Used as a pH buffer in cosmetic formulations to maintain product stability and skin compatibility. Commonly found in creams and lotions where it helps regulate acidity and prevent irritation. Also serves as a mild chelating agent, enhancing the effectiveness of preservatives by binding metal ions that could degrade the product over time. Its low volatility and high water solubility make it suitable for use in aqueous systems and spray products. Frequently chosen in eco-friendly and dermatological products due to its low toxicity and biodegradability.
