Micellar Size and Surface Activity of Some C18α-Monoglycerides in Benzene

Abstract

Some C18 α-monoglycerides in benzene have been studied by the light-scattering and surface tension methods. The glycerol esters of stearic, oleic and linoleic acids had micellar weights of less than 7,000; glycerol monoricinoleate had a micellar weight of over 18,000. All the mono-glycerides showed some surface activity in benzene, glycerol monoricinoleate having the greatest, the other unsaturated monoglycerides the least.
