Glycerol is a popular alcohol used within the food, pharmaceutical, and personal care industry. Glycerol (or glycerine) is listed in over 2,000 products, such as toothpaste, mouthwash, and pain relief medication due to its desirable properties to act as a humectant, preservative, and lubricant. It is prepared from fats and oils and also as a by-product from biofuel production. Demand for glycer...

The aim of this study was to investigate antibacterial effects of oregano and thyme essential oils (EOs) on some food-borne bacteria. GC-MS analysis of EOs was performed in order to determine their composition and phenols were predominant constituents. The investigation of the antibacterial effects of EOs was performed on Salmonella Enteritidis, Salmonella Thyphimurium, Staphylococcus aureus, m...

the rapid expansion in world production of palm oil over the last three decades has attracted the attention of the oils and fats industry. oil palm gives the highest yield of oil per unit of any crop. palm oil is the major oil produced, with annual world production in excess of 50 million tonnes. throughout the world, 90% of palm oil is used for edible purposes (e.g., margarine, deep fat frying...

Oily sludge is one of the most significant solid wastes generated in the petroleum industry. It is a complex emulsion of various petroleum hydrocarbons (PHCs), water, heavy metals, and solid particles. Due to its hazardous nature and increased generation quantities around the world, the effective treatment of oily sludge has attracted widespread attention. In this review, the origin, characteri...

Dip-coated films, which are widely used in the coating industry, are usually measured by capacitive methods with micrometric precision. For the first time to our knowledge, we have applied an interferometric determination of the evolution of thickness in real time to nonvolatile Newtonian mineral oils with several viscosities and distinct dip withdrawing speeds. The evolution of film thickness ...

The metal fmishing industry uses over 40 production processes to produce a wide range of metal products. Waste streams generated include wastewater, waste oils, spent solvents, and spent process solutions. Current1,v a wide variety of techniques which minimize waste are available. Cost-effective methods to reduce electroplating wastewater contamination include water conserv&ion and drag-out red...

The wood protective action of citrus wax, a waste from the citrus industry that is a mixture of citrus fruit epicuticular waxes and essential oils, was evaluated against the termite Cryptotermes brevis Walker (Isoptera: Kalotermitidae). The antifeedant index (AI) of the total wax and fractions was calculated. The total citrus wax exhibited an AI₅₀ value of 24.69 mg/cm³, the wax after hydrodisti...
