Sepimax Zen - tips/tricks
I will be using Sepimax Zen for the first time. Working on a relatively simple acid exfoliant.
I can’t seem to find formulation guidelines for this material. I have reached out to Seppic.
My question is - do you add the polymer to the aqueous base before the addition of the acids/solvents, or do you add everything together and then add the polymer at the end?
I appreciate any insight from those who have worked with this material! Thank you.

Matt (another Matt here? uh oh!) - always disperse and hydrate the polymer into water at RT first before adding any other component.

I’m sure you know….but Zen below .5% is a wonderful thing, and above that…kinda becomes giggly and gross.

@chemicalmatt haha Hi, Matt!
Thank you for the input! Saves me some wasted time. @Graillotion I do not know that since it is my first time working with the material! But good to know. No one wants giggly and gross!
I’ll be sure to start at 0.5% and see how things turn out. Thank you! -
Well…when working with a polymeric like that….just take water…and mix it at several ratios….
say .35, .5, and .65%….and see the resulting product….and determine which one you like the best. I think much over .75…you’re looking at a solid…hehehe.
Skip all the other ingredients….just find the viscosity and feel you want of the Zen.

Off topic - maybe I should change my name to Mattsi, increasing the Matt population is global agenda.

Call me Pharmatt o:) -
It will turn out as a giggly marmalade look at about 1% when using normal ingredients.
Though you should just try it at 0.5% and 1% to see how much a loss of viscosity it would be due to the acid.

@Pattsi and @Pharma you both are welcome to the Matt Club, glad to have you both. Regarding that giggly effect with acrylate polymers: it may be mitigated somewhat by adding surfactants to the formulation but also limiting use of alkyl esters, fatty alcohols and other factors that associate highly with these materials.
