An amine-modified siloxane that anchors to fiber surfaces to deliver durable softness and smoothness. The pendant amine groups give it strong substantivity to fibers, making it a softening and conditioning agent for textile finishing.
▸Textile softening: Imparts a soft, smooth hand to fabrics.
▸Fiber finishing: Improves surface lubricity of fibers.
▸Softener emulsions: Base polymer for textile softener emulsions.

Frequently Asked Questions
What is amino functional silicone fluid?
Amino-functional silicone (CAS 71750-80-6) is an amino-modified polydimethylsiloxane carrying pendant amine groups. Those amine sites give it strong substantivity to fibers, making it a softening and conditioning fluid for textile finishing.
What is amino silicone used for?
It is used chiefly as a textile softener and fiber-finishing agent, imparting a soft, smooth hand and improved surface lubricity to fabrics. It also serves as the base polymer for textile softener emulsions.
Why does amino silicone bond so well to fibers?
The pendant amino groups interact strongly with fiber surfaces, giving high substantivity and durable deposition compared with non-functional silicone fluids. This is what drives its conditioning and lubricity performance in textile finishing.
Is amino functional silicone water soluble?
No. Like other PDMS-based silicone fluids it is not water soluble; it is typically applied as an emulsion in textile finishing systems. Request the spec sheet for viscosity and amine number details.
What packaging and HS code apply to amino functional silicone?
It classifies under HS 3910.00 (silicones in primary forms). RawSource supplies it in bulk drums and totes; specify viscosity and amine functionality for a bulk quote with CoA and SDS.
