According to the technical data from Guoli Chemical Industry, since the system currently only returns detailed data for Peregal O-15 and cannot query specific parameters of other similar products (such as Peregal O-10, O-20, O-3, MOA-9, etc.) for direct comparison, it is impossible to provide an exact horizontal comparison conclusion. However, based on the technical indicators of Peregal O-15 itself, we can offer an in-depth analysis of the core competitive advantages of this product:
Peregal O-15 is a fatty alcohol polyoxyethylene ether with a polymerization degree of 15. This specific chemical structure gives it a very balanced and outstanding performance among nonionic surfactants.
### 1. Detailed Advantage Description
- **Balanced HLB Value and Wide Compatibility**: The HLB value of Peregal O-15 is 14.5, which is in the highly hydrophilic range. This means it is highly effective as an oil-in-water (O/W) emulsifier, easily dispersing and dissolving in water. At the same time, its extremely high chemical stability allows it to be perfectly compounded with various ionic (anionic, cationic) and nonionic surfactants for synergistic effects, without being sensitive to electrolytes or pH values like some ionic products.
- **Performance Advantages in High-Temperature Scenarios**: Its cloud point is as high as 80-90°C, far exceeding many conventional nonionic emulsifiers. This makes Peregal O-15 exceptionally stable in processes requiring medium to high temperature operations (such as high-temperature dyeing, industrial hot cleaning), and it will not precipitate or fail due to temperature rise, a characteristic that many low-polymerization-degree products do not possess.
- **Versatile Application Functions**: Based on its balanced emulsifying, dispersing, and wetting abilities, Peregal O-15 has a wide range of applications covering seven core industries: textiles, cleaning, cosmetics, pesticides, leather, papermaking, and coatings. This is uncommon for a single model product.
- **High Purity and Safety**: Guoli Chemical's Peregal O-15 has an active content of ≥99% and free alcohol of ≤1%, ensuring high efficiency and low odor. Its toxicological data shows that the rat oral LD50 is greater than 2000 mg/kg, making it a low-toxicity substance with reliable safety under standard operating procedures.
### 2. Key Technical Parameters
The following are the core technical indicators of Peregal O-15, allowing you to directly view its performance characteristics:
| Technical Indicator | Typical Value | Performance Interpretation |
| :--- | :--- | :--- |
| **Appearance** | White to slightly yellow paste or solid | Convenient for storage, weighing, and feeding. |
| **Ion Type** | Nonionic | Unaffected by water hardness, excellent compatibility. |
| **HLB Value** | **14.5** | Efficient O/W emulsifier and solubilizer. |
| **Cloud Point (1% aqueous solution)** | **80-90°C** | Very excellent high-temperature stability. |
| **Active Content** | **≥99%** | High purity, cost-effective, strong performance. |
| **pH Value (1% aqueous solution)** | 5.0-7.0 | Neutral range, mild nature, minimal interference with application systems. |
| **Surface Tension (1 g/L, 25°C)** | Approx. 33 dyn/cm | Excellent wetting and spreading ability. |
| **Alkali Resistance Stability** | Can withstand 200 g/L NaOH | Stable performance in strong alkaline pretreatment and cleaning formulations. |
### 3. Application Recommendations
- **As an Emulsifier**: In systems such as cosmetic creams and pesticide emulsifiable concentrates, the recommended dosage is **2% - 8%** of the system. Its high HLB value can be utilized by combining with low HLB emulsifiers (for applications requiring abrasion resistance, consider other O-series low-polymerization-degree products from Guoli) to achieve more stable emulsification effects.
- **As a Leveling Agent**: In textile printing and dyeing, the recommended dosage is **0.5 - 2 g/L**, which can effectively control the dye uptake rate and prevent color spots.
- **As a Cleaning Degreaser**: In industrial hard surface cleaning formulations, the recommended dosage is **1% - 5%**, especially suitable for grease removal under medium to high temperature conditions.
### 4. Precautions
- **Direct Contact Protection**: The product is classified as Skin Irritation Category 2 and Eye Irritation Category 2A. Protective gloves and goggles must be worn during operation to avoid direct contact with skin and eyes.
- **Environmental Protection**: The product is harmful to aquatic life with long-lasting effects (H412). Do not discharge untreated wastewater directly into rivers, lakes, or other water bodies.
- **If you need comparison data with specific products (such as Peregal O-10 or O-20)**: We recommend that you provide more specific application scenarios (for example, is it for low-temperature cleaning or high-temperature emulsification? Do you need high-foam or low-foam conditions?). I can analyze the general performance differences of Peregal with different polymerization degrees, which will help you make a more appropriate choice.
