Możliwości wykorzystania w kosmetologii wybranych olejów roślinnych jako źródła karotenoidów

Abstract

Introduction. Plant oils, due to the content of polyunsaturated fatty acids, which have a positive effect on the condition of the skin, are widely used in cosmetology. Some of them are also used as a rich source of carotenoids, plant dyes, which enjoy unmatched interest of cosmetics manufacturers because of their properties (color, physiological activity). Aim. The aim of the study was to compare the total carotenoid content, including β-carotene, in selected plant oils applied in cosmetology. Material and methods. The carotenoid content in sea buckthorn (Hippophaë rhamnoides L.), carrot (Daucus carota L.), marigold (Calendula officinalis L.) and pumpkin (Cucurbita pepo L.) was determined by UV/VIS spectrophotometry and HPLC methods. Results. The tested plant oils have a different content of plant dyes. In terms of total carotenoid content, including β-carotene, they can be arranged as follows: sea buckthorn oil > carrot oil > marigold oil > pumpkin seed oil. Conclusions. The results of this study show that the tested plant oils, especially sea buckthorn oil, can be used in cosmetic formulations as a source of carotenoids, including β-carotene.
