Stability of Eleutherine americana (L.) Merr. Extract as Lipstick Colorants as the Change of Temperature, Time, Storage Condition and the Presence of Oxidator
Abstrak: Bawang Tiwai
(Eleutherine americana (L.) Merr bulbus. is a typical plant from Kutai tribes
which commonly used as an anti-bacterial and food coloring. The stability test
is performed to determine the stability of the extract. Stability test was
conducted in two solvents are distilled water and ethanol include the effects
of temperature (25°C, 50°C, 80°C), pH (3, 5, 7), an oxidant for 6 hours,
conditions of storage at room temperature and the temperature of the
refrigerator for 24 hours and storage for 2 weeks. The absorbance of extract in
ethanol and aquadest was decreasing due to the change of temperature, time, the
presence of oxidator but due to pH changes, the absorbance of extract was
increasing. Meanwhile, on the storage condition, showed the highest absorbance
on dark, and room temperature storage compared to other condition.
Key words: Eleutherine
americana (L.) Merr bulbus, stability, color pigment
