Gluconolactones are cyclic esters derived from glucose, known for their mildness and excellent emulsifying properties in personal care applications. These compounds are widely used as thickening agents, emulsifiers, and humectants in skincare products due to their ability to enhance product stability and provide a smooth texture. They also serve as natural preservatives, reducing the need for synthetic additives. Additionally, gluconolactones contribute to skin hydration by retaining moisture, making them particularly suitable for formulations targeting dry or sensitive skin. Their pH buffering capacity ensures gentle cleansing without altering the skin’s natural acidity level, making these esters a preferred choice in formulating gentle yet effective skincare and personal care products.
