Abstract
The aim of this study is to develop cosmetic skin patch with pectin as film former. and to add the value
of lime’s peel disposal. When 10% by weight of pectin and 7% by weight of glycerin as plasticizer were used in
the skin patch preparation, a clear, colorless with best elasticity was achieved with skin well-attachable. The 1 x 1
centimeters of the patch with 0.1931 ± 0.0001 centimeters thickness was 0.0231 ± 0.0001 gram. The absorptive
activity was 119.02 ± 5.47%, elasticity was 12.4327±0.0213 N/mm. Little visible changes after the accelerated
stability tests were yellowish color, texture of dry and less elastic, weight loss, and less thickness. The cost of one
skin patch with 10 x 20 centimeters and 0.1 centimeters thick was calculated. It was 1.95 baths each, which was
competitively to commercial ones.
