This terminology is widely used in both professional and educational settings within the beauty and personal care industry, particularly in relation to their use as disinfectants and antiseptics. The term "quats" helps practitioners easily reference these compounds, which are known for their effectiveness in killing bacteria and viruses, making them popular in various formulations.

The other terms provided, while related, are not as precise or commonly accepted as a general reference for quaternary ammonium compounds. "QACs" is a more technical term that stands for quaternary ammonium compounds but is less commonly used in everyday language. "Quads" is not recognized terminology in this context and can lead to confusion. "Antiseptics" refers to a broader category of substances that inhibit the growth of microorganisms, which may include quats but does not specifically identify them. Therefore, using "quats" is the most accurate and recognized way to reference quaternary ammonium compounds in relevant discussions.
