Your formula's ratio is not too bad. But Im not sure why you have to try free/thraw storage? That one is only for stability test (which is at extreme condition). For other ppl comment about emulsifying effect of Centrimonium Chloride, yes it can be…

(Quote) Hi. The yellow color issue comes from complex formation of Piroctone Olamine and Ferric (only 1ppm of Ferric can result in this discolouration). Im not sure whether the complex affect antibacterial effect of Piroctone Olamine or not…

Body soap can be alkaline or weak acid type. Shampoo should be in weak acid or acid pH in order not to disrupt your scalp barrier function. In shampoo, we also add Polyquarternium-10 or Guar Hydroxypropyltrimonium Chloride for coating hair after cl…

PEG-7 Glyceryl Cocoate is the only superfatting agent in your formula from my view. I just suggest to remove PEG-40 Hydrogenated Castor Oil and Polysorbate 20 in order to confirm the cause of your formula color change. (in some case color change is …

They are from each surfactant, not from whole formula.

There any many choices for you such as these below secondary surfactant: Cocamide DEA, Cocamide Methyl MEA, Decyl Glucoside,... Or thickener like Hydroxypropyl methylcellulose. Increase amount of surfactant if degreasing power is not enough.

I suspect the cause is due to Hydrolysis of Polysorbate 20 and PEG-40 Hydrogenated Castor Oil. I have experience with PEG-80 sorbitan laurate that will undergo hydrolysis and change color to yellow even at room temperature.

I find on your picture that Coco Glucoside and/or lamesoft amount is too high, isnt it? Can you try to remove it and check sedimentation again?

When talking about face wash cream type, the first thing is that your surfactant concentration must be high in order to thicken the cream. Then, during neutralization process, soap gel (aka lamellar gel) will appear which entraps alot of tiny bubble…

With these 3 surfactants, you can make any kind cleanser that you want. The point is that you will find it difficult to control the feel and viscosity of your product with just these 3 materials.

Removing caprilic/capric triglycerides and it will be solved. This ingredient is oil and will separated overtime.

With my product and my experience, they can work well together.

Add small amout of emulsifier and ask user to shake upon using. Oil and water mixing will provide natural white color (temporary) for you. Also, removing Titanium Dioxide is better as its particle is too big for foam dispenser.

What is the viscosity of your cream? The silicone content seems to be too high for 3.5% ceteareth-20 to work well. My addition opinion is adding bulky ingredients like Meagnesium Aluminium Silicate for enhancing viscosity (indirectly boosting stabi…

ALS will release NH3 at high pH. Please check your pH if it is higer than 5.5. Also, please use pH buffer for stabilizing the product.
