The potential of chitosan from comb-pen (Atrina pectinata) shell waste on the characteristics of hand body cream

The comb-pen shell is one of the sources of chitosan, which is a natural substance derived from chitin and could found in Indonesia. In the non-food sector, chitosan can used as antibacterial, antioxidant, and thickening on hand body cream ingredients. This study aimed to determine the effect of the addition chitosan from comb-pen shell waste to the characteristics of hand body cream. The parameters, including pH, TPC, and Homogeneity were tested on the first day and after fourteen-day storage at room temperature. The pH test results ranges from 7.8 to 8.0. The TPC test result is <10 CFU/25 g in every sample on both test. The hand body cream homogeneity has the same homogeneity level between the control and the treatment samples. The viscosity results were obtained from literature studies regarding the manufacture of hand body cream using chitosan from small crab (Portunus pelagicus) shells. The characteristics of hand body cream has a good result on every parameter tests shown that are fulfilled the standard of Indonesia Nasional Standards (SNI). The addition of chitosan from comb-pen shell (Atrina pectinata) waste affects the characteristics of hand body cream.
