Description

Citricacid,Dioctadecylester is a high-purity, long-chain diester derivative of citric acid, specifically designed for applications requiring enhanced lipophilicity and thermal stability. This compound serves as a versatile intermediate and functional additive, offering superior performance in formulations where compatibility with non-polar matrices is critical. It is particularly valuable for manufacturers in the polymer, personal care, and specialty lubricant industries seeking to modify material properties or introduce specific functionalities.

Application

• As a plasticizer and compatibilizer in PVC and other polymer systems to improve flexibility and processing.
• As a key intermediate in the synthesis of specialized surfactants and emulsifiers for industrial applications.
• As a lubricant additive and viscosity modifier in synthetic oils and greases.
• As a lipophilic component in cosmetic and personal care formulations, such as creams and ointments.
• In the production of corrosion inhibitors and metalworking fluid additives.
• As a stabilizer in various chemical processes to control reaction kinetics or product degradation.
