Introduced in 1904 by pharmacist Van Horn and Sawtell as a surgical lubricant, K-Y is a water-based personal lubricant, today commonly used as a lubricant for sexual intercourse. It does not react with latex condoms or silicone rubber-based sex toys. While K-Y has a tendency to dry out during use, it can be reactivated by the addition of saliva. K-Y Jelly has been available over the counter in the United States since 1980.
The origins of the brand name are unknown. Some say it was created in K-entuck-Y, other say the letters represent the main ingredients of the product. In 2014, Reckitt Benckiser took over the K-Y brand from Johnson & Johnson.
