Overview
Liquid rose extract is a natural concentrate obtained through solvent extraction or steam distillation of rose petals, primarily from Rosa damascena or Rosa centifolia. It contains volatile compounds like citronellol, geraniol, and phenylethyl alcohol, which contribute to its distinctive aroma and therapeutic benefits. The extract is prized in industries ranging from cosmetics to food for its fragrance, antioxidant properties, and skin-conditioning effects. Its versatility makes it a staple in formulations for perfumes, lotions, and even gourmet flavorings.
Physical and Chemical Properties
The extract typically appears as a reddish liquid with a strong floral scent. Its solubility in both water and organic solvents like ethanol allows for flexible formulation in various products. Key components include terpenes, flavonoids, and tannins, which provide antioxidant and anti-inflammatory effects. Density and viscosity vary slightly depending on the concentration and extraction method. The pH is usually mildly acidic (around 5.5-6.5), making it compatible with skin-care products. Stability is high when stored properly, though exposure to heat or light can degrade active compounds.
Main Applications
In cosmetics, liquid rose extract is used in toners, serums, and creams for its hydrating and anti-aging properties. Its antimicrobial effects also make it suitable for acne treatments. Perfumeries value it as a middle note in floral fragrances. The food industry employs it as a natural flavoring in desserts, beverages, and Middle Eastern dishes. Aromatherapists utilize its calming scent in diffusers and massage oils. Emerging applications include herbal medicines for stress relief and digestive aids.
Safety and Storage
While generally non-toxic, undiluted extract may cause skin irritation in sensitive individuals. Patch testing is recommended before widespread topical use. Ingestion should follow food-grade specifications and dosages. Storage requires airtight containers away from light and heat to preserve volatile compounds. Shelf life is typically 1-2 years when stored correctly. Suppliers often add natural preservatives like vitamin E to extend stability.
B2B Procurement Guide
Bulk buyers should prioritize suppliers offering certificates of analysis (CoA) for purity and solvent residues. Organic or wild-crafted sourcing ensures higher quality. Extraction methods like CO2 supercritical extraction yield cleaner products but are costlier. Negotiate pricing based on volume, with discounts common for orders exceeding 100 liters. Sample testing for scent profile and efficacy is advised before large purchases. Reliable suppliers often provide technical support for formulation integration.
