Microemulsion Formulation and Detergency of Bergamot Multi-Purpose Cleaner Following Thai Community Product Standard

Abstract

The objective of this research is to formulate the environmentally friendly multi-purpose microemulsion-based cleaner following the Thai community product standard. The optimum formulation was selected based on the microemulsion Winsor type III for the removal of rice bran oil from the white fabric (cotton/ polyester (95:5) blend). The results showed that the maximum rice bran oil detergency (98.8%) was achieved using 200 ml of washing solution containing the 10% vol. Dehydol® LS3TH and 10% wt. NaCl at the washing cycle of 40 min. Additionally, the test properties of the multi-purpose cleaner including pH, the quantity of surfactant and microorganisms were achieved the quality standard of the Thai Community Product. From the characteristic study of the rinse solution, it was found that the pH, phosphate and COD values were in the normal range of the household wastewater characteristics. Thus, this study could be concluded that the microemulsion-based multi-purpose cleaner has better detergency efficiency than the local products, reaches the Thai Community Product  standard.
