What is the term for active ingredients in pure form?

1. Formulations

2. Technical grade

3. Concentrates

4. Emulsions

The correct answer is: Technical grade

The term for active ingredients in pure form is technical grade. This designation refers to the chemical substances as they are synthesized or isolated, typically requiring little to no additional processing or formulation before use. Technical grade substances are often used as a base material in the development of agricultural products, pesticides, or other chemical formulations. In contrast, formulations are products made by mixing technical grade materials with other components to create a final product suitable for application. Concentrates indicate a form that has a higher concentration of active ingredients but may still include other substances. Emulsions refer specifically to a mixture of liquids that do not normally mix, like oil and water, often used as a method for delivering active ingredients in certain formulations.
