US Patent No. 8,927,474 B2; SC Johnson & Son has been awarded a patent covering an aerosol product comprising a steel can with aerosol dispensing top, body and base.
The steel can has an interior surface with a lining, which is an organic coating or polymeric laminate, and optionally, a tin coating. The composition consists of water, compressed gas propellant, fragrance, pH adjuster, corrosion inhibitor comprising one or more of a phosphate, nitrite or silicate corrosion inhibiting compound, a surfactant which is either at least one nonionic surfactant or a blend of at least one nonionic surfactant and at least one cationic surfactant, and optionally a solvent selected from a group consisting of alcohols and glycols, a buffer component, and a preservative component. The composition is contained in said steel can and contacts said lining on the interior surface of the steel can.
The composition excludes anionic, amphoteric and zwitterionic surfactants. The corrosion inhibitor component, fragrance component and pH are selected so as to interact in a manner that maintains stable characters of corrosion inhibition, fragrance hedonics and formulation color.
