Carbowax® is a proprietary formulation of Polyethylene Glycols (PEGs) and Methoxypolyethylene Glycols (MPEGs) manufactured by Dow Chemical. It is considered an intermediate chemical used to enhance the properties or processing of other formulations. The product is a water soluble mix of linear polymers (PEGs and MPEGs) with repeating oxyethylene groups. H–(OCH2CH2)n–OH is the general formula for polyethylene glycol and CH3–(OCH2CH2)n–OH is the general formula for methoxypolyethylene glycol. Carbowax® can improve the production and release of molded components, control the amount of foam produced during mixing processes, and can enhance a product's ability to lubricate, dissolve, or hold moisture. Carbowax® is available in various melting points and viscosity to suit the manufacturer's formulation requirements including increasing the product's ability to mix or blend well, modifying the product's melting or freezing range, enhancing the thickness or stickiness of products, and can change a product's evaporation rates.
