Produção de creme hidratante a partir de óleo essencial extraído do amendoim Arachis Hypogaea L.

Abstract

The process of extracting seed oils through the use of solvents is widely used in the industrial environment due to its simplicity and high efficiency. The oils obtained from natural origin can have the most diverse purposes in numerous industrial segments, being the cosmetic industry one of them, as substituents of synthetic compounds. This work aimed to elaborate a hydrant cream using peanut oil of two different varieties, white and red peanuts. The crude peanut oils were obtained by continuous extraction (soxhlet) using hexane as the solvent. After extraction, the oils presented good results with appropriate physicochemical data for oils (acidity index between 1.52 and 2.06 mL NaOH / g oil, density in the range of 0.86 gcm-3 and 0, 87 gcm-3, refractive indexes between 1.470 and 1.468) at a temperature of 20 ° C. These oils were then used to formulate a moisturizing cream, replacing the natural extract in the proposed formulation, and in the final product obtained it was not possible to identify color interference and aromas from the substitution of materials. The cream exhibited homogeneity and viscosity visually comparable to commercial moisturizing products, in addition to forming a stable emulsion with good dispersion of dyes and essence when they were added.
