Best pH for viscosity SLS + CAPB?
I am trying to achive the best viscosity with the lowest input of SLS and CAPB?
Best pH would be about 5,5?
I have noticed I can thicken the formulation by just simply adding more salt or for example sodium sulphate (up to 5-8% if SLS and CAPB input are low).
Do you have other suggestions what other ingredient I could add to boost the viscosity? All the natural gums unfortunately limit the foam 🙁
