BUTYROLACTONE
Description
Butyrolactone, also known as γ-butyrolactone or GBL, is a versatile organic compound that has found applications in various industries, including skincare and cosmetics. This colorless, hygroscopic liquid is a lactone ester of 4-hydroxybutyric acid and possesses unique properties that make it valuable in formulations.
In skincare, butyrolactone functions primarily as a solvent and penetration enhancer. It helps to dissolve other ingredients effectively and can improve their absorption into the skin. This characteristic makes it particularly useful in formulations containing active ingredients that require efficient delivery to be effective.
Butyrolactone also exhibits moisturizing properties, helping to keep the skin hydrated and supple. Its ability to form hydrogen bonds with water molecules contributes to its humectant-like effects. Additionally, it can act as a preservative booster, enhancing the efficacy of other preservatives in the formulation and contributing to product stability.
When used in appropriate concentrations, butyrolactone is generally considered safe for topical application. However, formulators must be cautious with its usage due to its potential for conversion to gamma-hydroxybutyric acid (GHB) under certain conditions. Proper formulation and pH control are essential to ensure product safety and efficacy.
