In this study, Chenopodium pallidicaule (Cañihua) oilseed was investigated to determine the composition, and main physico-chemical properties to establish its potential cosmetic applications. The results were compared with well-known vegetable oils. The extraction yield was 2.14±0.01 g of extracted oil/100 g of dry-weight seeds. Unsaturated fatty acids were the most abundant in Cañihua oil. The major unsaturated fatty acid was linoleic acid (42.1%), followed by oleic acid (24.7%) and linolenic acid (3.0%). The specific gravity was 0.897±0.01 (20°C), the average acid value was 0.48±0.14 mg / KOH, the peroxide value was 5.0±1.34 mEqO2/kg, the iodine value was 175.3±18.63 g I2/100 g, and the saponification number was 190.0±0.01 mg KOH / g oil. Other properties for use in cosmetic formulations like surface tension, viscosity, spreadability, and pour and cloud points were similar to those of other vegetable oils used in these formulations. A stable cosmetic emulsion was formulated using Cañihua oil (5%). All results demonstrated the potential of Cañihua oil as an ingredient for cosmetic emulsions for skin treatment.
