Consumer Electronics Company Makes Hazard Assessment Process Faster Through Evalueserve’s Robust Documentation Mechanism

An American multinational technology company was faced with a growing number of polymers, dyes, pigments, UVCB, and other complex chemicals. The sheer volume of these chemicals involved in the product life cycle resulted in the client needing to perform chemical safety assessments with respect to environment and human exposure. However, this proved to be a challenge for the client since there was a huge amount of chemicals lined-up for assessments, with most of the chemicals data scanty.

This demanded a SAR-based hazard assessment, which would be extremely time consuming for the client. In order to help make the client’s hazard assessment process faster and more efficient, we introduced a robust documentation mechanism that combined the knowledge of domain experts with the power of technology.

Our team took a collaborative approach to this challenge by having our toxicologist and chemists work in close collaboration to tackle this huge task.

Phase One: Divide and Conquer

Chemists inferred suitable analogs for data scanty chemicals, toxicologists conducted robust literature searches on the chemical of interest as well as its analogs, followed by data evaluation and analysis.

Phase Two: Authoring Hazard Assessments

On the basis of good quality direct data on chemicals of interest in conjunction with analogs data (in case of data gaps), the hazard assessment covered the determination of endpoint specific hazards (Genotoxicity, Skin Sensitization, RDT, DART, etc.), identifying appropriate POD, and the determination of hazard value (RfD, RSD, VSD, NSRL, etc.).

For environmental safety, the environmental fate of the chemical determined, and environmental PNEC for different environmental compartments, was calculated.

Phase Three: Making the Hazard Profile Robust

In silico prediction of chemical toxicity was integrated into the assessment wherever needed, to help make the overall hazard profile more robust.

Our team delivered a robust mechanism for documenting the safety assessments that were in line with regulatory standards ensuring the safe use of chemicals to the client. Due to the integration of alternative methods (such as using data from like-substances and in silico tools), the client was able to void animal tests. The collaboration of our multi-disciplinary experts such as pharmacologists, environmental toxicologists, human toxicologists, and chemists made the overall hazard assessment process faster and more robust.
