PROPYLENE GLYCOL T-BUTYL ETHER

Description

Propylene Glycol t-Butyl Ether (PGTBE) is a versatile solvent and coupling agent widely used in skincare and cosmetic formulations. This clear, colorless liquid is prized for its excellent solvency properties and low odor profile. PGTBE functions as an effective penetration enhancer, facilitating the absorption of active ingredients into the skin. Its molecular structure allows it to dissolve both water-soluble and oil-soluble components, making it invaluable in creating stable emulsions and improving product texture.

In skincare applications, PGTBE helps to enhance the efficacy of various active ingredients, including antioxidants and peptides. It contributes to the smooth application of products and aids in the even distribution of actives across the skin's surface. PGTBE also exhibits mild humectant properties, helping to maintain skin hydration.

From a formulation perspective, PGTBE is compatible with a wide range of cosmetic ingredients and can improve the overall stability of products. Its low irritation potential makes it suitable for use in sensitive skin formulations. However, as with any ingredient, patch testing is recommended for individuals with known sensitivities.
