About this course
Have you ever wondered how your favorite skincare and personal care products are developed from scratch? Transitioning from a curious consumer to a knowledgeable formulator requires a solid understanding of the science behind cosmetic ingredients and how they interact.
This text-based course guides you through the core principles of cosmetic chemistry, raw material selection, and formulation math. You will gain the confidence to analyze product labels, understand the roles of different ingredients, and design balanced, safe, and stable cosmetic formulations on paper.
What you'll learn:
- Understand the essential roles of surfactants, emulsifiers, preservatives, and rheology modifiers in cosmetic products.
- Calculate precise ingredient percentages and mass balances for accurate formulation scaling.
- Select safe and effective ingredients based on skin compatibility, stability, and modern clean beauty standards.
- Evaluate Hydrophilic-Lipophilic Balance (HLB) values to choose the right emulsifiers for stable emulsions.
- Apply sustainable practices by identifying biodegradable, upcycled, and green chemistry alternatives.
- Document formulations professionally using standard laboratory notebook conventions and safety guidelines.
The course begins with foundational definitions and cosmetic chemistry basics before moving into raw material categories and quantitative formulation design. You will progress through written case studies and step-by-step formulation exercises that reinforce your practical understanding of product construction.
This course is designed for absolute beginners, aspiring cosmetic chemists, indie beauty brand founders, and skincare enthusiasts with no prior scientific background.
