Amino silicone oils are a class of organofunctional silicone fluids in which amino groups (–NH₂, –NH–, or aminoalkyl groups) are chemically grafted onto a polydimethylsiloxane (PDMS) backbone. This structural modification gives the silicone oil cationic or polar character, fundamentally changing its surface interaction behavior compared with conventional dimethyl silicone oils. Amino silicone oils combine the lubricity and flexibility of silicone with the strong surface affinity of amine chemistry.
SiliconChemicals® Amino Silicone Oils are high-performance organofunctional silicone fluids engineered with amino (–NH₂ / –NH–) functional groups grafted onto a polydimethylsiloxane (PDMS) backbone. They are specifically designed to deliver exceptional softness, durable conditioning, and strong surface affinity across textiles, personal care, leather, and industrial formulations.

SiliconChemicals® Amino Silicone Oils combine silicone lubricity with amine-driven surface affinity, offering precisely controlled softness, durability, and conditioning performance for textiles, personal care, and industrial applications.
SiliconChemicals® Amino Silicone Oils are high-performance organofunctional silicone fluids engineered with amino (–NH₂ / –NH–) groups grafted onto a polydimethylsiloxane (PDMS) backbone.
They are designed to deliver exceptional softness, durable conditioning, and strong surface affinity, far exceeding the performance of conventional dimethyl silicone oils.
SiliconChemicals® Amino Silicone Oils combine silicone lubricity with amine-driven surface affinity to deliver long-lasting softness, conditioning, and performance across textile, personal care, and industrial applications.
Understanding chemical structure is essential to understanding why Amino Silicone Oils work.
At SiliconChemicals®, Amino Silicone Oils are engineered by introducing amino-functional groups into a silicone (PDMS) molecular framework, creating a material that combines silicone lubricity with amine-driven surface affinity.
The backbone of Amino Silicone Oil is polydimethylsiloxane (PDMS):
PDMS alone provides slip and lubrication, but has very weak adhesion to most substrates.
In Amino Silicone Oils, part of the methyl groups (–CH₃) on the PDMS chain are replaced by amino-functional side chains, typically:
These amino groups are chemically bonded to the silicone chain, not physically blended.
A simplified representation:
–[Si–O]n– backbone | –(CH2)x–NH2 / NH / NR3+
Key structural variables include:
Each variable directly influences performance.
Most application substrates—such as textile fibers, hair keratin, leather collagen, and polymer surfaces—carry negative surface charges.
Result:
Much higher substantivity and durability compared with non-functional silicone oils.
Once adsorbed, the PDMS backbone:
Result:
Amino Silicone Oils operate primarily under boundary lubrication conditions:
Result:
Long-lasting softness, improved wear resistance, and reduced squeaking or static buildup.
For tertiary and quaternary amino silicone oils:
Result:
Effective antistatic performance, especially on synthetic fibers such as polyester and nylon.
| Structural Element | Functional Impact |
|---|---|
| Higher amino content | Stronger adsorption, higher softness, higher yellowing risk |
| Secondary / blocked amines | Lower yellowing, better stability |
| Higher molecular weight | Richer, fuller hand feel, better durability |
| Hydroxy-terminated chains | Reactivity, crosslinking, improved wash resistance |
| Quaternary ammonium groups | Permanent cationic, strong antistatic effect |
| Aspect | Dimethyl Silicone Oil | Amino Silicone Oil |
|---|---|---|
| Surface adhesion | Very low | Very high |
| Durability | Limited | Excellent |
| Conditioning effect | Moderate | Strong |
| Wash-off resistance | Poor | Good to excellent |
| Antistatic ability | Minimal | Effective |

Key benefits
SiliconChemicals® Amino Silicone Oils are versatile conditioning silicones used across textiles, personal care, leather, and industrial applications to deliver long-lasting softness, smoothness, antistatic performance, and superior surface feel.
Amino Silicone Oil is chosen when standard silicone oils are no longer sufficient. By chemically integrating amino functional groups into a flexible PDMS backbone, Amino Silicone Oils deliver a unique combination of durable softness, strong surface affinity, and functional performance that conventional silicones cannot achieve.
Why it matters:
Softness is not just a surface effect—Amino Silicone Oils form a flexible silicone film that moves naturally with fibers and surfaces.
Why it matters:
Performance is durable, not temporary or cosmetic.
Why it matters:
Less friction means less damage, better feel, and longer service life.
Why it matters:
Static buildup affects comfort, processing efficiency, and appearance.
Amino Silicone Oils perform consistently across:
Why it matters:
One material platform supports multiple industries and formulations.
Why it matters:
Easy integration into existing manufacturing processes.
| Performance Aspect | Conventional Silicone Oil | Amino Silicone Oil |
|---|---|---|
| Softness | Good | Excellent |
| Surface adhesion | Low | Very high |
| Durability | Limited | Long-lasting |
| Conditioning effect | Moderate | Strong |
| Antistatic behavior | Minimal | Effective |
Amino Silicone Oil is used because it delivers durable softness, superior conditioning, and strong surface adhesion—combining the inherent advantages of silicone chemistry with the functional power of amino groups.
Selecting the correct Amino Silicone Oil is a performance-engineering decision, not a simple viscosity choice. The optimal grade depends on substrate, required hand feel, durability expectations, color sensitivity, and processing method. Below is a practical, step-by-step selection framework used by formulators and finishing engineers.
Different substrates interact with amino silicones in different ways.
| Substrate | Recommended Amine Type | Reason |
|---|---|---|
| Cotton / Viscose | Primary or Secondary | Strong adsorption and softness |
| Polyester / Nylon | Secondary or Quaternary | Controlled yellowing, antistatic |
| Wool / Silk | Secondary or Tertiary | Mild conditioning, fiber protection |
| Human hair | Tertiary | Low irritation, formulation stability |
| Leather / PU / PVC | Primary or Secondary | Softness and surface lubrication |
| Sensory Requirement | Recommended Molecular Weight |
|---|---|
| Light, silky touch | Low MW |
| Balanced softness | Medium MW |
| Rich, full, luxury feel | High MW |
| Maximum durability & fullness | Ultra-high MW |
Rule of thumb:
Higher molecular weight = richer feel + better durability, but higher formulation complexity.
For white or pastel materials:
| Color Sensitivity | Recommended Structure |
|---|---|
| Low (dark fabrics) | Primary amine |
| Medium | Secondary amine |
| High (white / light colors) | Blocked amine or secondary |
| Durability Requirement | Structural Choice |
|---|---|
| Standard softness | Capped (non-reactive) |
| Enhanced wash resistance | Hydroxy-terminated (–OH) |
| Permanent effect | Reactive or crosslinkable systems |
Hydroxy-terminated amino silicones can chemically anchor into finishing systems for long-term performance.
| Processing Method | Recommended Delivery Form |
|---|---|
| Padding / dipping | O/W emulsion |
| Spray application | Microemulsion |
| Concentrate blending | Neat fluid |
| Simplified processing | Self-emulsifying grade |
| Antistatic finishing | Cationic emulsion |
Choose a form that integrates seamlessly into your existing process.
| Requirement | Best Choice |
|---|---|
| Maximum softness | Primary, high MW |
| White fabric finishing | Secondary or blocked amine |
| Hair care formulations | Tertiary, low–medium MW |
| Antistatic effect | Quaternary amino |
| Long wash durability | Hydroxy-terminated |
