Insolence is defined as the quality or condition of being insolent, which means contemptuously rude or impertinent behavior or speech. It is a negative trait that is generally not desirable. There are no specific ingredients or materials associated with insolence.
It is worth noting that in the context of a product, the term "inert ingredient" may be used. Inert ingredients are components that do not affect product efficacy or performance. However, this is a different term with a different meaning and is not related to insolence.
