Water-soluble cleaning replaces CFC cleaning has a problem of the gain of waste water. We have developed a glycol ether/water cleaning technique that recycles the cleaning agent, omits rinsing, and maintains of high detergency.The process, using a cleaning agent consisting of 35% glycol ether and 65% water, begins with a uniform solution at 30°C, which separates into two layers as the solution is heated to 60°C. The upper layer, consisting of 90% glycol ether, completely dissolves oil. The solution is then cooled. At 30°C the solution resumes its uniform state, leaving the oil separate. Once the oil is removed, the cleaning agent can be used again.The recycle of a glycol ether cleaning agent utilizes the dissolution and the separation with water by temperature. It is thought that the solubility of a glycol ether can be arranged with hydrophilic-lipophilic-balance (HLB) like a surfactant.
