ISOPENTYLDIOL

Description

Isopentyldiol is a versatile and multifunctional ingredient gaining popularity in skincare formulations. This colorless, odorless liquid is a dihydric alcohol that functions as a humectant, solvent, and emollient. Its molecular structure allows it to effectively penetrate the skin, enhancing the delivery of other active ingredients.

As a humectant, isopentyldiol attracts and retains moisture, helping to hydrate the skin and improve its overall appearance. It has been shown to outperform traditional humectants like glycerin in some applications. The ingredient's solvent properties make it an excellent carrier for both oil and water-soluble actives, improving their solubility and stability in formulations.

Isopentyldiol also exhibits antimicrobial properties, potentially contributing to product preservation. Its low molecular weight enables it to enhance the skin's barrier function by reducing transepidermal water loss. Additionally, it can help improve the texture and spreadability of skincare products, creating a smooth, non-tacky feel on the skin.

This ingredient is generally well-tolerated and suitable for various skin types, making it a valuable addition to moisturizers, serums, and other skincare products seeking to improve hydration, texture, and overall efficacy.
