Aminoethylaminopropyl dimethicone

Aminoethylaminopropyl dimethicone (CAS 71750-80-6), also supplied under the trade designation QF 7747, is an amino-functional silicone polymer used across personal care and industrial markets.

Its amine groups allow it to bond selectively to surfaces, particularly hair, fiber, and coatings substrates. This chemical structure delivers durable conditioning and surface modification effects across various applications.

In hair care, it deposits onto damaged or chemically treated hair to improve combability and reduce friction. It imparts a smooth, silky feel in both rinse-off and leave-on conditioner formulations.

Textile and fiber finishing operations use it to apply a soft, lubricating hand to fabrics. This improves processability during manufacturing and enhances the overall end-use performance of the material.

In coatings and adhesive systems, it functions as a surface modifier and wetting agent. These properties are essential for improving substrate adhesion and ensuring film uniformity during application.

Leather finishing formulations incorporate it to enhance surface feel and improve the durability of topcoat layers. It is typically supplied as a clear to pale yellow viscous liquid for easy handling.

It is available in technical grade for industrial textile and coatings applications. It is also offered in cosmetic-grade specifications suitable for high-end personal care formulation requirements.

Emulsion forms are also commercially available, broadening compatibility with water-based systems. This versatility makes it a staple component for manufacturers seeking reliable surface modification solutions.
