“…Many methods have been used for the preparation of polymer capsule such as interfacial polymerization [8], phase inversion precipitation [9,10] in-situ polymerization [11] and solvent evaporation [12]. Among of them, solvent evaporation is one of the most famous methods due to its simplicity.…”

The microencapsulation of jasmine oil with polymethyl methacrylate (PMMA) was carried out by solvent evaporation method in oil in water (O/W) emulsion system. The oil phase was formed by the mixing of PMMA, jasmine oil and toluene and then dispersed in polyvinyl alcohol solution as stabilizer. After solvent evaporation, PMMA microcapsules with encapsulated jasmine oil were formed. The influence of weight ratio of PMMA:jasmine oil on the preparation of polymer capsule was studied. It was found that using 1:1 weight ratio of PMMA:jasmine oil, the polymer capsules could not prepared. The increase of PMMA content resulting in the formation of spherical PMMA microcapsules as in the case of 2:1 and 3:1 weight ratios. The amount of encapsulated jasmine oil and the encapsulation efficiency was measured with UV-visible spectroscopy. Approximately 72% encapsulation efficiency was obtained.

“…Pena et al [70] studied polysulfone microcapsules loaded with vanillin, but the EE% was determined with only one molecule considered as a tracer. [70] Li et al [19] prepared chitosan microparticles encapsulating orange oil, and also calculated the EE% with one major component of the mix. It is the first time that encapsulation of a mix of seven molecules in SLNs is reported.…”

Solid lipid nanoparticles (SLNs) loaded with perfume were prepared using a hot homogenization process coupled with ultrasounds. The objective was to develop a simple process adjustable to several kinds of lipids. The process comprised two steps: a pre-emulsion of the melted lipids in water followed by a size reduction by sonication, before cooling. The study of several formulation parameters showed that the size distribution of SLNs depended essentially on the sonication step, and especially on the ultrasounds power and time. Five types of SLNs loaded with perfume were produced, based on petrolatum, candelilla, shea butter, C10-18 triglycerides, and cetyl palmitate. The size distribution was below 200 nm with a narrow size distribution. Moreover, high encapsulation efficiency was obtained, at least 66.5% (±0.5) for petrolatum SLNs and 94.9% (±0.5) for cetyl palmitate SLNs and the loading % was comprised between 4.9% (±0.5) (petrolatum) and 7.0% (±0.5) (cetyl palmitate). A correlation between the partition coefficient of the molecules and the encapsulation efficiency was established for all lipids except cetyl palmitate. Cetyl palmitate, candelilla and petrolatum SLNs were stable for at least one month at 4°C and 25°C.

“…The time required for the shell synthesis varies from 4 to 24 h also the level of sophistication required which may affect the nanosphere size [14,16,17]. The selection of shell material is decided from the type of bulk medium in which active molecule is to be delivered.…”

“…For the specific applications, fragrance delivery requires a carrier to hold the fragrant molecules and possess prolonged responsive controlled release. For this reason encapsulation of fragrant molecules was studied by many researchers using chitosan [14], bovine serum albumin [15] and polymers [8,16].…”

The present work deals with encapsulation of fragrance molecule in inorganic nanocontainers substrate and investigation of its prolonged release at different pH condition. The nanocontainers used were aluminosilicate clay (Halloysite) having cylindrical shape with outside diameter in the range of 30-50 nm, 15 nm lumen and length equal to 800 ± 300 nm. Rosewater absolute was used as a sample fragrance for loading in nanocontainer and delivery purpose. The fragrance loaded nanocontainers were coated with a thin layer of polyelectrolyte i.e. Polyacrylic Acid (PAA). The structural characteristics of prepared nanocontainers were determined by using Fourier Transform Intrared Spectroscopy (FTIR), Thermal Gravimetric Analysis (TGA) and UV spectroscopy analysis. Release of fragrance molecules in the aqueous medium was monitored for 24 h. The fragrance release was found to be responsive as the amount of fragrance release increases with increase in pH value from 3 to 7. Fragrance release has been studied by using various permeation kinetic models such as zero order, first order, Hixson-Crowell, Higuchi, Korsmeyer-Peppas and Hopfenberg models. Korsemyer-Peppas shows the best fit (R 2 = 0.9544) compared to other kinetic model for the release of fragrance from nanocontainers.
