Cyclodextrin-coated denim fabrics as novel carriers for ingredient deliveries to the skin

• Fixation of MCT-β-CD for preparing host–guest system on denim fabric was studied.
• Efficiency of each fixation methods was evaluated by FTIR-ATR, CHNS, and SEM analysis.
• Effects of MCT-β-CD fixation methods on the substrate performance were investigated.
• Air permeability, moisture absorption, fastness and hand properties were investigated.
• Priority of each method for grafting of MCT-β-CD was established.

Garments with coverage of a large part of the body generate an exceptional opportunity for transferring active ingredient to the skin. A fabric finished with β-cyclodextrin derivatives can play a role as a host for a next active substance as a guest. In this paper, different methods for permanent fixation of Monochlorotriazinyl-β-Cyclodextrin (MCT)-β-CD, on inner side of a denim fabric were investigated as a carrier with the purpose of substance formation inclusion complex with (MCT)-CD hydrophobic cavity. In order to fix MCT-CD on the fabric surface, two methods were investigated: (1) simultaneously or one step- and (2) pre- or two step-carbonating with sodium carbonate. Varying chemical and physical analyses such as gravimetrical and elemental analysis, FTIR spectroscopy, SEM images and fastness properties measurements, were studied to evaluate the quality of the host molecule stabilization on the textiles substrates and distinction of better application method.
