Used primarily as a hydrophobic monomer in the formulation of emulsion polymers and copolymers, it imparts water resistance and film-forming properties to coatings, adhesives, and cosmetics. Its long alkyl chain enhances compatibility with non-polar systems and improves the flexibility and durability of polymer films. Commonly found in personal care products such as lotions and creams, where it helps stabilize emulsions and provides a smooth, non-greasy feel. Also utilized in textile finishes and leather treatments to improve water repellency and surface texture.
