Undecoylium chloride

Undecoylium chloride

Undecoylium chloride is a quaternary ammonium compound used as an antiseptic and disinfectant. It is a colorless, crystalline substance soluble in water and alcohol. It is used in many pharmaceutical and cosmetic products due to its antimicrobial properties.

Chemical Structure

Undecoylium chloride is a quaternary ammonium compound, which means it has a central nitrogen atom surrounded by four organic groups and one chloride ion. The organic groups are typically alkyl or aryl groups. In the case of undecoylium chloride, the organic groups are undecyl groups, which are chains of 11 carbon atoms.

Uses

Undecoylium chloride is primarily used as an antiseptic and disinfectant. It is found in many pharmaceutical products, including mouthwashes, throat sprays, and wound cleansers. It is also used in cosmetics as a preservative and to prevent the growth of bacteria and fungi.

Mechanism of Action

As a quaternary ammonium compound, undecoylium chloride works by disrupting the cell membranes of bacteria and fungi. This causes the cells to leak their contents and eventually die. The compound is effective against a wide range of microorganisms, including Gram-positive bacteria, Gram-negative bacteria, and yeasts.

Safety

Undecoylium chloride is generally considered safe for use in pharmaceutical and cosmetic products. However, it can cause skin irritation in some people, especially with prolonged or repeated exposure. It is also toxic if ingested or inhaled in large amounts.
