BTMS-50 to silicones ratio?

How much silicones can BTMS-50 emulsify?

I've tried a 1:1 ratio (equal amounts of BTMS-50 and dimethicone) and it held fine.
Some say it works fine at a 1:2 ratio (twice as much silicones as BTMS-50), especially if some of them are cyclomethicones.

Sorry if this has been asked before. Can't seem to find a proper answer anywhere, not even in the Croda website.

  • This Cosmetic and Toiletry Formulations 4 formula uses almost 3x silicone as BTMS.
    But it's just BTMS, not BTMS-50 with butylene glycol.
