Abstract:Utilization bractea B. spectabilis Willd in a cream preparation containing flavonoids,
alkaloids, saponins, terpenoids and quinones functions as a sunscreen. The addition
of extracts affects the stability of the cream preparation due to the difference in
polarity with the cream base so a stability test is required. Physical stability testing is
required to ensure the cream preparation continues to meet the requirements during
the storage period. This research aims to determine the physical stability of the
method thermal cycle on extract cream bractea B. spectabilis Willd related
organoleptics, homogeneity, pH, stickiness, spreadability, and viscosity in room
temperature storage for 6 cycles and compared the physical stability of cream with
and without extract. Extraction by maceration using 70% ethanol, followed by testing
the flavonoid extract and making cream. The test results were analyzed using SPSS
23.0 with the Repeated ANOVA test. Data are presented in the form of mean SD
with a confidence level of 95%. Results of physical stability test of ethanol extract
cream preparations bractea B. spectabilis Willd (0.5; 1.0 and 1.5%) by method
thermal cycle including Organoleptic, homogeneity, pH, viscosity, stickiness,
spreadability, cream type remains stable with O/W cream type. |
