VETSENSE OTIDERM is a wound cleaner, by removing dead cells and encouraging healing in horses, dogs and cats when necrotic tissue, coagulum, debris or wax is present. VETSENSE OTIDERM aids in the removal of dead tissue and embedded debris by causing maximum differential swelling between living and dead areas. This is achieved in two ways; - Low pH causes separation of collagen molecules by rupturing the hydrogen bonding. The optimum pH to achieve this effect is between pH2 and pH3. - The organic acids react with carboxyl and amino groups in the collagen. The insertion of the organic acid forces the collagen chains apart. In both cases, the devitalised tissues absorb water and swell. Healthy tissues are unaffected because of natural barriers to the organic acids and sufficient buffering capacity to maintain a near neutral pH.
