What is the main component of Peregal O-15?

The main component of Peregal O-15 is fatty alcohol polyoxyethylene (15) ether, which is a nonionic surfactant.

Detailed Description

Peregal O-15 (CAS number: 68439-49-6) has the chemical name fatty alcohol polyoxyethylene (15) ether, belonging to the fatty alcohol polyoxyethylene ether (AEO) series of nonionic surfactants. This product is prepared by the addition polymerization reaction of natural or synthetic high-carbon fatty alcohols (usually C12-C18 fatty alcohols) with approximately 15 moles of ethylene oxide (EO). In the molecular structure, the hydrophilic group is the polyoxyethylene chain (-CH₂CH₂O-)ₙ, and the lipophilic group is the long-chain fatty alkyl group.

Where "15" represents the average degree of ethoxylation (i.e., EO addition moles), this value determines the product's key performance parameters such as the hydrophilic-lipophilic balance (HLB value) and cloud point. With a moderate EO addition number, Peregal O-15 possesses good water solubility along with excellent emulsifying, wetting, and dispersing capabilities, forming the structural basis for its wide applications in textile printing and dyeing, industrial cleaning, cosmetics, pesticide formulations, etc.

The product typically appears as a white to slightly yellow flake or paste-like solid, with excellent stability to acids, alkalis, and hard water. It can be well combined with various types of surfactants including nonionic, anionic, cationic, and zwitterionic types, making it a core component in many industrial formulations.

Basic Product Information

Application Recommendations

Due to its chemical structure characteristics of fatty alcohol polyoxyethylene ether, Peregal O-15 performs outstandingly in the following fields:

• Textile Printing and Dyeing: Acts as an efficient levelling agent and retarding agent, promoting uniform dye penetration and preventing color unevenness and spots.
• Industrial Cleaning: Exhibits excellent emulsifying and degreasing capabilities for mineral oils and animal/vegetable oils, suitable for hard surface cleaning at medium to high temperatures.
• Cosmetics: Used as an O/W emulsifier in formulations such as creams and lotions, providing a fine texture and pleasant skin feel.
• Pesticide Formulations: Used as an emulsifier for emulsifiable concentrates (EC) and aqueous emulsions (EW), improving the dispersibility of the spray liquid and the utilization rate of the active ingredient.

Precautions

This product is a low-toxicity chemical, but may cause skin irritation (H315) and serious eye irritation (H319). It is recommended to wear protective gloves and goggles during operation. It has long-lasting effects on aquatic life (H412) and should be strictly prevented from entering natural water bodies.
