Ethylene Oxide FAQs
What is Ethylene oxide?
Ethylene oxide is a flammable, colorless gas at temperatures above 51.3 ºF (10.7 ºC) that smells like ether at toxic levels. Ethylene oxide is found in the production of solvents, antifreeze, textiles, detergents, adhesives, polyurethane foam, and pharmaceuticals.
Where the Ethylene oxide is mainly used?
Ethylene oxide is used mainly as a chemical intermediate in the manufacture of textiles, detergents, polyurethane foam, antifreeze, solvents, medicinals, adhesives, and other products and also used as a fumigant, a sterilant for food (spices) and cosmetics, and in hospital sterilization of surgical equipment and plastic devices that cannot be sterilized by steam.
Which are the derivates of Ethylene oxide?
Some of Ethylene oxide derivates are Fatty Alcohol Ethoxylate, Fatty Acid Ethoxylate, Fatty Amines Ethoxylate, Alkyl Phenol Ethoxylate, Castor Oil Ethoxylates, Hydrogenerated Castor Oil Ethoxylates, Glycerine Ethoxylates, Polyethylene Glycols, Monoethylene Glycol, Diethylene Glycol, Triethylene Glycol, Ethylene Glycol Ethers, Ethanolamine, Silicon Oil Emulsifier, Amino Oil Emulsifier, Paraffin Wax Emulsifier, Non-Ionic Self Emulsifying Wax etc.
What is the color of Ethylene oxide?
Ethylene oxide is a colorless gas with a sweet odor.
What is Emulsion?
A dispersion of droplets of one liquid in another, immiscible liquid, in which the droplets are of colloidal or near-colloidal sizes.
What are the types of Emulsion?
- Oil-in-water (o/w): The continuous phrase is water dispersed oil droplets.
- Water-in-oil (w/o): The continuous phrase is oil dispersed water droplets.
How can ethylene oxide harm workers?
In addition to eye pain and sore throat, exposure to Ethylene oxide can cause difficult breathing and blurred vision. Exposure can also cause dizziness, nausea, headache, convulsions, and blisters and can result in vomiting and coughing. Ethylene oxide is also linked to spontaneous abortion, genetic damage, nerve damage, peripheral paralysis, muscle weakness, as well as impaired thinking and memory. In liquid form, Ethylene oxide can cause severe skin irritation upon prolonged or confined contact.
What is Ethoxylate?
Ethoxylation is a chemical process in which ethylene oxide is added to fatty acids in order to make them more soluble in water.
What is emulsifier?
An agent that acts to stabilize an emulsion. The emulsifier may make it easier to form an emulsion and to provide stability against aggregation and possibly against coalescence.
What is demulsifier?
A chemical used to break emulsions (that is, to separate the two phases). The type of demulsifier selected depends on the type of emulsion, either oil-in-water or water-in-oil. Demulsifiers are used in the chemical analysis of oil and synthetic muds and to treat produced hydrocarbons.
What does a surfactant actually do?
Surfactants are also referred to as wetting agents and foamers. Surfactants lower the surface tension of the medium in which it is dissolved. By lowering this interfacial tension between two media or interfaces (e.g. air/water, water/stain, stain/fabric) the surfactant plays a key role in the removal and suspension of dirt. The lower surface tension of the water makes it easier to lift dirt and grease off of dirty dishes, clothes and other surfaces, and help to keep them suspended in the dirty water. The water-loving or hydrophilic head remains in the water and it pulls the stains towards the water, away from the fabric. The surfactant molecules surround the stain particles, break them up and force them away from the surface of the fabric. They then suspend the stain particles in the wash water to remove them.
What does a surfactant "look like"?
A tadpole! A surfactant consists of a hydrophobic (non-polar) hydrocarbon "tail" and a hydrophilic (polar) "head" group. This appearance is the key to its behavior. The dirt-loving or hydrophobic tail absorbs to the oil and grease in dirt and stains.
