Hydrogen peroxide and persalt washing or disinfecting compositions perform comparatively ineffectively at ambient to low operating temperatures. More effective washing/disinfection processes are obtained by employing according to the instant invention there with a peroxyacid generator selected from compounds having the general formula (I): ##STR1## in which R.sub.1 and R.sub.2 and R.sub.3 often are hydrogen, R.sub.6 is often hydrogen or methyl and R.sub.4 and R.sub.5 are often methyl or phenyl. R.sub.3 or R.sub.5 can each also represent a difunctional group terminating at its other end in a second gem-diester group or in an enol ester group. Especially preferred peroxyacid generators include 1,1,5-triacetoxypent-4-ene, 1,1,5,5-tetraacetoxy pentane, the corresponding butene and butane compounds, ethylidene benzoate acetate and bis(ethylidene acetate) adipate.
A process for the generation of a peroxyacid species comprising the step of bringing into contact hydrogen peroxide or an adduct thereof or some other compound which develops hydrogen peroxide, with a peroxyacid generator having the general formula (I) ##STR9## in which R.sub.1 R.sub.2 and R.sup.6 are each selected from hydrogen and lower alkyl groups, and R.sub.3 is selected from hydrogen, lower alkyl and aryl groups and groups of formula (II) or (III) ##STR10## in which R.sub.7 represents a carbon-carbon bond or an alkylene diradical, R.sub.4 and R.sub.5 each represent hydrogen or a lower alkyl, or an aryl, aralkyl or alkaryl group and R.sub.5 can also be a from group of formula (IV) --R.sub.8 --CO--O--R.sub.9 in which R.sub.8 represents an alkylene diradical and R.sub.9 represents a vinyl or alkyl substituted vinyl group or group of formula (V) ##STR11##
