Diseño de un rubor cremoso fitocosmético a partir del extracto de cáñamo (cannabis sativa)

Abstract

In recent years, interest in natural-origin cosmetic products has grown significantly, driven by increasing environmental awareness and consumer demand for cleaner, more sustainable, and transparent formulations. In this context, hemp (Cannabis sativa) emerges as a promising alternative due to its anti-inflammatory, antioxidant properties and its potential as an eco-friendly crop. Its incorporation into cosmetic formulations opens new possibilities for developing more environmentally responsible and dermatologically safe products. This study aimed to design a phyto-cosmetic creamy blush using hemp extract, applying a D-optimal mixture design. The extract was characterized by pH, viscosity, and relative density—parameters suitable for inclusion in semisolid preparations. The final product exhibited a pH of 4.05, within the safe range for facial cosmetics, and met microbiological standards with no presence of pathogenic microorganisms. Additionally, the product's stability was evaluated through thermal cycling tests, showing resistance to temperature fluctuations (40 °C and 4 °C) without significant changes in pH or spreadability, indicating good physical stability. A sensory evaluation was also conducted through a survey of 25 participants, who assessed attributes such as color, odor, texture, durability, and potential dermatological reactions (burning, itching, redness, or greasiness), yielding highly favorable results. The findings support the use of hemp extract as a functional ingredient in natural cosmetics and demonstrate that the developed blush possesses suitable characteristics of stability, safety, and user acceptance..
