Danger of Hypotears due to Benzalkonium Chloride used as a preservative.
After using this product for many years and loving it, I find out that it contains Benzalkonium Chloride as a preservative which has been demonstrated to have extremely adverse effects on corneal cells. It is also rather malicious that this product does not list Benzalkonium Chloride as a preservative used.
