Peregal O-50/100, with its ultra-long EO chain providing excellent emulsification, dispersion, stability, and low foam performance, is widely used in seven major industries including textile printing and dyeing, cosmetics, pesticide formulations, metal processing, papermaking, leather, and industrial cleaning, covering dozens of core processes.
Detailed Description
Peregal O-50/100 is a fatty alcohol polyoxyethylene ether (AEO) series nonionic surfactant produced by Haian Guoli Chemical Co., Ltd., prepared by the addition polymerization of natural C₁₆~C₁₈ fatty alcohols with ethylene oxide (EO). Peregal O-50 has an EO addition number of about 50, while Peregal O-100 has about 100. Both are O\/W (oil-in-water) nonionic emulsifiers. Due to the extremely long polyoxyethylene chain segment, they possess strong hydrophilicity and steric hindrance stabilization capability, making them green chemical auxiliaries with non-toxic, non-irritating, and excellent biodegradability.
The core advantages of this product include: the extremely long EO chain provides outstanding emulsification and dispersion stability; it remains stable over a wide pH range and in high-concentration salt and hard water environments, with excellent electrolyte tolerance; it has extremely low foaming, almost foam-free, making it particularly suitable for processes with strict foam control requirements such as circulating pumping and spraying; and it can be well compounded with anionic, cationic, and other nonionic surfactants to produce synergistic effects.
Seven Application Industries and Specific Processes
I. Textile Printing and Dyeing Industry
- High-temperature and high-pressure leveling: Peregal O-100, due to its high HLB value and high cloud point, performs excellently in high-temperature dyeing of polyester and acrylic fibers, effectively preventing uneven dyeing; Peregal O-50 is more suitable for medium-temperature blended fabric dyeing.
- Scouring and penetrating: Peregal O-50 is used in the pretreatment of cotton fabrics, quickly penetrating into the fiber interior to thoroughly remove natural impurities such as waxes and pectin, improving capillary effect and whiteness.
- Wool scouring: Peregal O-100 gently and efficiently removes wool grease and dirt, avoiding felting and maintaining fabric hand feel.
- Dispersant\/soaping agent: Used for dye dispersion and post-dyeing soaping, improving leveling and color fastness.
II. Cosmetic Industry
- O\/W emulsifier: Peregal O-50 is suitable for emulsifying various oil-soluble ingredients, preparing fine and stable skin creams and lotions with good spreadability.
- Cream stabilizer: Peregal O-100 acts as an auxiliary emulsifier and stabilizer, improving the long-term storage stability of creams and preventing oil-water separation.
- Solubilizer: Peregal O-100, with its long EO chain structure, efficiently and transparently solubilizes fragrances and fat-soluble active ingredients into the aqueous phase system.
III. Pesticide Formulation Processing
- Emulsifier for emulsifiable concentrates: The combination of Peregal O-50 and O-100 is an excellent nonionic component for preparing emulsifiable concentrates of organophosphorus and pyrethroid pesticides, automatically emulsifying when added to water, ensuring uniform spraying of the liquid.
- Auxiliary for oil-in-water emulsions\/microemulsions: Peregal O-100 provides strong steric hindrance stabilization, maintaining uniform suspension of fine droplets of active pesticide ingredients for a long time after dilution.
- Wetting and dispersing for suspensions: Improves the wetting and spreading properties of the liquid on the target.
IV. Metal Processing Industry
- Component of semi-synthetic cutting fluids: Peregal O-50 provides excellent emulsification and wetting properties, forming a stable semi-transparent cutting fluid after compounding, integrating cooling, lubrication, and rust prevention.
- Emulsifier for rolling oils: Peregal O-50 rapidly emulsifies base oils during the rolling of metals such as aluminum and copper, reducing friction and wear, and improving the surface finish of the sheet.
- Preparation of rust-preventive emulsifying oils: Peregal O-100 combines with anions to enhance the electrolyte tolerance of the emulsion system, providing inter-process rust protection for metal workpieces.
V. Papermaking Industry
- Component of deinking agents for waste paper: Peregal O-100 reduces the interfacial tension between ink and fibers, promoting ink detachment and stable dispersion, significantly increasing the brightness of deinked pulp and reducing fiber loss.
- Emulsifier for AKD sizing agents: Peregal O-50 provides rapid emulsification for AKD, preparing a stable sizing emulsion, improving sizing uniformity and paper water resistance.
- Resin obstacle control agent: Peregal O-100 emulsifies and disperses natural resin particles during the pulping process, preventing their accumulation and adhesion that could cause production problems.
VI. Leather Industry
- Soaking auxiliary: Peregal O-50, with its wetting and penetrating power, quickly penetrates into the fiber gaps of the leather, accelerating the rehydration of salted or dried hides, shortening the soaking time.
- Degreasing agent: Peregal O-100 thoroughly removes natural fats from raw hides, providing a clean and uniform fiber substrate for subsequent tanning and dyeing.
VII. Industrial Heavy-Duty Cleaning
- Pretreatment cleaning of fabrics: Peregal O-100 demonstrates excellent emulsification, removal efficiency, and detergency for heavy soils such as seal oil and mechanical grease in high-temperature, strong alkali systems.
- Hard surface cleaning of vehicles and ships: The combination of Peregal O-50 and O-100 is used for cleaning the exteriors of high-speed trains, ships, and construction machinery, quickly removing oil and carbon deposits, with strong alkali resistance and synergistic detergency.
- Low-foam metal cleaning agents: Leveraging its extremely low foaming characteristics, it is used to prepare industrial cleaning agents suitable for circulating pumping and spray cleaning.
Application Recommendations
Dissolution method: It is recommended to slowly add this product to hot water at 40~60°C, stirring continuously until completely dissolved before incorporating into the formulation system. Peregal O-100 can also be dispersed and dissolved in room temperature water. It is recommended to determine the optimal addition amount and dissolution conditions through small-scale trials.
Selection suggestions: Peregal O-50 (EO≈50) emphasizes emulsification and penetration, suitable for medium-temperature processes and systems requiring moderate lipophilicity; Peregal O-100 (EO≈100) has stronger hydrophilicity and a higher cloud point, suitable for high-temperature dyeing, high electrolyte systems, and application scenarios requiring ultimate stability. Compounding the two can produce synergistic effects, balancing emulsification efficiency and system stability.
Precautions
- This product is non-toxic and non-irritating, but it is recommended to wear gloves and safety goggles during operation, avoiding long-term or high-concentration skin contact.
- Store in a cool, dry, and well-ventilated place, with temperature not exceeding 40°C, avoiding direct sunlight and away from strong oxidizers.
- Peregal O-50 is a waxy solid; dissolution in cold water requires continuous stirring and heating; Peregal O-100 is a flaky\/granular solid, dissolving relatively faster.
- Handle spills without contaminating water bodies, contain and collect using inert absorbent materials.
