Formulation Deterministic: VOC and concentration-limit arithmetic Gefahrstoffmanagement, product stewardship, formulation chemists
Reason over a whole recipe object — not a single molecule — to roll up VOC content and produce a preliminary CLP mixture hazard view.When it applies: you need a fast, traceable screening pre-check of a multi-component formulation before a formal, human-signed classification.

Scenario

Reason over the whole recipe object — components and weight fractions — rather than a single molecule, demonstrating that the platform understands formulations, not just structures.

Worked example. A waterborne or solvent-borne coating recipe, given as components plus weight percentages.

Agent workflow

  1. Read components and weight fractions from the recipe.
  2. Deterministic roll-up — VOC content per the 2004/42/EC definition, plus a flash-point / physical-property estimate from component data.
  3. Screening CLP mixture classification — apply component classifications with generic concentration limits and M-factors to produce a preliminary mixture hazard view.

Demo output

Recipe in → VOC value plus preliminary hazard flags out, with every number traceable to a specific component and rule.

Honesty line

This is a screening / pre-check, not a legally binding CLP determination. The engine does the arithmetic and shows its work; the human signs off. Over-claiming legal classification is exactly what a weak vendor would do — so the platform does not.

Deterministic vs LLM

  • Deterministic — VOC and concentration-limit arithmetic.
  • LLM — explanation of why a given flag fired.

Data sources

  • Native (offline): CoolProp (thermophysical properties of known fluids); RDKit.
  • Public reference layer: CLP Annex VI Table 3 (harmonised C&L); ECHA C&L Inventory; generic/specific concentration limits and M-factors (CLP Annex I/VI); the 2004/42/EC VOC limit table.

Limits

Mixture classification is a screening, not a binding determination. It is a starting point for a qualified human assessor.
