The multiple hydroxyl groups on the GdL molecule attract water, resulting in a moisturizing effect when added to skin care formulations. Given their ability to condition and hydrate skin, GdL-containing formulations may even smooth skin texture and reduce the appearance of fine lines and wrinkles.\u003c\/span\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eGlucono Delta Lactone\u003c\/strong\u003e, often abbreviated as GdL, when added into an aqueous solution, rapidly dissolves, and slowly hydrolyzes to gluconic acid, thus producing a gentle acidification in the same way as lactic acid-producing bacteria. \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eGlucono Delta Lactone\u003c\/strong\u003e, through its slow hydrolysis to gluconic acid, ensures a progressive and continuous decrease of pH to equilibrium.  So it is used as a slow release acidifier in formulations.
