SUMMARY

3. INTRODUCTION (cont.)

POLYETHOXYLATED TALLOW AMINE
(POEA)
 Non-ionic
surfactants
 Be composed of tallow amine and 2 chains of
ethoxylate
 POEA molecules will be described by the number
of carbon atoms in the tallow atom moity and the
number of ethyloxylate units

4. INTRODUCTION (cont.)

POLYETHOXYLATED TALLOW AMINE
(POEA)
range of Ka is 6.5 – 7.0
 Produced by ethoxylation process
A

Ethoxylation process
 Tallow
amines reacted with ethylene oxides in
presence of catalyst in process

5. INTRODUCTION (cont.)


6. APPLICATIONS

METAL INDUSTRIES
 Rust
preventives agents
 Corrosion inhibitors
 Metal lubricants

PLASTIC INDUSTRIES
 Textile

auxiliaries
dye leveler

7. APPLICATIONS (cont.)

AGROCHEMICAL INDUSTRIES
 Surfactant
 To
additives in glyphosate formulations
change various physical properties
 May be added as wetting agents, emulsifiers, or
dispersants
 Increases the efficacy of glyphosate
 An excellent performance of emulsification and even
dying

8. ENVIRONMENTAL EFFECTS



A half-life in soils of less than 7 days
Washout from soil is likely to be minimal
Half-life in bodies of water would be about 2
weeks

9. TOXICITY




Be harmful if ingested
Causes skin irritation
Causes eye irritation
Be harmful to a variety of aquatic wildlife

10. TOXICITY (cont.)

11. SUMMARY





Non-ionic surfactants
Used in many glyphosate formulations
Be harmful to aquatic wildlife and many
mammals
Affect to environment
Play an important role in many industries
especially agriculture industries
