Development of natural acne patch from local materials using quality function deployment technique

Abstract

© The Authors, published by EDP Sciences, 2018. This research aims to develop an acne patch based on local material extracted from silk and mulberry and the implementation of quality tools. The development started with a consumer needs' survey about the acne patch product. Technical requirements were evaluated based on quality function deployment (QFD) technique phase 1 or house of quality (HoQ). The results show that the highest score of consumer requirements is standard, followed by acne pus absorption and acne bacteria inhibition property, respectively. After transforming the consumer requirements into technical requirements, it was found that the highest score of technical requirements is qualified to anti-acne bacteria test, followed by swelling and antioxidant property, respectively. According to QFD result, the product prototype was developed using local materials extract and then evaluated based on consumer satisfaction. The most consumer satisfying feature of the natural acne patch product was the acne treatment and no irritation properties. However, the consumer made suggestion on the strength and stickiness of the product for further improvement.
