Aleuritic Acid
Aleuritic acid — 9,10,16-trihydroxypalmitic acid — is the principal constituent acid of shellac — roughly a third of the resin — isolated by alkaline hydrolysis (saponification) of the resin. It is supplied as an off-white to cream powder or flakes, in technical and refined purities.
Its commercial importance rests on one remarkable role: it is the classical natural feedstock for macrocyclic musk synthesis (perfumery molecules such as ambrettolide, isoambrettolide and civetone), which makes it a staple raw material for fragrance-chemical manufacturers — many of them in China. Beyond perfumery it serves as an intermediate in specialty organic synthesis, polymer and bioplastic research, and pharmaceutical chemistry.
We are a merchant exporter based in Bihar, next to India's lac belt: we source aleuritic acid from established Indian shellac processors, check each lot against its COA, and handle the export paperwork. Every batch ships with a COA stating assay, acid value and hydroxyl value. For the chemistry and end uses, see aleuritic acid uses; for fragrance-house buying notes, see aleuritic acid in musk chemistry.

Aleuritic Acid — Common Questions
What is aleuritic acid used for?
Mainly as the natural starting material for macrocyclic musk fragrances such as ambrettolide, isoambrettolide and civetone. It is also used in specialty organic synthesis and research.
How is aleuritic acid made?
By alkaline hydrolysis (saponification) of shellac, followed by isolation and purification of the acid.
Which grades are available?
Technical and refined grades. The batch COA states the assay, acid value and hydroxyl value.
What is the minimum order quantity for aleuritic acid?
25 kg. Larger lots are quoted on the same terms; tell us the grade, quantity and destination port.
Can I get an aleuritic acid sample before a bulk order?
Yes. We send 100–500 g from the same process family as the bulk lot. The courier charge is deducted from your first order.
How is aleuritic acid packed and shipped for export?
In 25 kg fibre drums or HDPE-lined bags. Small lots go by air; larger lots by sea on FOB Kolkata, CFR or CIF terms, with COA, MSDS and TDS.
What is CAS 533-87-9?
CAS 533-87-9 is the CAS registry number of aleuritic acid, 9,10,16-trihydroxyhexadecanoic acid (also called 9,10,16-trihydroxypalmitic acid), formula C16H32O5, molecular weight 304.43.
What is the difference between technical and refined aleuritic acid?
Refined grade is purified further for a higher assay and paler colour and is the usual choice for fragrance musks and pharmaceutical chemistry. Technical grade suits polymer research and uses where a lower assay is acceptable. Both carry a batch COA stating the assay.
What documents come with aleuritic acid?
A batch certificate of analysis (assay, acid value, hydroxyl value, loss on drying, melting range), a safety data sheet, a technical data sheet and a certificate of origin.
How should aleuritic acid be stored?
In closed, lined drums or bags, in a cool and dry place away from direct heat. Shelf life is about 24 months under these conditions.
