Description

Cholesteryl Isostearyl Carbonate is a high-purity, synthetic ester derivative of cholesterol, valued for its exceptional emollient and skin-conditioning properties. This compound matters for formulators seeking to create premium, non-greasy textures with enhanced spreadability and a luxurious skin feel. It is primarily needed by manufacturers in the personal care and cosmetics industries for high-end skincare, sun care, and color cosmetic formulations.

Application

• Premium Skincare Emollient: Imparts a smooth, silky after-feel in anti-aging serums, moisturizers, and night creams.
• Color Cosmetic Stabilizer & Binder: Enhances pigment dispersion and improves the wear and texture of foundations, lipsticks, and eyeshadows.
• Sun Care Formulations: Used in sunscreens and after-sun products for its skin-conditioning benefits and compatibility with UV filters.
• Hair Care Conditioners: Provides lubrication and shine in leave-in conditioners and hair serums without heavy residue.
• Pharmaceutical Topicals: Serves as a penetration enhancer and emollient base in medicated creams and ointments.
• Makeup Removers & Cleansing Oils: Contributes to a rich, non-drying cleansing experience that helps maintain the skin barrier.

Quality Control

Our Cholesteryl Isostearyl Carbonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting HPLC assay, melting point, and specific optical rotation are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider an inert atmosphere (nitrogen blanket). Keep away from strong oxidizing agents.
