Abstract Skin cancer had become one of the most occurring type of cancer all around the world. The needs for alternative additional substance in sunscreen, especially from natural ingredients become important. Seaweed is one of marine natural resource known for its many benefits and widely used in cosmetic industries. The purpose of this research are to determine the photoprotective activity of Eucheuma sp. extract obtained from different type of solvents against ultraviolet radiation and its effect. Eucheuma sp. extracted by maceration using two different solvents (methanol and ethyl acetate). Filtrate obtained from maceration evaporated until the consistency are pasta-shaped and tested using spectrophotometer to determine the SPF, % of Te, and % Tp. The result of spectrophotometer tests evaluated and analyzed to determine which solvent generate the best value of SPF, % of Te, and % of Tp. The result of this this research showed that the highest SPF value are present in ethyl acetate extract (SPF 26.4). The best value of Te and Tp percentage are also present in the ethyl acetate extract with their respective values: 0.88% and 18.64%. The conclusion of this research are Eucheuma sp. extract had a good potential of photoprotective activity.

Polysaccharide isolation of Brown seaweed: Sargassum sp and its photoprotection activity

IOP Conference Series Earth and Environmental Science (2022)

Abstract Sun radiation contains ultraviolet rays consisting of UV-A, UV-B, and UV-C. This ultraviolet light can cause adverse effects on the skin such as the appearance of sunburn (erythema), pigmentation, skin aging, and can also cause skin cancer (melanoma). To reduce the adverse effects on the skin, it is necessary to use sunscreen that protects the skin from exposure to ultraviolet rays. Brown seaweed is one of the natural ingredients that can be used as a natural ingredient for sunscreen. This is because genetically brown seaweed is more often exposed to sunlight so it can synthesize components that can absorb ultraviolet light. Sargassum sp. It is known to have polysaccharide compounds such as alginate and fucoidan which have potential as antioxidants and anti-inflammatory. The purpose of this study was to determine the photoprotective activity of the polysaccharide compounds found in Sargassum sp.
