Abstract
With the progress of time, demand for healthy and hygienic clothing has gone up tremendously. Fabrics and apparels finished with mosquito repellent finishes belong to one of such highly looked out clothing’s. The present study aims at synthesis, characterization and optimization of β-Cyclodextrin citrate (β-CD CA) followed by its complexion with essential oils of cedarwood, clove, eucalyptus, peppermint, lavender and jasmine for the assessment of repellent efficacy against Anopheles Stephensi by means of arm in cage assays on cotton. Protection time, repellency (%), biting (%) and mortality (%) of inclusion complexes encapsulated with oils were evaluated. Two way ANOVA and post hoc analysis had affirmed the significant effect of essential oil type on bio-assay. Lavender and cedarwood had provided the longest protection times (210 and 160 min respectively); jasmine and peppermint were least effective showing protection times of 20 and 60 min whereas oils of eucalyptus and clove behaved as feeding deterrents. Peppermint and lavender were effective as potential repellents and cedarwood had shown supreme mortality against arthropods. Jasmine was the weakest repellent due to its flower-nectar stimulating upshot for Anopheles stephensi.
Highlights
Due to the increased awareness about health and hygiene, people increasingly demand their clothing to be hygienically afresh and functional as market has been expanded for specialty clothing (Karolia and Mendapara 2005)
The solubility of β-Cyclodextrin citrate (β-CD citric acid (CA)) in water had shown a tremendous increase as compared to native β-CD
Interaction of β-CD CA concentration and curing temperature was most influential on graft yield, tensile strength, yellowness index and durability. 1H-NMR spectral analysis revealed only partial inclusion of essential oils (Eos) into cyclodextrin cavity except JO
Summary
Due to the increased awareness about health and hygiene, people increasingly demand their clothing to be hygienically afresh and functional as market has been expanded for specialty clothing (Karolia and Mendapara 2005). Mosquito repellent textiles are one of the revolutionary ways to advance the textile field by providing immensely needed features of driving away the mosquitoes It protects the human beings from the bite of mosquitoes, and thereby promising safety from the mosquito borne diseases such as malaria, dengue fever, chicken guinea and filarial (Prabha and Vasugi 2012). Khanna and Chakraborty Fash Text (2018) 5:9 natural repellents as essential oils are the upcoming genre of scientific interest due to their non-toxic, non-sticky, non-irritating and eco-friendly nature; essential oil repellents tend to being short-lived in their effectiveness due to their high volatility and requirement of frequent re-application This problem has been tried to be overcome with the controlled release of oils from the textiles using monomolecular inclusion complexes with β-cyclodextrin (β-CD) in native form (Songkro et al 2012), β-CD with crosslinking agents as polycarboxylic acids namely citric acid, BTCA, acrylic acid (Martel et al 2002a, b; Voncina and Marechal 2005; El-Tahlawy et al 2007; Specos et al 2013), MCT β-CD (Hebeish et al 2008; Romi et al 2005; Abdel-Mohdy et al 2008, 2009; Shahba et al 2011; Hebeish et al 2009, 2010) on varied substrates. The aim of present work was the synthesis, characterization, optimization of a novel modified cyclodextrin host (β-CD CA) for inclusion complexation with essential oils and its application on cotton for adjudgement of potential of inclusion complexes against malaria causing arthropods scientifically
