Stability of yellow, orange, and green extracted from vegetables on lip balm

The use of natural lip balm started to get the attention of people when they realized the harmful effects of synthetic colourant on lip balm towards human health. This research interest focused on to produce natural lip balm based on extracted natural colour from the carrot, Pandan leaf, and turmeric and to compare and study on the stability of natural lip balm with the existing synthetic lip balm sold in market. The stability of the natural lip balm being observed by taking the reading from Chromameter which yield values of L*, a*, and b*. The most stable pigment was Carotene with values in a range of 82 to 85 for L*, -2.5 to -3.5 for a*, and 9.3 to 10.7 for b*. Slightly stable pigment was Chlorophyll with values in a range of 70 to 76 for L*, -14 to -15 for a*, and 29 to 31 for b*. Least stable pigment was Curcumin which having values varies in range of 55 to 60 for L*, 5 to 10 for a*, and 15 to 25 for b*. In average, melting and breaking point of formulated natural lip balm are 36.5°C and 0.113 respectively. Low in values is due to high amount of Shea Butter use for the formulation. Melting point of synthetic lip balm is doubled from natural lip balm and this proven that the melting point relates to the amount of wax use since 2 types of wax use as ingredients of synthetic lip balm. Solubility test shows lipid characterization since lip balm was only totally dissolved in chloroform and failed to dissolve in both water and ethanol solvent. The highest peak wavelength absorbed was in a range of 2843 cm¯¹ to 2859 cm¯¹ for all 3 natural lip balms and this functional group belongs to Beeswax which the base ingredient for the formulation. In conclusion, the experiment was done successfully but the result do not reproducible due to the insensitivity of chromameter during colour measure.
