Description

Choleth-10 is a non-ionic surfactant belonging to the polyoxyethylene cholesteryl ether family, derived from cholesterol. This compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a versatile ingredient in sophisticated formulations. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and cosmetic industries seeking high-performance, skin-compatible excipients and emollients.

Application

• As a solubilizer and emulsifier in topical pharmaceutical creams, ointments, and lotions.
• As a key conditioning agent and emollient in high-end skincare products, such as anti-aging serums and moisturizers.
• As a stabilizer and texture enhancer in cosmetic formulations, including foundations and sunscreens.
• As a component in liposomal drug delivery systems to improve bioavailability.
• As a surfactant in specialized industrial and laboratory applications requiring mild, non-ionic properties.

Quality Control

Our Choleth-10 is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and performance consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, hydroxyl value, and water content. We support compliance with cGMP and ICH guidelines for pharmaceutical applications.

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 hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
