A continuous process for the oxidative cleavage of vegetable oils containing triglycerides of unsaturated carboxylic acids, to obtain saturated carboxylic acids, comprising feeding to a first continuous reactor a vegetable oil, an oxidizing compound and catalyst capable of catalyzing the oxidation reaction of the olefinic double bond to obtain an intermediate compound containing vicinal diols: feeding to a second continuous reactor said intermediate compound, a compound containing oxygen and a catalyst capable of catalyzing the oxidation reaction of the vicinal diols to carboxylic groups, to obtain saturated monocarboxylic acids (i) and triglycerides containing saturated carboxylic acids with more than one acid function (ii); separating the saturated monocarboxylic acids (i) from the triglycerides (ii); hydrolyzing in a third reactor the triglycerides (ii) to obtain glycerol and saturated carboxylic acids with more than one acid function; and purifying said saturated carboxylic acids by fractioned crystallization by means of wash column (melt crystallization).

The invention relates to liquid washing agents having a pH value of <6.5, preferably in the range of 2 to 5, containing, based on the total weight of the liquid washing agent, (i) 5 to 30% by weight, preferably 10 to 30% by weight, in particular 15 to 25% by weight of at least one hydroxycarboxylic acid having 2 to 8 carbon atoms, (ii) 15 to 55% by weight, preferably 20 to 55% by weight, in particular 35 to 50% by weight of at least one non-ionic surfactant, (iii) 0 to 20% by weight of water, and (iv) at least one enzyme having a pH optimum of pH<7. Said liquid washing agents have an increased cleaning power, in particular on stains on the basis of components and residues from deodorants but also of grates, berries, tea and red wine residues.
