Peregal O-20 is widely used in seven major industries: textile printing and dyeing, pesticide formulations, daily chemicals, industrial cleaning, metal processing, papermaking, and leather. It plays a core role in processes such as leveling, emulsification, washing and decontamination, penetration, and wetting.

Detailed Description

Peregal O-20 (C16-18 fatty alcohol polyoxyethylene (20) ether) is a high-performance nonionic surfactant. Due to its excellent emulsifying ability, wide pH tolerance (resistance to acids and alkalis), outstanding hard water resistance, and good compatibility, it has become an indispensable functional additive in multiple industrial fields. Its nonionic nature allows it to be compounded with anionic, cationic, and amphoteric surfactants, resulting in significant synergistic effects and a wide range of applications.

In different industry processes, Peregal O-20 plays distinct key roles: as an efficient leveling agent in textile printing and dyeing; as a stable emulsifier in pesticide formulations; as an O/W emulsifier and solubilizer in daily chemicals; as a powerful decontamination component in cleaning products; and as an efficient penetrating and wetting agent in metal processing, papermaking, and leather treatment.

Detailed Application in Various Industries and Processes

1. Textile Printing and Dyeing Industry

As a leveling agent and dispersant, Peregal O-20 is used in textile dyeing processes. It effectively slows down the dyeing rate, promotes uniform distribution of dyes on the fiber surface, prevents dyeing defects such as uneven color and stains, and ensures full and uniform fabric color. It has a good affinity for direct dyes and vat dyes, and can effectively disperse dyes and pigments, improving dyeing uniformity and color fastness.

2. Pesticide Formulations

As an emulsifier, Peregal O-20 is used in the preparation of pesticide emulsion in water (EW) and microemulsion (ME). It significantly reduces the oil-water interfacial tension, forming a stable work emulsion with good dilution properties, thereby improving the utilization rate of pesticide active ingredients and field efficacy.

3. Daily Chemicals

Used as an O/W (oil-in-water) emulsifier and solubilizer in products such as creams, lotions, and shampoos. As a primary or auxiliary emulsifier, it forms a stable oil-in-water system, giving the cream a delicate and shiny texture; simultaneously, it can solubilize oily fragrances and active ingredients into the water system, enhancing product transparency and usage feel.

4. Industrial and Household Liquid Detergents

As a decontamination functional component, Peregal O-20, with its excellent wetting, penetration, and emulsification triple action, quickly removes and disperses oil stains and sweat stains on fabric fibers and hard surfaces, significantly improving the cleaning effect of liquid detergent products.

5. Metal Processing

Used as a penetrant and wetting agent in metal cutting, grinding, and other processing operations. It quickly reduces the surface tension of processing fluids, improves the wetting effect of the liquid on metal surfaces, and enhances cooling and lubrication efficiency.

6. Papermaking Industry

As a penetration and dispersion aid, it improves slurry uniformity and paper quality, promoting uniform coating distribution during paper coating processes.

7. Leather Processing

Used as a penetration aid in processes such as soaking and fatliquoring, it facilitates the penetration of treatment solutions into the leather interior, enhancing the softness and hand feel of the leather, and improving the quality of the finished product.

Application Recommendations

  • Textile Leveling: It is recommended to add 0.5%–2% based on fabric weight in the dye bath, with specific dosage adjusted according to dye type and dyeing process.
  • Pesticide Emulsification: As an emulsifier compounding component, it is usually used in combination with anionic emulsifiers (such as agricultural emulsion 500#, 600# series), with dosage accounting for 5%–15% of the total formulation.
  • Creams and Lotions: When used as the primary emulsifier, the recommended dosage is 2%–5% of the total formula, and better results are achieved when compounded with auxiliary emulsifiers (such as glyceryl monostearate).
  • Liquid Detergents: Recommended dosage is 1%–5% of the total formula, and it can be used synergistically with anionic surfactants such as AES and LAS.
  • Metalworking Fluids: Recommended dosage is 3%–8% of the concentrate, as a penetration and lubrication component.

Precautions

  • This product is a milky white to light yellow waxy solid or paste. It is recommended to pre-dissolve in warm water or heat to melt before adding to ensure uniform dispersion.
  • It is a low-toxicity substance (oral LD50 > 2000 mg/kg), but it carries risks of skin irritation (H315), serious eye irritation (H319), and respiratory irritation (H335). Protective gloves and goggles should be worn during operation.
  • Store in a cool, dry, well-ventilated warehouse, keep containers tightly closed, away from strong oxidizers and strong acids/bases, and avoid heat, moisture, and direct sunlight.
  • It is readily biodegradable and has low toxicity to aquatic organisms. It is not classified as PBT/vPvB, but direct discharge into water bodies should be prevented.
