A multi-purpose cleansing, debriding and disinfecting agent for the management of acute and chronic otitis externa. Also, routine use helps maintain a healthy ear canal. The hydroxy acids lower the pH of keratin and wax, so allowing better absorption of water. This allows waxy and necrotic debris to be easily removed and this, combined with the associated germicidal and antifungal action, promotes a healthy tissue environment. Assists tissue healing by separating dead from underlying granulation tissue and by inhibiting bacterial growth. Also promotes the healing of wounds and abrasions, especially where infected and necrotic tissue is impairing tissue repair processes.
