Overview
Alchemilla Extract is derived from the aerial parts of Alchemilla vulgaris, a perennial herb native to Europe and Asia. Traditionally used in folk medicine, it is now a key ingredient in modern skincare and therapeutic formulations due to its bioactive compounds. The extract is typically obtained through hydroalcoholic or water-based extraction, preserving its polyphenol content. Its versatility makes it suitable for both cosmetic and pharmaceutical industries, often labeled as a 'natural active' in product formulations.
Physical and Chemical Properties
The extract is characterized by its high tannin content (up to 8%), which contributes to its astringent and anti-inflammatory effects. Flavonoids like quercetin and kaempferol provide antioxidant benefits. Its liquid form is typically viscous with a mild herbal odor, while the powdered variant is hygroscopic. Stability testing indicates a shelf life of 2-3 years when stored properly. The extract's pH ranges from 4.5 to 6.0, making it compatible with most cosmetic formulations.
Main Applications
In cosmetics, Alchemilla Extract is prized for its skin-tightening and redness-reducing properties. It is commonly formulated into toners, anti-aging serums, and post-treatment creams for sensitive skin. Pharmaceutical applications include wound-healing ointments and oral supplements for gastrointestinal health. Its antimicrobial properties also make it a candidate for natural preservative systems in clean-label products.
Safety and Storage
The extract is classified as non-toxic in standard cosmetic concentrations (0.5-5%). However, excessive use may cause dryness due to its astringency. For bulk storage, stainless steel or food-grade plastic containers are recommended. Liquid extracts should be protected from freezing, while powders require desiccant packs to prevent clumping. Industrial users should conduct stability tests under accelerated conditions to determine batch-specific requirements.
B2B Procurement Guide
When sourcing Alchemilla Extract, prioritize suppliers who provide certificates of analysis (COA) detailing polyphenol content and solvent residues. Organic and wildcrafted options command premium prices (20-30% higher). For large orders (100+ kg), negotiate tiered pricing and request pilot batches for compatibility testing. Consider extracts standardized to tannin content (e.g., 5% minimum) for consistent formulation performance. Shipping typically requires ambient temperature conditions without special hazardous material declarations.
