Abstract
A non-toxic enzymatic detergent for use in cleaning surgical instruments and the 1 like which have a large build-up of bio-residue thereon and which need specialty cleaning in order to avoid both hardened bio-residue and certain fluid traces from the instruments for both operating accuracy as well as sterilization requirements.
Claims76
A non-toxic and environmentally safe enzymatic cleanser for cleaning of medical equipment and instruments which have bio-residue thereon, said non-toxic cleanser consisting of the following components,
- water,
- sodium formate,
- sodium tripolyphosphate,
- sodium xylene sulfonate,
- alkoxylated isopropanolamide
- protease enzyme, and
- amylase enzyme (660) and, optionally, fragrance, calcium chloride,
- propylparaben, methylparaben, propylene glycol or HRE 40, sodium borate decahydrate, laurel alcohol alkoxylate (Dephypon E 124-90) and fatty alcohol Alkoxylated nonionic Surfactant (Dephypon LS 54).

- a solvent,
- an enzyme stabilizer for removing trivalent metallic ions,
- a buffer to keep the solution pH near 11 and for removing metallic oxides,
- carbonates and sulfides,
- a hydrotropic nonionic surfactant,
- a compound to remove protein based materials,
- and a compound to remove carbohydrate based materials.
A method of making a non-toxic cleanser for equipment and instruments which have bio-residue attached thereto, said method comprising,
- adding and mixing the following ingredients as Phase I
- a solvent,
- Calcium Chloride
