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.
