Hi all, I have an electric shaver that I'd like to keep lubricated. It comes with a base station that uses small disposable cartridges filled with ethanol mixe= d with some form of lubricant which is most likely polar (so that it can dissolve in ethanol). Once this cartridge is empty, I don't want to buy another and instead fill it up with my own liquid. I was contemplating usin= g isopropyl alcohol, but that alone wouldn't be enough as I'd need a polar lubricant to mix with it. Someone suggested glycerol, (they claimed it's used to lubricate machines i= n the food industry). Can anyone verify this? Do you guys know of any good, thin polar lubricants which are safe for skin contact (since it's a face shaver)? Or: I could make something entirely non polar and use a non polar type (maybe organic, hydrocarbon based) lubricant. Initially I made a fluid composed of a liquid that I extracted form WD-40 (which is mineral oil, or so they claim). It works okay, but I don't think it's very safe for skin contact on a daily basis. Light hydrocarbons such as hexane (small chain hydrocarbons) are too volatile and are no good as lubricants. Cooking oils tend to go rancid, and their hydrocarbon chains are too long and make them very viscou= s so they're no good in that regard either. Car oils are a no no, as they hav= e a good chance of being carcinogenic. Honestly, the mineral oil that I extracted from WD-40 seems to be doing a pretty good job, so maybe something similar will do. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
