    SLES-2 or SLES-3 both have milder irritancy profiles than SLS. Reverse the ratio. Adding CAPB will help mollify too: good idea. Should thicken up your solution also, if that is OK.

    You can add 1% CDEA ! It has a very good irritation potential and foaming capacity . Today I made a batch with NaOH and Acid Slurry and added CDEA . It is working fine . I used urea instead of NaCl . NaCl makes it harsh .

    @AZiz:while Salt is used to improve the Viscosity, some formulators use Urea. What is the purpose of using Urea here?

    Urea is cleaning agent , as well as it increase viscosity . You may do some research by a small quantity of your liquid and urea . You may also compare NaCl and Urea separately for their harshness and irritation .
