Every now and then articles come up that any product containing vegetable shortening is a poison, thus we don't have such products as Crisco, even margarine is not made from vegetable shortening and water for a long time. Not sure about petrolatum, will have to check for its availability. Dictionary says that petrolatum is how Americans call Vaseline, I think its not true, because I did check unscented Vaseline contents and they don't even have petrolatum. According to Wikipedia (http://en.wikipedia.org/wiki/Petroleum_jelly) it can have many other names. If I find it, do you happen to know approximate formula for its usage with paraffin?
