Study of Satisfaction towards Herbal Soap Products Containing Extracts from Herbal Extracts Zingiber Cassumunar Roxb. and Thunbergia Laurifolia Lindl.

This research aimed to study the extraction of active compounds from the herbs Plai and Rang Chuet by electric field pulse technique to produce herbal soap.The results showed that the extraction using an electric field pulse technique with an electric field intensity of 6 kV/cm, frequency of 1 Hz, and 300 pulses could extract phenolic compounds from Plai at 0.480.04mg gallic acid/gram sample, which is equivalent to the extraction efficiency of 11.94%.Rang Chuet extracted 0.300.03mg gallic acid/gram sample.The extracts from Plai had the antioxidant activity of 51.33% while Rang Chuet had 20.80%.Compared with the herbal powder, it showed that using an electric field pulse caused the active compounds in Rang Chuet to be lost during extraction.In the test of phenolic compounds and antioxidant activity in the produced herbal soaps, although the analysis results of phenolic compounds were lower, the extracts were selected because of their better appearance.The soaps made from the extracts were clear yellow square blocks without any foreign matter.When tested for physical and chemical properties, it was found that: The pH, hardness, solubility, and foaming were not significantly different from the standard herbal soap.The acceptance test results showed that the developed soap received higher scores in terms of appearance, color, scent, feeling after use, and overall liking than the standard soap, at the very like to most like (8-9 points).This may be because the test period was during the summer, between April and May.This indicates that the developed soap mixed with extracts from Zingiber cassumunar and Thunbergia laurifolia has the potential to be produced for sale.
