Optimization of Polyvinyl Alcohol (PVA) and Glycerin in Kolang Kaling Peel-Off Gel Mask Formula (Arenga pinnata.)

Aging is caused by free radicals, one of which ultraviolet light can form ROS. Galactomannan compounds have the potential as antioxidants that counteract radicals. Kolang kaling contains many galactomannan compounds. processed into a peel-off gel mask, where PVA and glycerin are essential ingredients. polymer film layer, but if layer not balanced, used humectant. The results FTIR analysis showed functional groups were D-galactopyranose D-mannopyranose, characteristic galactomannan. IC50 kolang powder 23.8720 ppm, powerful antioxidant. interaction increased drying time, viscosity, antioxidant activity, decreased dispersion, adhesion, pH. optimal formula obtained was 14.47% 15.73% glycerin. One Sample T-Test validity test found equations each valid.
