The aims of the research were to investigate the effect among CMC, propylene glycol, and the interaction between CMC and propylene glycol on the gel physical properties and stability of green tea-polyphenol-dry extract sunscreen gel formulas. This research was a pure experimental study based on factorial design application. Four formulas were investigated, i.e. (1): CMC and propylene glycol both in low level, 9a): CMC in high level and propylene glycol in low level, (b): CMC in low level and propylene glycol in high level, (ab): CMC and propylene glycol both in high level. They were evaluated for their physical properties parameter; i.e. spreadability, viscosity, and viscosity shift of gel over 1 month storage. Statistic analysis used was Yate's treatment with 95% level of confidence. The result showed that CMC was dominant in determining gel spreadability, gel viscosity, and viscosity shift of green tea-polyphenol-dry extract sunscreen gel.
