BUTYLENE GLYCOL

Description

Butylene glycol is a versatile and widely used ingredient in skincare and cosmetic formulations. This colorless, viscous liquid functions as a humectant, solvent, and conditioning agent. Its molecular structure allows it to penetrate the skin easily, making it an effective carrier for other active ingredients.

As a humectant, butylene glycol attracts and retains moisture, helping to keep the skin hydrated and plump. It also acts as a solvent, aiding in the dissolution of other ingredients and improving the overall stability of formulations. In addition, butylene glycol has mild antimicrobial properties, which can help preserve products and maintain their efficacy.

This ingredient is generally well-tolerated by most skin types and is considered safe for use in cosmetics at typical concentrations. It can be found in a wide range of products, including moisturizers, serums, toners, and makeup. Butylene glycol's ability to enhance the texture of formulations and improve the spreadability of products contributes to its popularity among formulators.

While some individuals may have concerns about its synthetic nature, butylene glycol has a long history of safe use in skincare and is approved by regulatory bodies worldwide.
