- the dialkyldisulfimides have a strong acid reaction in the free state and may suitably be used in the form of their alkali metal salts such as the sodium or potassium salts, or ammonium salts or mixtures thereof, the ammonium salts also including the salts of organic bases, preferably organic amines such as mono-, di-, or tri-lower alkylamines or lower alkanolamines such as mono-, dior tri-ethanolamine.
- the dialkyldisulfimides may also be utilized in their free state particularly where an inorganic builder is utilized as the component (b).
- the alkyl residues contained in the dialkyldisulfimides may be the same or different or may be branched.
- dialkyldisulfimides with straight-chain alkyl residues are preferably used, among which di-n-octyl-disulfimide has been found particularly active.
- the dialkyldisulfimides are selected from the group consisting of l) dialkyldisulfimide having 6 to 10 carbon atoms in the preferably straight-chain alkyls and (2) their alkali metal salts, ammonium salts and salts with lower alkylamines and lower alkanolamines.
- the washing, rinsing and soaking agents according to the invention contain at least one inorganic or organic builder salt from the class of polymeric alkali metal phosphates, alkali metal silicates and the alkali metal salts of aminopolycarboxylic acids and polyphosphonic acids.
- Suitable polymeric phosphates are pyrophosphates, triphosphates, tetraphosphates, trimetaphosphates, tetrametaphosphates, and more highly condensed phosphates, in the form of the neutral or acid sodium, potassium or ammonium salts.

Their relatively great stability towards oxidizing agents possibly is due to their low content of free sulfliydryl groups.
- the enzymes represent a valuable addition to the agents of the invention, since they are already active at temperatures at which the dialkyldisulfimides have not yet developed their full activity.
- the disulfimides are completely stable towards strongly alkaline or active chlorine-containing compounds even at temperatures above 70 C. while most of the known enzymes are already inactivated to a considerable extent under the said conditions.
