Abstract
A composition which is effective in removing a wide variety of contaminants, such as organic compounds, from a wide variety of environments, such as printing systems, is provided. A process of preparing such composition includes contacting hydrogen peroxide, glycolic acid, and water. The process can additionally include contacting with one or more additional components such as isopropyl alcohol.
Claims8
A process for producing a composition consisting of:
- (a) selecting a hydrogen peroxide solution, wherein the hydrogen peroxide solution consists only of (1) hydrogen peroxide, water, and low solids water having less than 10 ppm dissolved solids;
- or (2) hydrogen peroxide, water, low solids water having less than 10 ppm dissolved solids, and isopropyl alcohol;
- (b) preparing a glycolic acid solution by mixing a first solution with a low solids water, wherein
- (i) the first solution is, glycolic acid, water, and optionally, isopropyl alcohol,
- (ii) the low solids water has less than 10 ppm dissolved solids,
- (iii) the weight percent of the glycolic acid in the glycolic acid solution is between 1% and 15% by weight, and
- (iv) the glycolic acid solution consists only of (1) the glycolic acid, water, and the low solids water or (2) glycolic acid, water, the low solids water, and isopropyl alcohol;
- and
- (c) mixing only the hydrogen peroxide solution and the glycolic acid solution to form the composition.
