Eastman™ Ester Gum 15D-M kosher is recommended for use as an ingredient in chewing gum which complies with the requirements and specifications established by FDA of the United States (FDA 21 CFR 172.615) and with the specifications for chewing gum resins of Europe (Food Chemical Codex edition V).
Resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse affect on the solubility of the resin in organic solvents or in its compatibility with polymers. Accordingly, it is recommended that strict control of inventory be observed at all times, taking care that the oldest material is used first.
Eastman™ Ester Gum 15D-M kosher will remain within product specification limits as mentioned under the heading "Product Specifications", for a period of 1 year from production date and if storage conditions outlined in this data sheet are observed.
However, as we can neither anticipate the conditions under which the resin is processed nor the end use applications for which is used, we recommend that the material be tested upon receipt.
