Undecane

Description

Undecane is a straight-chain hydrocarbon compound with the molecular formula C11H24. This colorless, odorless liquid belongs to the alkane family and is naturally found in small quantities in petroleum and some essential oils. In skincare formulations, undecane serves multiple purposes, primarily as an emollient and solvent.

As an emollient, undecane helps to soften and smooth the skin by forming a thin, non-greasy film on the surface. This property makes it particularly useful in lightweight, fast-absorbing formulations. Undecane's low viscosity and spreadability contribute to improved texture and application of skincare products.

In its role as a solvent, undecane aids in dissolving and dispersing other ingredients, enhancing the overall stability and effectiveness of formulations. Its volatile nature allows for quick evaporation, leaving minimal residue on the skin. This characteristic is beneficial in products designed for oily or acne-prone skin types.

Undecane is generally considered safe for topical use and is well-tolerated by most skin types. However, as with any ingredient, patch testing is recommended to ensure individual compatibility. Its inclusion in skincare products often contributes to improved texture, enhanced penetration of active ingredients, and a pleasant, non-greasy skin feel.
