Introduction to Polyethylene Glycol Monocetyl Ether (CAS 9004-95-9)
Polyethylene Glycol Monocetyl Ether, also known as cetomacrogol, is a non-ionic surfactant with the chemical formula C24H48O4. It is a derivative of polyethylene glycol, which is a polymer of ethylene oxide. This compound is characterized by its hydrophilic and lipophilic properties, making it suitable for a wide range of applications. In this article, we will delve into the various aspects of Polyethylene Glycol Monocetyl Ether, including its chemical structure, synthesis, and uses.
Chemical Structure and Synthesis
The chemical structure of Polyethylene Glycol Monocetyl Ether consists of a polyethylene glycol backbone with a single cetyl group attached to one end. This structure allows the compound to act as a bridge between water-soluble and oil-soluble substances. The synthesis of cetomacrogol typically involves the reaction of ethylene oxide with a fatty alcohol, such as cetanol, in the presence of a catalyst. This process results in the formation of a polyoxyethylated fatty alcohol, which is then purified to obtain the desired product.
Applications of Polyethylene Glycol Monocetyl Ether
Polyethylene Glycol Monocetyl Ether finds extensive use in various industries due to its unique properties. One of the primary applications is in the pharmaceutical industry, where it is used as an emulsifier and solubilizer in oral and topical formulations. It is also employed in the cosmetic industry as a skin conditioning agent and emulsifier in creams, lotions, and shampoos. Additionally, cetomacrogol is used in the food industry as a stabilizer and emulsifier in food products, such as ice cream and salad dressings.
Safety Considerations
When it comes to safety, Polyethylene Glycol Monocetyl Ether is considered to be relatively safe for human use. It is classified as a non-toxic compound, and its acute oral toxicity is low. However, as with any chemical, it is important to handle it with care and follow proper safety protocols. Ingestion of large amounts of cetomacrogol can cause gastrointestinal irritation, while skin contact may lead to mild irritation. It is also important to note that the compound is not recommended for use in eye drops or other ophthalmic preparations due to potential irritation.
Environmental Impact
The environmental impact of Polyethylene Glycol Monocetyl Ether is a topic of concern. While the compound is biodegradable, its breakdown products can still be harmful to aquatic life. Therefore, it is crucial to minimize the release of cetomacrogol into the environment. Proper waste management and the use of biodegradable alternatives are essential to mitigate the potential ecological impact.
Regulatory Status
Polyethylene Glycol Monocetyl Ether is regulated by various agencies around the world. In the United States, the Food and Drug Administration (FDA) has approved its use in food, drugs, and cosmetics. Similarly, the European Union has established guidelines for its use in these industries. It is important for manufacturers and users to stay informed about the regulatory status of cetomacrogol to ensure compliance with applicable laws and regulations.
Conclusion
Polyethylene Glycol Monocetyl Ether (CAS 9004-95-9) is a versatile compound with a wide range of applications. Its unique chemical structure and properties make it an essential ingredient in various industries, including pharmaceuticals, cosmetics, and food. While the compound is considered safe for human use, it is important to handle it with care and minimize its environmental impact. By understanding the various aspects of cetomacrogol, we can appreciate its significance in modern society and ensure its responsible use.
