Characteristics of seaweed porridge Sargassum sp. and Eucheuma cottonii as raw materials for lip balm

A lip balm is needed to overcome skin problems such as dry lips, cracked, dark, and wrinkled and premature aging of the lips. A Lip balm that contains antioxidants and bioactive compound is needed to inhibit free radical activity and overcome problems in the lips. Seaweed is a natural material that is quite abundant and has a variety of bioactive compounds, including seaweed Sargassum sp. and E.cottonii. This study aimed to characterize and obtain the best formulas of seaweed Sargassum sp. and E. cottonii combination in producing lip balm preparations, as well as obtaining the best lip balm formulations perceived from antioxidant analysis, pH, and loss on drying. This research consists of two stages of research. First stage research was to characterize and prepare the seaweed raw material, characterize and production of seaweed Sargassum sp. and Eucheuma cottonii porridge. Second stage research was the preparation of lip balm preparations. The results showed that the best ratio of seaweed Sargassum sp. and E. cottonii was found on 1: 1 ratio with IC₅₀ antioxidant value of 576.41 ppm, pH 5.39, and Loss on drying 3.52%. The pH value of the lip balm in corresponds to the SNI and pH of the normal human skin balance. Sargassum sp. and E. cottonii seaweed contain phytochemical compounds such as steroids, triterpenoids, flavonoids, and saponins. The content of phytochemical compounds indicates that Sargassum sp. and E. cottonii potential can be used as raw material in making lip balm.
