In addition to our own product range, we offer as well contract manufacturing. Please visit our CMO homepage for more information.
Depending on the raw material, production and purification process, NaturalSpecialities has developed a large range of tannins, suitable for different markets:
Our products
The word tannin covers a wide variety of products, usually classified in two families: the condensed and the hydrolysable tannins. In nature the condensed tannins are the most abundant and can be found – usually at low concentrations – in a large number of plant genera. Our grape seed extracts belong to this family of tannins.
Hydrolysable tannins are far less abundant and only a limited number of plants contain sufficient amounts of these products to be of commercial value. In this family, the distinction between ellagitannins and gallotannins can be made. Wood extracts, like for example oak extract or chestnut extract belong to the group of the ellagitannins.
NaturalSpecialities is the world leader in the production of gallotannins or tannic acid. Only 4 botanical raw materials can be used for the production of gallotannins:
- Aleppo Gallnuts - Quercus infectoria
- Chinese Gallnuts - Rhus semialata
- Sumac leaves - Rhus coriaria, typhina
- Tara pods - Caesalpina spinosa

Pharma
The medicinal use of tannins dates back thousands of years. Use of gallotannins in pharma applications include:
- Anti-diarrhoea compositions
- Excipients for API-tannates
- Inflammatory skin conditions
The Alsok range is in correspondence with different Pharmacopoeias. Please contact our Application Department for any question about the usage of our gallotannins for pharmaceutical purposes.
PGG
Hydrolysable tannins are mixtures of polygalloyl glucoses and/or polygalloyl quinic acid oligomers with a degree of polymerisation in between 3 and 12. Consequently commercial tannic acid is mixtures of dozens of closely related yet different entities.
Although in some applications this distribution is an advantage, for specific pharmaceutical end-uses this is clearly not the case as knowledge of these impurities is an absolute prerequisite.
To address these problems, NaturalSpecialities developed a procedure to separate pentagalloylglucose (PGG) from its tannic acid matrix with purity over 95%. PGG is an excellent alternative for hydrolysable commercial tannic acids due to its similar physico-chemical properties but without the ill-defined composition.

Nutraceuticals
NaturalSpecialities has developed a range of grape seed extracts suited for all applications and budgets.
OmniVin 20R can be used as a very strong polyphenolic radical scavenger alone or in combination with anti-oxidants, e.g. vitamin C or E. It is claimed that synergistic effects can be obtained when using such ingredients together. In cost sensitive formulations the use of OmniVin 10R or OmniVin R is recommended.
Both OmniVin 20R and OmniVin WG are used in cosmetic skin-care formulations to impart anti-oxidant or anti-ageing effects to lotions or creams. It is also useful as an adjuvant in sun-screen formulations where it can help reduce UV induced skin damage.

Textile
Flock finishing
Most of the flock activation systems used today for both AC and DC applications are tannin based processes, guaranteeing good and long-lasting activity, superior flock density and good handling properties.
NaturalSpecialities has developed a full range of gallotannins (Floctan range), offering the guarantee of an efficient process for the preparation of moisture stable conductive flocks from nylon, rayon and polyester, etc.
Backtanning
The fastness of dyed goods toward (repeated) washing, chlorine bleaching and fastness against staining has become increasingly important in response to increased consumer and retailer demands.
Although synthetic alternatives are on the market, gallotannins are clearly better performing. NaturalSpecialities has created specifically for this market the Textan range.

Technical
Rust conversion
The Tanex range of products is widely used in the formulation of acidic rust converter formulations. They can be used to formulate both resin-free pre-treatment solutions and acid-compatible water based film forming formulations.
By binding and converting poorly adhering iron oxides into more stable iron tannate complexes tannic acid based pre-treatments improve anti-corrosion resistance of new or old cast iron or iron work surfaces.
Boiler water treatment
The following tannic acid properties are of concern for water treatment purposes:
- Oxygen scavenging
- Preventing scale formation
- Metal complexation
The Tanex range combines these 3 properties in one product, therefore allowing for simple formulated end products containing as few raw materials as possible.
