Abstract
The invention provides a solvating system for the removal of biofilms which solvates the extracellular polysaccharide matrix holding it to a surface. The aqueous solvating system comprises water, a metal ion sequestering agent, and a solvating agent for an extracellular polysaccharide matrix, which is gentle enough to be used directly on human tissues, but which may also be used on hard or soft non-tissue surfaces to breakdown, and/or remove biofilms.
