Overview
Corchorus extract is derived from the leaves or stems of the Corchorus plant, a member of the Tiliaceae family. Traditionally used in Ayurveda and Chinese medicine, it is valued for its bioactive compounds, including flavonoids, polyphenols, and polysaccharides. Modern applications span cosmetics, nutraceuticals, and functional foods due to its antioxidant and anti-inflammatory effects. The extract is typically produced through solvent extraction or supercritical CO2 methods, ensuring preservation of its active constituents. Its versatility and natural origin make it a popular choice for industries seeking plant-based alternatives to synthetic additives.
Physical and Chemical Properties
Corchorus extract appears as a brown liquid or powder, depending on the concentration and drying process. It is soluble in water and ethanol, facilitating its incorporation into aqueous or alcoholic formulations. The extract’s density ranges from 1.0 to 1.2 g/cm³ for liquid forms. Key bioactive components include quercetin, kaempferol, and chlorogenic acid, which contribute to its antioxidant capacity (measured via ORAC assays). The absence of a defined CAS number or molecular formula reflects its complex, multi-constituent nature as a plant extract.
Main Applications
In cosmetics, Corchorus extract is used in anti-aging serums and moisturizers for its ability to neutralize free radicals and soothe skin irritation. Its polyphenols also enhance product stability by preventing oxidative degradation. In the food industry, it serves as a natural preservative or functional ingredient in health beverages and supplements. Traditional medicine systems employ it for its purported benefits in managing inflammation and supporting digestive health.
Safety and Storage
Corchorus extract is generally safe for topical and oral use when processed under Good Manufacturing Practices (GMP). However, allergenicity tests are recommended for sensitive individuals. Storage in amber bottles at temperatures below 25°C (77°F) prevents degradation of heat-sensitive compounds. Regulatory compliance varies by region: In the EU, it may fall under the CosIng database for cosmetic use, while the FDA’s GRAS designation applies to food applications in the U.S.
B2B Procurement Guide
Buyers should prioritize suppliers providing third-party lab reports detailing bioactive content (e.g., flavonoid concentration) and absence of heavy metals/pesticides. Organic certification (e.g., USDA, Ecocert) adds value for eco-conscious brands. Negotiate bulk pricing for orders above 100 kg, and request samples to assess compatibility with your formulation. Leading sourcing regions include India, China, and Southeast Asia, where Corchorus is cultivated extensively.
