Ethoxylated C9-11 Alcohol with 6 EO Units: A Versatile Surfactant

Ethoxylated C9-11 alcohol with 6 ethylene oxide (EO) units, commonly known as C9-11 Pareth 6, is a nonionic surfactant with a wide range of industrial and commercial applications. This chemical compound is created through the ethoxylation of a C9-11 fatty alcohol, resulting in a product with excellent emulsifying, wetting, and cleaning properties.

Chemical Structure and Properties

The molecular structure of C9-11 Pareth 6 consists of a hydrocarbon chain (C9-11) attached to a polyoxyethylene chain containing 6 EO units. This combination gives the molecule both hydrophobic and hydrophilic characteristics, making it an effective surfactant. Key properties include:

• HLB value of approximately 12-13
• Clear to slightly hazy liquid appearance
• Mild characteristic odor
• Good solubility in water
• Low foam generation

Industrial Applications

C9-11 Pareth 6 finds extensive use across multiple industries due to its balanced surfactant properties:

Cleaning Products

This ethoxylated alcohol serves as a key ingredient in various cleaning formulations, including:

• Industrial and institutional cleaners
• Hard surface cleaners
• Dishwashing liquids
• Degreasers

Personal Care

In cosmetic and personal care products, C9-11 Pareth 6 functions as:

• An emulsifier in creams and lotions
• A mild surfactant in shampoos and body washes
• A solubilizer for fragrances and oils

Textile Processing

The textile industry utilizes this surfactant for:

• Fiber lubrication
• Dye leveling
• Scouring processes

Advantages Over Other Surfactants

C9-11 Pareth 6 offers several benefits compared to similar ethoxylated alcohols:

• Better performance in hard water conditions
• Improved compatibility with other formulation ingredients
• Lower irritation potential than higher EO variants
• More efficient at lower use concentrations

Safety and Handling

While generally considered safe for industrial use, proper handling procedures should be followed:

• Use appropriate personal protective equipment (PPE)
• Avoid prolonged skin contact
• Store in well-ventilated areas away from oxidizers
• Follow local regulations for disposal

Material Safety Data Sheets (MSDS) should always be consulted before working with this chemical.

Environmental Considerations

C9-11 Pareth 6 demonstrates favorable environmental characteristics:

• Readily biodegradable under aerobic conditions
• Low bioaccumulation potential
• Minimal toxicity to aquatic organisms at typical use levels

However, as with all surfactants, proper wastewater treatment is recommended to minimize environmental impact.

Future Outlook

The demand for C9-11 Pareth 6 is expected to grow steadily, driven by:

• Increasing need for effective yet mild surfactants
