The product identified by the CAS number 421-85-2 is a type of chemical known as a polypropylene glycol ether (PGE). It is a colorless, practically odorless, non-staining, water soluble liquid with a faint ammonia-like odor. It is miscible with a variety of organic solvents, is insoluble in mineral oils, and can be used for a wide variety of industrial applications.
As an industrial chemical, polypropylene glycol ethers are typically used as solvents, cleaning agents, surfactants, and dispersants, due to their hydrophilicity (water solubility) and low toxicity. They are used in a number of industries, including pharmaceuticals, textiles, plastics, organic synthesis and coatings. They are also used as ingredients in personal care and consumer cleaning products, such as soaps, floor cleaners, and fabric softeners.
In the pharmaceutical industry, polypropylene glycol ethers are known to have a number of unique properties, such as lower vapor pressure and higher flash points, making the solvents suitable for a wide range of processes. They are also known to be noncorrosive, non-reactive and relatively non-toxic. Additionally, they have low volatility, low odor, and low flammability, making them an excellent choice as an industrial cleaning agent.
In the textile industry, polypropylene glycol ethers are mainly used to improve the elasticity, sheen and strength of fabrics. They are also used to help soften, brighten and remove soil from fabrics. In the plastics industry, polypropylene glycol ethers are used to reduce viscosity and improve flow properties in plastic resins, allowing the resin to become more stable when exposed to high temperatures.
In conclusion, polypropylene glycol ethers are widely used in a variety of industries as industrial solvents, cleaning agents, dispersants, and surfactants due to their hydrophilic (water-soluble) properties, low volatility, low odor, low flammability, and relatively low toxicity. CAS number 421-85-2 can be used to identify this chemical product.
