Hydroxytyrosol
Hydroxytyrosol (CAS 10597-60-1) is the principal phenolic alcohol of the olive tree (Olea europaea) and the polyphenol most closely identified with the cardiovascular profile of olive oil.
The compound has the formula C₈H₁₀O₃ and a molar mass of 154.16 g/mol. It is a colourless to pale yellow viscous liquid or low-melting solid, very soluble in water, ethanol, and most polar organic solvents.
We source bulk Hydroxytyrosol from top China manufacturers for our partners. The manufacturer is in Zhejiang. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
Hydroxytyrosol grades run from a few percent in crude extracts to 99 percent or higher in isolated material.
Olive fruit and olive leaf extract grades typically contain 6 to 25 percent hydroxytyrosol, often blended with oleuropein, tyrosol, and verbascoside.
Concentrated grades at 40 to 80 percent are produced for capsule and softgel manufacture. Some suppliers offer water-soluble powders standardised to 20 or 40 percent on a maltodextrin or gum acacia carrier.
Synthetic hydroxytyrosol at 99 percent or higher is produced for pharmaceutical and reference use, with full impurity profiling. Liquid concentrates derived from olive mill wastewater are also available for beverage applications.

How We Help Source Hydroxytyrosol
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Hydroxytyrosol out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Hydroxytyrosol together with other ingredients such as Arachidonic Acid, Coenzyme Q10 and Chondroitin Sulphate Sodium into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Hydroxytyrosol is approved as a novel food in the European Union under Commission Implementing Regulation (EU) 2017/2470, covering synthetic hydroxytyrosol for use in fats and supplements at defined levels.
The EFSA cardiovascular health claim authorised under Regulation (EU) No 432/2012 reads that olive oil polyphenols contribute to the protection of blood lipids from oxidative stress, conditional on the food providing at least 5 mg of hydroxytyrosol and its derivatives (such as oleuropein complex and tyrosol) per 20 g of olive oil. This is the only authorised polyphenol health claim in the EU referenced to a single compound family.
In the United States, olive fruit and olive leaf extracts standardised to hydroxytyrosol are marketed as dietary-supplement ingredients under DSHEA, with several self-affirmed GRAS notifications covering food use.
Pharmacopoeial monographs do not yet exist for the isolate, although olive leaf monographs in the European Pharmacopoeia and the United States Pharmacopeia define oleuropein-based identity and assay tests.
Manufacturing Process
Three main routes account for current hydroxytyrosol supply.
The dominant natural route is recovery from olive mill wastewater and olive pomace, the residual streams of olive oil pressing in Spain, Italy, Greece, and Tunisia. Hydroxytyrosol is concentrated in the aqueous phase and is extracted by adsorption on macroporous resin or by membrane separation, followed by acid or enzymatic hydrolysis of the parent oleuropein to release the free phenol.
A second route extracts olive leaf, which is rich in oleuropein. Hydrolysis under controlled acid or enzymatic conditions converts the secoiridoid into hydroxytyrosol and elenolic acid, which are then separated chromatographically.
The synthetic route condenses 3,4-dihydroxybenzaldehyde or 3,4-dimethoxyphenylacetic acid through standard reductive steps to yield racemic hydroxytyrosol. The synthetic material is identical to the natural compound, which lacks chirality.
Final material leaves the plant as a liquid concentrate, a powder on a food-grade carrier, or a crystalline solid depending on grade.
