Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
117 words
A composition for cleaning a surface comprising: at least one surfactant; a pH sensitive dye which changes color upon exposure to air; an alkali means for adjusting the pH of the composition to an alkali pH to produce a color in the composition so that upon neutralization in the air the dye loses color; a propellant system for foaming the composition; aid composition being a visually colored foam composition with the disappearing pH sensitive dye effectively indicating the delivery of the foam and giving a visual check as to the area contacted when the visually colored foam is applied; and said composition is packaged sealed airtight in a container adapted for propellant foam delivery of the composition.
Claim 2
Dependent Claim
117 words

Claim 3
Dependent Claim
12 words
A composition of claim 1 wherein said surfactant is diluted with water.
Claim 4
Dependent Claim
30 words
A composition of claim 1 including an effective amount of a solvent for solubilizing residual water insoluble matter in the range of 0.1% to 20% by weight of the composition.
Claim 5
Dependent Claim
17 words
