HEXAMIDINE DIISETHIONATE

Description

Hexamidine diisethionate is a potent antimicrobial agent widely used in skincare and cosmetic formulations. This synthetic compound belongs to the class of aromatic diamidines and exhibits broad-spectrum activity against bacteria, fungi, and certain protozoa. Its primary function is as a preservative, extending the shelf life of products by inhibiting microbial growth.

The ingredient's molecular structure allows it to penetrate cell membranes, disrupting microbial metabolism and leading to cell death. Hexamidine diisethionate is particularly effective against gram-positive bacteria and shows significant efficacy against Propionibacterium acnes, a key contributor to acne vulgaris. Its antifungal properties make it valuable in combating conditions like seborrheic dermatitis and dandruff.

In skincare formulations, hexamidine diisethionate is typically used at concentrations between 0.1% and 0.3%. It is compatible with a wide range of cosmetic ingredients and remains stable across various pH levels. While generally well-tolerated, some individuals may experience skin sensitization with prolonged use. As with any preservative, patch testing is recommended before incorporating products containing hexamidine diisethionate into a skincare regimen, especially for those with sensitive skin or a history of allergic reactions.
