“…Encapsulation of active ingredients, including flavors in polymer shell of urea-formaldehyde [1]- [4] and melamine-formaldehyde has been versatile [5]- [8]. Control of fragrance diffusion by barrier system of various types has been employed in fragrance prolongation, for instance, cyclodextrin host [9]- [10], solid-lipid nanoparticles [11], amphiphilic-crosslinked polymer network [12], double emulsion system [13], synthetic polymers formed by miniemulsion polymerization [14], coacervation with various carbohydrates [15]- [17], polymer blends [18] and multilayer microcapsules [19]. However, increasing in capacity of fragrance in urea-formaldehyde and melamine-formaldehyde is necessary to prolong the release period.…”

Abstract-Microcapsules of single-shell melamine-formaldehyde (MF) and double-shell urea-formaldehyde/melamine -formaldehyde (UF/MF) microcapsules loading with fragrance of varied concentrations were prepared using in situ polymerization. The microcapsules were analyzed using Scanning electron microscope (SEM) and Fourier transform infrared spectrometer (FT-IR). Loading capacity of fragrance in the microcapsules in term of percent weight of fragrance was determined using soxhlet extraction. From SEM images, shapes and sizes of single shell MF microcapsules were different depending on concentrations of fragrance and SDS added in the preparation procedure. FT-IR spectra of double-shell UF/MF microcapsules loaded fragrance presented absorption band of C=O at 1674 cm -1 as found in that of fragrance. Percent weight of fragrance in single-shell UF and double-shell UF/MF microcapsules substantially increased with increased concentration of fragrance. Additionally, loading capacity of fragrance in double-shell UF/MF microcapsules were higher than those in single-shell MF microcapsules at the same concentration of fragrance. This would lead to higher prolongation of fragrance release from double-shell UF/MF microcapsules than single-shell MF microcapsules and fulfill the end use applications.

“…Eucalyptus oil, derived from different species within the Eucalyptus tree genus, is principally composed of eucalyptol, a monocyclic terpene with an ether bridge between carbons 1 and 8 (Sansukcharearnpon, Wanichwecharungruang, Leepipatpaiboon, Kerdcharoen, & Arayachukeat, 2010), along with other minor ether, aldehyde and ketone components. It has been widely used in difficult to control the droplet size obtained by this method that results in a very broad droplet size distribution being obtained.…”

“…Camphor oil extracted from camphor tree can be used for multi-functional finishing of textile due to its myriad bio-medical activities for analgesic, antidepressant, antiinflammatory, carminative, hypertensive, insecticide and vulnerary action [1][2][3]. However, high volatilization of camphor oil greatly limits its application in textile finishing.…”

“…However, high volatilization of camphor oil greatly limits its application in textile finishing. To control the release rate of camphor oil on textiles, many methods have been developed, for example, sol-gel immobilization [4], cyclodextrin finishing [1,5], encapsulation in porous materials [6], encapsulation with polymers [2,7], emulsion polymerization [6], etc.…”

Camphor oil/latex dispersions were prepared by miniemulsion polymerization with a reactive emulsifier for the purpose of controlling camphor oil release. The prepared dispersions were characterized by dynamic light scattering method, transmission electron microscope and thermogravimetric analyses. The result indicates that camphor oil/latex dispersions had high stability and excellent ability for the control release of camphor oil. The volatility of camphor oil was averted after entrapping into the latexes. The particle size of the camphor oil/latex dispersion was approximately 89.4 nm and uniformly distributed when the dispersion was prepared at the conditions of that mass content of monomer (molar ratio of MMA to BA 2:3) to the dispersion 7.5 %, mass ratio of camphor oil to monomer 6 %, mass ratio of DNS-86 to monomer 20 %, molar ratio of AIBN to monomer 1.5 %, and mass ratio of HD to monomer was 2.5 %.
