Is sodium lauryl sulfate found in toothpaste and cosmetics actually a poison in cummulated levels?

A soap: It not typically found in toothpaste and not intended to be ingested. It is a soap found in many liquid soaps.

Allergen: Sodium lauryl sulfate (sls) is a commonly used detergent and inactive ingredient; many have developed an allergy to it...

Possibly: Sodium laural sulfate is a detergent. It is what causes the foam when brushing teeth. It is a skin irritant and if you are predisposed to cancer sores it will aggravate the condition. It has been suggested for use as an insecticide. I try to avoid it as much as possible.
