This preparation, containing methansulfonic acid, is used to remove biofilms and necrotic or infected tissues from skin lesions and oral cavity lesions.

Abstract

The invention proposes a preparation suitable for the removal of biological plaques and necrotic or infected tissues from skin and oral lesions, comprising 99.0% methansulfonic acid and a proton acceptor. This proton acceptor is selected from a group including: anhydrous sodium carbonate, 5-amino-2-mercaptobenzimidazole, sodium tetrasodium salt of ethyl diacetic acid, sodium gluconate, sodium tartrate dihydrate, 2-mercapto-5-benzimidazole sodium sulfite, dimethyl sulfoxide, polyethylene glycol 400, polyethylene glycol 600, silicon dioxide, tetraethoxysilane, and mixtures thereof. The preparation described above may be formulated as a solution, gel, or cream.
