Sodium lauryl sulfate

SLS is an ingredient common in cleaning and hygiene products. It diminishes the taste of sweetness, as observed in the use of toothpaste containing SLS. It's not carcinogenic when it's applied to the skin or consumed. "In the only carcinogenicity study available, SLS was not carcinogenic in Beagle dogs, though the short study duration and limited details provided limit the significance that can be attached to the data."


It can irritate the skin with prolonged exposure and can cause canker sores when used in toothpaste.
