Span 40, also known as sorbitan monostearate, is a non-ionic surfactant commonly used in various industrial and pharmaceutical applications. It is derived from sorbitol and stearic acid, and its chemical structure consists of a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, which allows it to reduce surface tension and stabilize emulsions. Span 40 is characterized by its ability to act as an emulsifier, helping to blend oil and water phases in formulations. It is typically a yellowish to brownish waxy solid at room temperature and is soluble in oils but only slightly soluble in water. This surfactant is widely utilized in food products, cosmetics, and pharmaceuticals for its emulsifying properties, enhancing texture and stability. Additionally, Span 40 is known for its low toxicity and is generally regarded as safe for use in various applications, although specific regulatory guidelines should be followed. Its effectiveness can be influenced by factors such as concentration, temperature, and the presence of other ingredients in a formulation.
