Description

Benzoic Acid, Undecyl Ester is a high-purity organic ester compound, also known as undecyl benzoate. This specialty chemical serves as a versatile intermediate and functional ingredient, valued for its specific lipophilic character and stability. It is primarily utilized in the fragrance, cosmetic, and specialty polymer industries where precise molecular properties are required for formulation performance and product consistency.

Application

• Fragrance and Perfumery: Acts as a fixative and solvent for fragrance oils, contributing to longer-lasting scent profiles in fine perfumes and personal care products.
• Cosmetic Formulations: Used as an emollient and skin-conditioning agent in creams, lotions, and lipsticks, offering a smooth texture and enhanced spreadability.
• Plasticizer and Polymer Additive: Functions as a specialty plasticizer or processing aid in select polymer systems to modify flexibility and workability.
• Chemical Synthesis: Serves as a key building block or protecting group intermediate in organic synthesis for pharmaceuticals and agrochemicals.
• Lubricant and Grease Additive: Employed as a component in synthetic lubricants and functional fluids for its thermal stability and compatibility.
• Industrial Solvent: Used as a solvent for resins, inks, and coatings where a high-boiling, non-reactive medium is required.
