How to neutrallize hair stylers

At least in Brazil most suppliers tell they offer hair stylers ingredients already neutralized. But I've come to find out they are never 100% neutralization. So, I've been trying to hair stylers for the moment and would like to know how do you guys neutralize Polyquaternium-11 and Belsil P1101. If you have experience with any other hair stylers ingredient and it must be neutralized, please share!

    Gustavo, my only experience with anionic styling resins is with the terpolymer Amphomer series from National Starch  (now Akzo-Nobel?) and the ISP Gantrez series.of PMMA/VA copolymers (now Ashland?)  These folks give you the equivalent weight and you plug in the correct MW for your alkaline agent, which I recommend be AMP or AMPD, also the degree of neutralization, and this gives you the various properties of film pliability - which you are obviously schooled in already.  A helpful hint: use an alkyl amine (e.g. cocamidopropyl dimethylamine) to neutralize and you'll get a nice firm hold with added humidity resistance, yet a nicer feel. Brazil, eh?  Wish I was there - it's minus 10C here in Chicago. Best of luck to you.
  • Thanks @chemicalmatt! I wouldn't dare to say I'm schooled in film pliability. Before this project I only worked with PVP for a traditional (and old fashioned) hair styling gel. Most of my work it's been on natural look. And I've been trying to test those polymers in low concentrations in order to get slightly fix without looking like styled. Brazilian women are terrible in that point. It's been a great challenge though.
    In your respect I won't mention local temperature in Rio. But yes, it's way warmer than Chicago.

  • Hello, Gustavo! Unlike you, I work mostly on skin care formulations, but recently I have created a hair styling line based on Lubrizol's hair fixatives. The results I have got are amazing. I have used alkaline capabilities of Arginine for neutralizing. Beside the good esthetic performances, those gels yield additional conditioning effect on hair, including improved moisturizing and incredible shine. The volunteers that have tried the samples during the month, have noticed less hair loss and improving in hair grow as well. Although this effect require additional and long term studying.
  • That's such a great idea @vitalys! I never tried arginine for that purpose also. Thanks for sharing!

    Can I neutralize amphomer with NaOH ? Because I am using another polymer in the formula to thicken that works pretty good with NaOH.
