Ethyl silicone oil is a lightweight, moderately volatile silicone fluid with low surface tension, increasingly used in the surface treatment of flexible materials like textiles, paper, and plastic films.

It spreads easily and forms a smooth, transparent film that reduces friction and enhances softness. It is ideal for soft-touch fabrics, anti-block packaging films, and leather treatments, offering added benefits like water repellency, stain resistance, and anti-fingerprint effects—without affecting breathability or appearance.

Compared to traditional silicone oils, ethyl silicone oil is more biodegradable and eco-friendly, attracting attention from green chemistry developers. Combined with fluorosilicones or polyether-modified silicones, it enables next-generation surface treatments with enhanced functionality and compatibility.
