Description
Lauryl Stearate (CAS 5303-25-3, EC 226-150-9) is a fatty acid ester formed from lauryl alcohol and stearic acid, also referenced under the names Dodecyl Stearate and Dodecylstearat. It carries no assigned E-code and is classified under HS code 2915.70.0150. No standard abbreviation is in common industry use.
In personal care formulations, it functions as an emollient and emulsifier, reducing interfacial tension between oil and water phases to stabilise creams and lotions. In plastics processing, it acts as an internal lubricant and plasticizer, reducing polymer melt viscosity and improving surface release. Metalworking lubricant formulators use it to lower friction between metal surfaces under moderate load conditions.
Lauryl Stearate is supplied in powder to lump form and is subject to REACH registration requirements for EU commerce. Buyers should confirm grade specifications against intended application, as cosmetic-use material may require additional purity documentation. Standard industrial packaging applies; consult supplier for available lot sizes.
