ALUMINUM SESQUICHLOROHYDREX PEG

Description

Aluminum Sesquichlorohydrex PEG is a complex aluminum salt compound widely used in antiperspirant formulations. This synthetic ingredient functions as an effective antiperspirant agent by forming temporary gel-like plugs in the sweat ducts, reducing perspiration on the skin's surface. The PEG (polyethylene glycol) component enhances its solubility and helps distribute the active compound more evenly across the skin.

The ingredient works by interacting with electrolytes in sweat to create small, gel-like precipitates that temporarily occlude sweat glands. This mechanism effectively reduces sweat production for extended periods, typically 24-48 hours. Aluminum Sesquichlorohydrex PEG is generally well-tolerated by most skin types and is less likely to cause irritation compared to some other aluminum-based antiperspirant compounds.

In formulations, it is often used at concentrations between 10-25%, depending on the desired strength of the antiperspirant effect. This ingredient complies with FDA regulations for over-the-counter antiperspirant active ingredients. While effective, it's important to note that some consumers prefer aluminum-free alternatives due to concerns about long-term aluminum exposure, although scientific consensus on potential risks remains inconclusive.
