Abstract
A surfactant for use in an automatic dishwashing composition is provided, wherein the surfactant is a glycidyl ether-capped ethoxylated alcohol as noted in formula I. Wherein R1 is a linear, saturated C8-24 alkyl group, R2 is a linear or branched saturated C6-20 alkyl group, m has an average value of 10 to 50, and n has an average value of >1 to 2. Also provided are automatic dishwashing compositions comprising said surfactant.
