An ionic surfactant is a surfactant that carries an ionic group in the form of either a negative [11–13] or a positive head [14,15]; From: Developments in Surface Contamination and Cleaning, 2015.
What makes a surfactant?
Surfactants, or surface-active agents, are amphiphilic molecules. Their heads are polar, or hydrophilic, and their tails hydrophobic. They are soluble in both organic solvent and water. The surfactant reduces the surface tension of water by adsorbing at the liquid–gas interface.
What secretes surfactant?
Surfactant is synthesized and secreted by Type II alveolar epithelial cells, also called pneumocytes, which differentiate between 24 and 34 weeks of gestation in the human. It is made up of 70% to 80% phospholipids, approximately 10% protein and 10% neutral lipids, mainly cholesterol .
Which is an example of a biobased surfactant?
Applications of biobased surfactants span most market sectors associated with surfactants: laundry detergents, foods, cosmetics, personal care products, pharmaceuticals, paints and coatings, and environmental remediation to name a few. A list of commercially available biobased surfactants is given in Table 1.1.
Which is the largest biodegradable anionic surfactant in the world?
The two potentially largest volume, sustainable anionic surfactants, methyl ester sulfonate (MES) and alcohol ether sulfate (AES) are produced from palm oils or coconut oil. MES is biodegradable and can substitute for LAS.
