Cosmetic Formulation Chemistry: The Science Behind Every Cream, Serum, and Bottle

Why does one moisturiser feel weightless while another goes greasy within minutes? Why do two "natural" serums behave completely differently on skin? The answer is chemistry, and this book teaches you to actually see it. Cosmetic Formulation Chemistry takes you inside every product category on your bathroom shelf: emulsions, silicones, surfactants, preservatives, retinoids, sunscreens, and more, explaining the real mechanisms behind why a formulation works, fails, or irritates skin. Written for formulators, estheticians, product developers, and anyone who wants to read an ingredient list with genuine understanding rather than guesswork, it assumes no prior chemistry background. Each chapter builds a specific piece of working knowledge: how HLB values guide emulsifier selection, why petrolatum has outperformed newer occlusives for over a century, what actually happens inside a retinoid conversion pathway, and how to diagnose a failing formulation by its symptoms rather than starting over by instinct. Inside you will find: - 32 chapters covering every major cosmetic ingredient category- Diagrams illustrating emulsion structure, skin barrier function, UV filter mechanisms, and more- A stability testing and troubleshooting framework organised by symptom- A full regulatory chapter covering INCI naming, claims, and global cosmetic law- A glossary of core formulation terms for quick reference 212 pages, 6x9 paperback, black and white interior with technical diagrams throughout. Stop guessing what is actually in your skincare. Start understanding it.
