Toxicological data interpretation and OEL derivation
Toxicity evaluation services interpret laboratory and literature toxicity data to support GHS classification, OEL derivation, and risk-based design. We bridge toxicology, industrial hygiene, and process safety to deliver actionable safe-use guidance.
A structured, facilitated process — from scope definition through close-out — producing defensible, actionable outputs.
Identify toxicity endpoints per ECHA / OECD — acute (oral, dermal, inhalation LD50/LC50), skin/eye irritation, sensitisation, repeated-dose, mutagenicity, carcinogenicity, reproductive; align with REACH Annex VII-X tiered requirements.
Conduct acute toxicity per OECD 401-405 (replaced by 420/423/425), subchronic per OECD 407-408; specify GLP (Good Laboratory Practice) compliance per OECD GLP Principles; align with REACH / CLP / GHS.
Apply in-vitro alternatives per OECD validated methods — skin irritation (OECD 439), eye irritation (OECD 491/492), sensitisation (OECD 442C/D/E); apply QSAR per OECD QSAR Toolbox to reduce animal testing.
Conduct exposure assessment per ECETOC TRA / ChEM / ART; derive Occupational Exposure Limit per ACGIH / DECOS / SCOEL methodology; align with REACH DNEL derivation and OSHA PEL framework.
Design workplace exposure monitoring per EN 689 / NIOSH 1995; specify health surveillance per occupational medicine guidance — biological monitoring, audiometry, spirometry; align with OSHA / EU regulatory programmes.
Compile toxicity dossier with test reports, exposure assessment, and risk characterisation; integrate with REACH dossier, CLP / GHS classification, SDS authoring; align with corporate product stewardship programme.
