International Classification:

C11D 162

US Classification:

510241, 510495, 510504

Abstract:

A concentrate and a ready-to-use or diluted formulation for an aqueous vehicle cleaner can remove a wide range of different types of traffic film using either low pressure application, hand pressure application, water jet spray apparatus, clean-in-place systems or other manual or mechanical washing systems. The compositions may comprise, for example, one or more solutions that each or collectively contain or comprises: a) at least one anionic surfactant; b) at least one poly[oxyalkylene] ammonium cationic surfactant; and c) an alkaline agent. Optional additional ingredients may comprise at least one polycarboxylic acid chelating agent (preferably an aminocarboxylic acid chelating agent), at least one non-ionic or amphoteric surfactant, at least one hydrotrope, inorganic and/or organic acids and at least one silicate. The alkaline agent may provide a pH (when the finished product is diluted to 0. 5 to 5% by weight in water) will be between about 9 to 13.

International Classification:

C11D 162

US Classification:

510189, 510241, 510433

Abstract:

The present invention relates to compositions useful in the removal of road film and dirt from vehicles such as cars, trucks, motorcycles, snowmobiles, and the like. These compositions contain propoxylated quaternary ammonium cationic surfactants. Alternatively, the solution can contain quaternary surfactants containing both an ethoxylated group and a propoxylated group. These solutions contain at least one anionic surfactant such as a linear alkyl benzyl sulfonate, alpha olefin sulfonates, alkyl sulfates and secondary alkane sulfonates. The pH of the composition can be adjusted with either an alkaline or an acidulating agent such as metal hydroxides, sodium hydroxide, aminopolycarboxylic acids, and the like. The pH of the solution is between 2. 0 and 13, preferably between 8. 0 and 13.

Abstract:

A cleaning composition is provided according to the invention. The cleaning composition includes a product of mixing an acid component, a source of phosphoric acid component, and an oxidant component. The molar ratio of oxidant component to phosphoric acid component is preferably between about 2:1 and about 1:2, and the molar ratio of oxidant component to acid component is preferably between about 1:3 and about 1:5. A method of cleaning an aluminum surface is provided. The method includes a step of applying the cleaning composition to an aluminum surface, and rinsing the cleaning composition from the aluminum surface.

US Classification:

510255, 510189, 510197, 510245, 510254

Abstract:

An alkaline sensitive metal cleaning composition is provided. The alkaline sensitive metal cleaning composition contains an alkaline concentrate and a corrosion inhibitor concentrate. The alkaline concentrate includes a source of alkalinity in an amount sufficient to provide a use solution having a pH of at least 10. 0, and a first chelant component that exhibits soil removal properties when used at a pH of at least 10. The corrosion inhibitor concentrate includes a corrosion inhibitor component for reducing corrosion of alkaline sensitive metals when used in a use solution having a pH of at least 10. 0, a second chelant component for stabilizing the corrosion inhibitor in the corrosion inhibitor concentrate when the corrosion inhibitor concentrate is provided at a pH that is less than 8. 0, and a surfactant component for providing cleaning properties when used at a pH of at least 10. A threshold inhibitor/crystal modifier can be provided in at least one of the alkaline concentrate and the corrosion inhibitor concentrate to stabilize the corrosion inhibitor in a use solution at a pH of at least 10.
