Description

Isobutyl Icosanoate is a high-purity, long-chain fatty acid ester derived from isobutyl alcohol and eicosanoic (arachidic) acid. This specialty ester is valued for its excellent emollient properties, stability, and ability to enhance texture and spreadability in formulations. It serves as a key functional ingredient for manufacturers in the personal care, cosmetics, and lubricant industries seeking superior performance and skin feel.

Application

• Cosmetic & Personal Care Emollient: Used in creams, lotions, and sunscreens to impart a non-greasy, silky-smooth texture and improve skin barrier function.
• Hair Care Conditioning Agent: Incorporated into conditioners, serums, and styling products to provide lubrication, reduce frizz, and enhance shine.
• Lipstick & Makeup Formulations: Acts as a binder and texture modifier in lipsticks, foundations, and color cosmetics for improved application and wear.
• Pharmaceutical Topicals: Serves as a penetration enhancer and emollient base in ointments, creams, and dermatological preparations.
• Specialty Lubricants & Release Agents: Employed in high-performance synthetic lubricants and mold release agents for its thermal stability and low volatility.
• Plasticizer & Processing Aid: Functions as a secondary plasticizer and internal lubricant in polymer processing to improve flexibility and flow.
