Bests & Worsts Reviews from Amazon

Powdered personal lubricants are mixed to preference. They are very slick and great for butt stuff. Same key ingredient as Bad-Dragon's lubricants, but mixing it yourself is much more economical & you can control how thick/gooey it is. I recently switched to X-Lube (100% polyethylene oxide) because I discovered that J-Lube is only 25% polyethylene oxide and 75% powdered sugar (more detail below), so I will be mostly comparing the two in this review. X-Lube requires far less powder than J-Lube to mix a bottle of the same consistency. One level cap of X-Lube powder added to 250ml/8oz of water makes a wonderfully slick and gooey-thick lube (maybe too thick, as it still performs very well even with almost twice that amount of water!). One level X-Lube cap measures out to be 1/2 tablespoon. X-Lube powder is about as granular as laundry detergent. Easier to handle & less messy than J-Lube, which is a very fine powder and prone to going airborne while handling. X-Lube dissolves much better and more evenly than J-Lube does. No clumps! The resulting lube is also much more clear. It takes about 20 minutes to set, but the bottle recommends waiting 2 hours before using. Note: Adding more powder or water to adjust the consistency of lube that has already been set will take a couple days before it is uniformly redistributed. It is best to know your preferred measurements of powder and water for the initial mixing. As with ANY water-based personal lubricant: if surfaces dry out during use, you can rejuvenate the slipperiness by splashing it with a very small amount of water. I figure the lack of sugar in X-Lube makes it much safer for vaginal use than J-Lube. (I'm a dude, so I wouldn't entirely know.) Ease of cleanup likely depends on concentration of mix. I mix it somewhat on the thick side, and it washes away with just water. For my intents are purposes, X-Lube completely replaces J-Lube. I intend on comparing X-Lube to K-Lube later. K-Lube boasts added preservatives-- but J-Lube is 75% sugar, and I've never had any major issues with shelf-lives of a couple months at a time (aside from when a small group of ants found the prepared J-Lube bottle, which is what prompted me to look into exactly what J-Lube was made of). Considering that X-Lube is 100% poly-oxide, I don't think I will have any issues with storing prepared X-Lube for extended periods of time (though the bottle suggests using within 1-2 weeks). UPDATE: initial impression of K-Lube compared to X-Lube. UPDATE2: https://www.amazon.com/gp/customer-reviews/RW8COCVPHN1B1 K-Lube powder is a lot like X-Lube, a detergent-like powder. Not a fine dust that makes a mess like J-Lube. Flip-top bottle is convenient for measuring because pouring is more controlled. For the same powder/water ratio, K seems more sticky & slick than X, but not as viscous (which I think is a good thing). But it largely seems like they are pretty much identical. X costs $32 for 100g. 100% polyethylene oxide. K costs $35 for 200g. Blend of poly-oxide and other undisclosed ingredients. Based on how they compare, I am sure K-Lube is still comprised of mostly polyethylene oxide (90%+). Just a few bucks more for TWICE the product! I assume the undisclosed additives of K-Lube are to improve the shelf life. Based on Bad-Dragon's lubricant, these are likely Potassium Sorbate (preservative) and Citric Acid (pH adjustment required for the preservative to work). But I don't mind not knowing, as long as there is no SUGAR like there is in J-Lube. For more context, I'm going to copy & paste most of my review for J-Lube here: https://www.amazon.com/gp/customer-reviews/R3E5KY30CHWT8A _ Some praise J-Lube over X-Lube or K-Lube as a personal lubricant because "you get twice the product for half the cost" without realizing that J-Lube is mostly a dispersing agent (helps spread main ingredient around more evenly for applications in powdered form). Google "J-Lube MSDS" and see that it is 75% sugar (powdered sucrose). At least two references are readily available. The key ingredient of powdered personal lubricants is polyethylene oxide. J-Lube 10oz bottle only contains 2.5oz polyethylene oxide. The rest is filler. X-Lube 3.5oz bottle is 100% polyethylene oxide. K-Lube 7oz bottle is an undisclosed ratio of polyethylene oxide and other ingredients (likely preservatives). X-Lube and K-Lube offer the same mix-to-your-preference lube with far less filler. Keep in mind that they cost more because they contain a higher concentration of the more-expensive ingredient. That means they use less powder than J-Lube to mix the same amount/thickness of lube, so their smaller bottles will last just as long (or longer!).
