Effetto Mariposa Launches a Plant-Based Tire Sealant Made From Olives - Across the Pond Beaver

Sep 3, 2020
by Ed Spratt  

We often think of olives skewered on cocktail sticks at fancy parties or floating in James Bond's martinis but we'd never have imagined they were a potential ingredient for tire sealant. Effetto Mariposa is hoping to change that and has just launched the world's first plant-based tire sealant made from olive stones.

Effetto Mariposa has spent the last two years developing a potentially innovative product that goes beyond the normal claims biodegradability. The Vegetalex is made using a mixture of finely ground olive stones and cellulose fibers bound together by xanthan gum, creating a completely plant-based formula with no microplastics, rubber particles and aramid fibers which can be found in other sealants. These materials, despite holding claims of biodegradability, can stay in the environment for very long periods with the potential for large amounts of damage for the planet and its inhabitants.

While developing the sealant, Effetto Mariposa's two main aims were to create a product that would be better for the environment and to last longer than more traditional sealants. Effetto Mariposa currently claims its formula will fill holes & cuts up to 5mm in diameter and can last in a tire without being changed for over six months in normal conditions with a minimum lifespan of three months in hotter and drier conditions.

bigquotesBeing able to ‘forget’ about tyre sealant is the dream of tubeless tyre users. Especially those of us who don’t ride too often, wondering whether the sealant is still liquid inside our tyres (or not) is a worry that can spoil the pleasure of a ride. Effetto Mariposa


With the sealant being made entirely from plants and natural ingredients, it won't contain ammonia or other aggressive chemicals and is easier to clean up when it is spilt on other surfaces. It is also safe for people with natural rubber allergies. Effetto Mariposa says it can be cleaned with just a brush and soapy water even after it has dried and the sealant will work with CO2

Vegetalex is available now in 1000ml bottles for $30 / 25€, you can find out more here.

 This is awesome. More and more bike products need to move in this direction. Finding ways to clean up the manufacturing process, sourcing "clean" materials, and end-of-life processing (i.e. recycling, biodegradability) should all be considered in our industry to a higher degree than present. Kudos to effeto mariposa for working hard to make our favorite pastime a little more sustainable. I'll definitely be picking up this new sealant.

 @big-red: this sealant will be my next bottle, but chains are a tricky one... I spoke with a dumonde tech engineer about biodegradable lubes several years ago at interbike and by their analysis the reduced chain life nullified the environmental benefits.

 @big-red: I'm using muc-off's bio-lube dry and seems to be working great so far. Also using their bio-degradable grease. I've been a bike tech since the early '90's so I take apart my bikes frequently and so far the bio-degradable grease is holding up too. I'll keep going down this route so long as the bio-degradable stuff seems at or even just near the performance level of the petroleum products.

 Yeah It's cool they are "green" but shouldn't we be eating the olives or making olive oil?
  • 8 0
 @mtbmaniatv: Unlike turning sugar or corn into fuel for cars, I don't think this will upset the availability of food all that much. I don't know how much olives are wasted on the market, but otherwise they could use the waste olives. I talked some guys who created Fruitleather. They collect unsold mangos at the end of a market day. Never realized unsold fruit is being disposed of and obviously the market people have to pay for that. So with them now turning that into leather, they at least gave it some purpose.

Not sure what part of the olive Effetto is using here. I suppose in the creation of olive oil, there must be a good lot of waste. Maybe it is this residue which Effetto uses? Somehow I don't expect it to be the oil that should seal tires. If so, I don't want it anywhere near my brakes when it burps!
  • 8 0
 @mtbmaniatv: I would imagine that the companies that make olive oil have tons of pits that they need to dispose of... This is a perfect way to use waste material and put it to good use!

 @billreilly: @mtbmaniatv: It says in the article that they use the stones. I bet spain has a lot of them laying around Smile .

 @Mesmomesmo: well, I can't read, so good thing you informed me. That makes sense
  • 2 0
 @mtbmaniatv: seems they're only using the pits. Most olive commercially bought are pitted so seems like there not much of an impact. Unless theres already a huge olive pit industry that I didn't know about that will be affected....?

 @Mesmomesmo: worked on a power plant in southern Spain years back that used dried olive residue (post extraction of olive oil) as a fuel to fire a boiler that was powering a steam turbine. There was a whole reservoir of the waste material.

 Is there an extra virgin version for the dentists?
  • 3 2
 Extra virgin doesn't necessarily depend on the audience. It depends on the conditions. Extra virgin is strictly for cold conditions.
  • 20 2
 Dunno....after trying the much hyped Finish Line sealant and realizing it how much it sucked I’m hesitant to try anything non Stans or Orange.
  • 2 0
 Same here. That Finish Line stuff was the absolute worst purchase I have ever made. Don't they even test this stuff before selling it??

 Muc Off seemed to work pretty well. Going to try TruckerCo soon (local guy too).

 I use the original Caffelatex from Effetto Mariposa and it is as good if not better than Stan's.
  • 2 0
 @billreilly: Agreed, the Caffelatex is great, except for the short liquid lifespan (i had to top up every 4 weeks in summer.)
  • 3 0
 @JSTootell: I've been using the TruckerCo for a few years. Stan's always worked well, but the Orange Seal separated into a lump and oil within a few days in the Terlingua (desert, just like your Vegas home) heat. I tried the previous Mariposa and the Slime, neither worked very well. I was living in an area with lots of goatheads and mesquite thorns at the time, which was why I was looking for a lower cost alternative. TruckerCo hasn't let me down since 2016. It doesn't snot-ball very much, but will make a coating as it dries, just like Stans. I buy it by the gallon. I'll be trying their brake pads soon, because the sealant and valves have been decent to use.

 my big 3 is stans, orange, maripossa

 I'm unfortunately in the same boat, Stans or Orange for me as well. Nothing else seems to work half as well, and I'm not going to experiment with an oddball sealant that can end my ride miles from the car. Not worth it to me.
  • 1 1
 Has anyone tried Squirt sealant? I love their chain wax. I don't know why I deviate from Stans, I get burned every time I do... Maxima was the latest disappointment. I dig many of their other products, so I was hopeful, but it dried-out immediately.

 First plant based tire sealant? Then what about all the rest of tire sealants made of natural latex coming from rubber trees???

 Is processed latex rubber biodegradable?
  • 1 0
 @billreilly: good question. Based on the easy water clean-up I'd guess so but don't know for sure...
  • 1 0
 Latex is biodegradable, but takes time at least four years I think. Vulcanized rubber (tires) on the other hand not so mush.
  • 1 0
 I think most (if not all) latex sealants contain ammonia.
  • 1 0
 @kirat Yes you are right. The main difference is that rubber trees plantation cause deforestation all over south-east Asia mostly in Borneo.

 Next step: red wine suspension oils to pair with your olive tapenade tire sealant. I think the Pinot Noir pairs best

 I'm already using Effetto's balsamic reduction for clean-up and removing any residue.

 If it can easily be cleaned up with a brush and water after its dried, does that mean once its plugged a puncture in a tire, it'll come undone when crossing a creek or getting wet?

 During WWII they ran the piston engine'd fighters with peanut oil as a lube. Changed the oil after every extended flight it it was bio and being around the a/c smelled great. Don't see why a chain lube that doesn't take any heat to speak of wouldn't work. Just add jelly in increase the viscosity.
  • 3 1
 At the end of the day, I'll wear hemp baggies, ride a recycled aluminum frame with biodegradable grips, I'll go vegan and give up bacon... but unless this sealant works equally as well as Orange Seal or Stans then why would you ever compromise on something which is so critical to ensuring you can finish a ride?
  • 2 0
 caffelatex is as good as stans and orange, i assume this would be similar.
  • 1 0
 @RonSauce: No it doesn't, and there is no good data to support that assertion.
  • 1 0
 @nzandyb: I've used them all, and stay using caffelatex. I've had less problems with mariposa than I have with stans, both were given 3 seasons.

But I guess I could use you method of testing and just imagine stuff.

 Next they will make the Balsamic grease to go with the olive oil

 Can’t say that I ever Wondered if the sealant is still liquid in my tyres.

It goes in and what Ever’s left when I put on a new tyre comes out.
  • 1 3
 In emergency case out of fuel.. perhaps you can open the valve and drink it to make it home...
Now seriously good stuff cause never liked to touch this liquid with my hands... I allways felt it was really toxic and you kinda absorb it with your skin... So please make a 100% extra virgin for us! Wink

 A really good idea, hopefully it works better than caffelatex which never sealed and dried up super fast.

 In not sure I would call their unicorn ejaculant "sealant". It just decorated the inside of my tire with glitter, but did nothing to seal punctures
