I think total fatty acid proportion quite low. I can try to elevate the percentage of stearic acid to 3% or more. Beside that, if pH of your formula is higher than 10, then you reduce the proportion of KOH. Good luck.

I also use saccharides as humectant in cream soap. However, my formulation decreased its viscosity during the time. Saccharides are the cause, aren’t them ?

Sodium soap used for soap bar because of their firm, however, I need soap-based with paste-appearance.

@Fekher It isn’t really, product’s appearance is paste because it’s facial wash.

@Fekher Yes, glycerin play the role as humectant, also solvent in soap-based. I noticed that higher glycerin proportion caused lower viscosity at the first time (when it’s just produced not only for during time). How can I solve this problem because, when I decrease the proportion of glycerin, soap-based become harsh and cause dry skin ?
