What is POLYGLYCERYL-3 POLYRICINOLEATE used for?
Polyglyceryl-3 polyricinoleate helps water and oil to mix and thus works as an emulsifier in cosmetic products. It works particularly well for buttery lip balms and other soft to low-viscosity water-in-oil emulsions that have a pleasant, non-greasy skin feel. It also works as a stabilizer, thickener, and anticaking agent. It helps to adjust the product’s surface tension and viscosity. It is used in the concentrations of 0.1-3.0%.
Origin
Glycerol is heated to above 200°C in a reactor in the presence of an alkaline catalyst to create polyglycerol. Castor oil fatty acids are separately heated to above 200°C, to create interesterified ricinoleic fatty acids. The polyglycerol and the interesterified ricinoleic fatty acids are then mixed to create Polyglyceryl-3 polyricinoleate. Instead of fatty acids from castor oil, those from soybean oil may also be used to produce PGPR.
