Bests & Worsts Reviews from Amazon

One of the ingredients in the spray is Sodium Lauryl Sulfate. This is a common ingredient, but usually at 1% and in products like shampoo that you rinse off immediately. My research on the internet showed that at 2% (this product contains 2.2%) it can cause various problems ... skin irritation and possibly cancer. Frequent use would increase the risk. Since this is not a product that one would normally rinse off until your next shower (which could be up to 24 hours) and which you would use frequently if you are outside daily in an area which is heavily infested with ticks, this is not a product that I will use or that I would recommend.
