What is emulsifier S-185/O-5?

Emulsifier S-185/O-5 is a fatty alcohol polyoxyethylene ether nonionic surfactant with CAS number 68439-49-6, widely used in textile, pesticide, coating, leather and other industrial fields due to its excellent emulsifying, wetting, dispersing and solubilizing properties.

Detailed Description

Emulsifier S-185/O-5, chemical name fatty alcohol polyoxyethylene ether, also known as polyoxyethylene (35) stearyl ether, steareth-35, PEG-35 stearyl ether, etc., is a high-performance nonionic surfactant produced by Haian Guoli Chemical Co., Ltd. The product appears as a white to light yellow paste, characterized by high active content and low moisture, meeting the requirements of strict industrial formulations for raw material purity and stability.

This product exhibits outstanding chemical resistance, maintaining stable performance in acidic, alkaline and hard water environments, and is not easily inactivated. It also shows good compatibility with anionic, cationic and other nonionic surfactants, offering flexible formulation adaptability for complex multi-component systems. Its excellent emulsifying and dispersing efficiency ensures uniform and stable multiphase systems, while good wetting and penetrating properties accelerate the spreading of treatment liquids on substrate surfaces.

In terms of safety, this product is an industrial chemical that may cause skin and eye irritation, is harmful if swallowed, and is toxic to aquatic life. It should be handled with protective gloves, goggles and protective clothing, and used in well-ventilated areas. The product is not flammable (flash point > 150°C), but should still be kept away from strong oxidizers and high heat sources. Storage temperature is recommended at 5 to 40°C.

Application Suggestions

Emulsifier S-185/O-5, with its multifunctional properties, can serve as an efficient emulsifier, wetting agent and dispersant in multiple industries:

• Pesticide formulations: Provides excellent emulsifying and dispersing properties in emulsifiable concentrates, emulsion concentrates and microemulsions, enhancing formulation stability and ensuring uniform distribution of active ingredients during dilution and use.
• Industrial hard surface cleaners: Exhibits good emulsifying and stripping ability for mineral oils, animal and vegetable oils, improving cleaning efficiency, suitable for metals, plastics and other hard surfaces.
• Metalworking fluids: Acts as an emulsifier and lubricating component, helping to form stable emulsions, reducing friction and wear, improving cooling and rust resistance.
• Textile dyeing and printing auxiliaries: Used in formulating scouring agents, leveling agents, etc., effectively dispersing oil stains and impurities on fibers, promoting uniform dye uptake, improving dyeing and printing quality.
• Leather degreasing and fatliquoring agents: Efficiently emulsifies natural oils during degreasing, promotes uniform oil penetration during fatliquoring, improving leather softness and hand feel.
• Coatings and inks: Helps stable dispersion of resins and pigments in aqueous phase, improving leveling, storage stability and film-forming properties.

Precautions

• Avoid contact with skin and eyes. Wear protective gloves, goggles and face shield during operation.
• Use only in well-ventilated areas. Avoid inhaling vapors or mists.
• Storage temperature is recommended at 5 to 40°C. Avoid direct sunlight. Keep container tightly closed.
• Prevent spills from entering drains or water bodies. Toxic to aquatic life with long-lasting effects.
• Use promptly after opening. Reseal remaining material for storage.
• Keep away from strong oxidizers, strong acids, strong bases and other incompatible materials during storage.
