Octylphenol Ethoxylates, commonly known as the OP series, are a group of nonionic surfactants widely utilized across various industries. These compounds are formed by the reaction of octylphenol with ethylene oxide, with the number of ethylene oxide units dictating their specific properties and applications. As a leading chemical supplier, understanding the nuances of the OP series is crucial for B2B buyers seeking to optimize their formulations and procurement strategies.

The physical characteristics of Octylphenol Ethoxylates vary significantly with the degree of ethoxylation. Lower ethoxylates, such as OP-4 and OP-6, tend to be liquids that are soluble in oil and organic solvents, making them excellent W/O (water-in-oil) emulsifiers. They find applications in industrial cleaning and textile processing. As the ethoxylation increases, the surfactants become more water-soluble and transition to pastes or solids. Higher ethoxylates, like OP-10, OP-15, and OP-20, exhibit superior water solubility and are effective as O/W (oil-in-water) emulsifiers, wetting agents, dispersants, and detergents.

The applications of the OP series are diverse. In industrial cleaning, they serve as powerful degreasers. Within the textile industry, they function as leveling agents, dispersants, and antistatic agents. The oilfield sector utilizes them as emulsifiers for crude oil and fuel oils, as well as penetrants. Furthermore, in cosmetic formulations, they act as emulsifiers and wetting agents, contributing to product stability and spreadability. For many of these uses, sourcing a reliable supplier for chemicals like OP-10 is paramount.

When considering the purchase of Octylphenol Ethoxylates, B2B buyers often focus on key technical specifications such as appearance, cloud point, HLB value, and hydroxyl value. The HLB (Hydrophilic-Lipophilic Balance) value is particularly important as it indicates the surfactant's suitability for emulsification, wetting, or detergency. For instance, OP-10, with an HLB typically between 13-14, is well-suited for emulsification and wetting tasks.

For businesses looking to buy OP-10 or other OP series surfactants, a strategic approach to sourcing is recommended. Identifying manufacturers and suppliers in regions like China can offer competitive pricing and a wide range of product grades. Evaluating potential suppliers based on their production capacity, quality control, and customer service is essential.
