Description

Butyl 12-Hydroxyoctadecanoate is a high-purity ester derivative of 12-hydroxystearic acid. This specialty chemical serves as a versatile intermediate and functional additive, valued for its unique combination of hydrophobic and hydroxyl functionalities. It is primarily utilized in the formulation of advanced lubricants, plasticizers, and personal care products where specific rheological and surface-active properties are required.

Application

• As a viscosity modifier and lubricity enhancer in synthetic greases and metalworking fluids.
• Functioning as a specialty plasticizer for polymers requiring low-temperature flexibility and improved compatibility.
• Used in the synthesis of cosmetic esters and emollients for skin creams and lotions.
• As a key intermediate in the production of more complex surfactants and emulsifiers.
• Employed as a processing aid and internal lubricant in plastics and rubber compounding.
• Potential use as a corrosion inhibitor component in protective coatings and formulations.
