“…Additionally, deterioration of fabrics in terms of color degradation, loss of elasticity and tensile strength, and interference with the dyeing and printing processes can occur . Hence, it is crucial to combat these undesired effects through imparting of effective antimicrobial additives to textiles. , …”

Fragrant and antimicrobial properties were conferred to cotton fabrics following microencapsulation using green materials. Limonene and vanillin microcapsules were produced by complex coacervation using chitosan/gum Arabic as shell materials and tannic acid as hardening agent. The effect of two emulsifiers; Span 85 and polyglycerol polyricinoleate (PGPR), on the encapsulation efficiency (EE%), microcapsule's size and morphology, and cumulative release profiles was studied. The mean diameter of the produced microcapsules ranged between 10.4 and 39.0 μm, whereas EE% was found to be between 90.4% and 100%. The use of Span 85 resulted in mononuclear morphology while PGPR gave rise to polynuclear structures, regardless of the core material (vanillin or limonene). The obtained microcapsules demonstrated a sustained release pattern; namely the total cumulative release of the active agents after 7 days at 37 ± 1°C was 75%, 52% and 19.4% for the polynuclear limonene microcapsules, the mononuclear limonene microcapsules and the polynuclear vanillin microcapsules, respectively. Grafting of the produced microcapsules onto cotton fabrics through an esterification reaction using citric acid as a nontoxic cross-linker followed by thermofixation and curing, was confirmed by SEM and FTIR spectroscopy. Standard antibacterial assays conducted on both microcapsules alone and impregnated onto the fabrics indicated a sustained antibacterial activity.

“…52 Improving on these results with the aim to afford an antimicrobial and fragrant finishing, Sundrarajan in India recently used biodegradable gum acacia to encapsulate limonene via coacervation. 53 The resulting cotton fabrics are capable of retaining antibacterial properties even after 5 washing cycles due to covalent bonding of terpene to the gum acacia microcapsule through the citric acid cross linker.…”

Limonene: a versatile chemical of the bioeconomy

et al. 2014

(+)-Limonene is a renewable chemical with numerous and growing applications. Its traditional uses such as flavor, fragrance and green solvent are rapidly expanding to include its utilization as a platform chemical, extraction solvent for natural products and an active agent for functionalized products. We anticipate that the expansion in uses for limonene will translate into increasing production and use of this relevant natural product, especially for advanced applications.

“…Limonene has been used as a common dietary supplement, as a botanical insecticide, in tissue preparation for histology and as a solvent for cleaning, among other applications [ 17 , 19 , 20 , 21 ]. Its bioactivity is also quite remarkable, possessing both significant anti-carcinogenic and antimicrobial activity, which are mainly attributed to its metabolites, such as perillic acid (PA) [ 22 , 23 , 24 , 25 , 26 ]. In this sense, it has been reported that limonene works as a sort of pro-drug since the therapeutic effect of its metabolites has been shown to be far greater [ 18 , 25 , 27 ].…”

Optimal Design of THEDES Based on Perillyl Alcohol and Ibuprofen

Therapeutic deep eutectic systems (THEDES) have dramatically expanded their popularity in the pharmaceutical field due to their ability to increase active pharmaceutical ingredients (APIs) bioavailability. However, their biological performance has not yet been carefully scrutinized. Herein, THEDES based on the binary mixture of perillyl alcohol (POH) and ibuprofen (IBU) were prepared using different molar ratios. Our comprehensive strategy includes the characterization of their thermal and structural behavior to identify the molar ratios that successfully form deep eutectic systems. The in vitro solubility of the different systems prepared has demonstrated that, unlike other reported examples, the presence of the terpene did not affect the solubility of the anti-inflammatory agent in a physiological simulated media. The biological performance of the systems was studied in terms of their antimicrobial activity against a wide panel of microorganisms. The examined THEDES showed relevant antimicrobial activity against all tested microbial strains, with the exception of P. aeruginosa. A synergistic effect from the combination of POH and IBU as a eutectic system was verified. Furthermore, the cytotoxic profile of these eutectic systems towards colorectal cancer (CRC) in vitro cell models was also evaluated. The results provide the indication that the cell viability varies in a dose-dependent manner, with a selective THEDES action towards CRC cells. With tunable bioactivities in a ratio-dependent manner, THEDES enhanced the antimicrobial and anticancer properties, representing a possible alternative to conventional therapies. Therefore, this study provides foreseeable indications about the utility of THEDES based on POH and IBU as strong candidates for novel active pharmaceutical systems.
