# Ethoxylated C9-11 Alcohol with 6 EO Units: A Versatile Surfactant
## Understanding C9-11 Pareth 6
C9-11 Pareth 6, chemically known as Ethoxylated C9-11 Alcohol with 6 EO Units, is a nonionic surfactant widely used in various industrial and consumer applications. This compound is created through the ethoxylation of C9-11 fatty alcohols with 6 moles of ethylene oxide (EO).
The resulting molecule features a hydrophobic carbon chain (C9-11) and a hydrophilic ethoxylate chain (6 EO units), giving it excellent surfactant properties. This balanced structure makes it particularly effective in formulations requiring both oil and water solubility.
## Key Properties and Characteristics
C9-11 Pareth 6 exhibits several notable characteristics:
– Excellent wetting and emulsifying properties
– Good solubility in both water and organic solvents
– Mild surfactant action compared to higher EO variants
– Relatively low foam generation
– Good compatibility with other surfactants
These properties make it particularly valuable in applications where controlled foam and moderate hydrophilic-lipophilic balance (HLB) are required.
## Industrial and Commercial Applications
### 1. Cleaning Products
C9-11 Pareth 6 is extensively used in various cleaning formulations:
– Industrial and institutional cleaners
– Hard surface cleaners
– Degreasers
– Laundry detergents
Its ability to effectively remove oils and greases while maintaining moderate foam levels makes it ideal for these applications.
### 2. Personal Care Products
In the personal care industry, this surfactant finds use in:
– Shampoos and body washes
– Facial cleansers
– Shaving products
– Cosmetic formulations
The mildness of C9-11 Pareth 6 makes it suitable for products that come into direct contact with skin.
### 3. Agricultural Applications
The surfactant properties of C9-11 Pareth 6 are valuable in agricultural formulations:
– Pesticide and herbicide adjuvants
– Crop protection formulations
– Fertilizer additives
It helps improve the spreading and penetration of active ingredients on plant surfaces.
## Environmental and Safety Considerations
C9-11 Pareth 6 is generally considered to have low toxicity and good biodegradability. However, as with all chemical substances, proper handling procedures should be followed:
– Avoid prolonged skin contact
– Use appropriate personal protective equipment when handling concentrated forms
– Follow local regulations for disposal
– Store in cool, dry conditions away from oxidizing agents
The environmental profile of this surfactant makes it a preferred choice in formulations where ecological impact is a concern.
## Formulation Considerations
When incorporating C9-11 Pareth 6 into product formulations, several factors should be considered:
– Optimal concentration ranges (typically 1-15% depending on application)
– Compatibility with other formulation components
– pH stability (generally stable across a wide pH range)
