PHTHALIC ACID

Phthalic acid is used in synthesis of dyes and dyestuffs, in medicines and perfumes, phenolphthalein, phthalmide, and anthranilic acid (Lewis, 1996).
Phthalic acid esters have also been used as plasticizers in many products (Bauer & Herrmann, 1997; Magill-Cuerden, 1996).

FORMS

Phthalic acid is a crystalline solid (Lewis, 1996; RTECS , 1999).

-CLINICAL EFFECTS

GENERAL CLINICAL EFFECTS

No data are available about possible systemic effects of phthalic acid ingestion. Irritation of eyes, mucous membranes, and skin have been reported.

-FIRST AID

FIRST AID AND PREHOSPITAL TREATMENT

DILUTION -

If no respiratory compromise is present, administer milk or water as soon as possible after ingestion. The exact ideal amount is unknown; no more than 8 ounces (240 mL) in adults and 4 ounces (120 mL) in children is recommended to minimize the risk of vomiting (Caravati, 2004).
USE OF DILUENTS IS CONTROVERSIAL: While experimental models have suggested that immediate dilution may lessen caustic injury (Homan et al, 1993; Homan et al, 1994; Homan et al, 1995), this has not been adequately studied in humans.
DILUENT TYPE: Use any readily available nontoxic, cool liquid. Both milk and water have been shown to be effective in experimental studies of caustic ingestion (Maull et al, 1985; Rumack & Burrington, 1977; Homan et al, 1995; Homan et al, 1994; Homan et al, 1993).
ADVERSE EFFECTS: Potential adverse effects include vomiting and airway compromise (Caravati, 2004).
CONTRAINDICATIONS: Do NOT attempt dilution in patients with respiratory distress, altered mental status, severe abdominal pain, nausea or vomiting, or patients who are unable to swallow or protect their airway. Diluents should not be force fed to any patient who refuses to swallow (Rao & Hoffman, 2002).

EMESIS/ NOT RECOMMENDED -

Emesis is not recommended because the irritant potential outweighs the risk of systemic effects resulting from ingestion.
