For professionals in the chemical, pharmaceutical, and cosmetic industries, a thorough understanding of key ingredients is essential for innovation and product development. n-Docosanol, identified by CAS 661-19-8, is a fascinating compound with a dual profile: it serves as a potent antiviral agent and a valuable component in cosmetic formulations. This overview aims to provide a clear picture of its properties, uses, and the best practices for sourcing this important chemical.

Chemically, n-Docosanol is a long-chain saturated fatty alcohol, specifically a primary alcohol with 22 carbon atoms (C22H46O). It presents as a white solid, typically in pellet or tablet form, with a melting point range of 65-72°C. Its insolubility in water means it is often incorporated into formulations that can accommodate its lipidic nature, such as emulsions or oleaginous bases. These physical and chemical properties dictate its functionality in various applications.

The pharmaceutical sector recognizes n-Docosanol primarily for its antiviral efficacy. It has been clinically proven to inhibit the replication of the herpes simplex virus (HSV), particularly in topical applications for conditions like cold sores. By impeding viral entry into host cells, it offers symptomatic relief and can potentially accelerate healing. For pharmaceutical companies, n-Docosanol represents a key active ingredient or intermediate for developing antiviral treatments. Sourcing pharmaceutical-grade material from reputable manufacturers is critical for ensuring efficacy and safety.

In the cosmetic industry, n-Docosanol is prized for its emollient properties, contributing to skin softness and smoothness. It also functions as a binder, helping to hold cosmetic ingredients together, and as an emulsion stabilizer, ensuring the consistency and integrity of creams and lotions. Additionally, it can be used to adjust product viscosity, enhancing the texture and user experience. Cosmetic formulators seeking to buy n-Docosanol can find it from suppliers who guarantee cosmetic-grade purity.

When sourcing n-Docosanol, particularly for industrial use, consider partnering with established manufacturers and suppliers, especially those in China, known for their robust chemical production capabilities. Key considerations include product purity, consistency of supply, competitive pricing, and adherence to quality certifications. It is always advisable to request samples and review Certificates of Analysis (CoA) to confirm that the material meets your specific application requirements. Understanding the supplier's production capacity, minimum order quantities, and delivery terms is also crucial for a smooth procurement process.

In summary, n-Docosanol is a valuable chemical with significant applications in both the pharmaceutical and cosmetic industries. Its antiviral properties make it a critical ingredient in certain medical treatments, while its emollient and stabilizing functions enhance cosmetic formulations. By diligently researching and partnering with reliable suppliers, businesses can ensure they obtain high-quality n-Docosanol to meet their diverse product development needs.
