This study examined the feasibility of using β-cyclodextrins (βCDs), which are derived from starch, as agents to stabilize volatile and leachable biocides for the protection of wood and wood composites. The encapsulation of volatile natural antimicrobial compounds, such as allyl isothiocyanate (AITC) and essential oils (EOs), in βCDs was qualitatively confirmed by Attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) method and the maximum inclusion yield was quantitatively estimated by ultraviolet-visible spectrophotometry (UV/VIS) while the partial fixation of leachable borates with βCD was confirmed by ATR-FTIR and nuclear magnetic resonance (NMR) techniques. The efficacy of the βCD complexes as wood preservatives of southern yellow pine and randomly Oriented Strand Board (OSB) was examined in soil block tests (AWPA Standard E10-16 and E22-16). The results indicate that (A) βCDs suppress the premature leaching of otherwise volatile natural compounds and suggest a novel approach to the application of volatile or water-immiscible natural preservatives for wood and wood composites protection; (B) βCD can be used as an agent for partial fixation of boric acid to form boric acid esters. However, the borate esters are susceptible to leach out after AWPA Standard E11-16 test and not suitable for protection against Gloeophyllum trabeum and Postia placenta in outdoor conditions.
