UNDECYLENAMIDOPROPYLTRIMONIUM METHOSULFATE
Description
Undecylenamidopropyltrimonium methosulfate is a quaternary ammonium compound with multifunctional properties in skincare and haircare formulations. This cationic surfactant serves primarily as a conditioning agent and emulsifier. Its molecular structure consists of a long-chain fatty acid (undecylenic acid) linked to a positively charged nitrogen atom, providing both hydrophobic and hydrophilic components.
In skincare products, undecylenamidopropyltrimonium methosulfate acts as an effective emollient, enhancing the skin's softness and smoothness. It also exhibits mild antistatic properties, reducing surface tension and improving the spread of formulations. The ingredient's cationic nature allows it to adhere to negatively charged skin and hair surfaces, facilitating the deposition of other beneficial ingredients.
Notably, undecylenamidopropyltrimonium methosulfate demonstrates antimicrobial activity, potentially contributing to product preservation and skin health. Its compatibility with various cosmetic ingredients makes it versatile in formulations ranging from leave-on creams to rinse-off cleansers. While generally well-tolerated, individuals with sensitive skin should perform patch tests before widespread use. The concentration of this ingredient in cosmetic formulations typically ranges from 0.1% to 5%, depending on the desired effect and product type.
