REVIEW: METHODS FOR THE REUSE OF COFFEE GROUND FOR OIL EXTRACTION TO OBTAIN SUSTAINABLE RAW MATERIAL FOR COSMETICS

Abstract

The coffee industry generates different residues, one of them is the coffee grounds, which has biological activities which have shown expressive anti-radical, antioxidant, antitumor, anti-inflammatory and anti-allergic activities, since the extracted oil has excellent concentrations of antioxidants, anti-inflammatory, immunomodulators and fatty acids. This composition makes the coffee grounds an excellent raw material for obtaining cosmetic and pharmaceutical products. In recent years, the term sustainability is on an increasing rise, therefore, the concerns in the cosmetics industry about the impacts generated by its products have been intensified, creating careful selections of the raw materials used. This review was carried out with the aid of the scientific literature contained in three databases together with other sources of information. Twenty-eight articles correlated with the theme of the review were selected and analyzed using two software that enabled the identification of the characteristics and benefits of coffee oil and the main methods for extracting oil from the coffee grounds used as a source of reuse and treatment of solid waste, thus, it was possible to map the perspectives addressed in this scenario in recent years.
