In industrial cleaning, textile dyeing, pesticide emulsification, and personal care formulations, the choice of surfactants often determines the final performance of a product – wh the foam is controllable, wh it can withstand hard water, and wh it remains effective in environments with strong acids and bases.

The Butyl Polyoxyethylene Polyoxypropylene (CAS: 9004-77-7) produced by Hangzhou Danwei Technology Co., Ltd. provides reliable solutions to these issues due to its precise EO/PO ratio structure.

One product, two molecular weights – suitable for various applications

Danwei Technology’s series offers two main specifications:

• MW 1000
• MW 1700

These two specifications differ in their hydroxyl value and HLB value, enabling them to be used in formulations with different polarities. Additionally, we support custom manufacturing according to customer requirements, thus offering flexible supply options.

Not just “low foam”, but also “stability”

The key advantages of this product can be summarized in four terms:

• Low foam – reduces excess foam during cleaning or high-speed stirring, improving process efficiency;
• Resistance to hard water – maintains good dispersion and wetting properties even in water with high calcium and magnesium ions;
• Resistance to acids and bases – can be used effectively within a wide pH range of 3–11;
• Resistance to electrolytes – suitable for complex formulations containing salts or alkalis.

These characteristics enable it to function as an efficient emulsifier and wetting agent in industrial cleaning, textile pre-treatment, paper wetting, pesticide suspending agents, polyurethane foaming, household detergents, and personal care products.

Packaging and storage – convenient and professional

• Standard packaging is 200 KG in iron drums; customized packaging can also be provided according to customer needs.
• Transportation is handled as non-hazardous goods. Storage should be done in a cool and dry place, away from direct sunlight and rain.
