  • What’s the difference between Trideceth-12 & Behentrimonium Methosulfate?

    I’m trying to create a Hair Botox formula at home and I plan on using BTMS in it. I was wondering what’s the difference with BTMS & Trideceth-12? I tried googling it and I’m getting different definitions. Some of the information says it’s a cationic surfactant, some say it’s an emulsifier/conditioner. I’m really confused! If I want to incorporate it in my formula, would it compete with the BTMS? I understand I don’t need multiple cationic surfactant. Using only one is better.

    The reason why I’d like to add it if it doesn’t compete with BTMS is because my hair seems to like it. I bought a deep conditioner from Arvazallia awhile back and It’s listed as one of the ingredients. As I believe Trideceth-12 is combined with Cetrimonium chloride and Amodimethicone. I already have Amodimethicone in my formula, and I thought of swapping the Cetrimonium Chloride with BTMS, but I’m interested to know if Trideceth-12 compete with BTMS or not

    This almost sounds like a trick question, but here goes. The Answer: everything. Trideceth-12 is a nonionic surfactant used in the ubiquitous amodimethicone/CETAC hair conditioning-styling blend you ID’d simply as an emulsion aid/wetting agent helping it to incorporate into your formula on its own. It serves no other purpose and does not compete with BTMS at all; if anything helps it emulsify oil additions. You may add BTMS in collaboration with the Amo/CETCA/TD-12 blend Your hair will be softer in the end.

    Thanks for the tip. Wouldn’t adding CETAC with BTMS would make them compete since the do the same thing?

    I found that removing CETAC from my formula which contained BTMS had absolutely no change in end results. Once I scaled my production to mixing tanks, CETAC + BTMS would tend to make the final product clumpy. I did not want to purchase a different mixing tank with better mixing so I experimented with removing the CETAC an it worked great. I also use Amodimethicone but as a stand alone ingredient.

    Perhaps the mixture you are using with Trideceth12 will not create the clumping effect (I never tried it) however

    1. CETAC added absolutely nothing in my formula already containing BTMS.

    2. Amodimethicone was a gamechanger for a very finicky salon client (Added to BTMS/Dimethicone)
