Dermocosmetic composition in the form of anhydrous bar with long-lasting hydration properties, restoration of the skin barrier and firming effect based on bioactive ingredients from Amazonian oils and the preparation procedure

Abstract

The present invention relates to an anhydrous, lipid-based solid cosmetic composition comprising a vegetable structuring matrix formed by hydrogenated vegetable glycerides, carnauba wax, and cetyl alcohol, in combination with a multicomponent lipid system including vegetable butters and oils rich in unsaturated fatty acids, as well as silica and an antioxidant, thus maintaining the physicochemical and structural stability of the formulation. The invention also includes a preparation process comprising the controlled formation of a structuring phase, the sequential incorporation of lipid components, and dispersion and solidification steps, resulting in a homogeneous, stable composition resistant to exudation and oxidative degradation under various storage conditions.
