Cloud point behavior of dishwash liquid
Following dishwash recipe become clouded below 10 degree temperature and become transparent again( above 20 degree) with some solid mass sitting at the bottom of bottle.
Y question is how we can lower the cloud point upto -10 degree. Most of the time we face winters in my country.Dishwash liquid

@Zabi The precipitate at the bottom if Sulfonate. Sulfonic acid doesn’t actually like NaCl, so the more Sulfonic you use, the less NaCl it can resist. 12% is quite some Sulfonic. Either you cut down your NaCl (try a sample without it), or Replace part of the Sulfonic by SLES. If you want to use that much NaCl, you should cut half the amount of Sulfonic, but it depends on your system, so try with different ratios of Sulfonic/SLES.
