vberkesch Posted May 12, 2016 Share Posted May 12, 2016 When I calculate the amount of fo needed for my sugar scrub, do I calculate from the TOTAL amount the recipe will make-in other words ( oils and butters and waxes and preservative AND the SUGAR) ? So if my recipe makes 120 oz when finished - do I multiply .02 by 120 and get 2% f.o. For my scrub? thanks all - vanessa Quote Link to comment Share on other sites More sharing options...
Shari Posted May 12, 2016 Share Posted May 12, 2016 I generally calculate my 1-2% on the total recipe before the preservative. Quote Link to comment Share on other sites More sharing options...
TallTayl Posted May 13, 2016 Share Posted May 13, 2016 Check out your IFRA certificate for usage limits first. Those limits are based on "finished product". Meaning oils, sugar, emulsifiers, Etc. Quote Link to comment Share on other sites More sharing options...
