butylene glycol

Description

Butylene glycol is a versatile and widely used ingredient in skincare and cosmetic formulations. This colorless, viscous liquid is a member of the glycol family and functions primarily as a humectant and solvent. Its molecular structure allows it to attract and retain moisture, making it an effective hydrating agent for the skin. Butylene glycol also enhances the penetration of other active ingredients, improving their efficacy.

In skincare products, butylene glycol serves multiple purposes. It acts as a texture enhancer, contributing to a smooth, silky feel. Its solvent properties aid in dissolving and dispersing other ingredients, ensuring uniform product consistency. Additionally, it functions as a preservative booster, helping to maintain product stability and extend shelf life.

Butylene glycol is generally well-tolerated by most skin types and is considered safe for use in cosmetics at typical concentrations. It's particularly beneficial in formulations targeting dry or dehydrated skin. While some individuals with sensitive skin may experience mild irritation, adverse reactions are rare. This ingredient is found in a wide range of products, including moisturizers, serums, toners, and makeup, due to its multifunctional nature and compatibility with various formulation types.
