Carbon-14 analysis plays a key role in distinguishing ingredient sources by providing proof whether the material tested is truly derived from natural biological material. Such analysis is useful in the trend toward naturally sourced, plant-based ingredients in the dye market, which sees a growing consumer preference for naturally sourced inks.
Despite the growing trend, some manufacturers still use petrochemical synthetic dyes as they cost less to produce. To prove otherwise, manufacturers submit samples for carbon-14 testing.
Since all living or recently expired material contains a known level of the radioactive isotope carbon-14 while fossil fuel-derived petrochemicals do not contain any carbon-14, the testing result indicates the percentage of naturally sourced versus fossil-derived components in a sample.
Biobased content testing laboratory Beta Analytic uses Accelerator Mass Spectrometry (AMS) to measure the carbon-14 content in a given sample. AMS results of ink ingredients are reported as “% biobased carbon content” to reflect the biomass-based portion of the ink.
