Optimization of quality, safety and health aspects in personal care product preservative design

Abstract

Personal care products (PCPs) are structured products that are constituted by numerous chemicals ingredients. However, there are several hazardous ingredients in PCPs that may cause exposure to consumers and lead to adverse health impacts. The main contribution of this study is the development of a comprehensive framework for the PCP ingredient design that integrates the safety and health aspects as well as performance aspects simultaneously into computer-aided molecular design (CAMD). Mathematical optimization programming is utilized in this study to generate a list of high quality, poses good safety and health-performance PCP preservative candidates. Furthermore, an index-based safety and health effect assessment is presented in this study. In addition, the exposure assessment of the selected molecule is performed by applying Margin of Exposure. A case study on PCP preservative design is presented. Laboratory experiment is carried out to verify the feasibility of the addition of safer and healthier preservative into the eye cream formulation.
