“…Colloidal type of MCC contains 11.3%-18.8% of CMC, which can thicken the water phase between the oil globules so that the droplets are unable to move freely due to changes like interactions between droplets. 53,54,56 However, MCC with a concentration of 1.5% shows different results between commercial MCC Vivapur ® MCG 811 F, MCC HCl , and MCC MA , as shown in Figure 7. MCC commercial was still stable in low concentrate condition, whereas Figure 8 shown that MCC HCl was slowly creaming while for MCC MA did not form an emulsion, since it immediately separates into two phase after homogenized, indicates that MCC HCl and MCC MA are not able to maintain the stability of oil in water emulsion at low concentration as MCC Vivapur ® MCG 811 F. This is in line with the observations of the viscosity of each MCC, where MCC MA has the lowest viscosity compared to the other MCCs so reducing its ability to thicken the water phase in the oil globules so that the emulsion instantly separates into two phase.…”

“…The mechanism of MCC in providing O/W emulsion stability is by increasing the viscosity and forming a mechanical barrier, thus prevent the oil and water phase approach so provide long‐term stability to the O/W emulsion, where the viscosity increases with increasing the concentration of MCC used. Colloidal type of MCC contains 11.3%–18.8% of CMC, which can thicken the water phase between the oil globules so that the droplets are unable to move freely due to changes like interactions between droplets 53,54,56 . However, MCC with a concentration of 1.5% shows different results between commercial MCC Vivapur® MCG 811 F , MCC HCl , and MCC MA , as shown in Figure 7.…”

“…51 The hydroxyl groups on the surface of MCC act as hydrophilic, which will be wetted by the water phase, and the crystals part of MCC act as hydrophobic, which will be wetted by the oil phase. [51][52][53][54] All the MCC samples added to the O/W emulsion were stable for 3 months. The creaming or precipitate was not found after 3 months of storage with the addition of MCC with a concentration of 5% from total oil weight (Figure 6).…”

“…O/W emulsion with MCC is classified as a Pickering emulsion, an emulsion that is stabilized by solid colloidal particles and the properties of these systems are due in part to the irreversible nature of such particle adsorption 51 . The hydroxyl groups on the surface of MCC act as hydrophilic, which will be wetted by the water phase, and the crystals part of MCC act as hydrophobic, which will be wetted by the oil phase 51–54 . All the MCC samples added to the O/W emulsion were stable for 3 months.…”

Microcrystalline cellulose (MCC) is a modification of natural cellulose derived from plants or fermentation products such as nata de coco, by increasing the crystallinity, aspect ratio, surface area, dispersion, and biodegradability through the acid hydrolysis process, which is widely used in the food sector and pharmaceuticals. The variables of the methods and hydrolysis reagents used will affect the characteristics of MCC. The objective of this study was to determine the characteristics of MCC from nata de coco using different acids consisting of two treatments which are hydrolysis with 2.5 N hydrochloric acid (MCC HCl ) and 62.5 wt% maleic acids (MCC MA ). The results showed that the use of different hydrolysis reagents produced different MCC characteristics.Hydrolysis of cellulose with hydrochloric acid produced MCC with a higher crystallinity index, degradation temperature, particle size, and zeta potential value but the decomposition temperature was lower than that of MCC from maleic acid. Both MCC have a narrow particle size distribution and an irregular shape with a more uneven fiber surface texture of the MCC MA and contain C O and C C groups that are not present in MCC HCl . The viscosity of MCC HCl combined with carboxymethyl cellulose (CMC) 12% was higher than that of MCC MA under the same conditions, where the addition of both MCC with a concentration of 5% into the oil-in-water emulsion (O/W) showed good stability for 3 months, but at a concentration of 1.5% showed with creaming in the O/W emulsion with MCC HCl and no O/W emulsion was formed with MCC MA . Both MCC without the addition of CMC showed better characteristics than commercial MCC.

“…Remarkably, Pickering emulsion is an emulsion which replaces the traditional surfactant‐stabilized emulsion system with solid particles, and has high stability, anti‐agglomeration, and anti‐austenification 17‐19 . In recent years, nanocellulose as fibrous nanoparticle for stabilizing the Pickering emulsion has increasingly attracted the attention of researchers 20‐22 .…”

Both poly(methyl methacrylate) (PMMA) and polystyrene (PS) have excellent transparency, but a blend of the two typically has low mechanical properties and poor transparency owing to phase separation. Herein, oil-in-water Pickering emulsion gel technology was combined with the hot pressing process to prepare cellulose nanofibrils (CNFs) reinforced PMMA/PS binary blend composite film materials (CNFs/PMMA/PS). The CNFs/PMMA/PS composites with a pebble-shaped structure had a unique three-dimensional crosslinked network structure and endowed the composite film with better thermal stability, and excellent transparency and mechanical properties. Particularly, the derivative thermogravimetry and differential scanning calorimetry results revealed that the compatibility between the PMMA and the PS phases in the composite film is remarkably improved. The optimal tensile strength (58 MPa) and maximum strain (4.2%) were obtained when the content of CNFs was 52%, which represented approximately 3-fold and 2-fold improvements, respectively, than those of the PMMA/PS blend films. Moreover, the C-CNFs/PMMA/PS composite films maintained an excellent light transmittance of approximately 80% in the wavelength range of 600 to 800 nm. The facile preparation method is proposed to achieve an excellent dispersion of unmodified CNFs in hydrophobic and binary polymer mixture, which constitutes a new approach for using CNFs to enhance the high performance of polymer materials.
