Delivering actives
When trying to deliver actives to the skin is there a difference between an emulsion and (for example) a toner? Don’t want to use expensive actives at high levels if it’s not gonna be beneficial in the formula.

By toner I guess you mean a solution? Whether you use a solution or an emulsion depends on the nature of the active. Water soluble ones would be fine in a solution, oil soluble ones would be better from an emulsion.
But the answer also depends on what active ingredient you are talking about and what is the specific benefit you are trying to achieve. -
The proper answer to that question is what multinational cosmetics companies strive to know…

Thanks for your input.
@Perry: Yeah, an aqueous solution where the active is a water soluble salicylic acid powder.
@Belassi: Even if they did figure that out I doubt they would use the amount necessary to achieve any benefit. -
Where did you find a water soluble Salicylic acid powder? I am not doubting you. It is just that usually Salicylic acid presents many issues regarding using the proper solvent and generally water solubility is unfavorable. I use a lot of an encapsulated version (Salspheres from Salvona) but it is much more expensive than Salicylic acid and a solvent.

Guess she talks about sodium salt which has good solubility but not salicylic acid really.

Found it at Skin Essential Actives.
