A halogen scavenger contains as an effective ingredient an aromatic compound which has a resonance-effect-relying electron donating group as a substituent. The aromatic compound is constituted, for example, by an aromatic ring such as a substituted or unsubstituted benzene, naphthalene, anthracene and pyridine ring, and at least one group (a resonance-effect-relying electron donating group) which contains a lone-pair-containing hetero atom, such as an oxygen, sulfur or nitrogen atom, adjacent to the aromatic ring.

Halogen scavengers

A volatilization suppressing agent comprising at least one thermosensitive polymer as an effective component is disclosed. Also disclosed is a volatile composition comprising a volatile effective component or an effective component carried by a volatile solvent and at least one thermosensitive polymer are disclosed. The use of the volatilization suppressing agent can suppress volatilization of volatile components when temperature rises and, as a result, volatilization of the volatile components is less affected by the temperature change. It is therefore possible to volatilize volatile components from air fresheners, deodorants, insecticides, moth proofers, repellents, attractants, antimicrobial agents, antifungal agents, antioxidants, and ozone decomposition agents more economically and to prevent troubles due to excessive volatilization.
