Ceteareth-20 in a BTMS based system with glyoxylic acid
I am manufacturing professional chemical hair straighteners using glyoxilic acid in 10% to sub 10% levels with pH 1.6 to 2.5 using BTMS-25. I also use ceteareth 20. The formulas also include Cyclopentasiloxane as the only silicone. IPM and CCT are also present.
I ran a couple of test batches without Ceteareth-20 and the emulsion turned out noticeably more liquid and slightly grainy, less cohesive overall. When I include a small amount of Ceteareth 20, it becomes thicker and smoother.
I want to test how a more fluid version of the product will effect the application on hair as it spreads more easily.
The only downside is that with ceteareth-20, the product no longer flows properly through my piston-filling machine. Viscosity is too high or elasticity too strong, and it clogs or pulses unevenly.
So my questions are:
-
1. Is Ceteareth-20 actually stabilizing the emulsion, or is it just altering rheology and sensory feel?
-
2. Has anyone else experienced processing issues (pumping or filling difficulties) related to Ceteareth-20 ?
-
3. Any insights on how it behaves during heat-activated keratin type treatments would also be really helpful.

I worry about raising the BTMS-25 input since the cationic load might interfere with the acid’s penetration and performance.
