•Kenaf derivatives and kenaf leaves extract (KLE) showed high antioxidant activity.•The biological, nutritional, and medicinal properties of KSO, KSE and KLE were discussed.•The functional properties of kenaf derivatives importance to pharmaceutical and cosmetic industries.•The technologies for cosmetic formulation development were discussed.•Application of encapsulation technology were found to have beneficial effects on KSO. Kenaf is an alternative fiber crop which is economically viable and ecologically friendly. Kenaf seeds oil, kenaf seeds extract, and kenaf leaves extract were found to have a high content of bioactive compounds to offer antioxidants and medicinal benefits, which could be a potential source in pharmaceutical and cosmetic industries. The application of encapsulation technologies on kenaf derivatives can help to develop new highly effective cosmetic formulations. Different encapsulation technologies were applied on kenaf derivatives to improve the stability and functionality for cosmeceutical application. Technologies such as nanoemulsion, nanostructured lipid carriers, co-extrusion, and spray drying of kenaf seed oil were found to enhance its stability and manage the release of unsaturated oils in cosmetic formulations. Besides, the applications of solid lipid nanocarriers, liposomes, niosomes, and Pickering emulsion were discussed in this paper to show its potential in the encapsulation of kenaf derivatives. This review described the chemical composition and nutritional quality of the kenaf derivatives, and the technologies for cosmetic formulation to enhance our knowledge to use these by-products in the cosmetic application and their advantages. This review has important implications to stimulate its possible utilization and application of kenaf in the cosmetic and pharmaceutical industry.
