Handsoap become trouble
Hi everyone,
I’m working on a handsoap formulation based on cocamidopropylbetaine, sulfonic acid and SLS. We want to substitute the 0,05% Kathon CG in this formulation by 1% of a mix of Glucono-delta-lactone:sodium benzoate (75:25).The pH of our original formulation is 6,5. To use gluconolactone:NaBenz mix, I lowered the pH of our formulation to 5,0.The problem is that the new formulation become trouble at 21-22°C. Our original formulation (with katon), become trouble < 10 °C. What happens and what can I do to resolve this problem?Thanks!
