Personal lubricants (colloquially termed lube) are specialized lubricants used during human sexual activity to reduce friction between body parts, or between body parts and other objects. They are used during sexual acts such as intercourse and masturbation, to reduce friction to or between the penis and vagina, anus, or other body parts, or applied to sex toys to reduce friction or ease in penetration. Surgical or medical lubricants or gels, which are similar but not usually referred to or labelled as "personal" lubricants, may be used for medical purposes such as speculum insertion or introduction of a catheter.
Petroleum products are useful materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure chemical compounds, petroleum products are complex mixtures. The majority of petroleum is converted to petroleum products, which includes several classes of fuels.
According to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as "energy carriers", i.e. various grades of fuel oil and gasoline. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Since petroleum often contains a few percent sulfur-containing molecules, elemental sulfur is also often produced as a petroleum product. Carbon, in the form of petroleum coke, and hydrogen may also be produced as petroleum products. The hydrogen produced is often used as an intermediate product for other oil refinery processes such as hydrocracking and hydrodesulfurization.
K-Y Jelly is a water-based, water-soluble personal lubricant produced by Johnson & Johnson. According to the company, "The origins of the brand name 'K-Y' are unknown. Two popular hypotheses are that it was created in Kentucky, hence 'K-Y', or that the letters represent the key ingredients used to make the lubricant, neither of which is proven." Historically the main ingredient is methyl cellulose with carboxymethyl cellulose as a constituent ingredient.
Introduced in January 1904 by pharmaceutical and suture maker Van Horn & Sawtell of New York City, and later acquired by Johnson & Johnson, K-Y Jelly's original stated purpose was as a surgical lubricant, and it was often chosen by doctors because of its natural base. Johnson & Johnson produced a sterile version of the product (intended for medical markets) and a non-sterile version (marketed as general-use personal lubricant) until 2004, when it discontinued the sterile line.]citation needed[ The product is now more widely used as a sexual lubricant. It does not react with latex condoms or silicone rubber-based sex toys. While K-Y has a thick consistency and a tendency to dry out during use, it can be "reactivated" by the addition of saliva or more water. K-Y Jelly does not contain a spermicide. A formulation with nonoxynol-9 was available, but Johnson & Johnson removed it from the market after finding that it could facilitate HIV spread.
Petroleum jelly, petrolatum, white petrolatum, soft paraffin or multi-hydrocarbon, CAS number 8009-03-8, is a semi-solid mixture of hydrocarbons (with carbon numbers mainly higher than 25), originally promoted as a topical ointment for its healing properties.
After petroleum jelly became a medicine chest staple, consumers began to use it for myriad ailments and cosmetic purposes, including toenail fungus, male genital rashes (non-STD), nosebleeds, diaper rash, and chest colds. Its folkloric medicinal value as a "cure-all" has since been limited by better scientific understanding of appropriate and inappropriate uses (see uses below). It is recognized by the U.S. Food and Drug Administration (FDA) as an approved over-the-counter (OTC) skin protectant, and remains widely used in cosmetic skin care.
Materials science, also commonly known as materials engineering, is an interdisciplinary field applying the properties of matter to various areas of science and engineering. This relatively new scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties. It incorporates elements of applied physics and chemistry. With significant media attention focused on Nano science and nanotechnology in recent years, materials science is becoming more widely known as a specific field of science and engineering. It is an important part of forensic engineering (Forensic engineering is the investigation of materials, products, structures or components that fail or do not operate or function as intended, causing personal injury or damage to property.) and failure analysis, the latter being the key to understanding, for example, the cause of various aviation accidents. Many of the most pressing scientific problems that are currently faced today are due to the limitations of the materials that are currently available and, as a result, breakthroughs in this field are likely to have a significant impact on the future of technology.
Wet Lubricants is a brand of personal lubricants produced by Wet International, part of Trigg Laboratories in Valencia, California. The line includes a variety of water based, silicone based and oil based lubricants, as well as massage oils and shaving creams.
The Chief executive officer and President of Trigg Laboratories is Michael Trigg, who co-founded the company in 1989 with Executive Vice President Christian Franco. They started off with one product: Wet brand personal lubricant.
