@Heberth,
 1. Salicat MM : 0.5% is too high, out of regulation
2. HEC can not suspend beads
3. for saving cost, you can use Carbopol Ultrez-20, 1%

Thank you very much for your help, I will try Carbopol Ultrez as you mention and also reduce the Salicat MM.

Thank you, didn’t know about the allergic reactions my provider sell it to me as a safer or more natural option to DMD hydantoin

what you need is a surfactant-tolerant carbomer, e.g. Carbopol Ultrez 20/21; as you’ve discovered, HEC won’t help suspend particles

if you go down this route I strongly suggest taking out the quaternised guar as well, it’ll make things a lot simpler

Thank you very much, ill be taking your advise and remove guar.
