“…We propose herein a new encapsulation route based on the formulation of double emulsions [32,33] and more precisely fragrance-in-water-in-perfumery solvent that allows the compartmentalization between the polymerization locus and the fragrance and we vary the proportion and type of cross-linker. Capsules were synthesized by free radical polymerization of the intermediate water phase of a double fragrance-in-water-in-oil emulsion containing monomers, cross-linkers and initiator.…”

“…Capsules were synthesized by free radical polymerization of the intermediate water phase of a double fragrance-in-water-in-oil emulsion containing monomers, cross-linkers and initiator. The direct fragrance-in-water emulsion was stabilized with Tergitol 15-S-12 a hydrophilic surfactant (HS) and the inverted water-in-oil emulsion by Polyglycerol polyricinoleate (PGPR) a lipophilic surfactant (LS) [32]. Two monomers were chosen: Oligo(ethyleneglycol) methacrylate (OEGMA) and the Methacrylamide (MAM) [33].…”

This paper describes a new route to synthesize polymeric capsules with interesting and diverse diffusive and mechanical properties. Such capsules were obtained by free radical cross-linking copolymerization of the intermediate water phase of a double oil-in-water-in-oil (O/W/O) emulsion. Such a strategy allows separating the locus of polymerization from the fragrance-containing compartment. Indeed fragrance molecules are known to be reactive. The encapsulated species, also corresponding to the innermost oil, was a model fragrance composed of more than 10 various molecules usually used in perfumery. In a first step, the double emulsion containing a hydrophilic monomer, either Methacrylamide or Oligo(ethyleneglycol) methacrylate, and a hydrophilic cross-linker, either Tetra(ethyleneglycol) diacrylate or N,N-Methylene-bis-Acrylamide, was formulated. The influence of the cross-linker agent on the feasibility of the double emulsion was examined. Then, in a second part, the polymerization was performed. Four different systems of capsules were developed and compared in terms of diffusive and mechanical properties. We show that changing the monomer /cross-linker couple allowed modulating the capsule properties.

“…Although PS is important for emulsion stability, it is also important to determine the particle size distribution (polydispersity). Determination of droplet size distribution usually requires dilution of emulsions (≤1% v/v), which may itself alter their size distribution, especially in highly concentrated, polydisperse or marginally stable systems [16]. PS of polydisperse emulsions is characterized by the measurement of both the mean droplet size and the size of their distribution [17].…”

Physical characterization and permeability of lupeol by use of organogel-based emulsions (o/w)

Lupeol, is naturally occurring compound present in plants, with some beneficial health effects. In the present study, organogel-based emulsions (o/w) were obtained from canola oil. Particle size analysis, rheology test, optical microscopy, and permeability of nutraceuticals by cell culture and UPLC-MS/MS were done. Particle hydrodynamic diameters obtained in organogel-based emulsions loaded with nutraceuticals were <200nm, Polydispersity Index (PdI) was around 0.25-0.4, and Zeta Potential (ZP) was about -19 to -25mV. Droplets in emulsions presented spherical shapes and adjusted to the Herschel-Bulkley model. Interestingly, permeability of lupeol was increased compared with its crystalline; therefore organogel-based emulsions loaded with lupeol have potential for controlled delivery of this nutraceutical.

Encapsulation has emerged as a vitally important tool for protecting the integrity of critical chemicals and improving the delivery mechanisms of natural/synthetic drugs, enabling the controlled release of ingredients and the maintenance of their chemical, physical, and biological properties. It is well known that essential oils (EOs) provide a valuable alternative for food preservation, as they help reducing the deterioration of foodstuffs as well as the proliferation of pathogens. Nevertheless, EOs are highly volatile and lipophilic, rendering them insoluble in aqueous systems. In addition, their secondary metabolites are extremely susceptible to environmental factors such as humidity, temperature, light, and oxygen. Therefore, encapsulation of EOs is an innovative option not only for preserving these substances but also for promoting their stability, controlling their release, and optimizing their efficiency and bioavailability. In this sense, this review aimed to describe current techniques and approaches used to incorporate natural hydrophobic compounds, covering EOs. It also examines whether encapsulation technology can be used efficiently in drug discovery and development. Studies have shown that microencapsulation, the use of nanoparticle, and liposomal are the most effective techniques for encapsulating EOs. Other encapsulation systems included spray drying, coacervation, and emulsification.
