Rosmarinic Acid 2% Acid Extract
Overview
Rosmarinic acid is a naturally occurring phenolic compound found in rosemary, basil, and other plants. The 2% extract form is a concentrated version, commonly used in various industries due to its potent bioactive properties. It is known for its antioxidant and anti-inflammatory effects, making it valuable in health and cosmetic applications. The extraction process typically involves solvent extraction from rosemary leaves, followed by purification to achieve the desired concentration. The 2% extract is standardized to ensure consistent quality and efficacy, making it a reliable ingredient for manufacturers.
Physical and Chemical Properties
Rosmarinic acid 2% extract appears as a light yellow to brown powder, soluble in water and organic solvents like ethanol and methanol. Its molecular structure includes two phenolic rings, contributing to its strong antioxidant activity. The compound is stable under normal storage conditions but may degrade when exposed to excessive heat or light. With a melting point of approximately 171-175°C, rosmarinic acid exhibits moderate thermal stability. Its solubility profile allows for versatile formulation in liquid and solid products, enhancing its applicability across different industries.
Main Applications
In the cosmetic industry, rosmarinic acid 2% extract is used in anti-aging creams, sunscreens, and serums due to its ability to neutralize free radicals and reduce skin inflammation. It also finds application in hair care products to promote scalp health. The pharmaceutical sector utilizes this extract for its potential to support cardiovascular health and reduce oxidative stress. Additionally, it is incorporated into dietary supplements and functional foods as a natural preservative and health booster.
Safety and Storage
Rosmarinic acid 2% extract is generally regarded as safe for topical and oral use at recommended concentrations. However, prolonged exposure to high concentrations may cause skin irritation or allergic reactions in sensitive individuals. Proper storage involves keeping the extract in a cool, dry place, away from direct sunlight and moisture. Sealed containers are recommended to prevent contamination and degradation. Always follow manufacturer guidelines for handling and disposal.
B2B Procurement Guide
When procuring rosmarinic acid 2% extract, prioritize suppliers with certifications such as ISO or GMP to ensure quality and compliance. Request detailed product specifications, including purity, solvent residues, and microbial limits. Bulk purchases may offer cost advantages, but verify storage capabilities to maintain product integrity. Establish long-term relationships with reliable suppliers to ensure consistent supply and quality. Consider testing samples before large-scale procurement to confirm suitability for your application.
