ALUMINUM PCA

Description

Aluminum PCA, or Aluminum Polyhydroxycomplexes, is a synthetic compound widely used in skincare and personal care products for its antiperspirant and deodorant properties. This ingredient is formed by the reaction of aluminum chloride with pyrrolidone carboxylic acid (PCA), resulting in a stable, water-soluble complex.

The primary function of Aluminum PCA is to reduce sweat production by temporarily blocking sweat glands. It forms a gel-like plug in the sweat ducts, effectively reducing perspiration in the applied area. This mechanism makes it a key component in many antiperspirant formulations.

In addition to its antiperspirant effects, Aluminum PCA exhibits mild antimicrobial properties, helping to control odor-causing bacteria on the skin. It is generally well-tolerated and considered safe for use in cosmetic products at regulated concentrations.

Aluminum PCA is typically incorporated into roll-ons, sticks, and spray antiperspirants. Its efficacy and stability in various formulations have made it a popular choice among manufacturers. While effective, it's important to note that some individuals may be sensitive to aluminum-based compounds, and alternatives are available for those seeking aluminum-free options.
