Product Overview
Lanolin, anhydrous LR is a highly refined, water-free derivative of sheep’s wool wax, processed to remove moisture and impurities for consistent laboratory performance. This laboratory-grade lanolin retains its natural emulsifying properties, making it an excellent medium for formulations requiring moisture retention, barrier protection, or solvent compatibility. Its semi-solid wax form ensures easy handling while maintaining stability across a range of temperatures. The LR grade confirms its suitability for general lab applications where purity and reproducibility are critical. Unlike hydrated lanolin, the anhydrous variant eliminates water content, reducing microbial growth risk and extending shelf life. Its non-irritating, biocompatible nature also makes it a preferred choice in applications involving skin or tissue contact. The product undergoes stringent quality checks to ensure batch-to-batch uniformity, with a typical melting point range of 38–44°C. Researchers value its ability to dissolve hydrophobic compounds while providing a protective, occlusive layer in experimental setups.
FAQs
1. What is the difference between anhydrous lanolin and regular lanolin?
Anhydrous lanolin is processed to remove all water content, typically containing less than 0.25% moisture, whereas regular lanolin retains 25–30% water. This makes anhydrous lanolin more stable, less prone to microbial contamination, and better suited for water-sensitive applications.
2. Can this lanolin be used in formulations requiring high-temperature stability?
Yes, anhydrous lanolin LR remains stable up to its melting point (38–44°C) and can withstand moderate heating without degradation. However, prolonged exposure to temperatures above 60°C may alter its viscosity or emulsifying properties.
3. Is this product compatible with organic solvents like ethanol or acetone?
Lanolin is partially soluble in ethanol but dissolves more readily in nonpolar solvents like chloroform or ether. For acetone, expect limited solubility; pre-testing is recommended for specific solvent ratios.
4. How should anhydrous lanolin be stored to maintain its properties?
Store in a tightly sealed container at room temperature (15–25°C), away from direct sunlight and moisture. Avoid refrigeration, as temperature fluctuations can cause separation or texture changes.
5. Does this lanolin contain any additives or preservatives?
No, this LR-grade anhydrous lanolin is free from added preservatives, fragrances, or stabilizers. It is pure wool wax, processed only to remove water and impurities.
