Guest guest Posted November 13, 2007 Report Share Posted November 13, 2007 Good Morning Everyone! I have a question regarding the use of menthol crystals....another one of those, " this is so simple that I can't seem to find the answer " . I would like to develop a skin care product for after shaving, that has a nice cooling effect. Of course immediately what comes to my mind are " menthol crystals " which I have on hand. But I know very little, which really means....I know next to nothing about the proper way to work with them. What is a safe level to use? How do you use them....just add them straight? how do you measure them ? they are so very light that it takes alot to even measure one gram. Should I do a 10% dilution ? and then what percent of a 10% dilution is correct....about 2% added to the total 100% weight of the formula ?? After a few experiments working with them straight, my instinct is telling me that I need to dilute them to have a more accurate way to work with them, but I'd be grateful for tidbits of " how to " XXWarm Regards, Colleen I have looked thru the archives for this answer but don't see anything. If anyone has any experience in working with Menthol crystals on proper usage and safety, ratios.....anything. I'd be grateful. TIA Kind Regards, Colleen Quote Link to comment Share on other sites More sharing options...
