adulterant

Impurity added deliberately

An adulterant is a substance added to another to make it impure, typically for economic gain or deception.

Food adulterants might be cheaper fillers or harmful additives; drug adulterants dilute the product or add dangerous compounds: The heroin was cut with fentanyl as an adulterant.

The word implies contamination rather than legitimate blending.
