solvent and humectant used in cosmetics for moisture retention
Butylene glycol, also known as 1,3-butanediol, is a type of alcohol commonly used in cosmetics and skincare products. It acts as a solvent, helping to dissolve other ingredients, and as a humectant, which means it helps to retain moisture in the skin and hair. This makes it a valuable ingredient in formulations aimed at improving hydration and texture.
