  PALMITIC ACID        0.5%
  LAURIC ACID            12.5%

  Use only fatty acids whose derivatives are soluble.

  I have found order/method of addition has a profound impact on stuff like transparency. Coco betaine is a common culprit for this too.

  In addition to finding the right ingredients I would definitely try adding things in at different times, temperatures, etc.

  Did you check your product’s pH? I dont think it is around 9-10, but more than 10 or even 11. Because the KOH concentration is too high (with my calculation of KOH purity is 90%).

  Soap-base is very easy to thicken.
  1. Add NaCl
  2. Add amphoteric surfactant (eg, Lauryl Hydroxysultaine). Do not you Cocamidopropyl Betaine because high alkaline will break amine bond and release NH3.
  3. Nonionic surfactant, such as Decyl Glucoside. Or with even better, Cocamide DEA, Cocamide MEA, Cocamide Methyl MEA,…

  I have no experience using Coco-betaine. Can you remove it and make the formula again, if the same phenomenon occurs, then it is not because of this ingredient.

  Besides, the fatty acid soap in your fomula is soluble (with these percentage), increasing Palmitic acid might cause crystallization at low temperature upon storage.
