# C9-11 Pareth 6: Properties and Applications in Industrial Formulations
## Introduction to C9-11 Pareth 6
C9-11 Pareth 6 is a nonionic surfactant belonging to the family of alcohol ethoxylates. It is derived from a mixture of C9 to C11 fatty alcohols and contains an average of six ethylene oxide (EO) units. This surfactant is widely used in various industrial applications due to its excellent emulsifying, wetting, and dispersing properties.
## Chemical and Physical Properties
The chemical structure of C9-11 Pareth 6 consists of a hydrophobic alkyl chain (C9-11) and a hydrophilic polyethylene glycol chain (6 EO units). This amphiphilic nature makes it an effective surfactant. Key properties 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): 5-7 (neutral)
– Cloud point: Varies with concentration but typically around 50-60°C
## Key Applications in Industrial Formulations
### 1. Cleaning Products
C9-11 Pareth 6 is extensively used in industrial and institutional cleaning formulations due to its excellent degreasing properties and compatibility with other surfactants. It is particularly effective in:
– Heavy-duty degreasers
– Industrial floor cleaners
– Metal cleaning formulations
– Textile processing aids
### 2. Agricultural Applications
In the agricultural sector, this surfactant serves multiple functions:
– As an emulsifier in pesticide formulations
– To improve wetting and spreading of agrochemicals on plant surfaces
– In adjuvant systems to enhance pesticide efficacy
### 3. Personal Care Products
While primarily an industrial surfactant, C9-11 Pareth 6 finds some applications in personal care products where mildness is not a primary concern:
– Industrial hand cleaners
– Some cosmetic formulations requiring specific emulsification properties
## Formulation Considerations
When incorporating C9-11 Pareth 6 into industrial formulations, several factors should be considered:
– Compatibility with other surfactants (anionic, cationic, or nonionic)
– Optimal concentration for desired performance (typically 1-10%)
– Temperature stability of the final product
– Foaming characteristics (moderate foam generation)
