Abstract
Abstract The invention provides novel polyglycol ethers of formula I, r--c.sub.2 h.sub.4 o).sub.x --C.sub.3 H.sub.6 O.sub.y --C.sub.2 H.sub.4 O) z --H-- I in which R is alkoxy of 8 to 24 carbon atoms, X has a value of 9 to 10 Y has a value of 12 to 17 And Z has a value of 8 to 12. The new compounds have a number of uses in the dyeing and printing industries, for example as scouring and washing agents.
