Benefits of technology

The direct incorporation technology provides benefits over coating technologies by making the product more durable and eliminating the need for a coating step during manufacturing.

Problems solved by technology

The presence of “heavy metals” in products that may eventually leach into the environment either during use or after disposal of a treated product have become an issue of concern for environmental policy and regulators and others that strive to influence consumer markets.
These chemistries can be temperature limited, sensitive to UV degradation and are expensive to use when the entire mass of an object is to be treated.
In addition, many have dangerous toxicity profiles and can cause undesirable side effects that can affect the aesthetics of a treated article.

example 1

[0033]Initial work focused on three GRAS chemistries, the salts of benzoic acid, sorbic acid, and citric acid. FIG. 1 shows a TGA plot of these salts that indicates all salts are thermally stable to temperatures greater than 300° C.

[0034]In FIG. 1, the TGA Plot at 10° C. / min showed volatization of GRAS salts up to 275° C. The sorbate and citrate salts were stable (did not lose any mass) to temperatures greater than 275° C., while the citrate was approximately 10% water which is why it lost approximately 10% weight then leveled out—the salt itself did not volatize. This thermal stability and reported antimicrobial efficacy made these compounds seemingly ideal for this application.

[0035]Each salt chemistry was evaluated by compounding into a polyolefin carrier at 10% concentrate level, then using that polymer concentrate as a masterbatch to injection mold PP plaques at various end-use levels for testing. Commodity PP and EMA materials in a twin-screw extruder for compounding, and in a...

Abstract

A composition and method for microbial control on a material surface using a minimum risk pesticide such as a GRAS antimicrobial / preservative component. The GRAS antimicrobial / preservative component is preferably an organic acid.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from U.S. Provisional Patent Application No. 62 / 955,161, filed on Dec. 30, 2019, and U.S. Provisional Patent Application No. 62 / 955,155, filed on Dec. 30, 2019, in the United States Patent and Trademark Office. The disclosures of which are incorporated herein by reference in their entireties.FIELD OF THE INVENTION[0002]The invention relates to a composition and method for microbial control on a material surface, more particularly to a composition and method for microbial control on a material surface using a minimum risk pesticide.BACKGROUND OF THE INVENTION[0003]Microbial control on material surfaces can be achieved through the incorporation of antimicrobials into a base material. Current practice relies heavily on the use of metal containing actives such as silver, zinc and / or copper. The presence of “heavy metals” in products that may eventually leach into the environment either during use or after disp...
