Ingredients

This section details how Ingredients in TPD PRO serve as reusable components with toxicological data, forming the foundation of product Compositions.

What are Ingredients?

Ingredients in TPD PRO represent all individual chemical substances used in the formulation of e-liquids or other tobacco-related products. Each Composition (liquid formula) is made up of multiple Ingredients, and each Ingredient must be declared in EU-CEG submissions.

TPD PRO provides a powerful and reusable Ingredient Repository, allowing users to manage, reference, and validate ingredients efficiently across multiple products.

Key Features of the Ingredient Module

  • Centralized database of ingredients used in compositions

  • 200+ preloaded common e-liquid ingredients, complete with CAS numbers and toxicological data

  • Manual addition of custom ingredients

  • Search, sort, and filter ingredients for quick access

  • Reusable across multiple Compositions and Submissions

How to Add an Ingredient

  1. Navigate to Ingredients in the left-hand menu

  2. Click “Create”

  3. Enter the following required information:

    • Name — Common or chemical name of the ingredient

    • CAS Number — Unique Chemical Abstracts Service number (e.g., 57-55-6 for Propylene Glycol)

    • Function — Role in the composition (e.g., flavor, solvent, base)

    • Toxicological Profile (optional)

    • Additional fields (e.g., supplier, REACH data, if available)

  4. Click “Save”

✅ Once added, the ingredient becomes available in the Composition builder and can be used repeatedly.

Reusability

  • An Ingredient is created once and then reused across any number of Compositions

  • If you update an ingredient’s data (e.g., CAS number correction), the change is reflected in all future Compositions, but not retroactively in submitted ones

Best Practices

  • Always double-check CAS numbers for accuracy

  • Use consistent naming conventions for clarity (e.g., "L-Menthol" vs. "Menthol")

  • Group ingredients by function or volatility for better management

  • Avoid duplicating ingredients with slight name variations — search first before adding
