Description
1-Undecanol (CAS 112-42-5) is a straight-chain fatty alcohol also known as undecanol, Tip-Nip, Neodol 1, and registered under FEMA 3097 for flavour applications. It carries no E-code designation. EC number 203-970-5 applies for regulatory identification within the EU.
In personal care formulations, 1-undecanol functions as an emollient and emulsion stabiliser by integrating into lipid bilayers to reduce interfacial tension and improve film cohesion on skin and hair. In food and fragrance applications, it contributes a mild, fatty-floral note at low concentrations and acts as a surface-active agent in flavour emulsions.
1-Undecanol is available in technical and cosmetic grades as a colourless liquid, supplied in drums and IBC containers. It is compliant with REACH registration requirements and is recognised under FEMA 3097 for flavour use. Buyers should confirm grade suitability against FCC or relevant pharmacopoeial standards for their application.
