OUR PRODUCTS
Our AFYNERIE® technology produces a family of 7 organic acids, 100% biobased: carboxylic acids containing from 2 to 6 carbon atoms. We manufacture our high-quality products through fermentation using biomass, and we achieve more than 99% purity for certain applications. This wide range of biobased high-quality acids enables AFYREN to enter diversified and global markets.
Our methodology
Our natural molecules are drop-ins, identical to the petroleum-based molecules that industries use, thereby rendering them simply and immediately replaceable. Our 100% biobased acids allow our clients to reduce their environmental impact without affecting the performance of their products.
ACETIC ACID
Acetic acid is a two-carbon organic carboxylic acid that exists in nature. In the industrial market, acetic acid can be produced both synthetically and through fermentation. AFYREN propose a 100% biobased high purity acetic acid that can be used in various applications, from household cleaning to preservation and fragrance formulations.
Did you know?
Acetic acid is the principal component of vinegar and gives it its typical sourness. In application as a natural flavoring substance, it can be used in the formulation of butter, cheese, chocolate, grape and strawberry flavors.
It is widely used as a raw material for the production of a range of acetates with applications in flavors and fragrances.
PROPIONIC ACID
Propionic acid is a three-carbon organic carboxylic acid naturally present in the stomachs of ruminants. It is widely used as a mold inhibitor, both for food and for feed. Several attempts to produce biobased propionic acid, but failed before industrial scale production, AFYREN offers the first 100% biobased propionic acid on the market.
Did you know?
Propionic acid has an acidic profile, and the resulting propionic acid esters have a fruity smell. They can be used as natural flavoring substances or as solvents in many flavor and fragrance applications.
Propionic acid is mainly used in bread and bakery products as a mould inhibitor. It is either introduced with the yeast or sprayed onto the bread to prevent moisture from penetrating the loaf.
BUTYRIC ACID
Butyric acid is a four-carbon organic carboxylic acid naturally present in the stomachs of humans and certain dairy products. Transformed, it is extensively used in several applications such as cellulose acetate butyrate, aromas, and building-block in pharmaceuticals.
The traditional industrial process is based on petrochemistry, whereas AFYREN offers a biobased alternative to this acid with a reduced carbon footprint.
Did you know?
Butyric Acid is a feed material that is being used in animal feed formulations. This product is well known for its properties which support the reduction of the inflammation inside of an animal digestive tract. As such it enables the feed industry to provide alternative solutions to reduce the medication in livestock. (That way the end consumer gets an animal product without antibiotic residues).
ISOBUTYRIC ACID
Isobutyric acid is a four-carbon organic carboxylic acid and an isomer of butyric acid. It naturally occurs in specific trees and flowers. Often used in cosmetics and fragrances, AFYREN’s 100% biobased Isobutyric acid is an added value for our customers.
Did you know?
Isobutyric acid and its volatile esters occur naturally in a wide variety of foods. It has a strong, buttery odour and a fruity taste when diluted. It has many applications as a natural flavoring substance for creamy-fruity tastes. It is also a raw material for the production of natural fruit flavorings.
Isobutyric acid esters are used in cosmetic products and flavorings and perfumes.
VALERIC ACID
Valeric acid is a five-carbon organic carboxylic acid that is widely used in esters for synthetic lubricants in refrigeration and in aeronautics turbines. Historically, valeric acid has always been produced through an oxo-process with no biobased alternative. AFYREN offers 100% biobased valeric acid.
Did you know?
Valeric acid is a minor constituent of the perennial flowering plant Valerian (Valeriana officinalis), from which it takes its name. It has a very strong, penetrating, acidic odour and a pleasant fruity taste when diluted. Its main use is the synthesis of its esters. The salts and esters of valeric acid are known as valerates or pentanoates and are widely used in cosmetics and perfumes.Valeric Acid is a crucial component of Polyol Esters formulations that are used in applications of refrigeration and air conditioning such as industrial refrigeration, refrigeration systems for food storage or mobile and stationary air conditioning.
ISOVALERIC ACID
Isovaleric acid is a five-carbon organic carboxylic acid and an isomer of valeric acid. Reformulated and transformed, isovaleric acid can be used in flavors and fragrances, and other applications.
Did you know?
Isovaleric acid, an isomer of valeric acid, is useful in the production of nut and coffee flavors as well as butter, cheese, strawberry, etc. The resulting esters, such as ethyl isovalerate, are widely used in fruit, cheese, nut and other flavors.
CAPROIC ACID
Caproic acid is a six-carbon organic carboxylic acid also known as hexanoic acid. AFYREN offers biobased, GMO-free and palm oil free caproic acid – unique on the market.
Did you know?
Caproic acid gets used in particular lubricant formulations in order to manage the viscosity level of the final lubricant. These lubricants are being used as Heat Management liquids in battery cooling for Electronic Vehicles.
