Hey, In My opinion, Sodium benzoate works below ph 5. So good to go with Methylisothiazolinone & Methylchloroisothiazolinone with 0.01%.

@nishil113 I want to point out first that I’d be better not to use Cocamide DEA along with Bronopol, since ingredients which have free secondary amines (like Cocamide DEA) shouldn’t be mixed with nitrosating agents (like Bronopol). Also, even though cationic surfactants can be added in small amounts to anionic solutions (phase diagram has a zone in which this mixture doesn’t form precipitates), check during stability if there is no sign of turbidity. And lastly, you have a too high amount of Vitamin E for a rinse-off product.

So, regarding your question, it’d be more helpdul to understand what do you mean for harder. Does it make your scalp itch? If that’s the case, you might be sensitive to either SLES or CAPB. I’d try first replacing part of the SLES for a milder surfactant (like a carboxylate).  

Hey Friend!!

Thank you for the help.

I have tried once by removing glycerin and bronopol from the formulation. Also i have reduced Vitamin E percentage by 0.2%. 

By doing this i have recoverd by 50%.

Glycerin kills the foam and doesn’t provide any real benefit in the product. It is water soluble and simply washes down the drain. So, all negative no positive - no reason to use it.

Hey Perry,

Thanks a lot for support.

I have tried as you suggested. We have removed glycerin from formulation and bronopol from the formulation. Now problem is solved by 50%.
