US Patent:

20040242746, Dec 2, 2004

Filed:

Mar 5, 2004

Appl. No.:

10/794306

Inventors:

Jon Freedman - Auburn AL, US
William Spano - Opelika AL, US
Deepti Gupta - Auburn AL, US

International Classification:

C09K003/00
C08K003/26

US Classification:

524/424000, 252/194000, 524/425000

Abstract:

A composition comprising a thermoplastic and a COreleasing material; wherein the COreleasing material comprises: a) a carbon and oxygen containing salt of an alkali or alkaline earth metal; and b) an acid; the COreleasing material has a sufficient amount and ratio of the carbon and oxygen containing salt of the alkali or alkaline earth metal and the acid so that, in the presence of water, the COreleasing material reacts to release COgas through the thermoplastic into a surrounding environment.

A01N 25/10
B65D 81/24
B65D 25/14

Abstract:

Disclosed are antimicrobial releasing agents, methods of preparing the antimicrobial releasing agents, and entrained polymers containing antimicrobial releasing agents. The antimicrobial releasing agent is prepared with an acidified hydrophilic material with a pH below 3.5 as a carrier, an active compound, and a trigger. The entrained polymer of the invention releases an antimicrobial agent in gas form, such as ClO, optionally over a range of concentration from 150 ppm to 1800 ppm per gram of the entrained polymer under certain tested conditions.
