K-Y Jelly is a water-based, water-soluble personal lubricant, most commonly used as a lubricant for sexual intercourse and masturbation. A variety of different products and formulas are produced under the K-Y banner, some of which are not water-soluble.
Introduced in January 1904 by pharmaceutical company and suture manufacturer Van Horn and Sawtell of New York City, and later acquired by Johnson & Johnson, K-Y Jelly's original stated purpose was as a surgical lubricant, and it was often chosen by doctors because of its natural base. The product is now more widely used as a sexual lubricant to supplement the moisture required for performing sexual acts.
Unlike petroleum-based lubricants, K-Y jelly is biologically inert, reacting with neither latex condoms nor silicone-based sex toys, and contains no added colors or perfumes. It is non-staining and easy to clean up. Despite having a thick consistency and a tendency to dry out during use, it can be "reactivated" by the addition of saliva or water.
The product contains no spermicide and thus cannot be used to prevent pregnancy. A formulation containing nonoxynol-9 was removed from the market after the spermicide was found to facilitate the spread of HIV.
K-Y NG uses glycerin and hydroxyethyl cellulose as the lubricant, with chlorhexidine gluconate, glucono delta-lactone, methylparaben and sodium hydroxide as antiseptic and preservative additives. The liquid form of the product combines glycerin with propylene glycol, sorbitol, and Natrosol 250H (a brand of hydroxyethyl cellulose) for lubrication, with benzoic acid, methylparaben and sodium hydroxide as additives.
It is used by dentists to cover composite restorations when light curing. This prevents the oxygen inhibitation layer which causes marginal discolouration of restorations.
