According to Guoli Chemical technical data, Refined Coconut Oil 6501-98% (Ninal) is recommended to be added in the later stage of formulation preparation, stirring evenly; the specific addition amount should be determined based on the target viscosity and formulation system. Compatibility verification should be conducted before use, and a single fixed addition ratio cannot be provided.
### Detailed Description
Refined Coconut Oil 6501-98% (Ninal) is a high-purity coconut oil diethanolamide, belonging to the classic non-ionic surfactant, with an active content of over 98%. In formulations, it mainly serves as an efficient co-surfactant, performing four major functions: **thickening, foam stabilization, emulsification, and detergency synergism**.
- **Usage Method**:
- **Feeding Stage**: Guoli Chemical technical data clearly states that it is recommended to be added **in the later stage of formulation preparation**. Usually, it is added after the main surfactants (such as AES, LAS, etc.) are completely dissolved and the pH value is adjusted, then stirred and mixed with 6501. This maximizes the synergistic thickening effect with anionic surfactants.
- **Feeding Operation**: The product may become viscous or paste-like at low temperatures, which does not affect product quality. Before use in winter, it can be slightly warmed in a water bath (below 40°C) to restore fluidity, then directly added. After addition, stir until completely uniform to avoid local high concentration forming gel clumps.
- **Recommended Addition Amount**:
Guoli Chemical technical data emphasizes that **the specific dosage needs to be determined based on the target viscosity and formulation system**. This is because the thickening and foam stabilization effects of 6501 are affected by various factors such as the type and content of main surfactants in the formulation, presence of electrolytes, and system pH. Different product systems have different requirements for viscosity and foam, so a fixed optimal dosage cannot be provided. The reference dosages below are based on extensive industry application practices; the final dosage must be determined through small-scale and pilot-scale tests.
### Application Recommendations
Based on the application fields in Guoli Chemical product database, combined with common industry practices, the following are reference addition amount ranges for different formulation systems for your trial reference:
| Application Field | Recommended Addition (wt%) | Usage Instructions/Expected Effect |
| :--- | :--- | :--- |
| **Personal Care Products** | **1.0% - 4.0%** | Thickening in products such as shampoos and body washes, making foam fine and rich, and reducing formulation irritation. |
| **Household Cleaners** | **1.0% - 5.0%** | Enhancing degreasing ability in dishwashing liquids and laundry detergents, and effectively thickening in low-active systems. |
| **Industrial & Institutional Cleaning Agents** | **2.0% - 6.0%** | Used in heavy-duty cleaning formulations, providing excellent emulsifying and dispersing capabilities, improving cling performance. |
| **Textile Printing & Dyeing Auxiliaries** | **2.0% - 5.0%** | As a component of scouring agents or detergents, removing impurities and unfixed dyes from fabrics, imparting a soft hand feel. |
| **Metalworking Fluids** | **1.0% - 3.0%** | As an emulsifier to stabilize oil-water mixed systems in cutting fluids and grinding fluids. |
**Note**: The reference addition amounts in the table above are compiled based on general industry knowledge and are not directly provided by Guoli Chemical technical data. **The optimal dosage needs to be determined through your small-scale and pilot-scale tests.**
### Precautions
- **Compatibility Verification**: Before use, be sure to conduct compatibility tests in your specific formulation system to confirm the thickening effect and the appearance stability of the finished product after long-term storage (whether turbidity, stratification, etc. occur).
- **Operational Safety**: This product is classified as a skin irritant (Category 2, H315) and a serious eye irritant (Category 2A, H319). **Protective gloves and safety goggles must be worn** during operation to avoid contact with skin and eyes. In case of accidental eye contact, rinse immediately with plenty of water for several minutes; if irritation persists, seek medical attention immediately.
- **Health & Environment**: This product is harmful to aquatic life with long-lasting effects (Category 3, H412). Waste liquid after operation must not be discharged directly into water bodies and should be disposed of in accordance with relevant hazardous waste regulations.
- **Storage Conditions**: Store in a cool, dry, well-ventilated place, recommended temperature not exceeding 40°C, avoiding freezing. Keep containers tightly closed, away from strong oxidizing agents and acids.
