Until after 1945, toothpastes contained soap. After that time, soap was replaced by other ingredients to make the paste into a smooth paste or emulsion – such as sodium lauryl sulphate, a common ingredient in present-day toothpaste.
Here are our top ten reasons you should not use anything containing SLS.
- It is a known skin irritant. When cosmetic companies need to test the healing properties of a lotion, they need toirritate the skin first. What do they use to do this? SLS, of course. If you have dandruff, dermatitis, canker sores, or other irritated tissues or skin, it could be due to SLS.
- It pollutes our groundwater. It is toxic to fish and other aquatic animals and has the potential for bioaccumulation (meaning it accumulates in the bodies of the fish.) It also is undetected in many municipal water filters, getting into the tap water that you drink.
- It is actually a pesticide and herbicide. It is commonly used to kill plants and insects. Makers of SLS recently petitioned to have SLS listed as an approved pesticide for organic farming. The application was denied because of its polluting properties and environmental damage.
- It emits toxic fumes when heated. Toxic Sodium Oxides and Sulfur Oxides are released when SLS is heated. Makes a hot shower with an SLS shampoo seem not quite as nice…
- It has corrosive properties. According to the American College of Toxicity, this includes corrosion of the fats and protiens that make up skin and muscle. SLS can be found in garage floor cleanrs, engine degreasers, and car wash soaps.

So in other words they took the soap out and replaced it with poison, sound familiar!?!
The development of toothpastes in more modern times started in the 1800s. Early versions contained soap and in the 1850s chalk was included. Betel nut was included in toothpaste in England in the 1800s, and in the 1860s a home encyclopedia described a home-made toothpaste that used ground charcoal.
Prior to the 1850s, ‘toothpastes’ were usually powders. During the 1850s, a new soap toothpaste in a jar called a Crème Dentifrice was developed and in 1873 Colgate started the mass production of toothpaste in jars. Colgate introduced its toothpaste in a tube similar to modern-day toothpaste tubes in the 1890s.
