Processo de extração artesanal do óleo do abacate para aplicação em produtos cosméticos

Abstract

The growing interest in natural-origin cosmetic products has driven the search for plant-based raw materials that exhibit functional properties and can be obtained through sustainable processes. In this context, avocado oil stands out due to its rich composition of bioactive compounds and its potential application in moisturizing cosmetic formulations. The present study aimed to evaluate the production of avocado oil through an artisanal extraction process, without the use of chemical reagents or industrial steps, as well as to assess its feasibility for application in the development of a moisturizing cosmetic cream. The extraction was performed using the fruit pulp, prioritizing the preservation of the oil’s natural characteristics and the adoption of a simple, sustainable, and accessible method. After extraction, the oil was subjected to quality analyses over time, considering parameters related to its stability, safety, and suitability for cosmetic use. Subsequently, the oil was incorporated at different concentrations into moisturizing cream formulations, which were evaluated for stability during storage, considering physicochemical and sensory characteristics, as well as compatibility with the packaging. The main parameters analyzed for the extracted oil were peroxide value, acid value, and moisture content. For the cosmetic formulations, a stability test was performed, evaluating appearance, color, odor, and pH. The analyses of the aforementioned parameters were performed in triplicate. The oil presented a peroxide value of 0 meq O₂ kg⁻¹, an average acid value of 3.46 mg KOH g⁻¹, and an average moisture content of 65.71%. For the moisturizing cream formulations, changes in appearance were observed during the stability period in the formulation containing 15% avocado oil. The results indicated that the oil obtained through artisanal extraction exhibited characteristics compatible with its application in cosmetic formulations, while the developed creams maintained stability throughout the evaluation period. It was concluded that the use of avocado oil obtained through artisanal methods represents a viable and sustainable alternative for the development of cosmetic products, provided that adequate quality and stability controls are performed to ensure the safety, efficacy, and acceptability of the final product.
