Abstract

The bar soap is a cosmetic personal care product most consumed in the world. The incorporation of actives to these products provides greater refinement to the formulation. Oils are incorporated in order to increase the moisturize and hydration of the skin. Stability tests are conducted to demonstrate the product's behavior during its period of validity and are essential when there is development of new formulations. The objective of this work was to produce bar soaps containing pequi oil and evaluate its stability through physicochemical testing. They developed three primary formulations with different pequi oil concentrations (1, 3 and 5% w/w), which were evaluated for strength and absorption to water, durability, melting, foaming, crack formation and pH . The best results were obtained with the incorporation of 3% (w/w) of oil. After determination of the optimal concentration of oil, a new formulation was developed containing 3% of pequi oil and the stability tests were remade. It was found that the soaps showed good stability. Thus, it can be shown that the pequi oil can be used for preparation of bar soaps and that they have stability within the parameters studied
