Esters

Esters are the reaction product between an alcohol and a carboxylic acid. This definition brings a wide variety of products. We have broken the range down according to the starting alcohol type.

Esters - items

Monoalcohol Esters

Monoalcohol esters are the reaction product of a monovalent alcohol and a fatty acid. Variation in both the alcohol part (hydrophilic) and the fatty acid (lipophilic) results in a difference in polarity. This results in a wide range of applications in many different sectors.

Methyl esters

Methyl esters are the reaction product of methanol and a natural fatty acid. Depending on fat feedstock, different chain lengths are obtained. Although methylesters are often used as an intermediate, the are also recognised as green solvents for different applications. With their low viscosity they are also used to reduce the viscosity of more viscous liquids, such as vegetable oils.

Ethyl esters

Ethyl esters are the reaction product of ethanol and a natural fatty acid. Within our range we have one standard, which is used as a solvent in pharmaceutical applications.

Isopropyl esters

Isopropyl esters are the reaction product of isopropanol and a natural fatty acid. Depending on fat feedstock, different chain lengths are obtained. Isopropyl esters do not only exhibit lubrification properties, they also have a high solubility for essential oils.

Butyl esters

2-Ethylhexyl esters

Decyl esters

Cetyl esters

Stearyl esters

Oleyl esters

Ethylene glycol esters

Ethylene glycol esters are the reaction product of monoethylene glycol and a fatty acid.

Glycerol esters

Glycerolmonoesters

Glycerol monoesters are the reaction product of glycerin and fatty acids. Although the name suggests otherwise, glycerol monoesters are always mixtures of monoesters, diesters and triesters, with the concentration of monoesters dominating. Often used as emulsifiers, they are indispensable emulsifiers in many industries. Their natural properties and low toxicity make them favoured products in the production of cosmetics, food products and animal feeds.

Glycerol triesters

PEG esters

PET esters

Pentaerythritol esters are the reaction product of the tetravalent alcohol pentaerythritol and natural fatty acids.

Propylene glycol esters

Sorbitan esters

Sorbates

Sorbitan esters are non-ionic emulsifiers obtained by the esterification of dehydrated sorbitol with fatty acids. These esters are mostly water-in-oil emulsifiers, but they can also act as oil-in-water emulsifiers when they are used in combination with the ethoxylated sorbitan esters. Sorbitan esters are used in cosmetics, lubricants, textiles etc.

Polysorbates

Ethoxylated sorbitan esters are obtained by the ethoxylation of sorbitan esters. They are more hydrophylic than the sorbitan esters themselves and are used as non-ionic emulsifiers and solubilising agents for water insoluble active products and essential oils. In combination with the non-ethoxylated sorbitan esters, they can be used as emulsifiers for oil in water emulsions. Ethoxylated sorbitan esters are used in cosmetics, detergents, lubricants and textile applications.

Trimethylolpropane esters

Trimethylolpropane esters are the reaction product of the trivalent alcohol trimethylolpropane and natural fatty acids. The structure of the alcohol makes them more resistant to hydrolysis than other esters.

Polyglycerol esters

Polyglycerolesters are emulsifiers and solubililizers made out of renewable feedstocks. Polyglycerol is produced with glycerin which is obtained by the hydrolysation of vegetable oils.
