Ethylene Glycol Propyl Ether is used as a solvent in the coating industry and printing inks.
Today Ethylene Glycol Propyl Ether is reserved for only a few specific applications.
Ethylene Glycol Propyl Ether has been industrially replaced by other similar solvents.
Ethylene Glycol Propyl Ethers are inert to light metals such as aluminum or magnesium.
However, slow surface corrosion is observed at the boiling point.
Ethylene Glycol Propyl Ether vapors can form explosive mixtures with air (flash point 51 °C, ignition temperature 230 °C).
The compound reacts violently with strong oxidizing agents.
Ethylene Glycol Propyl Ether is a colorless liquid with an ether-like odor.
Ethylene Glycol Propyl Ether evaporates quickly and is completely soluble (mixes easily) in water.
Ethylene Glycol Propyl Ether is a propylene oxide-based, or Pseries, glycol ether.
Ethylene Glycol Propyl Ether is commercially available as a mix of two isomers.
1-Propoxy-2-propanol is the major isomer comprising at least 95% of the mixture, while 2-n-propoxy-1-propanol makes up the remaining 5%.
Ethylene Glycol Propyl Ether, is a solvent which is low toxic, environment-friendly and low viscous, is widely used in electrophoreticpaint, organic synthesis of medicine and pesticide (such as bactericide, parasiticide, weedicide, etc. ), adhesion agent, spice retention agent and plasticizer.
Ethylene Glycol Propyl Ethers are propylene oxide-based, more hydrophobic, have lower surface tension and lower toxicity, and work well in higher pH systems.

The Ethylene Glycol Propyl Ether most commonly encountered industrially are colorless liquids that have mild ethereal odors.
Alkyl glycol ethers are manufactured in a closed, continuous process by reacting ethylene oxide with an anhydrous alcohol in the presence of a suitable catalyst. Depending on the molar ratios of the reactants and other process parameters, the product mixtures obtained contain varying amounts of the monoethylene, diethylene, triethylene, and higher glycol ethers.
Typically, the products in these mixtures are separated and purified by fractional distillation.
The miscibility of most of these ethers with water and with a large number of organic solvents makes them especially useful as solvents in oil–water compositions. Their relatively slow rate of evaporation also makes them useful as solvents and coalescing agents in paints.
Other uses include inks, cleaners, chemical intermediates, process solvents, brake fluids, and deicers.
The ethers of the higher glycols are used as hydraulic fluids.

Odor and Appearance of Ethylene Glycol Propyl Ether
Ethylene Glycol Propyl Ether is a name for a large group of chemicals.
Most glycol ether compounds are clear, colorless liquids.
Some have mild, pleasant odors or no smell at all; others (mainly the acetates) have strong odors.
The common belief that glycol ethers never evaporate fast enough to create harmful levels in the air is false.
Some evaporate quickly and can easily reach hazardous levels in the air; others evaporate very slowly and therefore are less hazardous by inhalation.
Ethylene Glycol Propyl Ethers are widely used industrial solvents.
Each of them may be used alone, or as an ingredient in products such as coatings (paints, varnishes, dyes, stains, inks, and semiconductor chip coatings), cleaners (for degreasing, drycleaning, film cleaning, and circuit board manufacture), jet fuel de-icing additives, brake fluids, and perfumes and cosmetics.
Ethylene Glycol Propyl Ethers enter your body when they evaporate into the air you breathe, and they are rapidly absorbed into your body if the liquids contact your skin.
Cases of poisoning have been reported where skin contact was the main route of exposure, even though there was no effect on the skin itself.
The effects of overexposure can include anemia, mild intoxication (somewhat like the effects of drinking alcohol), and irritation of the skin, eyes, nose, and throat. Ethylene Glycol Propyl Ethers are hazardous to the male and female reproductive systems.
Ethylene Glycol Propyl Ethers, as described herein, can be used to formulate stable liquid cleaning compositions having a pH of less than 10, to improve the treatment of hydrophobic stains from surfaces, especially delicate surfaces.
Compositions comprising such glycol ether solvents have been found to be particularly suited for treating hydrophobic stains selected from oils, fats, polymerized grease, and mixtures thereof.
Ethylene Glycol Propyl Ethers are used as a solvent in the coatings industry and in printing inks.
Today Ethylene Glycol Propyl Ether is only reserved for a few special applications.
Ethylene Glycol Propyl Ether has been replaced industrially by other similar solvents.
Ethylene Glycol Propyl Ethers are inert towards light metals such as aluminum or magnesium.
However, slow superficial corrosion can be observed at the boiling point.
Glycol ethers are considered a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol.
These solvents typically have higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols.
The glycol ether product family is made up of more than 30 different types of solvents that can be categorized into two major groups, E-series and P-series, depending upon the starting material used (ethylene or propylene).
E-series comprises ethylene glycol butyl ether, ethylene glycol propyl ether, and ethylene glycol butyl ether acetate as key products.
These are used extensively as they have strong compatibility with diverse organic solvents and water.
They also have low volatility and strong solvent properties.
Thus, they are employed in applications in cosmetics, pharmaceuticals, electronics, and personal care.
P-series is majorly used in products that are used in treating metal and non-metal surfaces, laboratory products, and water treatment formulation.
Glycol ether helps in the formation of a proper film during coating cure and acts as an active solvent in resins.
It helps in optimizing the evaporation rate of the solvent in a coating.
It is also helpful in improving the flow out characteristics of the paint, and in eliminating brush marks during painting.
Ethylene Glycol Propyl Ether is widely used in personal care products and cosmetics in the formulation of skin & hair products, shampoos, personal cleanliness products, and bath products.
Global cosmetics business may surpass $450 million by 2025, with gains at over 4.5%.
Rise in per-capita disposable income along with change in lifestyle with increasing demand for skin care products owing to varying climatic conditions should boost industry growth.
Rapid rise in personal care sector due to increasing consumer consciousness regarding health hygiene may accelerate the glycol ether market share.
Ethylene Glycol Propyl Ethers are organic compounds produced from the reaction of propylene oxide with alcohols that are base catalysed.
Alcohols include but are not limited to methanol, ethanol, propanol, butanol, and phenol.
Higher glycol ethers can be produced from the subsequent reactions with additional propylene oxides.
Ethylene Glycol Propyl Ethers use comparable handling procedures that are similar with other common industrial solvents.
These can be stored in carbon steel containers.
However, if there is slight discoloration or there is trace iron contamination, phenolic-lined drums of stainless steel tanks should be considered as storage tanks.
Ethylene Glycol Propyl Ethers is used as intermediate of the herbicide preochlor.
Ethylene Glycol Propyl Ether is soluble in organic solvents such as ethanol,acetone, and miscible with water. With low toxicity low viscosity, so it also widely used in electrophoretic paint, organic synthesis of medicines (fungicides, insect repellants, herbicides, etc.).
Ethylene Glycol Propyl Ethers used with water to break the emulsion of an oil-base or synthetic-base drilling fluid to prepare the sample for chemical titrations to determine lime, calcium or chloride content according to API testing procedures.
PNP is an abbreviation for propylene glycol normal propyl ether.
It is an environmentally friendlier replacement of a xylene-isopropynol mixture previously used in certain titrations.
