Clearly Define Application Scenarios and Pinpoint Core Needs
The first step in choosing amino silicone oil is to clearly define the application scenario. In the textile industry, for processing natural fibers such as cotton and linen, prioritize high-viscosity, low-amine-value products. These amino silicone oils form a uniform thin film on the fiber surface, balancing softness and wrinkle resistance while avoiding yellowing risks. For synthetic fibers such as polyester and nylon, focus on permeability and elastic recovery to ensure the fabric remains crisp after finishing. In personal care (such as shampoos and conditioners), prioritize hydrophilicity and mildness to avoid the greasy feeling caused by traditional silicone oil residue. Polyether-modified amino silicone oils can be chosen, as the hydrophilic groups in their molecules balance smoothness and freshness. In industrial applications (such as leather care and metal rust prevention), focus on film-forming properties and weather resistance to ensure protection even in extreme environments.

Focus on Performance Parameters and Match Process Requirements
Performance parameters are key criteria for selection. Viscosity directly affects usage and processing efficiency: low-viscosity products (such as 500-1000 cSt) have strong permeability and are suitable for impregnation processes; high-viscosity products (such as 5000-10000 cSt) have excellent film-forming properties and are suitable for spraying or coating processes. The amine value (amino content) determines softness and yellowing risk: low-amine-value (0.1-0.3 mmol/g) products have low yellowing potential and are suitable for light-colored fabrics; high-amine-value (0.5-1.0 mmol/g) products offer better softness but require the use of anti-yellowing agents. In addition, pay attention to emulsion stability (particle size distribution), pH value (neutral or weakly alkaline is milder), and environmental indicators (such as VOC content and biodegradability) to ensure compliance with industry regulations and sustainable development requirements.

Verify Supplier Capabilities and Ensure Stable Quality
The supplier's technical expertise and production capacity directly affect product stability. Prioritize companies with independent R&D capabilities, as they can customize modified products (such as quaternized or epoxy-modified products) according to customer needs and provide application technical support. At the same time, we examine the production scale and quality control system to ensure that the performance difference between batches is less than 5%, thus avoiding product quality problems caused by raw material fluctuations or process defects.
