Details... Some seem to be missing. OK Scientist the 20 drops is OK with water, but most of the solutions talked about are not water, everyone be aware. The rule works with water, but? The best way to get a mL vol is to take a small test tube (or whatever is handy) and weigh a gram of water in it and mark the level. If you are wondering about the device to weigh things, in general cooking supplies are a good place to start. Tough if you?re American, but you have to deal with the problem that there will never be a ?Fourth and centimeters? quote on Monday night?
Next, Glycerol (aka Glycerin, it is the same stuff no matter where the source) if anybody has ever had an ice creme (misnomer) from Dairy Queen, it is about 30-35% glycerol. The body actually likes the stuff, it is used for the backbone of fat. It is an alcohol (actually there are three alcohols on the molecule, but I am nrrding out) much like antifreeze, but not toxic. The body uses it for all kinds of things. Other alcohols should be readily soluble in it. I have to wonder though, the Pher?s tend to be rather hydrophobic, and would seem to be more suited to oils, but I do admit, what ever works? (Nice run on, eh?)
The next thing bugs me for various reasons, as a chemist (no really, I am a NMR and Fluorimeter guy) Fragrances are a bit of a mystery to me. Aftershaves are approx 20 times less powerful than colognes. So the mixing ratios are subject to large errors. One thing that would be very helpful, would be if everyone was boringly detailed. Hey it is for the good of the bunch, right?
