CETAC 30% Causing Irritation!

SasseSasse Member
I noticed that whenever I include CETAC 30% in my conditioner formulation it seems to sting a bit as I rinse my hair. It’s feels like little pinches on my face here and there. I get no blotches or anything on my face or body after, but it’s just really irritating and I would rather not have that. 

My question is:

Is CETAC 30% too much at 1.5% in a deep conditioner formulation? 

These are the other ingredients in the formulation:

Honeyquat
C13-15 alkane
Caprylic/Capric Triglyceride 
Panthenol 
Glycerin 
Aloe Vera Juice 
Btms
Stearyl alcohol 

Could any of these ingredients be causing the the reaction with the CETAC 30%?

Many thanks,

Sasse

    I am also using Optiphen plus as a preservative at 1% 
  • I don't think it's too much, it's probably too little.

    What is the product's pH?

    Hello alchemist01, thanks for replying!

    The most recent one I formulated was a 3.45. I thought it was a bit low. 
  • I think that pH is a little low for a conditioner. I have no idea if that's the issue, but it should be a quick adjustment to try. I would try and bring it closer to 4-5, but that's a personal range. For a rinse-off conditioner cetrimonium chloride is usually more like 2-3% active. If you feel your product works well you can leave it as is (maybe whatever your honeyquat % is makes up for it), or change it once you resolve the stinging.

    Maybe someone with more experience than I can pick out incompatibilities with your LOI, but if none of that helps you should just try cutting out ingredients one by one to pinpoint the issue.
  • What's your BTMS level? It can also be irritating. You could also try upping your stearyl alcohol percentage, as fatty acids are known to reduce the irritation potential of cationic surfactants.

    Thank you all for the comments, and sorry for the late reply. 

    @alchemist01 I might just have to let go of the CETAC and up my Honeyquat levels as suggested. I’m not familiar with how to increase pH, only how to lower. 

    @LincsChemist I am using 5% Btms and 3% stearyl alcohol.
