Abstract
By-product from reeling eri cocoons is degumming waste water. Therefore, the objective of this research is to exploit the extracted protein from eri waste water as an ingredient of indigenous knowledge cosmetics for value added creation. In this study, liquid soap; shampoo and lotion were prepared using protein from degumming water as ingredient with different formulae (treatments). For liquid soap, 3 formulae were tested, Formula 1 (control); Formula 2 (plus protein from degumming water at the end concentration of 0.01%) and Formula 3 (plus protein from degumming water at the end concentration of 0.05%). The result showed that the soap of Formula 2 was clear brown color. Formula 3 had clear brown but slightly darker color than Formula 2 whereas Formula 1 was clear in color. The soap were evaluated for preference by users. The result revealed that there was no irritation and feel better (66.67% of the users) after application. Fifty percent of users preferred the soap Formula 2 with rating of the most preference score and feel ungreased, soft skin, much moistening feeling and easy to clean. Whereas, shampoo was developed according to 3 formulae, Formula 1 (control), Formula 2 (plus protein from degumming water at the end concentration of 0.01%) and Formula 3 (plus protein from degumming water at the end concentration of 0.05%). The shampoo Formula 3 exhibited
clear brown color and slightly darker than Formula 2 while Formula 1 had no color. All Formulae were not irritated and feel better after use by 100% preference of the evaluators. The users preferred shampoo Formula
3 than others in the most preference score with following information: good out-look hair, lustrous, weighing, soft hair and good spring. In making lotions, 10 formulae (treatments) were developed. Most users provided
information, good feeling, moisture and soft skin after use of the lotions. They (33.33%) preferred in the level of most preference score for Formula 1(B) with 0.05% protein and Formula 2(A) with 0.01% protein according to
soft, moisture, smooth, slightly fragrant, and ungreased. In conclusion, all of these tested eri cosmetics are accepted better than commercial products based on protein concentration and preparation procedure. Moreover, degumming waste water of Thai mulberry silkworm varieties were also tested. This research contributes the potential of eri silk protein from degumming waste water, which can be applied as an ingredient in cosmetics towards the farmer’s income generating.
