Abstract: A toothbrush comprising a head, a neck and a handle, the head comprising a readily flexed resilient member having a plurality of bristles arranged on one side thereof, and a rigid member depending from the neck, the resilient member resting on the rigid member and being arranged with an inner array of bristles between outer arrays of bristles on opposite sides thereof, the outer arrays being caused to splay divergingly from the resilient member as a consequence of deformation of the resilient member when the bristles are urged onto a tooth or gum surface.

Abstract: A toothbrush is provided having a handle and a bristle bearing head. The head includes a central skeleton, resilient side members mounted on either side of the central skeleton, tuft mounting receptacles in both the skeleton and the side members, and bristle forming tufts received in both the tuft mounting receptacles of the skeleton and of the side members. The side member bristle tufts are movable both sideways and downwards in a toggling movement relative to the bristle tufts stationarily mounted on the skeleton.

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.
