Discover what’s really inside the oils and butters used in cold process soap-making. In this post from The Clean Chemist, we break down the molecular structure of oils—specifically triglycerides, glycerol, and fatty acids—to explain how they transform into soap through saponification. Learn how different oil compositions affect lather, conditioning, and cleansing, and why we choose sustainably sourced ingredients like RSPO Certified palm oil. Perfect for soap enthusiasts, ingredient-conscious consumers, and anyone curious about the science behind their skincare.
