Lube 101: Water-based Water-based personal lubricants are water soluble, and are generally the type which is least irritating to body surfaces. These are descended from a cellulose and water combination, originally labeled as 'Surgilube', released in the 1950s. Subsequent products have added various agents for spreading, water retention, and resistance to contamination. The viscosity of these products can adjusted by adjusting their water content and concentration of cellulose (or other gel forming macromolecule). They do have a tendency to dry out during use, but application of additional water is sufficient to re-activate them. These properties lead to their frequent use for sexual activity. Since the 1980s, a few companies have used a water soluble, silicon co-polymer (dimethicone), for a prolonged slippery effect. While these contain a silicone component they are still water based products. They are very slippery, which can be a disadvantage because a certain amount of friction is necessary for optimal sensation, their viscosity cannot be adjusted, and they can stain clothing and sheets. Water-based lubricants are incompatible with sex acts which occur in water (such as in a bath) as they can be dissolved or dispersed in water. Popular brands include K-Y Jelly and Astroglide. [edit] Oil-based Petroleum jelly has long been used for medical procedures. Being oil-based, it does not react with body fluids in the same way as water-based products, making it longer lasting, though it is somewhat less lubricating. Petroleum jelly is sometimes used as a lubricant for anal sex. Although petroleum jelly is inexpensive and readily available, it can often be very difficult to clean off the body after sexual activity, due to the fact that it is not water soluble. Unlike water-based lubricants, oil-based lubricants weaken latex and may reduce the effectiveness of latex condoms as a contraceptive and protection against sexually-transmitted diseases. This also applies to oil-based lotions or foods which may be used as an improvised lubricant. It has been said that no oil-based lubricants should be used for anal sex or masturbation because "many oil-based sub-stances will coat the lining of the rectum, providing a haven for many potential infections." ([1]). Popular brands include Vaseline and Crisco. [edit] Silicone-based Technically, most silicone-based lubricants are oils, as they are chemically hydrophobic. They tend to retain lubrication longer than water-based lubricants. Silicone-based lubricants should not be used with silicone based sex toys. Popular brands include Eros, Wet Platinum and DeGLOW ([2]). [edit] Specialty "Specialty" lubricants are designed to cause physiological or physical changes to the area applied; these include warming lubricants which heat up in temperature on contact with the body. Breathing on these types of lubricants can also increase their temperature creating a pleasant warming sensation. Another type of specialty lubricant can increase blood flow to the regions in which they are applied creating a fuller erection of the penis or clitoris. Still others include flavored lubricants. Popular brands include Wet fun flavors (warming), KY Jelly (warming) and Thermal (warming & (blood flow vasodilator (l-arginine)). List of vasodilating and or sensitivity maximizing ingredients to look for: Methyl Salicylate,Niacin,L-Arginine HCL, Methyl Nicotinate, acetylcholine, amrinone, bamethan sulphate, bencyclane fumarate, benfurodil hemisuccinate, benzyl nicotinate, buflomedil hydrochloride, buphenine hydrochloride, butalamine hydrochloride, cetiedil citrate, ciclonicate, cinepazide maleate, cyclandelate, di-isopropylammonium dichloroacetate, ethyl nicotinate, hepronicate, hexyl nicotinate, ifenprodil tartrate, inositol nicotinate, isoxsuprine hydrochloride, kallidinogenase, methyl nicotinate, methyl salicylate, naftidrofuryl oxalate, nicametate citrate, niceritrol, nicoboxil, nicofuranose, nicotinyl alcohol, nicotinyl alcohol tartrate, nitric oxide, nonivamide, oxpentifylline, papaverine, papaveroline, pentifylline, peroxynitrite, pinacidil, pipratecol, propentofyltine, raubasine, suloctidil, teasuprine, thymoxamine hydrochloride, xanthinol nicotinate, diazoxide, hydralazine, minoxidil and sodium nitroprusside The #1 difference between silicon lubes is the viscosity. Any good sex shop will have testers so play with it for about 15 mins before you decide on the wrist or inner elbow. Got lube? will answer a lot of questions about what lube for what situation and how water based can irritate. Here's one paragraph to tease you: In researching lubricant ingredients, propylene glycol had the most inflammatory online reputation. It also had the most information available on toxnet. Reading the whole story is imperative. Propylene glycol isn't just used in cosmetics and pharmaceuticals, though it's used as an emollient (a thickening agent) and a preservative within these. It is also used in several industrial applications within paint and as a de-icing fluid. While it may cause contact allergy, it has also been used to hydrate and soften skin for burn victims. It has been studied extensively and found to have no effect on fertility and reproduction, unlike most other ingredients that may work to hinder sperm. For more info on the silicons see Got lube part two This is an interesting paragraph: Dimethicone, dimethiconal and cyclomenthicone are silicone liquids-combined together they become silicone lubricant. The primary difference between these three ingredients and all the water-based chemicals (such as glycerin, parabens, propylene glycol, sorbitol, etc.) is that all the silicone is basically inert. There are no topical body reactions to pure silicone lube. There are no irritations, no allergens and no microbes that can attach to the molecules and grow bacteria. I have a bottle of eros, astroglide, ky warming and some flavored bullshit that was on sale in a pretty bottle. The eros is my fave overall but the slickery sensation when left in certain places irritates me. I want to wash it alllll off. Astroglide is now carried at WMart so it's easy to access without going to an adult 'novelty' store. Olive oil, crisco and ye olde butter might do in a pinch, but i don't advise it, especially the latter of the 3. If you invest in one of the silicones the next time you're traveling, you'll have it for quite a long time and it shouldn't go bad. I also like the uberlube that comes with built in pump to keep it even 'purer'!
