Biofunctional Textiles with Inclusion Complexes of Citronella Oil with \(\beta\)-Cyclodextrin

Abstract

Integrated medication delivery systems in biofunctional textiles can aid in the battle against vector-borne illnesses. Instead of using DEET (N,N-diethyl-m-methylbenzamide), which has drawbacks such toxic responses and skin damage, you can utilize repellents made from plants and oils. However, according to some experts, there are instances where essential oils are useless because of issues with uncontrolled release. This study looked at how citronella oil (OC) complexed with -cyclodextrin (CD) controlled the behavior of cotton (COT) and polyester (PES) textiles. The findings show that coating cotton and polyester with -cyclodextrin complexes enables control over the essential oil's release mechanism from the fabric. Optical microscopy, SEM, and FTIR were used to evaluate the complexes created; UV spectroscopy was used to determine the yield of complex formation; and controlled release was carried out in vitro. Oil complexation with CD had a yield of 63.79%, and it was found that when applied to textiles, the release, which had previously been measured in seconds, had changed to hours. The findings indicate that complexes, when modified with chemical crosslinking agents, appear to offer a potential basis for immobilizing oils and regulating their release.
