Question 4

Does Pingpingjia O-15 meet environmental requirements? Can a test report be provided?

Accepted Answer

Pingpingjia O-15 is a low-toxicity surctant that poses a chronic hazard to aquatic life (H412 classification), requiring strict control of emissions; currently, the Guoli Chemical product database does not include a dedicated environmental test report electronic document for this product. Environmental Compliance Analysis Pingpingjia O-15 (tty alcohol polyoxyethylene (15) ether) as a non-ionic surctant needs to be assessed for its environmental characteristics from three aspects: biodegradability, aquatic toxicity, and regulatory compliance. According to the GHS classification criteria, this product is classified as "Hazardous to the aquatic environment - long-term chronic: Category 3", with hazard statement H412 (Harmful to aquatic life with long-lasting effects). This means that although this product is not a highly toxic chemical, its potential risk to the aquatic ecological environment cannot be ignored and must be properly treated before discharge. From ecotoxicological data, the acute fish toxicity LC50 (96h) of Pingpingjia O-15 is >100 mg/L, and the acute daphnia EC50 (48h) is >100 mg/L. According to the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), these values ll within the chronic aquatic hazard category 3.

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 tty alcohol polyoxyethylene ether with a polymerization degree of 15. This specific chemical structure gives it a very balanced and outstanding performance among nonionic surctants. ### 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 surctants 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, r 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 il 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.

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 surce 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.

Question 10

What are the physicochemical technical parameters of Peregal O-15?

Accepted Answer

Peregal O-15 is a highly hydrophilic nonionic surctant with an HLB value of about 14.5, appearing as a white to slightly yellow paste/solid. It exhibits excellent emulsifying, wetting, and acid/alkali resistance properties, with comprehensive physicochemical parameters suitable for various industrial fields such as textiles, daily chemicals, pesticides, and leather. Detailed Description Peregal O-15 (chemical name: tty alcohol polyoxyethylene (15) ether, CAS: 68439-49-6) produced by Guo Li Chemical is a nonionic surctant synthesized by adding 15 moles of ethylene oxide to C16-18 tty alcohols as the starting agent. Its appearance is a white to slightly yellow paste or solid, with a softening point of approximately 40-45°C. It is readily soluble in polar solvents such as water, ethanol, and acetone, forming a clear solution in water. The product has an active matter content of ≥99%, solid content of ≥99%, and residual free alcohol ≤1%, ensuring high purity and stable performance. The core physicochemical characteristics of Peregal O-15 include: a cloud point of 80-90°C (1% aqueous solution), which means it maintains good surce activity in moderate to high-temperature systems (e.g., industrial cleaning, textile scouring); an HLB value of about 14.5, indicating a highly hydrophilic emulsifier, particularly suitable for preparing O\/W (oil-in-water) emulsions; excellent chemical stability, withstanding high concentrations of alkali (200g\/L NaOH) as well as conventional acidic and hard water conditions, and good compatibility with nonionic, anionic, cationic, and amphoteric auxiliaries. This product is a low-foaming surctant, suitable for industrial operations where excessive foam is undesirable. In terms of safety and environmental impact, Peregal O-15 is a low-toxicity chemical with an acute oral LD50 (rat) of >2000 mg\/kg; its ecotoxicity to aquatic organisms is relatively low, with fish LC50 (96h) and Daphnia EC50 (48h) both >100 mg\/L. However, it can cause skin irritation (Category 2) and serious eye irritation (Category 2A). Operators should wear protective gloves, goggles, and other personal protective equipment, and prevent the product from entering water environments.
