Abstract: The invention relates to a method for detecting identifying substances in dark-coloured mineral oil products which contain, as identifying substance, a compound of the formula I in which D is phenyl optionally substituted by methyl or methoxy, R is hydrogen or methyl, R is hydrogen or C1- to C4-alkyl, and R is C3- or C4-alkyl, by extraction with aqueous acid, which process is characterised in that an alkylphenol is added to the mineral oil product before the extraction.

Abstract: Fluid formulations of oxidation dyes, which are obtained by oxidizing a compound of the general formula I I where R1 is unsubstituted or hydroxy-, C1-C8-alkoxy- or C1-C8-alkanoyloxy-substituted C2-C13-alkyl, R2 is hydrogen or unsubstituted or hydroxy- or C1-C8-alkoxy-substituted C1-C13-alkyl and X is hydroxyl, amino or in an organic solvent, are particularly suitable for dyeing mineral oil products, fats and waxes.

Abstract: Stabilised diphenylmethane dyestuffs of formula (I): R = 1-4C alkyl; are in the solid aggregate state or in the form of an aq. soln. contg. tartaric acid (IIA) and/or citric acid (IIB). USE/ADVANTAGE - Addn. of (II) prevents the hydrolysis of (I), e.g. auramine (IA) (R = Me), esp. the technical form, normally occurring in conc. solns.. (I) are useful for dyeing paper.
