Isopentyldiol 100 g

Isopentyldiol water soluble diol solvent and sensory modifier for cosmetic formulations

Isopentyldiol is a water soluble organic diol widely used in cosmetic formulations as a solvent and distribution medium for active ingredients. The material appears as a clear colorless liquid with low viscosity and almost neutral odor. The ingredient is fully soluble in water and compatible with glycerin, propanediol and butylene glycol. Due to its molecular structure the component improves the distribution of ingredients within aqueous and gel systems and contributes to formulation stability.

Properties and skin feel

In cosmetic formulations Isopentyldiol provides a light transparent texture and smooth spreading properties. In gels and serums it supports clear structure and balanced sensory performance.

Industry applications

Isopentyldiol is used in facial serums, creams, lotions, toners, cleansing products and hair care formulations. The ingredient is also used in SPA products and functional cosmetic systems where uniform distribution of ingredients is required. Due to broad compatibility with cosmetic bases it is widely applied in private label development and contract manufacturing.

Formula example Transparent hydrating facial gel

Isopentyldiol 68 g
Glycerin 55 g
Cucumber extract 45 g
Panthenol 30 g
Xanthan gum 8 g
Purified water 580 ml
Sodium citrate 6 g

Xanthan gum is dispersed in purified water until a clear gel base forms. Glycerin and Isopentyldiol are incorporated with continuous mixing until a uniform structure is obtained. Panthenol and cucumber extract are then blended into the formulation ensuring even distribution. The pH of the aqueous system is adjusted using sodium citrate until a stable gel texture is achieved. The final result is a transparent hydrating facial gel with light sensory feel.

Isopentyldiol is designed for B2B cosmetic manufacturers, formulation laboratories and contract production facilities. The ingredient provides stable formulation behavior, reproducible sensory characteristics and compatibility with scalable industrial manufacturing.
