Novel compounds having the structure (I) are provided, where R1 represents hydrogen, an alkyl group containing 1 to 3 C atoms, or a group R3; R2 represents an alkyl group containing 2 to 22 C atoms, wherein said group can be linear, branched, or cyclic and saturated or olefinically mono- or polyunsaturated; R3 represents a saturated alkyl group containing 1 to 3 C atoms, wherein said alkyl group is substituted by a group —O—(CH2—CHZ—O)p—H at one of the C atoms; X, Y, and Z independently represent hydrogen or a methyl group; and n and m independently represent a number ranging from 1 to 45, and p represents a number ranging from 0 to 45, provided that the sum of n+m+p has to range from 2 to 70. The compounds having structure (I) are excellent low-foaming surfactants. |
