PassionSunKiss Posted August 23, 2014 Share Posted August 23, 2014 Hey all, I'm trying to make some roll on perfumes, and I was wondering what % you think I should go by? For example, almost all of NG's FOs say 5% maximum use, but when I check the IFRA certificates, the skin safe max will range between 5%-66% and some IFRA certs actually say "No Restriction". I've tried making some roll ons at 5% at NG's suggestion and you can hardly smell the FO after like 30 minutes. I was wondering what you thought the average, safe % was and why certain vendors have a % much lower than the IFRA limit? TIA! Quote Link to comment Share on other sites More sharing options...
