I have also used Euxyl PE 9010 and it is an excellent preservative. I haven’t done it in a few years but Sculke & Mayr the makers of Euxyl used toallow you to send them formulations to get their recommendation on the best preservative. I’m not sure if they still do this but you could look for the sales rep for your area and they would tell you if they still provide this service.

BobZchemist,

Is using Behenyl Alcohol instead of Cetyl Alcohol a direct replacement or is it formulation dependent?

Thanks

Thanks for the feedback EM. I was going to try HEC at 1% but you said it increased the viscosity a lot. Perhaps I can try 0.50% or 0.25%.

Has anyone ever studied the effect of combining natural thickeners to emulsions that also contain Cetyl Alcohol? I am making some hard to thicken emulsions and I’ve tried a couple of natural thickeners but if they are very high in Molecular weight they thicken the emulsion too much. Has anyone tried HEC, CMC or other natural thickeners? My instinct tells me to try lower molecular weight natural thickeners but I don’t know if these will do the trick or not. Also, if using natural thickeners, should I lower the amount of Cetyl and Stearyl Alcohol?

Thanks for any help or insight that anyone can give me on this.
