Low osmolality lubricants are water-based formulas with little or no glycols like glycerin, propylene glycol, or propanediol. These less concentrated formulas are less likely to cause irritation or promote infection. At SLICK.SEXY, low osmolality lubricants have a known or reasonably estimated osmolality of less than 700mOsm/kg.
Osmolality describes how concentrated a water-based lubricant is. Because highly concentrated lubes can cause irritation, promote infection, and impact fertility, we think osmolality is one of the most important things to know about your water-based lubricant. Here’s how to find safer, low-osmolality formulas.
