Cosmetic formulation guide

Guide to Formulating Natural and Conventional Cosmetics: clear explanations of key concepts, practical examples, IFRA fragrance guidelines, and ingredient compatibility tables. All essential regulatory information (concentrations, ingredient permissibility, COSING) — in one place.

Why this guide?

To give you a clear, safe, and actionable framework for formulation — whether you choose a natural or a conventional approach. In this guide, you will:

Understand key concepts (emulsifiers, polymers, gums, solubilizers) through simple explanations and typical dosage/pH ranges.

Move from theory to practice with formulation examples and mini-experiments that encourage creativity and hands-on learning.

Compare natural vs. conventional approaches: advantages, limitations, and typical ingredient substitutions (preservatives, emulsifiers, antioxidants).

Apply IFRA guidelines: how to read categories and safely dose fragrance compositions and essential oils.

Check ingredient compatibility: solubility (oil/water/alcohol), “do not mix with…”, and stability (pH, viscosity, electrolytes).

Save time with concise regulatory information: recommended concentrations, ingredient permissibility, and links to the relevant sources.

Get community support: space for your notes and questions, plus a final consultation — the best formulas are created through dialogue.
