1 | 2024 Article | Physicochemical And Morphological Characterisation Studies Of Fabrics Treated With Lavender Essential Oil-Based Nanoemulsion Azlan bin Kamari, Norjan binti Yusof Lavender essential oil is a concentrated plant extract obtained through steam distillation. It is well known for its properties as a good anxiety and stress reliever, for wound healing, for insect repellency and as an insomnia fighter. However, there are many volatile chemical compounds in the essential oil. Hence, formulating a lavender essential oil nanoemulsion is a potential solution to prolong those exclusive applications of the essential oil. Lavender essential oil-based nanoemulsion (LEONE) was prepared with tragacanth gum and Triton X-100 by a combined method of ultrasonic and high-speed homogenisation. This study focused on the physicochemical and morphological characterisation effects of fabrics treated with LEONE. Morphological and physicochemical evaluation of nanoemulsions were conducted by optical microscopy (OM), high resolution transmission electron microscopy (HR-TEM) and Fourier transform infrared (FTIR) spectroscopy. Ultraviolet-visible (UV-Vis) spectroscopy was util..... 62 hits |
2 | 2024 Article | Lemongrass essential oil nanoemulsion formulations based on tragacanth gum and guar gum as durable anti-mosquito fabric finishing agents Azlan bin Kamari, Norjan binti Yusof Mosquito-repellent textiles are classified as protective textiles designed to mitigate the presence of mosquito species recognised as vectors for diseases such as malaria and dengue fever. This study aimed to explore the feasibility of employing a nanoemulsion system containing lemongrass essential oil encapsulated with biopolymers, specifically tragacanth gum and cationic guar gum, as finishing materials on cotton and polyester fabrics. Being anionic biopolymer, tragacanth gum has resulted in outstanding zeta potential, polydispersity index, particle size and encapsulation efficiency with the values of − 38.1 mV, 0.2, 14.1 nm and 99%, respectively. The positively charged guar gum that interacted with aluminium chloride led to precipitation, which disfavoured retention and repellency properties. Based on correlation coefficient (R2) values for tragacanth gum (0.9832) and cationic guar gum (0.9761)-based nanoemulsions, the release of lemongrass essential oil from nanoemulsions follo..... 59 hits |
