Are you aware on how to form an emulsion? I am asking because I have noticed some unusual questions in different threads you started like oil and water ratio related to BTMS amount. BTMS is the easiest emulsifier I have ever worked with. It was the first emulsion I formed before I had an appropriate mixer, using a small hand whisk and a bowl. 1.5 years later, that small batch has not separated.
I am sorry to say that you are missing some crucial info and research. I recommend swiftcraftmonkey’s blog. She is great for introduction to certain concepts and she does have some formulations for you to follow (some with BTMS).
And I use 2-5% BTMS-50 in formulations.
