Silicone-based lubricants are usually formulated with fewer than four ingredients and do not contain any water. Silicone lubricants offer a different feel from water-based personal lubricants. Silicone-based lubricants are not absorbed by skin or mucus membranes, and consequently last longer than water-based lubricants. Many different silicone lubricants are commercially available with varying quality and performance. Not all silicone-based lubricants are
certified latex-safe, but silicone-based lubricants have not been shown to increase the risk of HIV transmission during anal intercourse, as some water-based lubes have.

Silicone-based lubricants are not usually recommended for use with sex toys or other products that are made from
silicone because the formula may dissolve the surface making it sticky to the touch, and cause disintegration of the item over time.[
