Shampoo with Salicylic acid saponin Coaltar 9g Salicylic acid 9g lactic acid 9g Shampoo simplex ad 300g

with Conforma shampoo simplex I get a white precipitation (probably salicylic acid). Is This shampoo of Conforma usable for this preparation provided that the addition of Cetomacrogol 1000 or is this only with the original shampoo simplex NF?

Answer

I think it should succeed, although I do not know which tensids are used in this composition. And the solubilizing capacity of all the tensids is not the same. I believe that this shampoo from Conforma is also visceuzer as the simplex from the NF.
I would start with the addition of 20g Cetomacrogol 1000. An increase in viscosity, which follows, can be compensated by the decrease due to the added lactic acid.
