For WHITE GMS (CP) stick the mold in the fridge over night to prevent gel. You don't need TD.
Compare to TAN (CP or HP) GMS where you cover and insulate with old towels or a blanket to insure gel -- which, btw, intensifies whatever color you use.
ADVICE: Embrace the tan. Customers do. Not using colorants improves the profit margin, not to mention all the T & E you are likely to experience "getting it right." Better to spend the time and $$ focused on fragrance. Fragrance sells!!!
OPTION: I sometimes use white Kaolin clay to lay down a white foundation for the colorant ( )
The only time I use TD is to make sunscreen! But that's just me. Not a fan.
Awesome advice. Thanks!
