Istarted with Emulsun from Floratech becuase I like the feel and they claim it’s sprayable at 2% level and Veegum HV (mag alum sil) supposedly helps with the spaying. My oil phase is 9% an ester and cap/cap .I have done different iterations. In the past, straight emulsifying wax at 3% is sprayable, but I wanted something ifferentThanks for the great information. I will not be using silicones, so CETAC or Pemulen are great options. I am going to try Croda’s Arlacel LC (which is nice) along with their Volarest FL ( Acrylates/Beheneth-25 Methacrylate Copolymer). I will update after i work with it. Thanks for all the comments.

I would just like to add, having viscosity build issues myself with a sulfate-free formula (different surfactant blend altogether), guar gum was giving me problems. Is it actually guar gum or Guar Hydroxypropyltrimonium Chloride? If it’s the latter it will fight with the xanthan gum (there are many types of xanthan gum) the Guar Hydrox… is cationic and the xanthan gum is ionic. I would remove the xanthan gum and replace with Hydroxypropyl Methylcellulose, Ashland has Bencel K200M and Univar has Methocel 40-1010 PCG. If your guar gum is actually guar gum you can try leaving it in, but you may have to remove. I personally like guar gum because of its silky feel.

Hi Mark,
That’s a good thought; I will try. have you ever tried Sola Tara (Caesalpinia Spinosa Gum) other companies have that one as well. I appreciate your input. and will try and get back to you. thanks. J

oh, for clarification the KOH is an 18% SOLN.

Hi, Thank you for your comments and suggestions. The pH was low, I believe because of the Aloe Vera Juice, although, I can’t be certain. The pH needs to be above 7 for the client. I will replace the GSC with something else, perhaps Ceteareth-20 and play around with some of the other surfactant suggestions. The client wants as natural and mild as possible. Thanks so much!

Hi Guys,
Thanks very much for your thoughts and suggestions. I wanted to stay clear of DPG /surfactant bucause it’s a banned solvent in this company; interesting though. I finally got Polysorbate 20 to hold those amounts and it looks good. Not my first choice, but it works. Thanks. -
That’s great, thanks. I increased the oil content and it significantly reduced. I like your suggestions.

That is interesting. Would emulsifiers with a higher HLB requirement be less likely invert to w/o and thus to soap? I am running into this issue with a chassis that I have used several times: olivem 1000 (hlb 9) with cetearyl alcohol. The only difference now is that I am not using dimethicone, which I think suppresses soaping. Do you think Cetyl Alcohol will help because it’s hlb is significantly higher?

Hi, I just read Perry’s post on this and it seems clear to me that salt works as a thickener with anionic and anionic/nonionic combinations due to charge density. Any comments are welcome. thank you
