Product Introduction
Carnosic Acid is a high-value natural active antioxidant extracted and purified from Rosmarinus officinalis (Rosemary) and Salvia officinalis (Sage). It features excellent solubility and stable physical and chemical properties. It maintains high stability under neutral and alkaline environments, while it is prone to decomposition under acidic conditions.
With natural origin, high safety and powerful antioxidant activity, Carnosic Acid is widely applied in food preservation, flavor modulation, skincare anti-aging and biomedical research. We supply multi-specification products to meet diverse industrial demands: low content (5%-60%) presents fine yellow powder, while high-purity 98% grade is uniform white/beige powder with superior activity and purity.
Various specifications are available, low content 5%-60% is yellow powder, high content 98% is white powder.

Core Functions & Efficacy
As a multifunctional natural active ingredient, Carnosic Acid integrates antioxidant, antibacterial, anti-inflammatory and protective effects, with wide application value in food, cosmetics and biomedicine:
1. Powerful Antioxidant Activity
It efficiently neutralizes free radicals in the body, reduces cell and tissue damage caused by oxidative stress, inhibits lipid oxidation, and exerts long-lasting and stable antioxidant protection. It is far safer and more effective than many synthetic antioxidants.
2. Broad-Spectrum Antibacterial & Preservative Effect
It can effectively inhibit or kill a variety of bacteria and fungi, especially targeting common food pathogenic bacteria. It prevents food spoilage and mildew, inhibits microbial reproduction, and realizes natural fresh-keeping and shelf-life extension.
3. Nervous System Protection
Carnosic Acid protects nerve cells from oxidative stress and inflammatory damage, improves the microenvironment of nerve tissues, and has potential preventive and auxiliary therapeutic effects on various neurological diseases.
4. Intestinal Health Regulation
Scientific studies have verified that it can effectively relieve colitis symptoms. It repairs intestinal inflammation by regulating gut microbiome metabolites and inhibiting excessive inflammatory response, improving overall intestinal microecological health.
It significantly reduces renal damage, oxidative stress and renal inflammatory reactions. As a natural active substance, it has great development potential for the auxiliary treatment of diabetic nephropathy and other renal lesions.
Wide Application Fields
1. Food Industry (Natural Antioxidant & Preservative)
It is widely incorporated into meat products, edible oils, condiments, biscuits, fruit and vegetable products to inhibit lipid oxidation, prevent food deterioration, maintain food freshness and effectively extend product shelf life.
2. Food Flavor Additive
With a unique natural herbal aroma, it can be applied in beverages, chewing gum, baked goods and other products to enrich flavors and enhance taste hierarchy.
3. Cosmetic & Skincare Industry
It resists free radical damage, relieves skin oxidative aging, fades fine lines and wrinkles, and improves skin dullness. It is widely added to anti-aging creams, serums, eye creams, facial masks and other functional skincare products.
Benefiting from excellent anti-UV and antioxidant properties, it helps resist ultraviolet radiation damage and reduce sunburn and photoaging, serving as an efficient natural additive for sunscreen products.
4. Natural Sunscreen Raw Material
5. Biomedical Research
It acts as a core raw material for the research and development of neuroprotective, anti-colitis and renal protective drugs, boasting broad prospects in biomedical applications.
