Does Sodium Lauryl Sulfate (Toothpaste) Cause Skin Allergic Reactions?

I had patch test recently and it shows allergy reaction on my toothpaste. I also notice that the degree of severity relates to ingredient 'sodium lauryl sulphate'. Does sodium lauryl sulphate actually cause contact dermatitis, or just elevating it's reaction? Thanks in advance.

Allergic contact dermatitis from toothpaste

There may be many reasons to develop allergic contact dermatitis, including cinnamates which are often in toothpaste. Sodium lauryl sulfate is a detergent and often causes an irritant, not just allergic, contact dermatitis. You may need to use a bland toothpaste, such as a baking soda toothpaste without the ingredients to which you react, to see if your reaction improves.
