prevents ozone damage
Etymology
'antiozonant' originates from a combination of elements: the prefix 'anti-' (from Greek 'anti' meaning 'against'), the noun 'ozone' (coined from Greek 'ozein' meaning 'to smell'), and the agent-forming suffix '-ant' (from French/Latin usage) to indicate something that acts against ozone.
'antiozonant' was formed in technical English in the 20th century by compounding 'anti-' + 'ozone' + '-ant' to name substances used in rubber technology; it emerged as a specialized industrial term rather than evolving from an older single-word ancestor.
Originally the parts simply meant 'against ozone'; over time the compound came to denote specifically a substance added to materials (especially elastomers) to prevent ozone-induced deterioration.
