Acid Thickener
Hello Friends,I am trying to formulate acid thickener to thicken aqueous HCL solution wherein HCL concentration would be 15%. Purpose is to preapare an acidic toilet bowl cleaner. I am using the below formula to come up with a base thickener solution. Propylene glycol is used to disperse tallow amine ethoxylate when added to water or acidic solutionTallow amine ethoxylate 50%Propylene glycol 50%When i add the above base thickener to aqeous HCL solution, it doesnt thicken it. I tried using Oleyl amine ethoxylate as well. Any suggestions on the formulae from your end please? -

Have you tried HEC?

@amitvedakar: I am not inclined towards HEC or polymers to thicken acid solution. Looking for amine ethoxylate to use as i use the same material for other formulations and it will help me reduce inventory maintenance.

Any suggestions from seniors in forum please.
I tried using cetrimonium chloride and oleyl amine ethoxylate. But still no luck. -
@getmeraju not a senior, but I get a sense that the issue is the propylene glycol. I observed a thinning effect in a liquid detergent, and I remember reading somewhere that it usually reduces viscosity. Not sure in your system if this will be true. Have you used this same method to thicken other acidic solutions?

@letsalcido is right avoid Propylene glycol. You get better result with Oleyl Amine Ethoxylate , Cetrimmonium Chloride, HCL (should be Fe free ie. Water white) & DM Water.

Thanks Lalith. Will try and keep you posted
@letsalcido Thanks for your suggestion as well -
You should remove PG in this formulation and you can use salt for dispersion

try sodium lauryl sulphate
