extraction lines implement Supercritical CO2 Fluid Extraction alongside specialized green solvent-based recovery setups. This ensures the preservation of structural integrity of delicate diterpenes, eliminating the risk of thermal degradation and guaranteeing solvent residue levels well below standard EU and US pharmacopoeia limits.
Through vertically integrated manufacturing, we bypass intermediary logistics and maintain direct-from-origin pricing. This guarantees high cost-efficiency, steady volume commitments, and minimal batch-to-batch variation, even amidst volatile global supply chain dynamics.
Carnosic Acid Powder is highly versatile, serving as a functional ingredient and clean-label preservative across several key industries:
Preserves fats and oils in premium dry kibbles and treats, preventing lipid oxidation and maintaining palatability over extended storage.
Stabilizes unsaturated vegetable oils, frying fats, and animal lipids (lard, tallow, fish oil) against high-temperature degradation and rancidity.
Protects lipophilic actives and essential oils in creams, lotions, and balms. Offers skin-soothing, anti-pollution, and anti-aging properties.
Used in dietary supplement formulations targeting cognitive health, cellular protection, and inflammatory response regulation.

Andy was born in a small village close to Hanjiang River in Hanzhong Shaanxi province, China. Thirty years ago, when she was still a little child, she caught a cold, but the medical services were not available unless the family crossed over high mountains to find a hospital. Thus, Andy's grandfather first used Echinacea leaves soaked in water for her treatment, then he dug Echinacea root and shredded it into pulp, squeezing the liquid for Andy to drink one spoon every two hours. Andy recovered after this treatment.
As a child, Andy watched her grandfather harness the healing power of plants in his humble garden. His ancient herbal remedies were not just treatments; they were magic. That early wonder blossomed into a profound passion for plant extracts and a deep respect for nature’s wisdom. From that time on, little Andy swore that she would help to spread all herbs all over the world to give benefit to more people.
This personal journey is the heart of Andy Biotech. It’s why Andy Biotech is dedicated to researching and delivering the purest, most effective botanical solutions for modern wellness. Andy’s lifelong vow is to honor that tradition by innovating for a healthier future, empowering lives through the timeless power of plants.
Essential technical and procurement details regarding Carnosic Acid Powder and our export capabilities.
We supply standardized Carnosic Acid Powder with concentrations ranging from 5% up to 95% measured by HPLC. For general food and feed applications, 5% to 20% concentrations are widely requested, whereas higher concentrations (60% to 95%) are typically procured for pharmaceutical and cosmetic applications requiring minimal additive volume.
Carnosic Acid is a highly effective lipophilic free-radical scavenger that excels in preventing thermal degradation. Comparative studies indicate that at equivalent active concentrations, Carnosic Acid performs comparably to or outperforms TBHQ, and shows significantly better performance than BHA/BHT in high-fat food formulations and pet food preservation, without carrying safety or clean-label concerns.
No, natural Carnosic Acid is inherently lipophilic (oil-soluble). It is highly soluble in lipids, fats, vegetable oils, organic solvents, and ethanol. For formulations requiring water solubility, we offer modified formulation options, including microencapsulated or emulsified variations, which disperse evenly in aqueous systems.
Our raw materials are sourced from controlled rosemary plantations under strict agricultural monitoring. Our quality assurance program verifies each batch against USP, EP, and FDA standards. The Supercritical CO2 extraction process leaves no organic solvent residues, and third-party laboratory analysis confirms that pesticide residues, heavy metals, and PAHs remain below detectable limits.
Our Carnosic Acid Powder has a standard shelf life of 24 months when stored in its original, unopened packaging in a cool, dry place. Because it is highly reactive with oxygen, it is packaged in nitrogen-sealed foil bags. Keeping it protected from direct sunlight, high heat, and moisture is essential to prevent degradation of the active diterpenes.
