Lubai Ling/O-8 is a classic nonionic surfactant with core advantages of high-efficiency emulsification, excellent wetting and dispersion, and outstanding chemical stability, widely used in multiple industrial fields such as textile, cleaning, pesticides, and emulsion polymerization.
Detailed Explanation
Lubai Ling/O-8 (fatty alcohol polyoxyethylene (8) ether, C12~14) is a nonionic surfactant that appears as a white to slightly yellow paste or flake. Its chemical structure endows it with an ideal hydrophilic-lipophilic balance value, enabling it to form a stable interfacial film at the oil-water interface, demonstrating strong emulsifying and solubilizing capabilities for mineral oils, animal and vegetable oils, and various organic solvents.
The most notable feature of this product is its "all-around" performance: it can serve as a highly efficient emulsifier, as well as a wetting penetrant and dispersant, achieving multiple functions with a single agent. Additionally, it has good compatibility with anionic, cationic, and amphoteric surfactants, remains stable in acid, alkali, and high-concentration electrolyte salt solutions, exhibits outstanding hard water resistance without forming calcium soap precipitates, making it highly flexible and reliable in complex formulation systems.
Furthermore, Lubai Ling/O-8 shows a high cloud point in aqueous solutions, allowing it to maintain surface activity in high-temperature processing operations. This characteristic makes it particularly excellent in harsh conditions such as high-temperature textile scouring and metal hot cleaning.

Application Suggestions
Lubai Ling/O-8 has a very wide range of applications. Below are typical uses in various fields:
- Textile Dyeing and Finishing: Used as a pretreatment scouring agent, penetrant, and after-dyeing detergent to effectively remove natural fiber impurities and processing oils, enhancing fabric whiteness and capillary effect.
- Industrial and Household Cleaning: Used in formulating metal hard surface cleaners, heavy oil degreasers, and household liquid detergent products, offering strong detergency and easy rinsing.
- Pesticide Formulations: Used as an emulsifier for emulsifiable concentrates, emulsion concentrates, microemulsions, etc., to improve the emulsification and dispersion performance of pesticide technical materials, enhancing dilution stability and spray adhesion.
- Emulsion Polymerization: Used as a primary or co-emulsifier in systems such as acrylate and styrene-acrylic, providing stable monomer pre-emulsification and polymer latex, effectively controlling particle size and system viscosity.
- Papermaking Industry: Promotes ink detachment and dispersion during deinking of waste paper, reducing residue and improving pulp whiteness.
- Leather Processing: Used in wet processes like soaking and degreasing to accelerate hide rehydration and removal of natural fats.
- Metalworking Fluids: Serves as a basic emulsifying component in cutting fluids and grinding fluids, providing lubrication, cooling, and strong degreasing effects.
Precautions
- Hazard: This product causes serious eye damage (GHS05), causes skin irritation (GHS07), harmful if swallowed, and harmful to aquatic life with long-lasting effects.
- Personal Protection: Wear protective gloves, protective clothing, and eye protection during operation. Wash skin thoroughly after handling. Do not eat, drink, or smoke during use.
