Abstract: Hydroxy mixed ethers are claimed which are obtd. by ring-opening reaction of unsatd. fatty acid ester epoxides (I) with polyglycol ethers of formula R1-O-(CH2.CHR2.O)n-H (II) in presence of Lewis acids with exclusion of protons (where, R1 = H, 1-30C alkyl or 8-30C alkenyl; R2 = H, Me or Et; and n = 1-50 (R1 not = H) or 2-50 (R1 = H)).
