Abstract
The use of aqueous compositions containing at least one chelating agent in the removal of alginates from cutaneous substrates to which they are bound is disclosed. Such compositions, which may also contain physiological salts and non-ionic surfactants, are particularly useful in the removal of alginate wound dressings from human or animal wounds, skin, or cellular tissue.
Claims8
A method for removing an alginate from a cutaneous substrate which comprises:
- A) contacting said alginate with an effective amount of a chelant solution which comprises a) at least about 0.1 weight %, based on the weight of said composition, of a chelant;
- and b) the balance water;
- and B) removing said alginate from said cutaneous substrate.
In an improved method for the removal of an alginate dressing from wound, skin or cellular human or animal tissue, the improvement which comprises contacting said alginate dressing with an effective amount of a composition which comprises:
- a) at least about 0.1%, based on the weight of said composition, of a chelant;
- and b) the balance water.
