PRODUCT DESCRIPTION

Isopentyldiol is a multifunctional diol used in modern cosmetic and skincare formulations as a humectant, solvent and skin-conditioning ingredient.

It helps attract and retain moisture, supporting hydrated, soft and comfortable-feeling skin. Its moisturizing properties make it particularly suitable for facial serums, creams, lotions, moisturizers and other hydration-focused skincare products.

Isopentyldiol also functions as a useful cosmetic solvent, helping dissolve or incorporate suitable active ingredients and other formulation components. This makes it valuable in formulations containing multiple functional ingredients where efficient incorporation and uniform distribution are important.

As a sensory modifier, Isopentyldiol can contribute to a pleasant and elegant formulation feel, making it particularly attractive for modern facial-care and premium skincare products.

Its combination of humectancy, solvent performance, skin conditioning and sensory enhancement allows formulators to obtain several functional benefits from a single ingredient.

Isopentyldiol is therefore an excellent choice for advanced moisturizing serums, facial creams, lotions, eye-care products, hydrating gels and other professional skincare formulations.
