Ethoxylated C9-11 Alcohol with 6 EO Units
# Ethoxylated C9-11 Alcohol with 6 EO Units: A Versatile Surfactant
## Introduction to C9-11 Pareth 6
C9-11 Pareth 6, also known as Ethoxylated C9-11 Alcohol with 6 EO Units, is a nonionic surfactant widely used in various industrial and consumer applications. This chemical compound is created through the ethoxylation of C9-11 fatty alcohols with approximately 6 ethylene oxide (EO) units.
## Chemical Properties and Structure
The molecular structure of C9-11 Pareth 6 consists of a hydrocarbon chain (C9-11) attached to a polyoxyethylene chain containing about 6 ethylene oxide units. This combination gives the molecule both hydrophobic (water-repelling) and hydrophilic (water-attracting) properties, making it an effective surfactant.
Key characteristics include:
- Appearance: Clear to slightly hazy liquid
- Solubility: Soluble in water and most organic solvents
- HLB value: Approximately 12-13 (moderate hydrophilicity)
- pH (1% solution): Typically 5-7
## Applications in Various Industries
Personal Care Products
C9-11 Pareth 6 is commonly used in shampoos, body washes, and other cleansing products due to its mildness and good foaming properties. It helps to remove dirt and oils while being gentle on the skin.

Household Cleaners
In household cleaning formulations, this surfactant serves as an effective degreaser and emulsifier, particularly in all-purpose cleaners, dishwashing liquids, and hard surface cleaners.
Industrial Applications
The chemical finds use in textile processing, agricultural formulations, and as a wetting agent in various industrial processes where moderate surfactant properties are required.
## Advantages of C9-11 Pareth 6
Compared to other surfactants, C9-11 Pareth 6 offers several benefits:
- Excellent compatibility with other surfactants
- Good emulsifying properties
- Relatively low irritation potential
- Biodegradable under appropriate conditions
- Stable across a wide pH range
## Safety and Environmental Considerations
Human Safety
While generally considered safe for use in cosmetic and household products, proper handling procedures should always be followed. The material may cause mild eye irritation and should be rinsed thoroughly if contact occurs.
Environmental Impact
C9-11 Pareth 6 is considered readily biodegradable under aerobic conditions. However, like all surfactants, it should be prevented from entering waterways in concentrated form to avoid potential aquatic toxicity.
## Conclusion
Ethoxylated C9-11 Alcohol with 6 EO Units represents a versatile surfactant option that balances performance with relatively low environmental impact. Its moderate hydrophilic-lipophilic balance makes it suitable for a wide range of applications where controlled surface activity is required. As with all chemical ingredients, proper formulation and usage are essential to maximize benefits while minimizing potential risks.
