Abstract
A prewetted cleaning wipe for cleaning surfaces and having low volatile organic chemical and low nonvolatile residue properties comprising a wipe substrate wetted with an aqueous solution of high purity water and an effective amount of an acetylenic alcohol surface active agent. The surface active agent is preferably an acetylenic diol. Preferred acetylenic diols include dimethyl octynediol and tetramethyl decynediol.
Claims18
A prewetted cleaning wipe for cleaning surfaces in an electronic materials fabricating area having a low volatile organic chemical content in the range of 0.001% to 0.5% by weight and low nonvolatile residue property of at least 1×10−4 torr at 25° C. comprising;
- a woven fibrous polyester/cellulose wipe substrate wetted with an aqueous solution consisting essentially of high purity water selected from the group consisting of distilled water and deionized water, and from 0.001% to 0.5% by weight of an acetylenic diol surface active agent selected from the group consisting of dimethyl octynediol, tetramethyl decynediol and mixtures thereof.
In a cleaning wipe for use in cleaning an electronics fabrication industry clean room comprising a wipe substrate wetted with a cleaning solution, the improvement which resides in a cleaning wipe having low volatile organic chemical and low nonvolatile residue properties comprising a wipe substrate wetted with a solution consisting essentially of water and from 0.001% to 0.5% by weight of an acetylenic diol.
