Increase the viscosity with sodium chloride
When you exceed the amount of salt in products you wash to increase the viscosity, it can become very cloudy, is this normal? or could it be something else?

I’d be better to know what’s in your formula, but some polymers can coil due to the high amount of salts, reducing transparency.

Thank you very much for you. Let me tell you that I have a total of 15% active surfactants
Phase A:
Water
Disodium EDTA - 0.2%
polyquaternium 7- 2%
Phase B:
sodium laureth sulfate 8% Active,
sodium lauroyl sarcosinate 2% Active sodium cocoyl glutamate 2% Active, disodium cocoamphodiacetate 2% Active, cocamidopropyl betaine 1% Active.
Phase C:
Propylene glycol 2%
Fragrance 0.5%
Phenoxyethanol and Ethylhexylglycerin 1%
Sodium chloride 0.5 - 2%
In my sodium chloride, it got away, a little over 2%, and became cloudy. I added color to make it look nice, but I wanted it to be transparent.

The system PQ-7/SLES/CAPB is salt sensitive. On your current sample, you could try increasing the SLES or increasing the pH.
To avoid having to use so much salt in your system, you could use more CAPB or a rheology modifier.

Thank you very much, my friend, be well. Now I made it with color and it looks very nice and very good performance.
