Fabric detergents for body-odor reduction

Abstract

This research targets to prepare detergents containing β-cyclodextrin and to use them for fabric laundry in order to improve the body-odor removability of detergents. Three local detergents consisting of two powder detergents (diluted and concentrated) and one liquid detergent (concentrated) were mixed well with various amounts of cyclodextrin powder and they were used for laundering microfiber polyester fabric containing body-odor, compared with using detergents without cyclodextrin. Results from electronic nose analysis indicated that detergents with cyclodextrin provided better body-odor removability than detergents without cyclodextrin. Lower level of body-odor was found on fabric and lower washing cycle was needed when laundering fabric with detergents containing cyclodextrin. Some fabrics showed odorless with only one washing cycle using these high performance detergents. FTIR and SEM analyses indicated that there were cyclodextrin particles left on fabric after washing with detergents containing high content of cyclodextrin.
