What are Essential
Oils?
An essential oil is
described as a volatile material derived by a physical process from an odorous
plant material of a single botanical species.
Where
do they come from?
Essential oils occur
in the plant kingdom in flowers, leaves, roots, stems, bark and fruit. Often a plant that produces an essential oil
may do so in only one part, such as jasmine from the flowers. Others, like the bitter orange tree, produce
three different essential oils: petitgrain from the leaves, neroli from the
flowers and bitter orange from the fruit.
What are they
used for?
Often the use of
essential oils is associated with aromatherapy. However, this accounts for only
about 5% of essential oils produced in the world.
The primary users
are:
|
* The food industry
for flavoring * The cosmetic industry for perfume, skin care and personal
care * The pharmaceutical industry * Chemical
manufacturing
|
What are their main functions?
Each oil is unique
in its chemical structure. Some, like the rose, have over 200 chemical
compounds. The essential oil is a
byproduct that is produced through the metabolism of the plant. Its functions are to attract pollinating
insects, prevent damage from animals, act as a cooling mechanism and to protect
against viral attack.
How
do they work for us?
All pure
unadulterated essential oils have one common property: they are all
antiseptic. From that point, each oil
offers a variety of unique properties such as being an analgesic,
anti-inflammatory, antidepressant, antispasmodic, aphrodisiac, bactericide,
carminative, cicatrisant, cytophylactic, deodorant, digestive, diuretic,
emmenagogue, emollient, expectorant, fungicide, germicidal, hypertensive,
hypnotic, hypotensive, insecticide, mucolytic, nervine, relaxant, rubefacient
sedative, soporific, stimulant, sudorific, vasoconstrictor, vasodilator and
vulnerary.
Are all essential oils
organic?
Basically yes, they
are organic in chemical structure. However, the plants that essential oils are
derived from are not necessarily grown organically or pesticide free. The oil must be “certified organic” by one of
the governing soil associations, deemed to be grown in organic soil and
pesticide free. This certification takes
place every year - soil and plant material must be tested.
What Exactly Is a
Vegetable Oil?
All vegetable oils
are defined as lipids and are mainly composed of fatty acids. Fatty acids are the major building blocks of
fat in human bodies and foods and are important sources of energy for the
body. They are also important in the
building and maintenance of healthy cells.
Saturated Fatty
Acids
Saturated fatty acids are
mostly of animal origin such as red meat and dairy products and tend to be solid
at room temperature. (e.g. lard, butter,
cheese). The three most common saturated fats in food are myristic, palmitic and
stearic acids.
Unsaturated Fatty
Acids
Physically these acids are
liquid at room temperature. They are
found in olive oil (mono) and
safflower seed, sunflower seed, sesame, soybean, wheatgerm and corn (poly). They
contain linoleic, linolenic and arachidonic acids which are collectively known
as essential fatty acids because they are essential to life. None of these are
produced by the body and must be obtained from outside
sources.
Linoleic Acid and Omega-6
Gamma linolenic acid (GLA)
and dihomogamma-linolenic acid (DGLA) are called the Omega-6 fatty acids.
Linoleic acid is the main omega-6 polyunsaturated fatty acid and is found in
most cold pressed vegetable oils. A deficiency of linoleic acid can lead to
eczema-like skin eruptions, loss of hair, excessive sweating with thirst,
susceptibility to infections, poor wound healing, arthritis, and heat and
circulatory problems.
Linolenic Acid and Omega-3
Alpha linolenic acid is
found in high concentrations in vegetable oils such as linseed and canola. When it is metabolized in the body, linolenic
acid forms a number of members of the omega-3 fatty acid family. A deficiency of linolenic acid is known to
cause muscular weakness, lack of co-ordination, tingling of arms and legs,
disturbances of vision and behavioural changes.
I noticed that some of your products contain vegetable wax. Is this dangerous?
The vegetable wax used in our products is a natural wax derived from palm and coconut oil. It contains no other ingredients. Sometimes vegetable waxes are referred to as Lanette wax. One form of Lanette wax (Lanette S) contains SLS (Sodium Lauryl Sulphate). We have never used this form of Lanette wax.
What is GeoGard Ultra?
Geogard® Ultra (INCI name: Gluconolactone and sodium benzoate) is a natural
preservative that has been designed to offer broad spectrum protection in
personal care and cosmetic formulations. It consists of a naturally occurring
food additive (glucono delta lactone,) derived from corn, and a food grade
preservative (sodium benzoate, the sodium salt of benzoic acid) along with a
trace amount of calcium gluconate as a processing agent. Geogard® Ultra is
accepted by ECOCERT as a preservative in certified organic cosmetics. The
gluconolactone component is used in the food and cosmetic industry as a
moisturizer, antioxidant and chelant. Gluconolactone is not derived from
genetically-modified crops. The microorganisms used in the fermentation process
are not genetically modified.
This natural preservative is globally approved at formulations of 2% (which would result in only 0.495% sodium benzoate). We use 1.0% to 1.1% Geogard® Ultra in all of our formulations that require a preservative.
