Abstract:
This study was aimed to apply betel nut (Areca Catechu Linn.) extract in blemish balm (BB) cushion. Formulation of W/Si+O emulsion base was performed. The base containing 1% w/w cyclopentasiloxane (and) PEG/PPG-20/15 dimethicone and 2% w/w PEG10 dimethicone made product more stable without phase separation. Furthermore, 1% w/w dimethicone/vinyl dimethicone crosspolymer (and) silica and 6% w/w Titanium dioxide (nanosilk) can improve stability and coverage effect, respectively. Four types of silicone were added to the formula, including 13% w/w cyclopentasiloxane, 2% w/w dimethicone, 5% w/w phenyl trimethicone and 5% w/w cyclopentasiloxane (and) dimethicone crosspolymer. They were proven to improve texture and sensation of the product. The presence of 1% w/w betel nut extract in BB cushion had no effect on color change without phase separation. The BB cushion added with betel nut extract increased SPF value more than 7.23 folds with PA+++. Moreover, satisfaction study on 30 volunteers revealed that the BB cushion was satisfied which was equal to the commercial product. Therefore, betel nut extract can be applied in BB product that can be further expanded to commercial system.
