ABSTRACT OF THE DISCLOSURE: Nonionic surfactant compositions are made by reacting a 3 to 30-unit polyglycerol as hydrophile with a hydrophobic glycidyl ether in sufficient quantity to substitute 4 to 25% of the hydroxy groups of the polyglycerol. By using glycidyl ethers (which can be made conveniently by reaction of hydro- phobic alcohol with epichlorohydrin) it becomes possible to avoid the expense of working with long-chain 1,2-epoxides. The surfactant compositions obtained have solubility and stability in a variety of concentrated ionic solutions, and especially in basic media.
