From high-end suits to baby clothes, from luxurious fur to daily shampoo, a material called "amino siloxane" is quietly transforming the tactile experience of countless products. What is its magic?
The essence of amino siloxane is a specially modified organic silicone emulsion. Its core structure consists of a flexible silicon-oxygen backbone and an active amino side chain. The silicon-oxygen backbone gives it extremely low surface tension and excellent resilience, while the amino group acts like "anchors", capable of strong physical adsorption or even chemical bonding with the hydroxyl, carboxyl, or hair keratin groups in the fibers. This "directional adsorption" mechanism makes amino siloxane less prone to loss like ordinary oils, but instead firmly adheres to the surface of the material, bringing a lasting smoothness.
In addition to its softness, amino siloxane also has multiple functions. It can effectively suppress the generation of static electricity and prevent dust adsorption; in leather processing, it can keep the leather breathable while increasing its luster; in paints and car waxes, it can act as a brightener to enhance weather resistance. Notably, amino siloxane is usually used in a microemulsion form, with extremely small particle sizes, which can penetrate into the fibers rather than just floating on the surface. Therefore, it provides a more plump and natural touch.
As environmental protection requirements increase, modern amino siloxane is developing towards higher stability and lower yellowing risks. This "smooth master hidden in life" is using technological power to continuously upgrade the tactile experience.
