In summary, the formulation of bar soap involves a careful selection and combination of various high-quality ingredients, each serving a specific purpose to deliver a product that is not only effective in cleansing but also nourishing and protecting the skin.

Base Oils and Fats

  • Olive Oil: Rich in oleic acid, it contributes to a moisturizing and conditioning lather, providing excellent skin nourishment.
  • Coconut Oil: High in lauric acid, it creates a hard bar with a fluffy, stable lather and imparts strong cleansing properties.
