Abstract: A dishwashing composition which can be used in the conventional manner to obtain good foaming and detergency and can also be used in dilutions of about 5:1 or less to obtain a non-stick effect on aluminium pans contains from 10-50% of a detergent of which from 5-40% is a calcium/magnesium sensitive anionic synthetic detergent, from 0.01-2% of a selected alkyl phosphate monoester, and from 1 to 40% of a solubilizer.An example of such a composition has the following formulaton:% ______________________________________ Sodium dodecyl benzene 30.0 sulphonate Ammonium C.sub.12 -C.sub.15 primary 8.0 alcohol 3EO sulphate Lauryl phosphate (12%) 0.5 Succinic acid 1.5 Glutaric acid 1.0 Ethanol 6.0 Urea 6.

Abstract: A detergent composition suitable for hand dishwashing and in particular for aluminium pan cleaning which has a pH of from 4 to 8.5 and consists of the following essential components: from 10 to 50% by weight of a detergent, from 5-40% of which is a calcium/magnesium sensitive anionic synthetic detergent; at least 1% of a solubiliser and 0.015-0.45% of an organic phosphonate. When used at dilutions of about 5x, the compositions can provide anti-resoiling effects on aluminium.

Abstract: A machine dishwasher rinse aid having the property of imparting an anti-resoiling or non-stick finish to aluminium articles such as pans. The rinse aid contains an anti-resoiling agent which is preferably a monoalkylphosphate ester to achieve this effect. It also contains a nonionic surface active agent and a pH controller in the form of citric, lactic or glutaric acid.
