What chemicals are in your air freshener?

Because there are currently no regulations requiring manufacturers of household products to disclose the full list of ingredients on product labels, this is anyone’s guess. However, most commercial air fresheners are composed of a toxic mix of potentially dangerous chemicals. These include formaldehyde, hexylene glycol, naphthalene, paradichlorobenzene, phenol, xylene and synthetic fragrance. Three of these are recognised cancer-causing agents and all of them are suspected of triggering asthma and allergic reactions, and also causing harm to internal organs.
