Toothpaste brands with SLS.

Quick answer

Sodium lauryl sulfate (SLS) is the detergent that makes many toothpastes foam. In Klyyr's 2026 audit of 50 toothpaste labels, 14 products from 10 brands list it. Most are conventional fluoride pastes, 12 of 22. Only 2 of the 28 hydroxyapatite pastes list it. Six of the 23 pastes that claim whitening list SLS.

SLS is permitted in toothpaste. The ADA lists it among ingredients reported as contact irritants, and people with recurrent canker sores sometimes avoid it. Klyyr One+ uses sodium cocoyl glutamate instead.

How to choose

If you get canker sores

Some people with recurrent canker sores try SLS-free toothpaste. The evidence is limited, so talk to your dentist if sores keep coming back.

If you want a whitening paste without SLS

17 of the 23 whitening pastes Klyyr recorded list no SLS. The whitening claim audit shows what each one whitens with.

If you want low foam

SLS-free pastes foam less. That is a feel, not an efficacy result. See low-foam toothpaste.
