The extraction of antioxidants from Chlorella vulgaris for cosmetics

Abstract

Chlorella vulgaris is microalgae that contain chlorophyll as antioxidants, which has been widely used as a functional food. Antioxidants from Chlorella vulgaris also have potential as active ingredients in the cosmetics industry. Nowadays, consumers prefer natural cosmetics because they aren’t harmful to the skin. This study aimed to obtain chlorophyll antioxidants from Chlorella vulgaris and applied it to the cosmetics. The extraction process of antioxidants from Chlorella vulgaris was performed by maceration method, with Chlorella vulgaris concentration variable: 0.01; 0.05 and 0.1% in water as solvent. The antioxidant extracts powdered by spray drying method, with addition of 100 g/L maltodextrin. The observation was conducted on the characteristics of water content, ash content, carbohydrate content, protein content, antioxidant activity, and powder morphology. The extracts powder applied to cosmetics in the form of creams and lotions, then characterized for the antioxidant activity and microbial content. The best antioxidant capacity of extract powder was obtained on Chlorella vulgaris concentration 0.1%, which was 11.83 mg Vit C per 100 g sample. The results of antioxidant capacity in cosmetics as cream and lotion were 4.95 mg Vit. C per 100 g sample (IC50 719.75 mg/ml) and 4.73 mg Vit. C per 100 g sample (IC50 660 mg/ml), respectively. Both of cream and lotion weren’t shown any microbial contamination. Based on this study, Chlorella vulgaris with its antioxidant capacity can be developed as active ingredients for various kinds of cosmetics.

Influence of magnesium concentrations on the biomass and biochemical variations in the freshwater algae, Chlorella vulgaris

“…Growth of Chlorella vulgaris under alkaline conditions increases the lipid and carbohydrate content, as cells accumulate oils as a defense mechanism against stress conditions [ 57 ]. The culture that removed Mg 2+ could increase the lipid content of Chlorella protothecoides UTEX 250 from 4.4% to 9.5%, and a heavy metal ion was helpful for the increase of some of the microalgae's lipid content [ 58 ].…”

Evaluation of antioxidant potential of pigments extracted from Bacillus spp. and Halomonas spp. isolated from mangrove rhizosphere

“…On the other hand, synthetic antioxidants are not preferable for long-term consumption because of their reported side effects (Phaniendra et al, 2015 ). Therefore, recent studies on antioxidants have focused on screening different natural compounds and evaluating their pharmaceutical activities (Agustina et al, 2021 ; Foong et al, 2021 ; Sakihama and Yamasaki, 2021 ).…”
