Polyglycerol esters demonstrate superior antifogging properties for films

As a result of their multifunctional properties and harmless nature, polyglycerol esters are widely used in many applications in the food and cosmetic industries. They notably function as emulsifiers, dispersants, thickeners, solubilizers, spreading agents, or emollients. More recently, new industrial applications based on polyglycerol esters have been developed. This includes their utilization as antifogging and antistatic additives, lubricants, or plasticizers. Dr. Valérie Plasman, Dr. Thibaud Caulier and Dr. Noel Boulos of Solvay discuss the use of polyglycerol esters as antifogging additives in polyolefin and PVC films. This application has been very popular in Asia for many years, and is now of growing interest in Europe and the United States.
