1,2-Decanediol

1,2-Decanediol (CAS 1119-86-4) is a straight-chain diol derived from decanoic acid, commercially known under trade names such as SymClariol. It carries no assigned E-code and is catalogued under EC number 214-288-2 with the molecular formula C10H22O2.

In personal care formulations, 1,2-Decanediol functions as a multifunctional preservative booster by disrupting microbial cell membranes, reducing the required concentration of primary preservatives. In pharmaceutical and cosmetic emulsions, its moderate hydrophilicity allows it to act simultaneously as a humectant and co-emulsifier, improving moisture retention and stabilising oil-water interfaces.

This material is supplied as a white solid and is available in cosmetic and pharmaceutical-grade specifications, with compliance documentation supporting REACH registration requirements. It is not subject to FCC or Ph.Eur. monographs. Standard packaging formats for B2B supply include fibre drums and multi-layer bags, with HS code 29053995 applicable for European import and export.
