Propylene glycol is an approved food additive for dog and sugar glider food under the category of animal feed and is generally recognized as safe for dogs, [66] with an LD 50 of 9 mL/kg. The LD 50 is higher for most laboratory animals (20 mL/kg). [ 67 ]
Ethylene glycol may also be one of the minor ingredients in screen cleaning solutions, along with the main ingredient isopropyl alcohol. Ethylene glycol is commonly used as a preservative for biological specimens, especially in secondary schools during dissection as a safer alternative to formaldehyde. It is also used as part of the water-based ...
Polyethylene glycol is also commonly used as a polar stationary phase for gas chromatography, as well as a heat transfer fluid in electronic testers. PEG is frequently used to preserve waterlogged wood and other organic artifacts that have been salvaged from underwater archaeological contexts, as was the case with the warship Vasa in Stockholm ...
Many types of food are specially formulated to achieve water activity in the IMF range. Food ingredients are mixed with salt and/or sugar, and additives (such as propylene glycol and potassium sorbate) and then subjected to processing methods such as cooking, extrusion or dehydration to result in an intermediate moisture final product. Examples ...
Diethylene glycol (DEG) is an organic compound with the formula (HOCH 2 CH 2) 2 O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol. [3] DEG is a widely used solvent. [4]
Glycerol monostearate, commonly known as GMS, is a monoglyceride commonly used as an emulsifier in foods. [3] It takes the form of a white, odorless, and sweet-tasting flaky powder that is hygroscopic. Chemically it is the glycerol ester of stearic acid. It is also used as hydration powder in exercise formulas.
Additives are used for many purposes but the main uses are: Acids Food acids are added to make flavors "sharper", and also act as preservatives and antioxidants. Common food acids include vinegar, citric acid, tartaric acid, malic acid, folic acid, fumaric acid, and lactic acid.
Polypropylene glycol or polypropylene oxide is the polymer (or macromolecule) of propylene glycol. [1] Chemically it is a polyether , and, more generally speaking, it's a polyalkylene glycol (PAG) H S Code 3907.2000.
