Novel oil-in-water emulsions, which contain n (a) 0.1 to 80% by weight of at least one sparingly water-soluble active compound (as herein defined) selected from agrochemical active compounds, active compounds for combating pests in the domestic field and hygiene field and/or pharmacologically active compounds, n (b) 1 to 20% by weight of at least one alkylaryl polyglycol ether of the general formula ##STR1## wherein R 1 represents a hydrogen atom or an alkyl group having 1 to 16 carbon atoms, n R 3 represents a hydrogen atom or a methyl group, n m is 1, 2 or 3, and n n is an integer from 10 to 50, n if appropriate in a mixture with an alkylarylsulphonic acid salt of the general formula ##STR2## wherein R 3 represents an alkyl group having 8 to 35 carbon atoms and n Me.sup.⊕ represents an alkali metal cation, an equivalent of an alkaline earth metal cation or a cation of the general formula ##STR3## wherein R', R", R'" and R IV independently of one another represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a hydroxyalkyl group having 1 to 4 carbon atoms, n (c) water, n (d) if necessary, 1 to 30% by weight of at least one poorly water-miscible organic solvent and/or a solubilizer, and n (e) if appropriate 0.05 to 15% by weight of one or more additives, n the sum of the components being 100% by weight in each case, n a process for the preparation of these emulsions and their use in the field appropriate to the active compound. |
