Aminopropyl Dimethicone

Aminopropyl Dimethicone (CAS 99363-37-8) is an amine-functional silicone polymer.

Where is Aminopropyl Dimethicone used?

• Hair care: deposits onto damaged or chemically treated fiber, delivering lasting smoothness and reducing combing force without heavy buildup
• Textile finishing: softening and surface-modification agent on synthetic and natural fabrics
• Coatings and adhesives: reactive amine groups serve as crosslinking sites
• Leather treatment: conditions and protects finished surfaces while maintaining flexibility and surface uniformity
• The amine groups along the silicone backbone allow it to bond to surfaces and substrates that standard silicones cannot.

Good to know: The amine functionality improves adhesion to difficult substrates including glass, metal, and plastics. Technical grades suit environments where cosmetic purity thresholds are not required.
