Description

Promulgen G is a high-purity, non-ionic emulsifier and stabilizer widely recognized for its excellent performance in pharmaceutical and cosmetic formulations. Its primary value lies in its ability to create stable emulsions and enhance the texture and bioavailability of topical products. This makes it an essential ingredient for manufacturers in the pharmaceutical, personal care, and cosmetic industries seeking reliable excipients for creams, ointments, and lotions.

Application

• As a primary emulsifier and stabilizer in pharmaceutical creams and ointments.
• Used in cosmetic formulations for lotions, moisturizers, and sun care products to ensure texture stability.
• Acts as a solubilizing agent for active pharmaceutical ingredients (APIs) in topical delivery systems.
• Employed in the formulation of dermatological preparations for its skin-friendly and non-irritating properties.
• Functions as a co-emulsifier alongside other surfactants to optimize emulsion droplet size and long-term stability.
• Utilized in veterinary pharmaceutical preparations for topical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
