Hair loss is a problem that can interfere with performance. Green tea extract with a content of 5% is proven to stimulate hair growth (Sumakdjaja, et al., 2008). Active substance in green tea (Camellia sinensis L) is efficacious as a hair fertilizer is catechin compound and its derivatives.
Green tea flavonoid compounds composed of epicatechin (EC), epicatechin error (ECG) and epigallocatechin gallate (EGCG). It also contained gallic acid, galokatekin error (GCG), galokatekin (GC), catechin error (CG), catechin (C), vitamin B and vitamin C (Agus, 2007) that can strengthen the hair roots, prevents loss of hair roots, inhibit free radicals, neutralize toxins, and protects the scalp from infection. Formula cosmetic and food preparations contain active green tea has seized public attention. Active hair fertilizer made from green tea extract gel has not been found among the people. Based on this phenomenon, this study aims to develop hair fertilizer gel formula with active extracts of green tea.
The research was conducted by creating four formulas, the formula I (1% Carbopol, TEA 0.3%, 1% glycerol), formula II (CMC Na 3%, 1% glycerol), formula III (72% PEG 400, PEG 4000 8%, 1% glycerol) and the formula IV (0.75% Carbopol, TEA 2%, 12% PEG 400, glycerin 1%). Each formula contains green tea extract with a content of 5%, 0.1% nipagin preservative, sodium metabisulfite and 0.1%, preparations are made of 100 grams. The fourth gel was then tested the quality of preparations include organoleptis test, homogeneity test, pH test, test dispersive power, adhesion test, a test of power protection, primary irritation test, test aseptabilitas, hair fertilizer and test activities.
The study found that the most optimal gel formula is the formula I which comprises 1% Carbopol, TEA 0.3%, and glycerin 1%. Formula I shows good consistency of gel, hair fertilizer has the highest activity, does not irritate the skin, as well as having good aseptabilitas.
