BROMOETHYL PCA

Description

Bromoethyl PCA, also known as 2-Bromoethyl Pyrrolidone-5-Carboxylate, is a multifunctional cosmetic ingredient that serves as both a moisturizer and a preservative enhancer. This synthetic compound is derived from pyrrolidone carboxylic acid (PCA), a naturally occurring component of human skin. Bromoethyl PCA functions as a humectant, drawing moisture from the environment to hydrate the skin's upper layers. Its molecular structure allows it to penetrate the stratum corneum effectively, contributing to improved skin barrier function and moisture retention.

As a preservative enhancer, Bromoethyl PCA works synergistically with traditional preservatives to increase their efficacy, potentially allowing for lower concentrations of preservatives in formulations. This attribute is particularly valuable in developing gentler skincare products for sensitive skin types. Bromoethyl PCA exhibits antimicrobial properties, helping to protect cosmetic formulations against a broad spectrum of microorganisms.

In skincare products, Bromoethyl PCA is typically used at concentrations between 0.1% and 1%. It is compatible with a wide range of cosmetic ingredients and remains stable in various pH environments, making it versatile for use in creams, lotions, and serums. While generally well-tolerated, as with any skincare ingredient, patch testing is recommended for individuals with sensitive skin or known allergies.
