NONADECANE

Description

Nonadecane is a long-chain alkane hydrocarbon with the molecular formula C19H40. This colorless, odorless compound is a solid at room temperature and exhibits hydrophobic properties. In skincare and haircare formulations, nonadecane functions primarily as an emollient and conditioning agent.

As an emollient, nonadecane forms a protective barrier on the skin and hair, helping to reduce moisture loss and improve texture. Its lightweight nature allows for easy spreading and quick absorption, making it suitable for various product types. In haircare, nonadecane can enhance shine and manageability without leaving a greasy residue.

The compound's stability and resistance to oxidation contribute to its role as a preservative booster in cosmetic formulations. Nonadecane also acts as a thickening agent, helping to improve product consistency and texture. Its low comedogenicity makes it suitable for use in facial products, including those designed for acne-prone skin.

When incorporating nonadecane into formulations, it is typically used in concentrations ranging from 0.5% to 5%, depending on the desired effect and product type. Its compatibility with a wide range of cosmetic ingredients makes it a versatile choice for formulators seeking to enhance product performance and sensory attributes.
