The Utilization of Secang Wood (Caesalpinia sappan L.) Extract Nanoemulsion as Natural Pigment in Lip Cream Preparations

Abstract

Lip cream is a semi-solid lipstick preparation. One of the important ingredients in lipcream preparations is a variety of colorants. Secang wood contains the active compound brazilin which gives it a yellow to purple color which can be used as a natural dye. The conventional lip cream preparations from extracts have low homogeneity and unstable, so it is necessary to increase the stability of the preparation by making a nanoemulsion of secang wood extract which is incorporated into the lip cream preparation. The preparation of 10% secang wood extract nanoemulsion preparation using Tween 80, Virgin Coconut Oil (VCO), and PEG 400 with particle size reduction using a bath sonicator. The concentration of the nanoemulsion preparation was 1% (F3) and 3% (F4) incorporated into the lip cream base and conventional lip cream preparations with the same concentration (F1 and F2). The test results for the size of the 10% secang wood extract nanoemulsion globules were 127.54 ± 0.45 nm (PI: 0.3 ± 0.013). The test results for the F3 and F4 nanoemulsion lipcream preparations had a pink to purple color, pH 6-6.4, spreadability of 5.9-6.8 cm, adhesion of 5.5-6 seconds, the preparation was homogeneous and non-irritating, compared with conventional lip cream preparations F1 and F2 are not homogeneous, the color of the lip cream is paler, and the irritating properties are very mild in both formulas. The conclusion of this research is that secang wood extract can be formulated into a nanoemulsion preparation and incorporated into a lip cream preparation.
