Cosmetic Formulation Science: DIY Apothecary

The science behind making your own cosmetics — without the guesswork. Cosmetic Formulation Science teaches you the foundational principles that turn a kitchen experiment into a stable, safe and effective product.

Inside:

• The chemistry of emulsions — how oil and water actually come together
• pH balancing, natural preservation, and why both matter
• Ingredient ratios for creams, balms, serums, oils and butters
• A clear glossary of common cosmetic ingredients and what they do
• Safe practice and labelling basics for at-home formulators

For the maker who's outgrown "recipes from the internet" and wants to understand what's actually happening in the beaker.
