— Shellac-Derived Hydroxy Acid
Molecular Formula C₁₆H₃₂O₅
Aleuritic acid — a naturally occurring trihydroxy fatty acid isolated from shellac resin. A rare, high-purity specialty chemical vital to perfumery, polymer synthesis, cosmetic formulation, and advanced research.
Purity Grade
Aleuritic acid (9,10,16-trihydroxyhexadecanoic acid) is a naturally occurring hydroxy fatty acid obtained by the alkaline hydrolysis of shellac resin. It is one of the principal aliphatic components of shellac, constituting a significant fraction of its polyester core.
With three hydroxyl groups along its C16 chain, aleuritic acid is a versatile bifunctional building block prized in synthetic chemistry, specialty fragrance, cosmetic actives, and biodegradable polymer research worldwide.
Trihydroxy Structure
Three hydroxyl groups (at C-9, C-10, and C-16 positions) enable rich reactivity — esterification, lactonization, and polymerization for advanced material applications.
Natural Origin
Derived exclusively from shellac resin through controlled hydrolysis. A renewable, bio-based raw material with a traceable, sustainable supply chain.
High Purity
Available at ≥98% purity for research, synthesis, and formulation applications. Consistent quality across batches with full analytical certification.
