Abstract
A disposable paper with a slightly abrasive surface impregnated with an iodophor and detergent is an excellent germicidal pre-wash in the surgical scrub routine or in any situation where it is important to impede the growth of microorganisms. By using substantially dry impregnated papers the product may be packaged and stored for at least 18 months without undue deterioration. In the presence of undue moisture, the paper degrades too fast for adequate storage.
Claims4
A single use wet strength paper useful in germicidal cleansing procedures impregnated with a mixture comprising:
- a. a nonionic detergent consisting of condensates of propylene oxide, propylene glycol and ethylene oxide forming a compound having a molecular weight of about 5,000 to about 10,000, about 18 parts;
- b. an anionic detergent consisting of sodium N-coconut-acid-N-methyl taurate, about 26 parts;
- c. an anionic detergent consisting of a coconut-oil acid ester of sodium isethionate, about 1 part;
- d. iodine, about 2.6 parts;
- e. sodium iodide about 1.5 parts;
- f. isopropanol about 5.0 parts;
- g. a weak organic acid, about .2 parts;
- and
- h. water, about 45.4 parts.
A method of preparing a storage stable iodine containing dry paper tissue comprising:
- a. combining water, about 45.4 parts;
- weak organic acid, about .2 parts;
- sodium iodide about 1.5 parts, isopropanol about 5.0 parts, and iodine 2.6 parts in a stainless steel vessel and agitating to obtain a clear solution;
- b. heating a nonionic condensate of propylene glycol, ethylene oxide and propylene oxide, about 18 parts, until melted,
- c. adding slowly the iodine solution (a) to the molten condensates (b);
- d. incorporating water, a sodium N-coconut-acid-N-methyltaurate, about 26 parts, and a coconut-oil acid ester of sodium isethionate, about 1 part, into the iodine combination (c) thereby forming an iodine-detergent composition;
- e. impregnating paper tissues with said composition;
- and,
- f. drying to a water content of less than about 8%.
