Water-based lubricant is a product designed to reduce friction during sexual activity, including foreplay, intercourse, and masturbation. It is called "water-based" because water is the key ingredient in the lubricant, and it is typically listed as one of the first ingredients in the formula. Water-based lubricants are the most widely used personal lubricants and are good for sensitive skin. They are also safe to use with condoms, both latex and non-latex, and may decrease the risk of condom breakage. Water-based lubricants can be used in practically any activity, including ones involving silicone toys. They are easy to clean up and do not leave greasy residue or oil stains. Water-based lubricants can be infused with natural thickeners found in plants, such as xanthan gum or agar agar, to give the lubricant a smooth texture. They can also have various agents added for even dispersal, moisture retention, and resistance to contamination. Water-based lubricants tend to be kinder to the body because they are typically more natural and have fewer chemicals. They can be easily reactivated with water or saliva if they dry out during use.
