FORMULATION OF POWDER (FACE POWDER) OF MANGOSTEEN PERICARP (Garcinia mangostana L) ETHANOL EXTRACT AS NATURAL COSMETIC COLORANT AND STUDY ON ITS STABILITY AND IRRITATION TEST

ABSTRACT

Mangosteen (Garcinia mangostana) is a tropical fruit. One of the mangosteen fruit parts that can be used is its pericarp. Pericarp of mangosteen (Garcinia mangostana L.) produces red to purple due to the presence of anthocyanin pigment. Anthocyanin has many benefits, one of them is as a natural colorant. The aim of this study was to replace the synthetic colorant in face powder to mangosteen pericarp extract as the natural colorant.

This study used laboratory experimental method with qualitative observation. Powder formulation consists of several components such as talc, zn stearate, bolus alba, liquid paraffin, and mangosteen pericarp extract as natural colorant with concentrations of 40.5%, 45.5%, and 50.5%. Extract of mangosteen pericarp was obtained by maceration process with 95% ethanol. The tests for the extract include organoleptic evaluation and color stability. Evaluation of powder was done with organoleptic evaluation and stability test of the powder during 4 weeks of storage. To ensure the safety, preparations were examined with irritation test in human and pH test.

Formulation of powder using mangosteen pericarp extract as natural colorant showed that the powder preparation attached to the skin with pH of 4.5 – 6.5. The best preparation was formula II with mangosteen pericarp extract concentration of 45.5%, it showed no irritation in human and was stable in storage temperature of 40°C.

Keywords: mangosteen pericarp (Garcinia mangostana L.), powder (face powder), stability test, and irritation test.
