There are 3 main lubricant types that are the most commonly available. Water-based lubricant - The most commonly available and generally considered the safest option for people and sex toys. Silicone-based lubricant - Another safe option that is made of silicone.  These are water-proof, longer lasting, and safe for use with latex. Oil-based lubricant - These are typically for masturbation lube and anal lube.  Oil is not safe for use with latex, sex toys, or vaginal sex. In more recent times manufacturers have released what is known as Hybrid lubricant which is a combination of water-based and silicone-based lube.  This lube is typically a creamy white consistency and has the long lasting and slick properties as both other bases.  Hybrid lube is safe to all sex toys and condoms.
