Introduction: Personal Lubricant

Picture of Personal Lubricant

Cheap, easy to make personal lubricant. Start to finish is about 10 minutes without cooling time. I'm assuming this is water based, since all it is is water and corn starch. If you are allergic to water or corn starch, do not use. USE EXTERNALLY! Also, since the comments are talking about this being glue, YES, you can glue things together with this, but it is a VERY weak bond since the promintent ingredient is water. The proportions are not correct for making a glue, and it takes a while for this stuff to dry out. I glued two sheets of printer paper together with a tiny dot of the stuff, but I separated the sheets like they were not glued once it dried.

Step 1: Gather Materials

Picture of Gather Materials

1 cup (8 oz.) water

4 tsp corn starch (I do not suggest putting the corn starch in a container. It tends to stick to everything. For the purpose of this guide, it is shown in a small bowl)

A cooking pot

Step 2: Mix Water and Corn Starch in Pot

Picture of Mix Water and Corn Starch in Pot

Add the water and the corn starch into the pot and mix. I used a wood spoon to mix. I don't know if metal or plastic would make a difference.

Step 3: Slowly Bring to a Boil on Medium to Low Heat

Picture of Slowly Bring to a Boil on Medium to Low Heat

Make sure you have stirred well and there is no corn starch stuck to the bottom of the pot. Cover the pot and slowly bring to a boil. All stoves are different; I used "4", the setting directly across from the off setting. Stir often, making sure the corn starch does not stick to the bottom of the pot.

Step 4: Almost There...

Picture of Almost There...

The contents should do some funky things while being heated. Just remember to stir often and be patient.

Step 5: Once It Has Reached a Boil...

Picture of Once It Has Reached a Boil...

Once it has reached a boil the contents should become more viscous and somewhat resemble the consistency of gelatin. You cannot tell very well from the picture, but you will definately be able to tell when it is done. Remove from the stove and pour into a container of choice.

Step 6: Allow to Cool

Picture of Allow to Cool

Allow the solution to cool at room temperature. DO NOT PUT IT IN THE REFRIDGERATOR OR FREEZER!!! It will cause the solution to form a skin that is a lot harder than the rest.

Step 7: Enjoy!

Picture of Enjoy!

The container on the right is still hot and starting to cool. On the left is the finished product that has been stirred up to show texture. The finished product should jiggle like jello. My results have had a small layer of "skin" when it has cooled, but was easily removed with minimal effort.

I mad a quarter of the "recipe" in the microwave. Umm, it worked great...

EliE14 (author)2016-12-23

is this good for anal?

Kklopezgirl (author)2016-11-27

How long does it last? Ive made this lube and 2 days later it doesnt appear to look like any of the photos.

missing_instructions made it! (author)2016-05-18

Wish we knew this was possible a year ago before I handed Astroglide so much of my hard earned money. My girl made this tonight inside of 20 minutes after realizing we were out of lube. Feels great.

Jayden_Monkley (author)2015-08-04

I'm sorry Momma,
I was only tryna make lube,
I never meant to ruin your pot, but tonight
I'm cleanin' out my closet.

_diyMATT (author)2006-10-16

Joke 1) mmmm, personal lubricant. Joke 2) Why not just use some canola oil for your slippery needs. Joke 3) I like to make personal lube at home too. It typically invloves a willing female however. I don't think my instrucable would be allowed here

all_thumbs (author)_diyMATT2006-12-04

On #3: Please go ahead. I think a lot of the frequent instructable consumers would find it very, very interesting. I doubt you'd break any new records in internet indecency, and we are all grown up, aren't we?

DIY-Guy (author)all_thumbs2014-03-17

Begging your pardon, but KIDS do read these. Please keep it very clean and remove innuendos. Thank you.

Depending on how you define "grown up."

If you laugh at fart jokes, your not grown up.

not me

AshWilliams (author)2008-09-14

I want to try this because I'm too cheap to buy from a sex shop but will this ruin my Fleshlight at all? I mean, the Fleshlight site says to use only water based lubricants and like you said this is mostly water so I figure it might work but I want to hear what you have to say.

wupme (author)AshWilliams2008-09-16

Just look out for ultrasonografic gel. Those are waterbased, and are the exact same thing as the expensive lubricants you can buy. Its about 4-5 Euros (7-8Dollar) for 1 liter, of course larger bottles are way cheaper in the end. Only use waterbased stuff with a "Flashlight", never use oily stuff or silicon.

DaPaulness332 (author)wupme2008-09-16

he didn't mean 'flashlight' it's 'Fleshlite' its a sex toy

Phoghat (author)DaPaulness3322014-01-25

He could actually mean "flashlight". I've seen stranger things in the ER

wupme (author)DaPaulness3322008-09-16

Geez, you should read my text again. I'm talking about that sex toy, i just didn't want to name it here. But now i have to, because you forced me to. You're a bad person, you owe me an Ice Cream for that one.

freeza36 (author)wupme2012-04-12


publicity (author)AshWilliams2012-07-07

I think it is a water-based lube, since 95% of it is water. I also use it with all my sex toys, including the fleshlight and it works fine, no damage at all! In fact, it works even better than other expensive lubes I tried b4 ;p

vaultshadow (author)2012-08-08

it works for buttplugs?

kretzlord (author)vaultshadow2012-12-29

Favorite comment ever ^_^

kingneo (author)2012-08-04

i tried it with mixing up egg yalk less,it can work fine,idont know different ppl having different effects but its work fine for me

publicity (author)2012-07-07

Waw I can't believe this actually works!!!! THANKS MATE you just saved me a lot of $$$$$ !!!!!

I did use a bit more cornflour/cornstarch to make it slightly thicker, and I bottled it straight away, so I did not get any skin developing on the lube; so it's PERFECT!! It also lasts very long and it feels awesome! :D :D


PyroMaster007 (author)2009-05-06

Are you intending this to be used in a sexual way?

freeza36 (author)PyroMaster0072012-04-12

"Personal" lubrication. I think it is meant for a very special, eh, one person sexual activity.

IronManMC (author)2012-03-09

If your corn starch skins over, you're using too much starch. Cut the starch WAYYY back, use more sterile water, and cook it longer. The longer you cook it, the more the "stickies" stick together. A little vitamin E will help preserve it.

The slipperiest stuff I've ever tried is J-Lube. Google j-lube for a LOT more info, and farm supply places that sell it. Veterinarians use it to help calves out, and get their hands in the animals "business".

It's 25% some super molecule polymer and 75% some kind of sugar. It comes as a 10 oz squeeze bottle of dry powder. You don't need much. Three pinches will eliminate all friction in the known universe. You can sprinkle a *tiny* amount on "critical areas", then sprinkle or spray sterilized water on your junk, and slide right in. If she's completely clean (otherwise, it hurts), you can probably get away with it by telling her you're not "in" yet.

(Ladies, you ought to know by now that all men lie, always. Even this is a lie.)

You can also premix it. Sterilize everything (NOT the same as"neuter"). Then nuke it until it boils like Old Faithful on anabolic steroids. The microwave will require cleaning. Water and salt takes it right off. You can store this in the refrigerator for a week or two. I'm experimenting with preservatives. Vitamin E and just a little 91% alcohol kills all varmints I've exposed it to, but CAREFUL - alcohol also burns your junk! I have citric acid (AKA kosher salt), and am looking for a deal on bulk potassium sorbate.

feruruguay (author)2012-02-05

People: it is right to concern about contamination and bacterial grow.
All products made without preservatives woud be contaminated in a few days or hours.
So, the best is to prepare the lubricant shortly before use and discard the remanent. It is so cheap that it has nosense to keep it for long time

feruruguay (author)feruruguay2012-02-13

I've made a very simple personal lubricant for sexual intercourse and worked VERY well.
Just let a 1/5 teaspoon of Guar Gum to hidrate in 250 ml. of tap water. Shaked the bottle for a minute and let it stand. !0 minutes after that I shaked ir again and that was all.
A perfect lubricant for a ridiculous price. Compared to KY gel this is a a steal. Also, I could made such a quantity to soak all the body of my girl and mine for a very fun and exiting night.
The remaining gel was discarded.

kukulhora (author)feruruguay2012-02-20

Me and me woman named Nellie
Are adhered belly-to-belly.
Because sad to tell, we used Guar Gum gel
Instead of Petroleum jelly.

feruruguay (author)kukulhora2012-02-20

That`s so funny!!
Did you make it too hard? Or perhaps you let it dry after some hours. Since it is water based, evaporation of water would make the stuff more and more sticky.
Make the lubricant with plenty of water, it will function very well always

Petroleum gelly is not safe for condoms,

ArtsyFartsyGirl (author)2012-01-03

This is so funny! You people are so cheap! Buy some that's already made and save yourself the stress. I wouldn't let anyone make a batch of that for me! LOL!!!!! Making my skin crawl just thinking about it!

Goodhart (author)ArtsyFartsyGirl2012-01-07

It's NOT about being cheap, it's about the creative/maker spirit.

_doug_ (author)2011-10-30

Thanks folks for all your contributions!

Just tried this recipe ( along with this self-made toy: Wow, what a joy! 8-))

You don't need to boil the water for long, just a few seconds will do.

I'll try xanthan and maybe xylitol later, and I will report back if I remember.

Btw, I also tried this, but with little success: The consistency was a little too friable/crumbly; maybe I'll try again later.

_doug_ (author)_doug_2011-11-09

OK, meanwhile I got hold of some xanthan. (In Germany you can buy it for 3,40 EUR or so per 30 g at "Natuerlich Provence", which is the successor of "Spinnrad". Pharmacies don't seem to be allowed to sell xanthan any longer, and anyway it used to be more expensive there.)

It really works great, xanthan and water make for a superb lubricant! There was only one minor issue: It was not easy to dissolve the xanthan entirely, but maybe I took a bit too much of it for the given amount of water.

Metamorphisis (author)2011-07-24

"Funky" eh? It burned like nuts when i was stirring the thing, and it reaches boiling then it goes foamy to the top like a volcano, i'm not sure if i am supposed to stir it when its boiling with the foam coming out of it or what, this tutorial is really starting to tick me off! :(

Metamorphisis (author)2011-07-24

Stir for how long??

Metamorphisis (author)2011-07-20

I am soooooo trying this, when my mom's gone to store or whatever. being 25 and having a hella-nice sex toy is easier than a girlfriend nowadays (personal experiences) I'm going to try this and see how it goes, thanks for the recipe! I'll edit this later to give my comments.

digitalia (author)2011-07-05

Still, there's nothing better (or cheaper) than good ol xantham gum and water. If you're concerned about bacteria, just make it up fresh. A pinch of xantham, and some water. Slickest stuff you ever used. And it's vegan!

gammaray007 (author)2009-07-24

@mngarrison-- Personal lube *is* expensive when you need a couple of gallons, which is what is required for a really juicy "body slide" session, or the kind of body massage that is a part of the Japanese "soapland" experience. If anybody knows that secret formula, please post it!

digitalia (author)gammaray0072009-09-04

Well, I just happen to have the answer for you. The slipperiest stuff on earth is made from a weak saline solution (water with a little salt in it) and a small amount of powdered soluble fiber, such as guar or xanthan gum. Xanthan is quite a bit better, and it dissolves to a completely clear gel. (Don't let the word 'gum' throw you, it's just what they call soluble vegetable fiber.) Experiment with proportions -- you'll know what feels good -- but start with sifting together 1/2 tsp table salt with 1/2 tsp powdered xanthan, then whisk in about 1 cup of water, just a tablespoon or two at a time at first to avoid lumps, or use a blender and just throw it all in at once. Bonus: The saline solution is pretty much the same saltiness as saliva, so there's no sting -- and it works as a preservative to keep your lube tasty (oh, yeah, you can eat this stuff; it's actually good for you).

pinwheel007 (author)digitalia2009-09-24

okay so to be sure.. is this stuff vagina friendly?

cutopia (author)pinwheel0072011-07-05

Xanthan gum is actually the main ingredient in at least one store bought lube. Another I saw was using essentially very finely powdered cotton. Another seemed to be based on aloe vera thickened with a little bit of methylcellulose.
Meanwhile, I have heard the Japanese used yamaimo (the mountain yam) historically for lube.

digitalia (author)pinwheel0072009-09-24

The pH and salinity should be fine for vaginal use. The gums are completely natural and are sold as food products, but they could potentially lead to microbial growth (i.e., yeast infection), except for the xylitol, which is a microbial inhibitor. (And I would start with sterile water, of course.) All in all, it should work well vaginally or elsewhere. That said, I am not a professional pharmaceutical chemist or clinician... consult somebody like that that for a competent opinion. One caution: don't try to store it in your glovebox for six months and then expect it to be good -- it is a natural product and susceptible to spoilage.

wonsnot (author)digitalia2010-07-03

I think that this comment is better than the instructable listed on this page, and that it should be made into an instructable itself. Because everything is made better with pictures.

digitalia (author)digitalia2009-09-04

Oh, yeah, one more thing... If you are concerned about yeast infection, just dissolve a little xylitol in the water before you make the gel. Xylitol is actually a naturally low-calorie sweetener (like sorbitol), but it has the added bonus of retarding microbial growth. That's why they add it to some toothpastes. And it kills yeast, too, without side effects. And it makes the lube sweet to the taste! You can get it at most health food stores in the sweeteners section (but not at Whole Foods, which has a strangely unscientific policy against processed sweeteners, even though xylitol is made from corn and occurs naturally in such foods as berries and grains).

thebigbird (author)2011-04-05

I have a question. Won't [harmful] microorganisms grow in that concoction if stored at room temperature? I mean you've got water there. and corn starch. Isn't it conducive to life?

cutopia (author)thebigbird2011-07-05

Things like water mold can grow in that.
Sex parts are not even remotely free of microorganisms, however, so within reason microbes in the lube wouldn't necessarily cause any problem (because the body is equipped to handle such things).
I do wonder, however, if this recipe could benefit from a few drops of apple cider vinegar or something else to make it slightly acidic like a natural vagina.

cutopia (author)2011-07-05

From what I've been seeing of this issue on the internet, people seem WAY too worried about getting infected.
The vagina is designed to be able to accept a guy's penis... and as we all know, guys' penises tend to not be as clean as one might like. Yet, healthy women generally don't get infected from having sex.
A small amount of a flavor would probably be fine, but to be safe, avoid ones that are alcohol-based since alcohol apparently can be drying or stinging up there and also could disrupt any natural bacteria inside the vagina that help protect from yeast.
Also, peppermint oil shows up in many store-bought lubricants, but some people find the sensations it causes too strong.
