Sorbitan Monolaurate (SML) Product Description
Sorbitan Monolaurate, commonly referred to as SML, is a non-ionic surfactant derived from sorbitol and lauric acid. It is a yellowish to brownish viscous liquid or a waxy solid, depending on the temperature. SML is widely used in various industries due to its emulsifying, stabilizing, and surfactant properties. It is particularly valued in food, cosmetics, pharmaceuticals, and industrial applications for its ability to improve the texture and stability of formulations.
SML acts as an emulsifier, helping to blend oil and water phases in formulations, which is crucial in products like creams, lotions, and sauces. Its low toxicity and biodegradability make it an attractive choice for environmentally conscious formulations. Additionally, SML can enhance the solubility of active ingredients, making it a valuable component in drug delivery systems.
