Ceryl alcohol, also known as 1-hexacosanol, is a long-chain fatty alcohol with the chemical formula C₂₆H₅₄O. It is a white, waxy solid at room temperature and is primarily used in the cosmetic and pharmaceutical industries.

Structure and Properties

Ceryl alcohol is a saturated fatty alcohol with a 26-carbon chain. It is part of the aliphatic alcohol family and is characterized by its long hydrocarbon chain and a terminal hydroxyl group. This structure gives it hydrophobic properties, making it insoluble in water but soluble in organic solvents.

The melting point of ceryl alcohol is approximately 49 to 50 °C, and it has a boiling point of about 404 °C. These properties make it suitable for use in formulations that require stability at higher temperatures.

Sources and Production

Ceryl alcohol is naturally found in beeswax and spermaceti, a waxy substance obtained from the sperm whale. It can also be synthesized through the reduction of cerotic acid, a fatty acid found in waxes and oils.

Applications

Ceryl alcohol is widely used in the cosmetic industry as an emollient, thickener, and emulsifier. It is commonly found in products such as lotions, creams, and conditioners. Its ability to form stable emulsions makes it valuable in creating smooth and consistent textures in topical formulations.

In the pharmaceutical industry, ceryl alcohol is used as an excipient in the formulation of ointments and creams. It helps to stabilize the active ingredients and improve the texture and application of the product.

Safety and Environmental Impact

Ceryl alcohol is generally considered safe for use in cosmetics and pharmaceuticals. It is non-toxic and non-irritating to the skin. However, as with all chemical substances, it should be handled with care to avoid unnecessary exposure.

From an environmental perspective, ceryl alcohol is biodegradable and does not pose significant risks to aquatic life. Its use in products is regulated to ensure safety for both consumers and the environment.
