Abstract (en)

[origin: WO9857735A1] It has been found that block copolymer surfactants can be stabilized by the presence of small quantities of certain metal ions and/or a polyalkyleneglycol. The metal ions afford block copolymer surfactant stability at very low concentration of metal ion and safety advantages over conventional stabilizing techniques. The present invention is all the more surprising in view of the prior art which clearly indicates that metal ions would be expected to accelerate autoxidative degradation.
