Multi-component Formulations Risk Assessments for the manufacture of inks and adhesives


Companies who manufacture inks and adhesives


Small amounts of inks and adhesives used on food-packing or labels may migrate into the food or drink. Occasionally, a consumer may accidentally ingest a small label. Manufacturers need reassurance that any ingested chemicals pose no unacceptable health risks to consumers. Due to confidentiality, manufacturers do not know full compositional details of their products, as they buy components in trade name forms. Having a reassuring, independent bibra opinion on risk gives manufacturers a marketing advantage over companies without such reassurance.

Project Goals

Reassurance that migrating chemicals do not pose significant health risks can be provided by independent, expert toxicologists. Bibra employs experienced, professionally-registered (RSB/BTS/ERT) toxicologists who routinely provide hazard and risk assessment reports for multi-component formulations.


The client provides the contact details of individual suppliers, and describes the intended application e.g. coating weights, surface areas and typical foodstuffs.

Bibra contacts suppliers and obtains (e.g. using NDAs) confidential compositional details of individual components. Generally, it is necessary to contact secondary or even tertiary suppliers.

Bibra estimates potential exposure to individual chemicals, assesses the hazards of the individual chemicals, and carries out risk assessments by combining hazard data with “worst-case” exposure assumptions. Where adequate toxicity data are lacking, it is possible to make use of the Threshold of Toxicological Concern approach.

Project Outcome

Bibra provides independent, expert opinions that are valuable marketing adjuncts for companies selling inks and adhesives to food-contact material manufacturers, and gives reassurance over consumer health.
