What is SLS?

Shampoo without SLS is an inexpensive chemical widely used in the manufacturing of several personal hygiene products like shampoos, mouthwashes, toothpastes, soaps and detergents, to name a few. This chemical basically acts as a surfactant that breaks the surface tension between the molecules and separates them so as to allow interaction between the product and the substance for which the former is made. This in turn produces lather/foam thus, making the products more effective cleaners.

Shampoo without SLS

  • It is a skin irritant: SLS is used as a skin irritant while testing several cosmetics in the laboratory.
  • It is basically a pesticide/ herbicide: SLS is generally used to kill insects and weeds. Research has shown that the chemical is an approved pesticide used in organic farming.
  • It is an eye irritant: Research has also shown that the chemical tends to cause cataracts in adults. It also inhibits development of eyes in young children.
  • It emits toxic fumes on heating: SLS releases toxic fumes of sulfur oxide and sodium oxide when heated.
  • It affects body’s tissues: University of Georgia Medicine has proven that chemical free shampoo has the ability to permeate eyes , heart, brain and lever.
  • It pollutes the environment: Manufacturing of SLS is not environment friendly. Emission of cancer causing substances and air particulates takes place during the process.
  • It pollutes groundwater: shampoo without sulfate is toxic to aquatic animals and it also results in bioaccumulation (that means it accumulates in the bodies of aquatic animals.) The chemical is also found in several municipal water filters from where it gets in the house taps.
