1,12-Octadecanediol

1,12-Octadecanediol is a long-chain aliphatic diol with two hydroxyl groups positioned at the 1 and 12 carbons of an 18-carbon backbone. It is also known under trade names including Loxanol, Sovermol 912, and Alfol A, and carries the CAS number 2726-73-0. No E-code designation applies to this substance.

In personal care formulations, it functions as an emollient and humectant, helping to retain moisture at the skin surface while contributing to emulsion stability through its amphiphilic character. In polymer and lubricant systems, it acts as a plasticizer and internal lubricant, reducing intermolecular friction between polymer chains or metal surfaces by forming a structured boundary layer.

1,12-Octadecanediol is supplied in solid form and is subject to REACH registration requirements for quantities above one tonne per year within the European Economic Area. Procurement teams should confirm grade specification, purity documentation, and packaging format directly with the supplier, as these vary by production batch and intended application.
