Abstract

Abstract This invention relates to liquid cleaning compositions and more particularly, to compositions that have a low pH, i.e., about 9.5 or below, and which consist essentially of, on a weight basis, about 3-10% surfactant, 1-3% isopropyl alcohol, 1-3% citric acid, 0.5 to 1.6% sodium tetraborate, 0.02 to 1.2% anhydrous sodium hydroxide, 0 to 1.0% anhydrous ammonium hydroxide and 84 to 95% water.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 89 words
A liquid detergent composition consisting essentially of, on a percent by weight basis as formulated, about 3 to 10% of a nonionic surfactant, 1 to 3% of isopropyl alcohol, 0.78 to 3% anhydrous citric acid, 0.5 to 1.6% sodium tetraborate, 0.2 to 1.2% anhydrous sodium hydroxide, and the balance being water to make 100%, the quantities of basic and acidic materials being selected so as to provide a composition having a pH of 9.5 or less, said composition being nontoxic by ingestion and not a skin or eye irritant.
Claim 2
Dependent Claim 89 words
A liquid detergent composition consisting essentially of, on a percent by weight basis as formulated, about 3 to 10% of a nonionic surfactant, 1 to 3% of isopropyl alcohol, 0.78 to 3% anhydrous citric acid, 0.5 to 1.6% sodium tetraborate, 0.2 to 1.2% anhydrous sodium hydroxide, and the balance being water to make 100%, the quantities of basic and acidic materials being selected so as to provide a composition having a pH of 9.5 or less, said composition being nontoxic by ingestion and not a skin or eye irritant.
Claim 3
