XtoysSliquid Naturals Tsunami Ultra Thick Gel 125ml Review
Editor's opinion
Sliquid Tsunami is a water-based gel lubricant built for a fuller, cushioning feel rather than a thin, slippery one. Its glycerine- and paraben-free formula suits sensitive users and works with all toy materials, though like any water-based product it will need topping up during longer sessions.
Most lubricants sit at one of two extremes: thin and fluid, or thick and tacky. Sliquid Tsunami aims for a middle ground, using plant cellulose to build a gel with genuine body that stays where you put it. The idea is cushioning without the greasiness of an oil or silicone product.
What a buyer is really weighing here is texture against longevity. A thicker water-based gel gives you that reassuring, padded feel and easy clean-up, but water-based formulas are inherently shorter-lived than silicone. This review looks at what the specification actually means for how you would use it day to day.
The good and the bad
What works
- Glycerine and paraben free, a sensible choice for sensitive skin
- Thicker gel body that stays in place rather than running off
- Water-soluble, so it rinses away with just warm water
- Safe with every toy material, including silicone
- 100 percent vegan and non-staining on skin and sheets
What to be aware of
- Water-based, so it will dry out faster than silicone and needs reapplying
- Not suitable for use in the shower or bath, as water washes it away
- A thick gel feel is a matter of taste and will not suit everyone
Buy it if
Anyone who wants a cushioning, body-safe lubricant with a clean ingredient list, particularly those with sensitive skin who avoid glycerine, and anyone using silicone toys that rule out silicone lube.
Skip it if
People who want a lubricant to last through a long session without reapplying, or who want to use it in water. A silicone-based product suits both of those better, provided your toys are silicone-safe.
Design and formula
Tsunami is a water-based gel that gets its thickness from plant cellulose rather than from glycerine, which many thicker lubricants rely on. That matters: glycerine is a common irritant for some people, and its absence here, along with no parabens, makes this an easier formula for sensitive users to trust.
Carrageenan, a seaweed extract, and guar conditioners are included for slickness and hydration. The result is a fuller, cushioning consistency that stays put rather than a fluid that runs. The 125ml bottle is a practical everyday size rather than a travel one.
How it is meant to be used
The thick gel texture is the point of this product. It offers a padded, cushioning feel and, because it does not run, it is easy to apply precisely. That makes it a comfortable choice for people who find thin lubricants disappear too quickly on contact.
The trade-off is inherent to all water-based lubricants: they are absorbed and evaporate over time, so you will need to reapply during a longer session. A small splash of water can revive it as it dries. It is not designed for use in the shower or bath, where water simply rinses it away.
Toy compatibility and clean-up
Being water-based, Tsunami is safe with all toy materials, including silicone. This is its biggest practical advantage over silicone lubricants, which can degrade silicone toys and should never be paired with them. If you own silicone toys, a water-based gel like this removes the guesswork.
Clean-up is straightforward. It is water-soluble, so it rinses off skin and toys with warm water, and it is non-staining, which makes it easy to live with on bedding.
How it compares
Against a standard thin water-based lubricant, Tsunami trades some spreadability for a more substantial, cushioning feel that holds its place. Against a silicone lubricant, it gives up longevity and water resistance but gains full toy compatibility and easier washing.
Within Sliquid's own range, this is the thick-gel option; the brand's thinner naturals formula suits those who prefer a lighter, more fluid glide. Choosing between them comes down to whether you want body or slickness.
The bottom line
Sliquid Tsunami is an easy recommendation for anyone who wants a cushioning water-based gel with a clean, glycerine-free formula and no worries about toy compatibility. Just go in knowing it is water-based, which means keeping it within reach for a top-up and skipping it in the shower.
Frequently asked questions
Can I use Tsunami with silicone toys?
Yes. It is water-based, which makes it safe with all toy materials, including silicone. Silicone lubricants, by contrast, can damage silicone toys, so a water-based gel is the safer pairing.
Is it suitable for sensitive skin?
The formula is glycerine free, paraben free, pH balanced and described as hypoallergenic, which makes it a sensible choice for people who react to glycerine or prefer a shorter ingredient list. As with any product, patch test first if you have known sensitivities.
Will it last through a long session?
Being water-based, it will gradually be absorbed and dry out, so you may need to reapply. A little water can help revive it as it dries. If you want longer-lasting glide without reapplying, a silicone lubricant lasts longer, provided your toys are silicone-safe.
Does it stain sheets?
The product is described as non-staining and washes away with warm water, so it should be easy to live with on bedding and skin.
Is it vegan?
Yes. It is 100 percent vegan, with its thickening and moisturising properties drawn from plant cellulose and seaweed extract rather than animal-derived ingredients.
