OXBALLS OXLube Thick Silicone is a silicone lubricant with only three ingredients and nothing added to bulk it out. The 8.5 oz bottle is the larger of the two sizes, aimed at people who already know they like a heavy, cushioned silicone glide and get through lube quickly. OXBALLS built it to go with its own toys, which is why the brand is so specific about what it is safe with.
The full ingredient list is cyclopentasiloxane, dimethicone and dimethiconol. That's it: no water, no glycerin, no preservatives, no fragrance. Each is a type of silicone, and the blend is what gives the lube its body. Because nothing in it evaporates the way water does, it stays slippery until you wash it off, and it doesn't turn tacky as it sits on skin.
Straight from the bottle it's a rich, syrupy liquid rather than a gel. It warms quickly between your fingers, spreads thin and feels almost velvety. OXBALLS describes it as melty and very slick, and advises using it sparingly. A dot the size of a fingertip covers more than you'd expect; start there and add more only when the glide starts to fade. Overdoing it just leaves you with extra to clean up.
Thick silicone lube is popular for anal play because it doesn't soak into skin or dry out partway through. It also holds up in the shower or bath, where water-based lube rinses away. For long hand sessions and stroking, the lasting slip means fewer pauses to reapply. With hard toys in glass or metal it gives a smooth, cushioned feel.
Water-based lube is lighter, washes off with water and is the default pairing for most silicone toys, but it dries out and needs topping up. Thick silicone trades easy cleanup for staying power: one application can last a whole session, it won't get sticky, and a little goes a long way, so a bottle this size lasts a long time. If you've found water-based lubes thin out too fast, this is the swap to try.
OXBALLS says this formula is safe with condoms and with toys of every material, naming its own platinum silicone, FLEXtpr, latex, glass and metal. That's unusual: many silicone lubes come with a warning about silicone toys. Silicone quality still varies between brands, so with a toy from another maker, try a small spot on the base first and check it after an hour.
Water alone won't shift it. Wash skin with soap and warm water, and clean toys with hot soapy water. Silicone lube can mark fabric, so put a towel down and wipe spills before they soak into sheets. Floors and tiles get slippery fast; mop up drips in the shower straight away.
If you want to try it before committing to a big bottle, the 4.4 oz Thick Silicone is the same formula. OXBALLS also makes a hybrid OXLube for a creamier feel that washes off more easily.
