ABSTRACT:
A novel glycol and silicate-based surfactant composition is prepared by (a) obtaining a silicate-based component by a selective process involving (i) reaction of silicon tetrahalide with water and alcohol followed by (ii) transesterification with a polyether alcohol, and (b) subsequently combining the silicate-based component with glycols and/or polyglycol ethers. The resulting surfactant composition is utilized as a stabilizer in the production of polyurethane foam.
