Description

Ethyl Rosmarinate is a high-purity ester derivative of rosmarinic acid, valued for its enhanced stability and bioavailability compared to its parent compound. This ingredient is critical for formulators seeking powerful antioxidant and anti-inflammatory properties in advanced applications. It serves as a key functional ingredient for leading manufacturers in the cosmetics, nutraceutical, and pharmaceutical industries.

Application

• Cosmetic & Skincare Formulations: Used as a potent active ingredient in anti-aging serums, creams, and lotions for its antioxidant and skin-brightening properties.
• Dietary Supplements & Nutraceuticals: Incorporated into capsules and tablets for its systemic anti-inflammatory and neuroprotective health benefits.
• Functional Food & Beverages: Serves as a natural preservative and health-enhancing additive in premium food and drink products.
• Pharmaceutical Intermediates: Acts as a key chiral building block or active pharmaceutical ingredient (API) in the synthesis of more complex therapeutic agents.
• Advanced Biomedical Research: Utilized in in vitro and in vivo studies to investigate mechanisms related to oxidative stress and inflammation.
• Preservative Systems: Enhances the shelf-life and stability of natural product formulations by inhibiting lipid peroxidation.
