Title: Hard surface cleaners
Inventor: CROPPER JAMES D
IPC: C11D17/00
Filed: 1992-12-08
Granted: 2003-02-04
Abstract: The present invention relates to foaming hard surface cleaners, and containers comprising the same in an enclosure. It is known, to provide foaming hard surface cleaners in a metal can together with a propellant to dispense the cleaner. Corrosion may occur on the interior surface of the can, in regions where the can contacts the liquid phase and more especially in regions where the can contacts the vapour phase (ie. in the headspace) and it is known to include in the composition a volatile amine, preferably a primary or secondary amine or ammonia. It is desirable to prevent corrosion in the gas phase while maintaining an acceptable product fragrance. In the compositions disclosed herein, adequate head space corrosion protection is attained with lower ammonia levels, by inverting the can after filling and holding the can in an inverted position for a sufficient length of time for a protective film to form in the eventual upper region of the can and subsequently reverting the can to a conventional attitude to complete formation of a protective film in the lower region of the can.
