Caryodendron orinocense, Karst., is a tree that grows along the eastern base of the Andes mountains in Venezuela, Ecuador, and Colombia. It is known in Venezuela as 'Nuez de Barinas, nuez or nogal de Barquisimeto' and in other countries as 'inchi', 'taque', 'abay' or 'palo de nuez'. The oil extracted from the 'nuts' (seeds) is edible. The objective of this study was to assess the potential use of the oil extracted from the seeds in cosmetics. The organoleptic characteristics, some physical (viscosity, specific density, extensibility, UV absorbance), and chemical (fatty acid profile, titratable acidity, saponification index, unsaponifiable matter and peroxide value) characteristics, were determined by official methods. The results show a high polyunsaturated fatty acid content (75.13%) and good physical, chemical and toxicological characteristics appropriate for use in cosmetics. It was concluded that the Caryodendron oil should be useful in cosmetic formulations.

Organogels have importance for topical applications because they can be used to deliver drugs in a controlled and prolonged fashion. These are materials consisting of a three-dimensional network of organic molecules dispersed in a solvent. Recent studies have demonstrated that the solvent could be replaced by oils from non-conventional biologic sources.

The Colombian Amazon is a megadiverse region with high potential for commercial use in the pharmaceutical, food, and cosmetic industries, constantly expanding and looking for new alternatives from natural resources; unfortunately, few characterization reports of its profitable non-timber species in Colombia have been conducted. This work aimed to perform a comprehensive analysis of traditionally used species: (Andiroba), (Asai), (Miriti), (Murumuru), (Sacha Inchi), and H.Karst (Cacay).

The Amazon region is rich in genetic resources such as oilseeds which have potentially important local commercial exploitation. Despite its high concentration of bioactive compounds, cacay (Caryodendron orinocense Karst.) oil is poorly investigated and explored.

Nowadays, data concerning the composition of Caryodendron orinocense Karst. (Euphorbiaceae) and Bactris gasipaes Kunth (Arecaceae) seed oils are lacking. In light of this fact, in this paper fatty acids and unsaponifiable fraction composition have been determined using GC-MS, HPLC-DAD (Diode Array Detector), NMR approaches and possible future applications have been preliminary investigated through estimation of antioxidant activity, performed with DPPH test.
