Abstract
A method for removing impurities and potentially toxic substances from cellulose is disclosed. The method comprises the following steps: (a) immersing cellulose containing organic extractables in one or more acid baths so as to remove traces of organic extractables; (b) immersing the cellulose in a water bath; (c) immersing the compressed cellulose in an alkaline bath; and (d) sterilizing the treated cellulose using pressurized steam.
Claims7
A method for removing organic extractables from a compressible cellulose such that said cellulose may be used for medical/dental applications comprising the following steps:
- (a) providing a cellulose material;
- (b) immersing the cellulose material containing organic extractables in one or more acid baths comprising a Krebs cycle acid metabolite so as to remove traces of said organic extractables;
- (c) immersing the cellulose material in a water bath;
- (d) immersing the cellulose material in an alkaline bath;
- and
- (e) treating the cellulose material using pressurized steam for a time sufficient to remove all traces of impurities, said method enabling said cellulose to be recompressed and safely used for dental and medical applications.
A method for cleaning cellulose such that said cellulose can be recompressed and used for medical or dental applications comprising the following steps:
- (a) providing a cellulose material;
- (b) immersing the cellulose material in one or more acid baths wherein said acid bath comprises a Krebs cycle acid metabolite;
- (c) immersing the cellulose material in a water bath;
- (d) immersing said cellulose material in an alkaline bath comprising sodium bicarbonate;
- and
- (e) subjecting the cellulose material to pressurized steam for a time sufficient to remove the organic extractables, said method enabling said cellulose to be recompressed for safe use in dental or medical applications.
