@mikethair thank you for this information. Im trying to formulate a shampoo using cocoate sodium that we make inhouse using coconut oil. but the problem is that the shampoo gets milky and unclear at around 20 degree. could you please advice if you have such a problem and also are you using a preservative. the PH is high and most natural preservatives are incompatible with PH >8. thank you.

Not sure why you are using Sodium Cocoate. We use this in solid soap formulations.For liquid shampoo we use Potassium Cocoate (saponified coconut oil).We have zero problems with cloudiness with Potassium Cocoate . No, we do not use a preservative because the pH is around 9.0. Challenge Testing (PET) have demonstrated that preservatives are not required.Plus, this is backed up under ISO 29621:2017 covering finished cosmetic products. Identified products in the guideline do not require preseravtives and the application of microbiological International standards for Cosmetics commonly called “challenge test” or ISO 11930.
