You could add some cooling agent. We are using Menthyl Lactate or Menthyl Ethylamido Oxalate in our toothpastes.

Thank you for your comments. We do not heat the mixture during the production. I tried different mixtures of pearlizing agents with no result.

It is liquid laundry detergent with pH 8,5. The same pH with nice pearlizing effect and without it. We are using SLES, cocamidopropyl betaine, potassium soap, lauryl glucoside, ethoxylated alcohol, enzymes, parfume, preservative.

Thank you for your comments.

I am using AkypoSal. It is mixture of glycol distearate, SLES and cocamide DEA. Glycol distearate did not precipitate at the bottom. The pearlizing effect just dissapeared after few days. Any other idea?

[MartinaM]

Thank you for your comment. It is used as a thickener in a soap based formulation. Would you recommend me any other raw material?

[MartinaM]

Thank you for the information.

So there is no chance to lower the pH using any other soap in the formulation.

Thank you for your comment johnb.

The concentration is high, I used 15-25 % of the carbonate. The reason I chose lauryl glucoside is separation of the other surfactants. The solution is homogenous, but I am not sure if it will change.
Other surfactants were precipitated or separated after few hours.

Thank you for your comments. Our customer is Dental clinic so it is possible that I can use this higher level of the Calcium Peroxide. I will check it.
