CHLORHEXIDINE DIHYDROCHLORIDE

Description

Chlorhexidine dihydrochloride is a potent antiseptic and disinfectant widely used in medical and skincare applications. This synthetic compound belongs to the biguanide class of chemicals and is known for its broad-spectrum antimicrobial activity against bacteria, fungi, and some viruses. Its molecular structure allows it to bind to cell membranes, disrupting their integrity and leading to microbial cell death.

In skincare formulations, chlorhexidine dihydrochloride is typically used at concentrations between 0.1% to 4%, depending on the specific application. It is particularly effective in reducing skin flora and preventing infections in surgical sites, wounds, and burns. The ingredient exhibits residual antimicrobial activity on the skin, providing prolonged protection against pathogens.

Chlorhexidine dihydrochloride is water-soluble and compatible with many other skincare ingredients, making it versatile in various formulations. It is stable at a wide pH range (5-8) and resistant to heat, enhancing its shelf life and efficacy. However, it may cause skin irritation or allergic reactions in some individuals, particularly at higher concentrations. Its use is contraindicated on mucous membranes and in eye products due to potential toxicity.
