UNDECANE

Description

Undecane is a linear hydrocarbon compound belonging to the alkane family, with the chemical formula C11H24. This colorless, odorless liquid is naturally found in small quantities in various plant and animal sources. In skincare formulations, undecane serves as an emollient and solvent, providing multiple benefits to cosmetic products.

As an emollient, undecane helps to soften and smooth the skin's surface, creating a silky texture and improving overall skin feel. Its lightweight nature allows for quick absorption without leaving a greasy residue. Undecane also functions as an effective solvent, aiding in the dissolution and dispersion of other active ingredients within formulations.

The compound's low volatility contributes to its stability in skincare products, ensuring consistent performance over time. Undecane's non-polar structure makes it compatible with a wide range of cosmetic ingredients, enhancing formula versatility. Additionally, its ability to form a thin, breathable film on the skin's surface helps to reduce transepidermal water loss, promoting hydration and maintaining skin barrier function.

While generally well-tolerated, undecane may cause mild irritation in sensitive individuals. As with any skincare ingredient, patch testing is recommended before widespread use.
