Peregal O
Overview
Peregal O is a nonionic surfactant belonging to the polyoxyethylene alkyl ether family. It is produced by the ethoxylation of lauryl alcohol, resulting in a compound with both hydrophilic (ethylene oxide) and hydrophobic (alkyl chain) components. This versatile chemical has been widely used since the mid-20th century, particularly in textile processing where it serves as an excellent leveling and dispersing agent. Its molecular structure can be tailored by adjusting the number of ethylene oxide units, allowing for customization of properties like solubility and surface activity.
Physical and Chemical Properties
Peregal O typically appears as a viscous liquid or soft paste, with its physical state depending on the degree of ethoxylation. The compound exhibits excellent stability in hard water and across a wide pH range, making it suitable for various industrial applications. Key chemical properties include its cloud point (which varies with ethylene oxide content), low foaming characteristics, and excellent emulsification capabilities. As a nonionic surfactant, it doesn't ionize in aqueous solutions, contributing to its compatibility with other types of surfactants and chemicals in formulations.
Main Applications
In the textile industry, Peregal O is primarily used as a leveling agent in dyeing processes, helping to achieve uniform color distribution. It also functions as a detergent and emulsifier in fabric scouring and finishing operations. The cosmetic industry utilizes this surfactant in shampoos, bath products, and skin cleansers due to its mildness and good foaming properties. Industrial applications include use in metal cleaning formulations, pesticide emulsifiers, and as a component in latex polymerization processes.
Safety and Storage
Peregal O is generally considered low in toxicity but may cause mild skin and eye irritation upon direct contact. Proper personal protective equipment including gloves and safety glasses should be worn when handling the concentrated product. For storage, keep containers tightly sealed in a cool, well-ventilated area away from strong oxidizers. The material is stable under normal conditions but may degrade if exposed to excessive heat over prolonged periods. Shelf life typically exceeds two years when stored properly.
B2B Procurement Guide
When procuring Peregal O, buyers should specify the desired degree of ethoxylation (typically expressed as the number of EO units), which directly affects performance characteristics. Common variants range from 7-23 EO units. Quality indicators include clear appearance (no sediment), consistent viscosity, and meeting specified active matter content (usually 99%+). Bulk purchases (drum quantities or larger) typically offer significant cost advantages. Reputable suppliers should provide technical data sheets and certificates of analysis with each shipment.
