what is lanolin?

What is lanolin? Lanolin( from Latin lana= wool, oleum= oil), also known as wool wax or wool grease, is a natural, complex fat secreted by the sebaceous glands of wool-bearing animals( primarily sheep). 

It is the material that garments sheep's wool, protecting them from the harsh environmental conditions of extreme cold, heat, and drier climates. Chemically, Lanolin is not a traditional fat( triglyceride). 

Instead, it is a wax ester—a unique matrix of long-chain fatty acids esterified with long-chain aliphatic alcohols and sterols( including cholesterol and lanosterol). 

This unique structure gives Lanolin an exceptional ability to absorb and retain water (up to 400% of its own weight), making it biologically similar to human skin lipids.

On Echemi, Lanolin is available in multiple grades, ranging from crude wool grease( for industrial use) to highly refined, hypoallergenic grades for premium skincare and pharmaceutical applications.

Barium Carbonate (BaCO₃): Properties, Production, Applications, and Safety

图片
  1. Introduction Barium Carbonate (BaCO₃) is an inorganic compound widely used in industries such as ceramics, glass, and chemicals. It is a white, odorless powder with limited solubility in water but soluble in acids. This article explores its properties, synthesis methods, applications, and safety measures in exhaustive detail. 2. Physical and Chemical Properties 2.1 Physical Properties Molecular Weight: 197.34 g/mol Appearance: White crystalline solid (rhombic or alpha form at room temperature) Density: 4.286 g/cm³ Melting Point: 811°C (decomposes to BaO + CO₂) Solubility: 0.002 g/100 mL (water, 20°C) Soluble in acids (e.g., HCl, HNO₃) 2.2 Chemical Properties Thermal Decomposition: BaCO3→ΔBaO+CO2↑ BaCO3ΔBaO+CO2↑ Reaction with Acids: BaCO3+2HCl→BaCl2+H2O+CO2↑ BaCO3+2HCl→BaCl2+H2O+CO2↑ Conversion to Barium Sulfate: BaCO3+H2SO4→BaSO4+H2O+CO2↑ BaCO3+H2SO4→BaSO4+H2O+CO2↑ 3. Production Methods 3.1 Carbonation Process Barium sulfide (BaS) solution is treated with CO₂: BaS+H2O+CO2→BaC...

Matrine  Sophora flavescens Chemical composition As early as the early 1930s, the Soviet Union began to study it abroad, and China began in 1972. The focus of research at home and abroad is on alkaloids. The alkaloids extracted, separated and identified from Sophora flavescens plants in China mainly include oxymatrine (C15H24N2O2), matrine (C15H24N2O), isomatrine (Iosmatrine, C15H24N2O), hydroxymatrine (sophor-anol), sophocarpine (C15H22N2O), N-oxysophocarpine (C15H22N2O2), sophoramine, sophoridine (Sophoridine, C15H24N2O), Aloperine, sparteine, N-methylcytisine, anagyrine, bap-iifoline, sophocarpine, d-matrine, d-isomatrine, d-oxymatrine, l-anagyrine, l-methyleytisine, l-baptifoline, kurarid-in, sophoranol (C15H24N2O2), sophoranhol N-oxide (C15H24N2O3), N-methylcytisine (C12H16N2O), and other alkaloids. Flavonoids: The flavonoids contained in Sophora flavescens are mostly dihydroflavones and dihydroflavonols, and there are also flavones, isoflavones, chalcones, etc. The flavonoids...
