Abstract
The present invention provides a biodegradable cleaning composition that includes a surfactant component including an ethoxylated 2-propyl heptanol, a chelating component including a tri-sodium salt of methylglycinediacetic acid and an emulsifier component including an ethoxylated hexanol having the formula CHO(CHCHO)H. The ethoxylated 2-propyl heptanol has the formula CHCH(CH)CHO(CHO)H, wherein p is a number of from 3 to 6. The composition also includes water and an acid component to establish a pH of the composition at less than 2. The composition is substantially free of solvents thereby reducing emission of volatile organic compounds and reducing potential environmental pollution and health hazards. The composition is also effective in removing rust, lime soap, and metal salts of fatty acids from hard surfaces including metal, vinyl, and fiberglass.
