Polyglycol esters which can be obtained by partially esterifying an oxalkylate of 1,1,1-trimethylolethane or pentaerythritol with a mixture of ethylene oxide and propylene oxide in the molar ratio of from 2:1 to 4:1 with sub-stoichiometrical amounts of a carboxylic acid having from 10 to 20 carbon atoms or an acylating derivative of such a carboxylic acid may be used as surface-active agents. The polyglycol esters increase and/or stabilize the viscosity of aqueous systems and are also suitable as emulsifying agents.

Polyglycol esters, process for their preparation and their use as

Disinfectants which are characterized in that they contain a mixture of a compound of the formula I ##STR1## in which R.sup.1 represents a hydrogen atom or a methyl group,

Disinfectant

Process for improving the sliding properties of linear polyester material in spinning operations, which comprises treating this material after the drawing with a mixture of the following components:

Fabric softening compositions in the form of liquid, aqueous dispersions, containing a condensation product of 1 to 1.5 mols of fatty acid or of a fatty acid ester of the formula I

Fabric softeners

A process for the conditioning of synthetic fibers, which comprises applying onto these fibers mixtures of alkane-phosphonic acid salts and alkane-phosphonic acid-semi-ester salts in a molar ratio of from 19:1 to 5:1.

Heat-resistant fiber conditioning agents

A process for the manufacture of synthetic staple fibers having a marked separating capability by preparing the synthetic fibers with fatty acid-amine-condensation products, which comprises preparing or conditioning the fibers, prior to the textile spinning processes, with fatty acid-hydroxy-alkyl-ethylene-diamine condensation products, the hydroxyalkyl radical or which shows 2 or 3 carbon atoms, and 1 to 2 identical or different radicals of saturated fatty acids having from 14 to 18 carbon atoms are present per mole of hydroxy-alkyl-ethylene-diamine.

Fiber preparation agents to produce a marked separating capability

A fabric softener which contains as fabric-softening agent from 1 to 35% by weight of a condensation product obtained from about 1 to 1.5 moles of a fatty acid or a fatty acid ester of the formula I

Peralkylated reaction products of .alpha.-olefin oxides of 8 to 18 carbon atoms with lower alkylene-diamines, dialkylene-triamines or trialkylene-tetramines are fiber lubricants which are capable of rendering the fibers antistatic.

Preparation for the antistatic finishing of fibers

Peralkylated propylenediamines having one long-chain alkyl or alkenyl group are antistatic agents for fibers.
