Butylene Glycol

Description

Butylene Glycol is a versatile organic compound widely used in skincare and cosmetic formulations. This colorless, viscous liquid functions as a humectant, solvent, and conditioning agent. Its molecular structure allows it to attract and retain moisture, making it an effective hydrating ingredient for various skin types.

In skincare products, Butylene Glycol serves multiple purposes. It acts as a penetration enhancer, facilitating the delivery of other active ingredients deeper into the skin layers. This property improves the overall efficacy of formulations containing beneficial compounds such as antioxidants or peptides. Additionally, it contributes to the smooth texture and spreadability of creams, serums, and lotions.

Butylene Glycol also exhibits antimicrobial properties, helping to preserve product integrity and extend shelf life. Its low molecular weight allows for quick absorption without leaving a greasy residue, making it suitable for both oily and dry skin types. While generally well-tolerated, some individuals with sensitive skin may experience mild irritation.

This ingredient is commonly found in a wide range of skincare products, including moisturizers, toners, and masks, typically at concentrations between 1% and 5%. Its multifunctional nature and compatibility with various formulations make Butylene Glycol a valuable component in modern skincare.
