PEG 400 Ester surfactants are manufactured by reacting a polyethylene glycol with a fatty acid. 
The polyethylene glycol 400 comprises the hydrophilic part of the surfactant and the fatty acid the lipophilic part. 
By varying the molecular weight of the PEG and the fatty acid, surfactants covering a wide range of HLB values can be produced. 
Typically, those with an HLB below 13 are oil soluble and water dispersible while those above are water soluble.

PEG Esters as Alternatives to Nonylphenol Ethoxylates

The environmental effects associated with NPE’s are now well documented and their replacement by alternatives is being strongly encouraged.

It is considered that PEG oleate surfactants are a closer match to NPE’s with respect to solubility and emulsifying characteristics than are alcohol ethoxylate surfactants.

Fatty acid esters
Fatty acid esters are used in a wide range of industries for their lubricating properties, solvency and resistance to oxidation. 
They are becoming more popular due to their renewable content, as they are derived from sources such as vegetable oils and animal tallow. 
Fatty acids esters have low volatility compared with many traditional solvents, making them suitable as replacements for solvents in coatings, inks and pressroom cleaners, as well as in lubricants and metalworking fluids.

ATAMAN’s esters are made by the reaction of fatty acids with alcohols.

The process of combining an organic acid (RCOOH) with an alcohol (ROH) to form an ester (RCOOR) and water is called esterification. 
This chemical reaction results in the formation of at least one ester product with formation of water as the by-product is termed esterification process.

Esters are formed by the reaction of an alcohol and an acid under basic or acid conditions. 
Esters have a wide range of applications in every industry segment. 

Some examples are glycol esters with fatty acids, methoxy PEG esters & methyl ester ethoxylates, glycerol esters (GMO, GMS, GTS, GML, GTO) sorbitan esters (SMO, SMS, SML, STO, STS, SorbitansesquiOleate) and polyglycerates( eg; polyethylene glycerol mono oleate).

PEG esters are formed by the reaction of polyoxyethylene glycol (X-moles) with a fatty acid. Such esters are generally water soluble and behave as emulsifiers. 
ATAMAN offers mono and di esters based on lauric acid, stearic acid and oleic acid with PEG 400, PEG 400, PEG 600, PEG 1000, PEG 1500, PEG 4000 and PEG 6000. They do not hydrolyse in water and prevent mould growth, therefore preferred in products containing water (eg. Cosmetic creams etc.) some of their applications: PEG esters are widely used in the formulation of emulsifier blends, thickeners, resin plasticizers, emollients, pacifiers, spreading agents, wetting and dispersing agents and viscosity builders. They also have applications in metal working, pulp, paper, textiles and defoamers for latex paints.

Glycerol monostearate or glycerinmonostearate (GMS) or monostearin, is a monoglyceride commonly finding use as an emulsifier in foods. Chemically it is the monoglycerol ester of stearic acid. GMS is a food additive used as a thickening, emulsifying, anticaking, and preservative agent; an emulsifying agent for oils, waxes, and solvents; a protective coating for hygroscopic powders; a solidifier and control release agent in pharmaceuticals; and a resin lubricant. It is also used in cosmetics and hair-care products. It is generally a white, odorless, and sweet-tasting flaky powder that is hygroscopic.

Stearin or glyceryl tristearate or tristearoylglycerol or Glycerol trioctadecanoate is a triglyceride that is composed of glycerol in which all three hydroxy groups have been esterified with stearic acid (octadecanoic acid). It finds application as hardening agent in the manufacture of candles and soap. It also has a role as a plant metabolite. It is a common constituent of animal and vegetable fats.

Monolaurin, also known as glycerol monolaurate, glyceryl laurate or 1-lauroyl-glycerol, is a monoglyceride. It is the mono-ester formed from glycerol and lauric acid. Its chemical formula is C15H30O4. Monolaurin is most commonly used as a surfactant in cosmetics, such as deodorants. As a food additive it is also used as an emulsifier or preservative. Monolaurin is also taken as a dietary supplement. Monolaurin is currently sold as a dietary supplement and is categorized in the United States by the Food and Drug Administration as generally recognized as safe (GRAS).

Monooleoylglycerol, also known as glyceryl 1-oleate, glycerylmonooleate or 1-monoolein, is classified as a member of the 1-monoacylglycerols. 1-Monoacylglycerols are monoacylglycerols containing a glycerol acylated at the 1-position. Monooleoylglycerol is considered to be practically insoluble (in water) and relatively neutral. It is an yellow to amber liquid at room temperature, biodegradable and can be used as a water-in-oil emulsifier, pigment dispersant, lubricant, and spreading agent.

PEG fatty acid esters are used as components of cosmetics such as bath oils, cleansing preparations, moisturizers, other skin care preparations, shampoos, and sunscreen products, with concentrations typically ranging from 0.1% to 10% of the product. 
PEG 400 oleate (CAS Reg. No.9004-96-0 ) is approved as a secondary direct food additive when used as a component of defoamers for certain foods under 21 CFR 173.340. 
Certain PEG fatty acid esters are also approved as indirect food additives for use in resinous and other coatings, paper and cardboard products, and textiles under various regulations in 21 CFR Parts 175-178

The PEG fatty acid ester structure is that of a mono- or diester of polyethylene glycol with certain monobasic carboxylic acids [typically as derived from animal and vegetable fats and oils (e.g., oleic acid)] with carbon chains that are even-numbered and range from eight to 22 carbons. 
The physical and chemical characteristics of PEG fatty acid esters are dependent upon the actual chemical structure, with their surfactant properties being based on the hydrophilic polyethylene glycol and the hydrophobic fatty acid ester portions of the molecule. Differences in the degree of esterification, the length of the polyethylene glycol moiety and the carbon chain length of the fatty acid moiety provide for a range of surfactant properties.
The PEG fatty acids are reported to be liquids or low melting point solids that are either soluble or dispersible in water.

Agricultural Uses of PEG Fatty Acids
The uses of PEG fatty acids in pesticide formulations includes defoamers, dispersing agents, emulsifiers, granule coatings, solvents/cosolvents, suspending agents, wetting agents, as well as general surfactants and related functions

PEG 400 monooleate is used in cosmetic formulations, as an emulsifier in lotions and bath oils, in PVC plastisols as a viscosity modifier and in metals as a metal working agent and lubricant. It is also used as a defoamer in water treatment.
