Our Products
Chemical Building Blocks,
Made Reproducible
Every product we ship is defined by a specification we can defend: assay by HPLC or titration, controlled impurity profile, documented residual solvents and a full traceability chain from raw material to drum. Batch-to-batch consistency is the product.
p-Hydroxybenzoic Acid
Precursor for parabens and liquid crystal polymers. Low residual solvent, consistent particle size, batch-to-batch reproducible.
Acetophenone
Versatile aromatic ketone used in APIs, fragrances and photo-initiators. Available in 200 kg drums and ISO tanks.
Resorcinol
Dihydroxybenzene used in tyre adhesion resins, UV absorbers and flame retardants. Flake or prill form.
Adipic Acid
Dicarboxylic acid for nylon 6,6, plasticisers and food-grade applications. 25 kg bags, 1000 kg jumbo bags.
Oleuropein
Olive-leaf secoiridoid with antioxidant and anti-inflammatory activity. Water-soluble powder, food and cosmetic grades.
Hydroxytyrosol
High-purity olive polyphenol for nutraceutical and skincare formulations. Available as powder or 20% solution.
Resveratrol
Japanese knotweed derived stilbene, GMO-free, solvent-residue controlled. Kosher and Halal options on request.
