Ethoxydiglycol

Ethoxydiglycol also known as diethylene glycol monethyl ether.  This product is a commonly used solvent used in lubricants and the cosmetic industry.  Ethoxydiglycol is used to dilute and thin out liquids that may be of thicker consistency.  It’s found in a lot of personal care products, including make-up, bath soaps, and skin-care products. It does have ether in it, which is considered a carcinogen, and can cause some people to have allergic reactions.

Essential Oils

Distilled oils taken from an herb, fruit, or plant. Essential oils are often used in aromatherapy and perfumery, and they are also known as volatile oils.

When used in lubricants, essential oils will not necessarily damage latex condoms, although this depends on the formula of the product. Most sexual health products that use essential oils use a fairly low concentration, limiting the chances of a negative reaction or skin irritation. However, people who are allergic to a certain plant will also be allergic to that plant’s essential oil.

Eclipta Prostrata

A plant commonly used in traditional Indian medicine. It is also known as false daisy.

Eclipta prostrata is sometimes used to treat hypertension, and it is said to relax the user. This also makes it a useful analgesic.

Some studies show that the plant could promote hair growth; it is being researched as a possible treatment for baldness, but the mechanism of action is currently unknown. While eclipta prostrata is generally seen as a safe ingredient, more research needs to be completed to determine whether it has any side effects.

Eucalyptus

Typically refers to the oils and dried leaves of the eucalyptus tree, which are commonly used in food and in traditional medicine. Eucalyptus is said to fight infection, improve energy, and regulate blood sugar.

While there is not much scientific research addressing these claims, eucalyptus is a popular ingredient in sexual health supplements. It has a pleasant flavor and aroma, and it is completely safe in small amounts. However, in large amounts, it can cause potentially serious side effects including nausea and vomiting. People with liver conditions should check with their physicians before using supplements with eucalyptus.

Emulsifier

A substance used to blend two liquids that would not otherwise mix due to differences in their chemical compositions.

Emulsifiers play an important role in many personal lubricant formulas. They work by altering the lubricant’s chemical kinetics, allowing opposing substances to work together – for instance, water and oil – and preventing those substances from separating.

Common emulsifiers include methyl cellulose, cetyl alcohol, methosulfate, and hydroxypropyl cellulose.

Erection

Typically refers to the most notable sign of male sexual arousal: the soft tissues of the penis fill with blood, causing the penis to grow substantially in size and become firmer. This allows the man to engage in intercourse and other sexual acts.

While erections are often associated with arousal, men can achieve erections without arousal, and aroused men may have trouble achieving erections for a variety of reasons. Some lubricant ingredients are included to help men create or sustain their erections (see “”erectile dysfunction”” for more information).

The female clitoris also fills with blood during arousal, which often causes the clitoris to protrude from the clitoral hood. While this is physiologically similar to a male erection, the term “”erection”” almost always refers to the penis.

Erogenous Zones

Any part of the body with heightened sensitivity that can cause or contribute to sexual arousal. The penis and the vagina are the two most obvious examples of erogenous zones, but the term can also apply to specific parts of the genitals that are more sensitive than others (the head of the penis, for example, or the clitoris).

The term is fairly subjective, and the nipples, ears, feet, and mouth can be considered erogenous zones for some people. Many personal lubricants have stimulating ingredients that can cause sensations or enhance nerve receptivity in erogenous zones (see “”stimulating lubes”” for more information).

Erectile Dysfunction

An inability to achieve or sustain an erection during sexual activity. Erectile dysfunction is a fairly common condition in men of all ages.

Men may have trouble developing and maintaining erections for a number of reasons. Stress, depression, and anxiety can cause erectile dysfunction, and physical conditions that restrict blood flow can also have an effect. Many medications can cause temporary erectile dysfunction. It is important to note that the ability to maintain an erection is not always related to sex drive.

There are a number of effective treatments for the condition, including pharmaceuticals such as sildenafil (Viagra), sexual therapy, physical therapy, and stress management therapy.

Ejaculation

A biological process that follows orgasm. Semen is ejected from the penis during ejaculation. The primary biological purpose of ejaculation is impregnation, although the amount of sperm and semen in each ejaculation varies depending on a number of factors.

Many sexually transmitted infections (STIs) can be transmitted during (or prior to) ejaculation, and in order to avoid STIs and pregnancy, men can wear condoms to prevent direct contact with their partners. It is important to use condoms correctly and to withdraw immediately after ejaculation.
