Product Description
Product name: Stearyl Alcohol (1-Octadecanol)
Appearance: A long-chain fatty alcohol that is typically a waxy solid; confirm the offered physical form
Chemical identity: A defined C18 fatty alcohol, distinct from cetearyl alcohol, which is a mixed C16/C18 material with a different CAS. Molecular formula: C₁₈H₃₈O. CAS number: 112-92-5. EC number: 204-017-6
Industrial role: Used as a fatty-alcohol raw material in selected formulation and processing systems. Offered specification: Confirm C18 content, melting range, color, hydroxyl value, iodine value if relevant, and intended end use. Buyer information: State whether a defined C18 material or a C16/C18 mixture is required, plus target specification, quantity, destination, and documents
Compare this defined C18 alcohol with a C16/C18 mixture: Cetearyl alcohol (CAS 67762-27-0)
FAQ - Technical & Supply Chain
-
Q:
Are Stearyl Alcohol, 1-Octadecanol and Octadecyl Alcohol the same material?
A: Yes. These names normally identify the C18 fatty alcohol, CAS 112-92-5. It is not stearic acid or octadecylamine. Commercial grades can contain C16, C18 and C20 homologs, so the name alone does not define the chain distribution. -
Q:
Which specifications matter when purchasing Stearyl Alcohol?
A: Agree C18 content and homolog profile, hydroxyl value, acid value, iodine value, water, color, melting or solidification range and saponification or nonvolatile residue where relevant. State flakes, beads or another particle form and review the lot COA against the intended wax, surfactant or formulation specification.
