A liquid low-foaming nonionic surfactant composition is provided which exhibits superior wetting characteristics and general good scouring and/or detergency properties which comprises a block-random structure represented by the formula

Low-foaming nonionic surfactants

Lubricant compositions for finishing synthetic fibers which exhibit improved thermal stability and low-fuming characteristics are provided which contain 50 to 90 percent by weight of a thermally stable lubricant and 10 to 50 percent by weight of an emulsifiably effective surfactant having the formula:

Lubricant compositions for finishing synthetic fibers

An improved method is provided for treating and processing textile materials which comprises contacting said textile materials with an aqueous composition containing a low-foaming, nonionic surfactive agent having a block-random structure represented by the formula:

Method for treating and processing textile materials

Esters of lower aliphatic dibasic acids and fatty alcohol alkoxylates have been prepared having excellent low-foaming and scouring properties.

Low foam scouring agents

A spin finish for synthetic fibers has been developed consisting essentially of a thermally stable lubricant and a surfactant derived from an ethylene oxide/propylene oxide block co-polymer adduct of an alkylated phenol.

A process for the reductive alkylation of secondary amines with either aliphatic aldehydes or aliphatic ketones in contact with hydrogen, a water-segregating agent and a hydrogenation catalyst to form tertiary amines.
