According to women’s health expert Dr. Jennifer Wider, “oil-based lubricants can destroy the integrity of latex condoms.” That includes anything with oil in it , such as lotion or petroleum ...
Since some topical microbicide formulations currently under development function as lubricants, such "dry sex" traditions may pose a barrier to the implementation of topical microbicidal programs. Recent data on product acceptability, however, show that many men and women enjoy using gels during sex that would contain a microbicidal drug. [34]
Hydroxyethyl cellulose can be one of the main ingredients in water-based personal lubricants. It is also a key ingredient in the formation of large bubbles as it possesses the ability to dissolve in water but also provide structural strength to the soap bubble. Among other similar chemicals, it is often used as slime (and gunge, in the UK).
Smegma (from Ancient Greek σμῆγμα, smêgma, 'soap') [1] is a combination of shed skin cells, skin oils, and moisture. It occurs in both male and female mammalian genitalia .

Tomato-based foods contain some of the highest amounts of lycopene. For instance, a ½ cup of tomato puree has over 27,000 micrograms of lycopene, while a cup of canned tomato juice contains ...
Vaginal dryness is the condition in which this lubrication is insufficient, and sometimes artificial lubricants are used to augment it. Without sufficient lubrication, sexual intercourse can be painful. The vaginal lining has no glands, and therefore the vagina must rely on other methods of lubrication.
Nonoxynol-9 is a common ingredient of most vaginal and anal lubricants due to its spermicidal properties. A 2004 study found that over a six-month period, the typical-use failure rates for five nonoxynol-9 vaginal contraceptives (film, suppository, and gels at three different concentrations) ranged from 10% to 20%.
Water loss through the skin is normally about 4–8 g/(m 2 ⋅h). A layer of petrolatum applied to normal skin can reduce that loss by 50–75% for several hours. [4] Oils naturally produced by the human body moisturize through this same mechanism. [2] Humectants are hydrophilic and absorb water. They absorb water from humid air (when >70% ...
