So these are added into a formulation to enhance the efficacy of the active ingredients.

It's just called other ingredients, and they often are the bulk of the formulated product.

The chemical in question is known as an organosilicone surfactant.

Fine inner colleagues fed the chemical to honeybee larvae over time

and exposed them to a cocktail of common beehive viruses.
