Isopentyldiol

Description

Isopentyldiol, also known as 3-methyl-1,3-butanediol, is a versatile synthetic ingredient gaining popularity in skincare formulations. This colorless, odorless liquid functions as a humectant and solvent, offering multiple benefits for skin health and product efficacy. Isopentyldiol's molecular structure allows it to attract and retain moisture, helping to hydrate the skin and improve its barrier function. Unlike some traditional humectants, it has a lighter feel on the skin, making it suitable for various product textures.

In formulations, Isopentyldiol enhances the solubility of active ingredients, potentially improving their penetration and effectiveness. It also exhibits antimicrobial properties, which can contribute to product preservation. Studies have shown that Isopentyldiol can boost the efficacy of other skincare ingredients, particularly in sun protection formulas, by improving the distribution of UV filters. Its low irritation potential makes it suitable for sensitive skin types.

Formulators appreciate Isopentyldiol for its stability across a wide pH range and compatibility with most cosmetic ingredients. It can be used in concentrations up to 5% in leave-on products and up to 10% in rinse-off formulations, offering flexibility in product development across various skincare categories.
