N,N-diethyl-meta-toluamide (DEET), an insect repellent, can be successfully encapsulated in poly(n-butyl methacrylate-comethyl methacrylate) nanospheres via direct miniemulsion polymerization. Stable and low polydisperse nanospheres with a number average diameter of 114 AE 37 nm were obtained. It is shown that DEET is an effective costabilizer and that sodium lauryl sulfate is a suitable surfactant. The nanospheres glass-transition temperature (T g ) can be tuned by adjusting the ratio between n-butyl methacrylate and methyl methacrylate in the monomer formulation. The repellent reduced the polymerization reaction rate and the copolymer molecular weight, and changed the nanoparticle morphology. The release rate of the encapsulated DEET provides repellency for over 9 h and is and more controlled when compared to the free DEET. Results show the mechanism of release is temperature dependent. At temperatures close to and lower than the polymer T g , polymer relaxation is the limiting mechanism. At higher temperatures, Fickian diffusion limits the overall release. Thus, the DEET release rate can be tuned by adjusting the copolymer T g . This ensures this material a great potential as temperature-dependent delivery system. An alternative of protection for this vulnerable population is the encapsulation and further application of DEET in fabrics, for instance. Thus, not only the DEET would not be applied directly to the skin, but its evaporation could be slowed down, increasing the repellency time of this substance.The encapsulation of substances can be achieved with a large number of techniques, like coacervation, 8 solvent evaporation, 9 and polymerization techniques 10,11 and there is also a considerable variety of carrier systems, such as liposomes, polymeric nanocapsules, micelles, etc. [12][13][14] One advantage of using polymeric systems for encapsulation is the possibility of tailoring the polymer chain, which makes them suitable for a wide range of applications, like drug delivery, 15,16 controlled release of fragrances, 17-19 and cells encapsulation. 20,21 The miniemulsion polymerization is a simple technique which allows the formation of polymer particles with controlled Additional Supporting Information may be found in the online version of this article.

“…A number of thermal-responsive polymers have been designed as potential fragrance carriers. For example, nanoparticles formed by thermal-responsive poly(stearyl acrylate) have been fabricated and used for the thermal-induced release of fragrance [14]. The loaded fragrance can be released upon gentle heating near the temperature of human skin due to the reversible transition of the polymer chain from the ordered state to the disordered state at~45 • C.…”

Thermal Triggered Release of Menthol from Different Carriers: A Comparative Study

The design of appropriate thermally responsive fragrance carrier systems is of significant importance for the application of fragrance in the food and tobacco industries. In this study, we investigate the potential of sorbitan monostearate and guar gum for the stabilization of menthol under ambient conditions and the thermally-induced release of menthol. Our results show that the sorbitan monostearate carrier could well stabilize the menthol for at least up to 15 days with neglectable menthol loss due to the favorable binding of menthol on the sorbitan monostearate carrier. In addition, rapid and controlled release of menthol could take place at a temperature of 80 °C in the sorbitan monostearate carrier system. As a comparison, guar gum could not stabilize menthol as a result of its poor compatibility. Our results suggest that sorbitan monostearate can be an ideal carrier material for the support of fragrance. In addition, our results also provide a useful guide for the tailored design of thermally responsive fragrance carriers.

“…Plenty of fragrances play roles in antianxiety, antidepression, and stress-lowering through inhalation. − Nevertheless, free fragrances have some intrinsic defects. Fragrant molecules release rapidly because of their strong volatility, which shortens their useful lives and brings side effects to us in the heavy-scented condition. , Besides, traditional fragrant products are inconvenient, difficult to use, or just do not fit into people’s lives. Therefore, the keys to improving the regulating effect of fragrances on the central nervous system are elimination of their inherent deficiencies.…”

Aromatherapy is widely used in the treatment of diseases of the central nervous system, such as depression and anxiety. However, the rapid and uncontrolled release of aroma weakens the effects of aromatherapy. In this study, zwitterionic polymer-based nanoparticles encapsulated with linalool were prepared to improve the regulation of the central nervous system. First, the nanoparticles were modified with positive charges to adhere to the surface of silk via electrostatic interactions between the cationic nanoparticles and anionic silk. Besides, the fragrance was sustainably and controllably released from the nanoparticles. The effects of polymerization degree, polymer structure, and zeta potential on encapsulation efficiency, adhesion efficiency, and release profiles of linalool were then explored. The results showed that the linalool-encapsulated nanoparticles had the best performances of encapsulation, adhesion and release of fragrance when the polymerization degrees of hydrophilic block and hydrophobic block were 20 and 5, respectively. In addition, open field tests evaluated the regulation of nanoparticles on the central nervous system at the behavioral level. Measurements of dopamine, acetylcholine, and γ-aminobutyric acid expressions explored the mechanism of moderating effects on the central nervous system at the molecular level.
