According to the technical data of Guoli Chemical, the core advantages of Peregal O-80 lie in its **extremely high HLB value (18.5), outstanding chemical stability, and comprehensive safety and environmental protection characteristics**, which make it perform better than other conventional fatty alcohol polyoxyethylene ethers in scenarios requiring strong hydrophilicity and high temperature/wide pH processes.
Based on the detailed data returned by the system during your query, the following is a specific analysis of the advantages of Peregal O-80:
### 1. Excellent emulsification and hydrophilic ability
Peregal O-80 has a very high degree of ethylene oxide (EO) polymerization (n≈80), which gives it strong hydrophilicity.
* **High HLB value**: HLB value up to **18.5**. Much higher than low-EO products in the Peregal series, making it an efficient emulsifier for preparing oil-in-water (O/W) emulsions, with high emulsification efficiency and excellent emulsion stability.
* **Excellent solubilization effect**: Its solubilization ability for hydrophobic substances (such as fragrances, oils, oil-soluble dyes) is significantly better than similar products with low EO numbers.
### 2. Wide process applicability and stability
* **Chemical stability**: It remains active under conventional acid, alkali, and high-hardness water conditions. Compared with some ionic surfactants sensitive to pH, it has wider applicability.
* **Thermal stability**: Cloud point **>100°C** (1% aqueous solution), meaning it will not precipitate in high-temperature processes near boiling, maintaining clarity and effective surface activity, which is advantageous in high-temperature dyeing or cleaning.
### 3. Excellent purity and physicochemical indicators
Its high active content and strict by-product control ensure stable batch-to-batch application performance.
* **High active content**: Active matter content **≥99%**, moisture **≤1.0%**.
* **Low by-products**: Free alcohol content **≤3%**, which helps reduce odor and improve the low-temperature stability of the final formulation.
* **Saturated structure**: Iodine value **≤2**, a derivative of saturated fatty alcohol, with more stable chemical properties, good oxidation resistance, and not prone to discoloration.
### 4. Top-level safety and environmental performance
Peregal O-80 meets the strictest health and environmental regulations, providing reliable safety endorsement for your products.
* **Human safety**: Toxicological assessment shows it is practically non-toxic (LD50 > 5000 mg/kg) and **non-irritating** to skin and eyes, making it very suitable for personal care and household detergent formulations.
* **Environmentally friendly**: Readily biodegradable (28-day degradation rate > 60%), with very low toxicity to aquatic organisms (LC50/EC50 > 100 mg/L), meeting increasingly stringent environmental requirements.
**Typical differences compared to other categories**:
* **Compared with Peregal O-20/O-25**: Peregal O-80 has a higher HLB value and stronger hydrophilicity, making it more suitable as an O/W emulsifier or solubilizer for high-oil-content systems.
* **Compared with AEO-9 (MOA-9)**: The cloud point of AEO-9 is mostly around 60-80°C, while the cloud point of Peregal O-80 is >100°C. In textile processes requiring high-temperature boiling or high-pressure dyeing, Peregal O-80 has irreplaceable advantages.
**Application recommendations**:
When constructing **long-term stable, high temperature/acid-alkali resistant, and safety-critical** O/W emulsification, solubilization, and dispersion systems, Peregal O-80 is an ideal choice. It is recommended for high-end cosmetic creams, high-temperature leveling agents, pesticide water-based preparations, and high-quality industrial cleaning agents. The recommended dosage varies according to the system, typically 1% to 10% of the total system weight.
