Dissolving Betaine salicylate
I’m making a scalp exfoliator with
4% betaine salicylate
2.4% triethanolamin
2% allantoin
10% cocamidopropyl betaine
1% hydroxyethylcellulose
1% phenoxyethanol and ethylhexylglycerine
2% glycerine
3% pentylene glycol
Q/s water
The supplier advised I use a 1:0.6 ratio of BS and TEA
I achieved a clear gelly consistency but after sometime the betaine salicylate begins to recrystalize. My final ph was 3.9
What is going wrong?

Are you sure it is Betaine Salicylate and not Allantoin? 2% is very high, Allantoin has weak solubility in water, I usually add not more than 0.5% of water content (not the whole formula). Try making a test batch without it and see if it helps

Will try that and revert. Thank you!
