Polymer Composites, 2019
AbstractThe search for biodegradable materials motivated the development of new materials for the food industry. Biomaterials (pectin, starch, and chitosan) are considered promising biodegradable polymers for developing or improving materials. This study aimed to develop biodegradable bionanocomposite films with neem oil and carnauba wax nanoemulsion ...

Reproduction and subchronic feeding study of carnauba wax in rats
Food and Chemical Toxicology, 1983The reproductive performance of Wistar rats fed carnauba wax at levels of 0.1, 0.3 or 1% in the diet and the effects of subchronic administration of carnauba wax at these dose levels on the resultant progeny were studied. Reproductive indices, body-weight gain, food consumption, haematological and clinical chemical data, ophthalmic, gross and ...

Subchronic feeding study of carnauba wax in beagle dogs
Food and Chemical Toxicology, 1983Carnauba wax fed at levels of 0.1, 0.3 and 1% in the diet to beagle dogs for 28 wk did not produce evidence of toxicity or pathological effects. Body weight gain, food consumption, clinical chemical, haematological, and urine analysis data, and organ weights of animals fed carnauba wax were comparable with those of control animals.

Adsorption of radioactive ions on carnauba-wax aerosols
The European Physical Journal A, 1998A new method based on parallel aerosol size spectrometry and γ-spectrometry is introduced for the measurement of short-lived radioactive ions, fission products or super-heavy elements produced at accelerators. Furthermore a new aerosol generator is presented.

Volume charge distribution in carnauba wax electrets
Journal of Applied Physics, 1973Internal charge distribution in carnauba wax thermoelectrets was measured. It was found that substantial volume charges exist within the electrets. These charges form a characteristic permanent volume charge distribution which is essentially the same for all investigated (over 100) electrets regardless of the magnitude of the electric field used for ...

An investigation of the structures and molecular dynamics of natural waxes. II. Carnauba wax
Journal of Physics D: Applied Physics, 1988For pt.I see ibid., vol.21, p.1421 (1988). Structural aspects and the molecular dynamics of carnauba wax are reported. X-ray diffraction results show that it crystallises in an orthorhombic unit cell. DSC and proton spin-lattice measurements as a function of temperature revealed a premelting solid-solid transition at 335 K.

Carnauba wax—Product of a Brazilian palm
Economic Botany, 1952Carnauba occupies a leading position among vegetable waxes because of its hardness, good luster and high melting point, which make it especially desirable for floor polishes. The only source region of this important vegetable wax is northeastern Brazil.
