INCI & Labeling

SasseSasse Member
Hello everyone,

I am a bit confused with how to go about labeling ingredients that come combined like BTMS.

For instance, if I have 5% BTMS (behentrimonium methosulfate (20 - 30%) and cetearyl alcohol (> 50%)) in a formula, and I have 4% shea butter, which will I list first? 

Another example is if I have 1.5% optiphen plus (phenoxyethanol (52.25%), caprylyl glycol (41.73%), sorbic acid (6%)) in a formula, and I have 1% jojoba oil, which will I list first?

I have looked through the FDA cosmetic labeling site numerous times, but have not been able to get a clear understanding so your help will be much appreciated! 

Many thanks,



  • Labeling should be done based on the final concentration of ingredients. So, before figuring out the label you have to figure out the concentration of each of the INCIs you’re listing.

    It’s very simple. Multiply the concentration of the given INCI in the stock mixture, by the final concentration of that mixture in the formula:

    Optiphen plus at 1.5% means you have:
    phenoxyethanol .5225 * 0.015 = 0.00784 or .78% final concentration.

    Wow, thank you so much for the information! I was not sure if doing that would be considered incorrect or not. Now I know!
