C9-11 Pareth 6: Properties and Applications in Industrial Formulations

Introduction

C9-11 Pareth 6 is a nonionic surfactant derived from the ethoxylation of C9-11 fatty alcohols. It is widely used in industrial formulations due to its excellent emulsifying, wetting, and solubilizing properties. This article explores the key characteristics of C9-11 Pareth 6 and its diverse applications across various industries.

Chemical Properties

C9-11 Pareth 6 is a clear to slightly hazy liquid with a mild odor. Its chemical structure consists of a hydrophobic C9-11 alkyl chain and a hydrophilic polyoxyethylene (6 EO) chain. This balanced structure gives it amphiphilic properties, making it effective in reducing surface tension between different phases.

Key properties include:

• Molecular Weight: Approximately 440-460 g/mol
• HLB Value: 12-13 (moderate hydrophilicity)
• Solubility: Soluble in water and most organic solvents
• Cloud Point: Around 50-60°C (1% aqueous solution)

Industrial Applications

1. Cleaning Products

C9-11 Pareth 6 is extensively used in industrial and institutional cleaning formulations. Its ability to emulsify oils and greases makes it valuable in:

• Heavy-duty degreasers
• Industrial floor cleaners
• Metal cleaning formulations

2. Agricultural Formulations

In agrochemicals, C9-11 Pareth 6 serves as an effective emulsifier and wetting agent for:

• Pesticide formulations
• Herbicide concentrates
• Fungicide emulsions

3. Textile Processing

The textile industry utilizes C9-11 Pareth 6 in various processes including:

• Fiber lubrication
• Dye leveling
• Scouring operations

4. Personal Care Products

While primarily an industrial surfactant, C9-11 Pareth 6 finds some applications in personal care as:

• Secondary emulsifier in creams
• Foam booster in cleansing products
• Solubilizer for fragrances

Formulation Advantages

C9-11 Pareth 6 offers several benefits in industrial formulations:

• Excellent compatibility with other surfactants
• Good electrolyte tolerance
• Stable performance across a wide pH range
• Low foam generation suitable for spray applications

Safety and Handling

While generally considered safe for industrial use, proper handling precautions should be observed:

• Use personal protective equipment when handling concentrated material
• Avoid prolonged skin contact
• Store in well-ventilated areas away from strong oxidizers

Conclusion

C9-11 Pareth 6 is a versatile surfactant that plays a crucial role in numerous industrial applications. Its balanced hydrophilic-lipophilic properties, combined with good formulation flexibility, make it a valuable component in cleaning products, agricultural chemicals, textile processing, and other industrial formulations. As industries continue to seek effective and efficient surfactants, C
