Ethylene Oxide Derivatives manufacture via a number of different processes using ethylene oxide, propylene oxide, glycols and other bases including alcohols and ammonia.
Ethylene oxide is produced by reacting ethylene with oxygen in the presence of a silver catalyst. Ethylene oxide is a highly reactive chemical, an intermediate in the production of a wide range of derivative chemicals, which have applications in a huge number of industrial and consumer products.
Ethylene oxide is a reactive chemical, and other derivatives it forms include ethanolamies on reaction with ammonia, which are used in gas processing, detergents and soaps and cement grinding. Reaction with alcohols forms glycol ethers, which in turn can be esterified to glycol ether esters, these solvents are used in paints and inks.
Ethylene glycols are the most well known derivatives of ethylene oxide. These are produced by hydration of ethylene oxide; monoethylene oxide is the largest volume product, with diethylene glycol and triethylene glycol as co-products. The glycols have similar chemical and physical properties and are all hygroscopic. They are used in applications such as plasticisers, humectants, solvents and gas processing. Monoethylene glycol and diethylene glycol are important chemical intermediates, used to manufacture polyester fibres and resins.
Other derivatives of ethylene oxide include polyethylene glycols for cosmetics, lubricants and plasticisers, and ethoxylates for detergents and surfactants.
Ethylene Oxide Derivatives are mainly used in pharma care products, industrial solvents, agro chemicals, construction chemicals, cosmetics, synthetic, lubricants, surface coating intermediates, oil gas recovery, paper and food processing, and biotechnology etc.
Derivatives of Ethylene Oxide are commonly used in the plastics industry for manufacturing bottles and to produce polyester fibers for clothing and furniture, automotive coolants, industrial coolants, heat transfer fluids, detergents and surfactants. Ethylene Oxide is also an intermediate used in the manufacture of flexible and rigid polyurethane foams, brake fluids and water-soluble solvents.

Ethoxylates, the essential precursor molecules for many of the most respected detergents and surfactants are available to customers worldwide. The ease of ethoxylation and sulphation by conventional means makes the derivatives suitable for a broad spectrum of surfactant applications.
Fatty Alcohol Ethoxylate
Fatty alcohols contain oxidized impurities, such as carbonyls. Under alkaline conditions, even trace levels of such impurities can condense and form chromophoric species. This is observed for the base-catalyzed ethoxylation of fatty alcohols.
Decolorization technologies have been developed which allow for:
- Pre-treatment of the fatty alcohol raw material
- Treatment during ethoxylation
- Post-treatment of the ethoxylate
Superior results are typically obtained by pre-treatment of the alcohol. Treatment during ethoxylation is also often a viable option.
House Hold Surfactants
The largest outlet for the polyoxyethlene alcohol in the future will be in the formulations of cleaners house hold and industrial use. They can be compound as liquid, powders, pastes, or brass depending upon the specific application, laundry-detergent formulation, automatic-dishwashing machine detergent, hand washing formulation, solid hard-surface (dry powder) formulation, floor cleaner and wax stripper (liquid) formulation and waterless hand cleaner formulation.
Scouring: In the textile-scouring operation for both natural and synthetic fibers, nonionic bases on alcohols have played a very important role. Wool-scouring, cottonkier biling-off of viscose, abd soaping off are example of the types of scouring operations.
Since the scouring operation removes the fats present in the initial material, materials have to be added back which will serve lubricants, softeners and antistatics for the cording, spinning and weaving operation, mineral oil and/or vegetable oil are used as lubricants.
Dyeing and Finishing:
The largest surfactant consuming stepin cotton processing is the dyeing and finishing step polyoxyethyxiene alcohol play an important role in this process. Owing to their action as penetrants, wetting agent, and dying assistants.
Nonionics are excellent emulsifiers for agriculture sprays because they are unaffected by hard water and by pH changes. The general types of agriculture sprays are the “ready-to-emulsify” hydrocarbon solutions of various insecticides and plant toxicants.
The number of use in the Paper industry, Rewetting agents. It is used to improve the absorbency of wet strength, paper i.e. paper towel. It is also used for the rapid penetration of treating solutions in to impregnated paper
It is excellent for rubber latex during the compound operations.
Normally leather goes through for basic processing operations degreasing tanning fat liquoring and finishing in each operation the used of surfactants particularly the Polyoxyethyene alcohol is helpful.
The use of waiting agents and emulsifiers in the emulsion polymerization of based latics is well known. The choice of a particular surfactants depends on the particular monomer beings reacted and the properties desired in the final emulsion. Polyoxyethyene alcohols as well as other nonionic are superior emulsifiers because of their tolerance for hard water.
Polyoxyethyene alcohol finds a number of uses in the manufacture of cosmetics raw material such as in shampoos, skin cleansers, skin compability, normal flors, antibacterial wash product most sodium layury/ether sulfate etc.
Fatty Acid Ethoxylate
On the basis of low foam capacity and low relative cost the polyoxyethylene ester of fatty acid have been one of the most attractive nonionic detergent activities on the market. In combinations with various types of builders these surfactants are formulations for all type of house hold and industrial cleaning application.
Such as laundering formulations, dishwashing formulations floor and wall clearing formulations, metal cleaning formulations, rug-cleaning compositions concrete floor cleaners, etc.
- Textile: Polyoxyethylene esters of fatty acids posses remarkably good emulsifying, lubricating dispersing and suspending power and these properties combined with their detergent and antistic characteristics indicate their potential in a variety of textile processing application.
- Agriculture: Surfactants are used primarily in the preparation of wettable poders and in the preparation of toxicant emulsions for insect control. Their relative insensitivity to hard water and use over a wide range of pH conditions make them excellent emulsifier. They can be used either alone or in conjunction with other surface active agents.
- Paper: Polyoxyethylene fatty acids are used as rewetting agent to improve the absorbency of wet-strength paper used in the manufacture of paper towel. The deinking of new print requires the use of a nonionic surfactant.
Fatty Amines Ethoxylate
Ethoxylated fatty amines are nonionic surfactants used as an emulsifier and in formulating emulsifier blends. Used as a wetting agents, dispersants, stabilizers, sanitizers and defoaming agents. End applications include agrochemical emulsifiers, industrial cleaners, metal cleaners, textiles, paper de-inking, drilling products and detergents. Used as an intermediate for the synthesis of anionic surfactants.
The amine ethylene oxide adducts have wide application in many of these application there can be an interchange of derivating from one series to another so no attempt will be made to separate application by product. However it is cationic properties that have extended the use of these compounds and have offered new and valuable means for solving many industrial problems. The very fact that most surface encountered be they metal mineral or plastics are negatively charged surface once absorbed the polyoxyethyene amines from a protective and tightly bound film which effectively will protect the surface against corrosion attack. This property is very important in petroleum refining operation. The continuous injection of small amounts of polyoxyethylated amine in to most refinery or producing units will protect metal surfaces against the attack of water, Hydrogen sulfide, hydrogen chloride, in grease oil, slushing compounded and cutting oil.
Besides metallic and mineral surface may organic surface absorb this cationic surface active material. Emulsions prepaid from these surfactants will readily exhaust emulsifier on to organic surface there by allowing the emulsions to break and deposits its organic phase on the surface. Frequently the water phase of these emulsions will then run off the surface allowing for a much more rapid setting time consequently a drying period is not needed. These emulsions may be applied to textile, leather, paper, plastic and painted surfaces. Other textile application include their use as dye assistants and leveling agents.
