Background and Aim: Marine seaweeds are a valuable source of bioactive ingeredients with the possibility of different effects in cosmeceutical industries such as skin health products. One of the main characteristics of the skin is moisture which plays an important role in maintaining metabolism, enzymatic activity, mechanical properties, appearance and protective barrier. The objective of the present study was to formulate the water extract of brown algae Sargassum tenerrimum with antioxidant and antibacterial properties as a moisturizing cream to evaluate physicochemical stability and microbial growth.
Methods: Algae were collected from the Persian Gulf intertidal zone and was washed with seawater, then transferd to Seafood Processing Laboratory in Gorgan University of Agricultural Sciences and Natural Resources for extraction process, after that formulation of 1% moisturizing cream was made at Center for Research and Training in Skin Diseases and LeprosyTehran University of Medical Scinces. Statistical analysis of antibacterial properties of water extract was performed by SPSS software version 22 and one way ANONA was used to analyse the data. The comparison between the means were investigated by Duncan’s test used for measuring significant differences at 5 percent level. Finally, the charts were created by using Excel software. The results of the study were reported as mean ± standard deviation.
Results: According to the results, the prepared 1% cream was completely stable and homogeneous in room temperature and oven for 6 months and successfully passed microbial tests.
Conclusion: In view of the above mentioned, the manufactured cream efficacy was well done and can be introduce as a skin moisturizing agent.
