Product Description
Emulsifiers are typically clear to pale-yellow liquids, powders, or waxy solids, depending on the type. They are amphiphilic molecules with a hydrophilic (water-loving) head and a hydrophobic (oil-loving) tail, enabling them to reduce surface tension between immiscible liquids like oil and water. Most emulsifiers are non-corrosive, pH-neutral (6–8), and soluble in water, oils, or organic solvents based on their chemical structure. They exhibit low volatility and high thermal stability, making them suitable for diverse industrial processes.
