Abstract:
The aim of this study was to develop hair wax containing black glutinous rice extract for styling and covering gray hair simultaneously. Extraction with 95% ethanol containing 0.2 M HCl provided the highest yield of the extract of 2.67±0.15 % w/w and the highest anthocyanin content of 90.54 ± 1.46 mg cyaniding-3- glucoside equivalent/ g extract. After heating-cooling test for 4 cycles, the anthocyanin content was present its high stability as 99% residual but total color change (∆E) appeared to be 3.30. Development of hair styling wax with 1% and 2% extract showed high stability of the products with minor changes of their color, viscosity and pH. The wax containing 2% extract efficiently covered gray color of hair tresses and its efficiency was still present after leaving the hair samples at room temperature and under neon light conditions. However, its gray hair covering capacity was lost when rinsing the hair with tapping water for 1 min. For exposure to sun light condition, even the product could retain dark color to gray hair tress, the hair sample become drier after testing. Satisfaction test of the hair styling and gray covering wax on volunteer revealed that 75% of the volunteers satisfied in very good level for all properties tests of the product.
