Our product has a high purity level, typically above 98% as determined by high - performance liquid chromatography (HPLC). This ensures its effectiveness in various applications.
Rosmarinic acid has a wide range of uses due to its excellent biological activities.
**Antioxidant**: It can scavenge free radicals in the body, protecting cells from oxidative damage. This property makes it valuable in the cosmetic industry, where it can be used in anti - aging products to reduce the appearance of wrinkles and improve skin elasticity. In the food industry, it can prevent the oxidation of fats and oils, extending the shelf - life of food products.
**Anti - inflammatory**: Rosmarinic acid can inhibit the production of inflammatory mediators. It is used in the pharmaceutical field for the treatment of inflammatory diseases such as arthritis and dermatitis. In the nutraceutical industry, it can be formulated into dietary supplements to support a healthy inflammatory response.
**Antimicrobial**: It has antibacterial and antifungal properties. In the agricultural sector, it can be used as a natural preservative to prevent the growth of microorganisms in livestock feed. In the food industry, it can be used to control the growth of harmful bacteria in food products.
**Cosmetic Application**: When used in cosmetics, it can be added to creams, lotions, and serums. First, heat the oil and water phases of the cosmetic formulation separately. Then, dissolve the rosmarinic acid in a small amount of ethanol or propylene glycol. Add the dissolved rosmarinic acid to the water phase under stirring. Finally, combine the oil and water phases and homogenize the mixture.
**Pharmaceutical Use**: For pharmaceutical preparations, it can be formulated into tablets, capsules, or injectable solutions under strict pharmaceutical manufacturing standards. The dosage should be determined according to the specific disease and the patient's condition, usually under the guidance of a medical professional.
**Food Industry**: In the food industry, it can be added directly to food products during the production process. The amount added should comply with relevant food safety regulations. For example, in oil - containing food products, it can be added at a concentration of 0.01% - 0.1% to prevent oxidation.
**Cosmetic Case**: A well - known cosmetic brand added our high - quality rosmarinic acid to their anti - aging serum. After a three - month clinical trial with 100 volunteers aged 35 - 50, it was found that 80% of the volunteers reported a visible reduction in fine lines and improved skin texture. The brand's sales of this serum increased by 30% within six months after the product launch.
**Pharmaceutical Case**: A pharmaceutical company developed a new anti - arthritis drug using rosmarinic acid as the main active ingredient. In a clinical trial involving 200 arthritis patients, after three months of treatment, 70% of the patients reported a significant reduction in pain and inflammation. The drug has since been approved by the relevant regulatory authorities and is being sold in the market.
**Food Industry Case**: A food processing company added rosmarinic acid to their fried snacks to prevent oil oxidation. They compared the shelf - life of the snacks with and without rosmarinic acid. The snacks with rosmarinic acid had a shelf - life that was extended by two months compared to the control group without rosmarinic acid. This not only reduced the company's production costs but also improved the quality and safety of their products.
