food grade oil

A food grade compressor oil for use in a high pressure compressor includes a base oil, an N-acyl derivative of the amino acid sarcosine, an imidazoline, and an amine-phosphate. Each of the three additives comprises no more than 0.5% by weight of the oil composition, and results in high lubricity and very low corrosion even when water is present in the oil. The compressor oil may also include polybutene which serves as a thickener, and an antioxidant. The compressor oil of this invention is particularly well suited for use in a hypercompressor used in the manufacture of polyethylene.
Food Grade Oils are basically synthetic oils with high stability used in processing Food Grade Grease. Special type of Food Grade Gear Oils is required in maintaining gears in food process industry. A food grade oil composition, comprising: a base oil comprising at least 84% by weight of the oil composition; an N-acyl derivative of the amino acid sarcosine comprising from 0.2% to 0.5% by weight of the oil composition; an imidazoline comprising from 0.2% to 0.5% by weight of the oil composition; an amine-phosphate comprising from 0.2% to 0.5% by weight of the oil composition;an antioxidant; and a thickener. The food grade compressor oil as defined in claim 17, wherein the antioxidant comprises no more than 0.5% by weight of the oil composition and is selected from a group consisting of butylated hydroxy toluene, dibutylmethylphenol, and 2,6-Di-tert-butyl-para-cresol. The food grade compressor oil as defined in claim 1, wherein the base oil is a white oil comprising from 84% to 92% by weight of the oil composition. The food grade compressor oil as defined in claim 1, wherein each of the N-acyl derivative of the amino acid sarcosine, the imidazoline, and the aminephosphate comprises no more than 0.5% by weight of the oil composition . Food Grade Oil, commonly known as No-Tox HD Oil, is a series of multipurpose white mineral lubricating oils that are NSF H1 registered for use where incidental food contact may occur. No-Tox HD Food Grade Oil, available in 12 grades from ISO VG 15 to 1000, is designed to give exceptional anti-wear and rust and corrosion protection in a wide range of applications including hydraulic systems, gear cases, chains, compressors, bearings and circulating systems and other applications found in the “clean” industries such as food, beverage, pharmaceutical and personal care products.
