Ok, In my experiences, When you're making something from scratch, I would definitely test it yourself for 2 weeks to make sure the product won't go rancid, mold or watery after while, if you're pleased with good result, then ask for your family and friends to test it out for ya. now with using like BB ready made batches, testing is still needed but not as long. for sample, as I had to find out the hard way. I made MP soap and packed it up and all that after my testing. only Later to find out that it turned brown on me, or it got this beady thing all over it, *which turned out to be sweat* so it was cause of vanilla base that was in f/o and all. Then it was back to drawing board to find out why and what not. I would really make sure you test your bb products, check to make sure there's not a lot of oil in products while bathing, don't want a lot of slippage going on in the tub/shower. make sure no one breaks out in rashes lol and that they aren't turning blue from colorants...hahaha I'm no expert and I'm sure others will chime in. but everything you make should be tested and tried by others to get opinions and results.
