Hydroxyethylpiperazine Ethane Sulfonic Acid, commonly known as HEPES, is a synthetic organic compound used in cosmetics primarily as a buffering agent. It helps to stabilize the pH of a product, ensuring that other active ingredients remain effective and the formula is gentle on the skin. This stability is crucial for maintaining product integrity and performance over time.
