My dishwashing liquid get a little nontransparent at 5 centigrade
Hello,
I am trying to make dishwashing liquid, but I have a question.
1- I put the dishwashing liquid in the fridge at 5 degrees centigrade it turns a little nontransparent (not opaque). But, the dishwashing liquids in the market at the same temperature are still clear. when the temperature gets to increase my dishwashing liquid gets clear again.
what is the problem in my formulation?
formulation
LABSA 10.3 %
caustic soda (99%) 1.12 %
triethanolamine 0.65
SLES 4%
cocamide diethanolamine 2%
cocamidopropyl betaine 1%
Sodium bicarbonate 0.1%
Urea 0.5 %
sodium chloride 0.4%
Fragrance 0.2 %
pH= 7.5
appearance = clear yellow

Bring the pH closer to 8.5-9.0. It that doesn’t work, chances are your system is too sensitive to sodium chloride. You can reduce LABS and increase your SLES.

Actually I think I am controlling the cloud point of Labsa. I guess it happens because of cocamide dea. I am not sure a bout that. When I reduce cocamide dea the viscosity decrease. I can increase the viscosity with other ingredients but the product is not affordable.

Try removing Sodium chloride, and increasing viscosity only with either Cocamide DEA or CAPB.

I will try to remove the NaCl and let you the result of the test.
I tried to reduce the Labsa and Increase Cocamide dea and Betaine. The dishwashing liquid turns into a little nontransparent at 9 degrees centigrade.

Maybe it’s not a great problem - if only a little nontransparent at 5C that resolves when warmer. What will be the chances of consumers using/seeing it at 5C and will they be put off?
