Description

Ethylhexyl Isostearate is a high-purity, synthetic ester derived from isostearic acid and 2-ethylhexanol. This versatile emollient is prized for its exceptional skin feel, providing a non-greasy, silky-smooth texture with excellent spreading properties. It is a key ingredient for formulators in the personal care and cosmetics industry, serving as a premium emollient, solvent, and carrier oil. Its chemical stability and compatibility with a wide range of ingredients make it indispensable for creating high-performance lotions, creams, sunscreens, and color cosmetics.

Application

• Personal Care & Cosmetics: Primary emollient in facial creams, body lotions, and anti-aging serums for a superior dry, silky skin feel.
• Sunscreen & SPF Formulations: Acts as a solvent and dispersant for organic UV filters, improving spreadability and water resistance.
• Color Cosmetics: Used in foundations, lipsticks, and mascaras to enhance pigment wetting, improve texture, and reduce tackiness.
• Hair Care Products: Provides conditioning and shine in hair serums, leave-in treatments, and styling products without weighing hair down.
• Pharmaceutical Topicals: Employed as a base or carrier in ointments and medicated creams for its excellent skin penetration and non-irritating properties.
• Industrial Lubricants & Release Agents: Functions as a synthetic lubricant component or mold release agent due to its thermal stability and low volatility.
