Synergistic reactions, also called synergistic effects, are a type of chemical reaction where the combination of chemicals produces effects stronger than the chemicals would ever produce alone. Synergistic reactions essentially magnify the power and potency of chemicals. These reactions may be dangerous, particularly when they involve potentially toxic substances such as alcohol.
Chemical reactions occur when at least two substances combine to form a single new substance. Chemical reactions occur on a daily basis and in many environments. Chemical reactions involve synthetic and natural substances, and may have different effects. While synergistic reactions generally cause harmful reactions, other chemical reactions called antagonistic effects produce neutral reactions.
