According to Guoli Chemical technical data, the core advantage of Guoli Chemical’s Cocamide DEA/CDEA 6501-92% (Ninol) lies in its **highly active content of 92%**, which gives it significant advantages in thickening efficiency, foam stability, and overall cost-effectiveness compared to common 6501 products on the market (typically with active content between 70% and 85%).
### Detailed Description
This product is a high-purity nonionic surfactant made from high-quality coconut oil through condensation with diethanolamine. The "92% high content" means more concentrated active ingredients and fewer impurities, allowing it to achieve equivalent or better performance at lower addition levels in formulations.
Compared to similar products with lower active content, it excels in the following aspects:
1. **Thickening Performance**: Thickening efficiency far exceeds conventional products. In formulations containing inorganic salts (e.g., sodium chloride), it can more efficiently build the desired viscosity, reducing the total amount of thickener needed and lowering costs.
2. **Foam Performance**: When combined with anionic surfactants (e.g., AES, LAS), it not only significantly enhances foamability but, more importantly, produces fine, long-lasting foam, greatly improving the user experience in high-end personal care products.
3. **Compatibility and Application**: High purity means fewer free amines and impurities, offering excellent compatibility with anionic, cationic, and amphoteric surfactants. It has stronger formulation adaptability and is less prone to side reactions.
### Specific Data Comparison
The following is a simulated performance comparison between Guoli Chemical’s 92% specification product and a conventional 70% specification product in a typical liquid detergent formulation, based on common industry experience:
| Performance Indicator | Guoli Chemical Cocamide DEA 6501 (92%) | Conventional Similar Product (70%) | Advantage Description |
| :--- | :--- | :--- | :--- |
| **Active Content** | **≥ 92%** | 70% ~ 80% | Higher effective ingredients, lower impurities |
| **Recommended Thickener Dosage** | 0.5% - 2.0% | 1.5% - 4.0% | **More than 50% dosage saving** to achieve same viscosity |
| **Thickening Efficiency (viscosity at equal dosage)** | **High** | Medium-Low | Faster thickening response, higher peak viscosity |
| **Foam Height and Stability** | **Excellent** | Good | Richer foam, longer foam stability, better feel |
| **Residual Free Amine** | **Low** | Relatively high | Less odor, lower irritation, higher safety |
| **Appearance** | Clear viscous liquid from light yellow to amber | May be darker in color, batch-to-batch variation possible | More transparent appearance, beneficial for light-colored products |
### Application Recommendations
Based on its high efficiency in thickening and foam stabilization, it is especially recommended for the following high-end formulations:
- **Concentrated Products**: Such as ultra-concentrated laundry detergents and dishwashing liquids, can significantly reduce thickener dosage while keeping the formula clear.
- **High-End Personal Care**: Such as amino acid shampoos and mild facial cleansers, achieving ideal consistency and dense foam with low addition levels.
- **Industrial Cleaning Formulations**: In degreasers and metal cleaners requiring high alkali resistance, as an efficient emulsifying and thickening component to improve cleaning performance.
### Precautions
- **Addition Method**: It is recommended to add at a system temperature of 40-60°C and stir thoroughly to facilitate quick dispersion and effectiveness.
- **Viscosity Adjustment**: Its thickening effect depends on the salt concentration in the formulation. Determine the optimal salt dosage through small-scale trials to avoid overdosage leading to viscosity drop or turbidity.
- **Safe Handling**: Although this product has relatively low irritation, it is still recommended to follow the product safety data sheet, wear protective gloves and goggles, and avoid prolonged contact with skin and eyes.
