What was the formula or just the ingredients you used?? 

That isethionate would be fine! It’s usually what you mix it with & pH that turn it opaque or white!! 

Did you use any aloe Vera? 

Hello Dr.,

thank you for your reply. Frankly, I was just trying to mix water, SCMI and CAPB. I just wanted to see how it goes. From top of my head, I used 8% SCMI and 4% CAPB. I did not even bother with any preservative. (I’m aware it may have an impact later on the formula.)

Next day I was trying add Glycerin and I adjusted SCMI to 10% and kept CAPB at 4%. Glycerin 5%. It barely thickened at all. So I guess I will need to play with the inputs of surfactants. 
And also check and adjust the pH. Althought, I would never imagine, it would go lower than 6 by itself.
