Is Sodium Lauryl Sulfate (SLS) safe to use?
The fact is that there is no accredited research which supports the largely internet-fuelled rumours, (see Urban Legends under Toxins www.snopes.com) about SLS. A recent controlled study conducted at Cambridge University found that there was no difference in the occurrence, severity or duration of canker sores between SLS and non-SLS toothpastes. Other companies such as Tom’s of Maine, Ecover or Weleda in the wholefood world have come to the same conclusions so the idea of SLS in toothpaste being hazardous to health is, to say the least, very contentious. We continue to monitor the situation vigorously but feel that it would not be appropriate to make a change in the present circumstances to an ingredient with a long history of safe use.
