What are the main features of Peregal O-20?

Peregal O-20 is a nonionic surfactant characterized by its exceptional emulsifying power as the core feature, along with excellent resistance to acids, alkalis, and hard water, good wetting and penetrating properties, and outstanding compatibility with other surfactants.

Detailed Description

Peregal O-20, chemically known as C16-18 fatty alcohol polyoxyethylene (20) ether (CAS No.: 68439-49-6), belongs to the class of nonionic surfactants. The product appears as a milky white to light yellowish waxy solid or paste. Thanks to its outstanding overall performance, it is widely used in various fields such as textile dyeing and finishing, pesticide formulations, household chemicals, and industrial cleaning.

As a nonionic surfactant, the core advantage of Peregal O-20 lies in its strong emulsifying ability—it exhibits excellent emulsification effects on a wide range of oils and organic solvents, making it especially suitable for O/W (oil-in-water) emulsion systems, with the resulting emulsions demonstrating exceptional stability. At the same time, its nonionic nature imparts it with broad compatibility and miscibility, allowing it to be used in combination with anionic, cationic, and zwitterionic auxiliaries and surfactants to produce significant synergistic effects, which is highly valuable in practical formulation development.

In industrial application environments, Peregal O-20 demonstrates excellent acid and alkali resistance stability and outstanding hard water tolerance—it maintains stable surface activity over a wide pH range and is not affected by calcium or magnesium ions, performing efficiently even in hard water conditions. In addition, the product can significantly reduce the surface tension of aqueous solutions, possesses good wetting and penetrating ability on porous materials such as fabrics and leather, and can effectively disperse dyes and pigments in processes like textile dyeing to ensure level dyeing results.

Technical Parameters

Application Recommendations

Based on the six core characteristics of Peregal O-20, the following typical application scenarios are recommended:

• Textile Dyeing and Finishing: Used as an efficient levelling agent and dispersant, slowing down the dye uptake rate, preventing color spots and uneven dyeing, and enhancing dyeing uniformity and color fastness.
• Pesticide Formulations: Used as an emulsifier to prepare aqueous emulsions and microemulsions, reducing the oil-water interfacial tension and improving the effective utilization of pesticides.
• Household Chemicals: Serves as a primary O/W emulsifier or co-emulsifier in creams, lotions, and shampoos, imparting a fine, glossy texture to the product.
• Industrial and Household Liquid Detergents: Provides excellent wetting, penetrating, and emulsifying detergency.
• Metal Processing, Papermaking, Leather: Used as a penetrating and wetting agent, accelerating the penetration of treatment liquors into the material interior to improve processing efficiency.

Precautions

Peregal O-20 is classified as a irritating substance (GHS classification: Skin irritation Category 2, Serious eye irritation Category 2A, Respiratory tract irritation Category 3). Wear protective gloves and goggles when handling, avoid inhaling dust or fumes, and use only in well-ventilated areas. In case of skin contact, wash immediately with plenty of soap and water. In case of eye contact, rinse with water for at least 15 minutes and seek medical attention. The product should be stored in a cool, dry, well-ventilated warehouse, away from strong oxidizers, strong acids, and strong bases, and protected from heat, moisture, and direct sunlight. Oral LD50 (rat) is greater than 2000 mg/kg, falling within the low toxicity range, and it is readily biodegradable.
