Description

Isostearyl Glycolate is a high-purity, multifunctional ester derived from isostearyl alcohol and glycolic acid. This compound is valued for its excellent emollient properties and ability to enhance the sensory profile of formulations, providing a smooth, non-greasy feel. It is a key ingredient for manufacturers in the personal care and cosmetic industries seeking to develop premium skin care products, sunscreens, and color cosmetics with superior texture and stability.

Application

• Primary emollient and skin-conditioning agent in facial creams, lotions, and serums.
• Texture enhancer and spreading agent in sun care products (sunscreens, after-sun lotions).
• Key component in decorative cosmetics (foundations, lipsticks) for improved pigment dispersion and smooth application.
• Formulation aid in anhydrous systems and oil phases to improve stability and sensory characteristics.
• Ingredient in high-end hair care products (conditioners, serums) for added shine and manageability.
• Base material for specialty esters and derivatives used in niche cosmetic applications.

Quality Control

Our Isostearyl Glycolate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and appearance are provided to guarantee consistent quality and traceability for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent degradation. Keep away from strong oxidizing agents.
