Sodium Lauryl Sulfate
Transcript of Sodium Lauryl Sulfate
2. Cleaning Agent
What is it?
Sodium Lauryl Sulfate
'Water' - H2O
'Oxygen' - O2
'Carbon Dioxide' - CO2
Main ingredient in detergent, is also found in toothpaste, shampoo and skincare products.
Fats (oils & grease) do not dissolve in water, so how can we clean oil and grease off our clothes and out of our hair?
How does it work?
This is a single Sodium Lauryl Sulfate molecule:
'Lipo-' : fat (oil & grease)
'Hydro-' : water
'-philic' : friends (3)
How it works...
'Sodium Lauryl Sulfate' - NaC12H25SO4
Sodium Lauryl Sulfate is toxic, but in low concentrations (<1%) helps remove oil and grease from clothing and hair. (1)
That's where Sodium Lauryl Sulfate came in!
