I was using only EOs, but recently made my very first FO purchases. I found the long strings of product reviews on the websites to be useful. Various individuals focus on different notes and if the reviews are numerous, you can work out the fragrance based on the different opinions. Since I’m a soaping and FO newbie, I researched the favorite scents of different members here (and what they said about the characteristics of the scent), decided to stick with two companies (MMS and BB), read the FO spreadsheet entry if there was one, read the FO descriptions on the sites, and finished up with the customer reviews (BB only because I couldn’t find customer reviews at MMS). I took notes and even made my own spreadsheet so that I could select FOs that result in little to no acceleration or discoloration and record the high, moderate and low scent usage rates. Whew, it was a LOT of work. It was worth it because, out of over a dozen FOs, there is only one that I might not have purchased if I smelled it in advance. I understand that some scents change with time in the soap, so I’m keeping an open mind about that one. I don’t sell soap, which means there in no need to try to figure out what customers would like. I’m sure that can be challenging. I even bought one FO that some reviewers hated. I wanted something an FO that smells like the beach, wet seaweed and all. Thanks to the reviewers, I got my scent!
