Abstract: An emulsifiable composition, suitable for use as a lubricant for textile fibres, comprises a major proportion of mineral lubricating oil and minor proportions each of an oil-soluble naphthasulphonate, an oil-soluble non-ionic emulsifier and a nitrogenous emulsifier which is soluble in oil but substantially insoluble in water. The naphthosulphonate is a salt obtained by neutralizing petroleum mahogany sulphonic acids with an alkali metal hydroxide, ammonia or an aliphatic amine or alkylolamine. The oil-soluble non-ionic emulsifier may be a monohydric or dihydric alcohol or an alcohol carrying substituents such as ether and/or ester groups, examples of these classes of non-ionic emulsifiers are given. If desired, a mixture of two or more oil-soluble non-ionic emulsifiers may be employed, and a mixture of glyceryl dioleate and diethylene glycol monolaurate, with or without monoethylene glycol mono-oleate; is specified. Suitable nitrogenous emulsifiers are primary, secondary and tertiary amines containing at least one hydrophobic group attached to the nitrogen atom substituted isoureas isothioureas guauidines, iminazoles, imidazolines and pyrimidines and salts of such substituted compounds with inorganic or organic acids such as hydrochloric, acetic, stearic or oleic acid. Examples of the various classes of nitrogenous emulsifiers are given; mixtures of nitrogenous emulsifiers may also be employed. The emulsifiable compositions may also contain coupling agents or mutual solvents (e.g. lower monohydric alcohols, phenols, glycols, polyglycols and glycol mono-ethers), anionic emulsifiers (e.g. alkali metal salts of higher fatty acids, rosin acids, sulphated alcohols and alkyl aryl sulphonic acids), antioxidants (e.g. 2, 4-dimethyl-6-tert. butyl phenol, N-butyl p-phenylene diamine and tetramethyl diaminodiphenyl methane), antifoaming agents (e.g. silicones, N, N1-distearyl ethylene diamine and N, N1-distearyl hexamethylene diamine), fungicides (e.g. salicylanilide) and corrosion inhibitors (e.g. primary amines, alkyl-substituted oxazolines and oxazoline salts of fatty acids). If desired, the emulsifiable compositions may be applied to textile fibres in the form of aqueous emulsions. In the examples, mineral lubricating oil compositions are described containing sodium naphthasulphonates, glycerol dioleate, diethylene glycol monolaurate (with or without "Cithrol A"), 1-b -hydroxyethyl-2-heptadecylene imidazoline, colophony rosin, oleic acid, potassium hydroxide, isopropyl alcohol and water.
