Ester
C (Vitamin C)
Ascorbic acid:
In most animals, the water soluble nutrient, ascorbic acid, is
synthesised from glucose. In humans a genetic lesion prevents us
from making it and diet is the sole source of this vitamin. As a
cofactor for many enzyme systems, ascorbic acid is involved in the
synthesis of collagen, carnitine, endocrine hormones, and
neurotransmitters. Many of the symptoms of the vitamin C deficiency
disease scurvy can be attributed to weakened collagen structures,
including bruising, muscle weakness, gum deterioration, and poor
wound healing.
Ester-C is created by
linking ascorbic acid with a mineral such as calcium, potassium, or
zinc. This form of vitamin C is non-acidic, which means it is much
better absorbed and provides the additional benefits of calcium
supplementation. The body does not make vitamin C, so it must be
taken in through diet. Benefits of Vitamin C supplementation include
immune system support, adrenal function, autism support, collagen
formation for healthy skin, and cardiovascular health.
ESTER-C:
The body changes vitamin C into numerous metabolites that may have
physiological actions that are different from those of vitamin C
itself. And these metabolites - whether manufactured in the body or
ingested along with supplemental vitamin C - may influence how the
vitamin itself is transported and utilized. The level of these
metabolites in the body may not rise significantly, however, until
very large doses of vitamin C are ingested. Laboratory studies have
shown that suggested the mechanism by which C metabolites,
especially threonate, might cause increased blood levels of vitamin
C. Dr. Anthony Verlangieri at the University of Mississippi used
isolated cells in culture to model how vitamin C is utilized by
various body tissues. They observed that exposing cells to calcium
threonate increased the uptake of ascorbic acid by these cells.
Ester-C Topical is a liquid concentrate containing patented Ester-C®
mineral ascorbates with C metabolites, dissolved in a specially
formulated blend of polyglycols. It retains superior stability in
oil/water emulsions typical of cosmetic formulations. It is also
non-acidic, free of chemical derivatives and effectively penetrates
deep down into the skin’s layers to help produce collagen and other
support structures.
Ester-C Topical Concentrate Awarded Patent:
Ester-C Topical's unique competitive advantage lies in its
stability, pH neutrality, and its ability to penetrate deep down
into the skin to help produce collagen and other support structures
without the use of chemical esters, such as ascorbyl palmitate or
phosphate. By contrast, ordinary vitamin C is acidic and may
irritate the skin. Vitamin C is also prone to oxidation and
decomposition because it is unstable in water, a component of most
cosmetic and skin care products.
A long-awaited breakthrough in the personal care industry, Ester-C
Topical has been successfully launched in a growing array of popular
skin creams and lotions.Toothpaste makers have also discovered the
value of adding stable Ester-C Concentrate to their formulations.
line of oral health care products includes an Ester-C toothpaste and
mouthwash, and Levlad Laboratories has launched a natural toothpaste
with Ester-C Dental Grade Concentrate.
The new patent distinguishes and protects Ester-C Topical
Concentrate in several ways: The "liquid compositions" covered by
the patent are non-acidic and contain two principal components -- a
mineral ascorbate and a pharmacologically acceptable liquid organic
polyol solvent. The mineral ascorbate can be any of the compounds
that Inter-Cal sells under the Ester-C label, such as calcium
ascorbate, zinc ascorbate, etc. The organic polyol solvents are well
known and widely used in cosmetics and pharmaceuticals. The patent
protects all "liquid compositions" that contain vitamin C
metabolites.
Ester-C is a patented, non-acidic form of vitamin C. Ester-C
Complex is the most advanced form of vitamin C available. Ester-C®
has a neutral pH that helps protect you from the stomach upset that
can accompany other vitamin C products.
Ester-C is different from ordinary or buffered vitamin C because it
is processed in purified water instead of solvents which makes it a
purer form of vitamin C. It contains calcium threonate, making this
form of vitamin C four times more bioavailable than other forms of
vitamin C.
Vitamin C is an important antioxidant and free radical scavenger.
Free radicals are incomplete atoms or molecules that are the natural
by-products of everyday metabolic, detoxification, and immune system
processes. These unstable compounds attack nearby molecules in an
attempt to become complete. Antioxidants like vitamin C are the
body’s natural defense system against free radicals. Antioxidants
are molecules that can safely neutralize these harmful substances
helping to promote cell health and support against cellular damage
that could lead to disease.
In addition Vitamin C also plays important roles in helping to
protect HDL cholesterol, or “good cholesterol” from free radical
damage. Healthy amounts of HDL have been shown to produce
cardiovascular benefits and promote heart health.
This is proven by scientists at Inter-cal who pioneered laboratory
and analytical methods to gauge the stability of Vitamin C liquids,
topical and cosmetics. Extensive accelerated test revealed the
remarkable long shelf life of Ester C topicals and the surprisingly
short shelf life of ordinary Victamin C. Please see chart below:
At present, the weight of evidence concerning the bioavailability
of Ester-C seems to indicate it is different from that of normal
vitamin C. It appears to benefit from the presence of the threonate
and other vitamin C metabolites which help improve its absorption
and tissue uptake. Dr. Verlangieri's work on the influence of
threonate on the absorption of vitamin C metabolite which is present
in Ester-C enhances absorption.
Finallly, Vitamin C supplementation has been shown to promote
capillary health, maintain healthy collagen, provide increased
antioxidant protection and immunity, enhance normal development and
maintenance of bones, cartilage and teeth, promote wound healing and
provide vital support to amino acid function within the body.
What is the difference between Ester C and other vitamin C?
Ester C increases white blood cell ascorbate levels 4 times more, is
better absorbed, and is faster absorbed than other types of vitamin
C. Ester C circulates in the blood stream twice as long and is
excreted into the urine at a lower rate. It is also less likely to
create gastrointestinal discomfort.
Ester-C is a patented, non-acidic form of vitamin C in a complex
containing an essential mineral. The complex also contains
metabolites of vitamin C that have been shown in scientific studies
to influence the cellular uptake of the vitamin. So Ester-C is the
smartest choice for a topically applied vitamin C. It won't irritate
the skin; ordinary acidic vitamin C (ascorbic acid) may. It
penetrates through the tough epidermal barrier of the skin; other
forms of vitamin C - including many fat-soluble forms - have not
been shown to do so.
Ordinary vitamin C is
prone to oxidation and decomposition because it's unstable in water.
Since most cosmetics are complex emulsions containing oil and water,
ordinary vitamin C can't possibly remain stable.
Ester
C - vs. - Vitamin C:
Every cell in skin requires Vitamin C for proper functioning.
Ordinary Vitamin C in most skin care products is unstable, acidic
and degrades quickly, losing 90% of its potency within 30 days after
bottling.
Ester C Topical is a patented form of non-oily, neutral pH and
highly stabilized vitamin C which has an astounding 2 year shelf
life, thus delivering high quality vitamin C where it is needed
most, the skin. Ester C. Additionally, skin penetration studies
established that topically applied Ester-C Concentrate can penetrate
the skin to access viable cells and tissues involved in the
maintenance and repair of skin integrity.
To prove that Ester C Topical achieves greater stability than
ordinary vitamin C, scientists at Inter-Cal pioneered laboratory and
analytical methods that gauge the stability of vitamin C liquids,
topicals and cosmetics. Extensive accelerated tests revealed the
remarkably long shelf life of Ester C Topical... and the remarkably
short shelf life of ordinary vitamin C. To understand the stability
concept,But as this chart shows, its vitamin C content deteriorates
very rapidly. By contrast, the vitamin C in Ester C Topical lasts
over two years with a potency of 90%.
The Inter-Cal Corporation developed Ester-C Topical to provide the
personal care industry with a way of fortifying any skin, lip, hair
or sun care product with a stable form of vitamin C that
penetrates.
Infiltrating the largest organ of the human body, the skin, and
reaching its deep dermal layers is key to stimulating the renewal of
cells. Many attempts have been made, but the results have been
disappointing due to poor formulation and poor vitamin stability.
Scientists at Inter-Cal set out to prove that Ester-C Topical could
reach down to deep layers of the skin where collagen and other
important support structures are produced. In an independent test,
Ester-C Topical (14% vitamin C) and a cream containing 1% Ester-C
Topical were applied in a randomized pattern to eight sites on the
skin of the inside forearms of five subjects. The test showed that
vitamin C from both were able to penetrate the skin barrier to
access the cells and tissues involved in the maintenance and repair
of skin.
The true measure of Ester-C Topical's effectiveness came in a
controlled test using 39 volunteers. Participants in the study
discontinued use of other creams and lotions, and applied 2%
Ester-C Topical cream twice a day. The women - predominantly
middle-aged - evaluated the cream for four to five weeks, using it
on the face, hands, legs, heels and elbows. Most were "medium"
complected and had "dry" skin. Rough and/or chapped skin was
reported to be the most common skin problem. Split skin and acne
were also frequently noted at the start of the survey. it protects from future damage by promoting cell renewal, boosting
collagen production and providing antioxidant protection.

A Technological Breakthrough:
14.3% pure & stable Vitamin C. The Big news about Ester C is the
shelf life. While most Vitamin C used in topical products is so
unstable that 90% of its potency is gone after the first month (30
days). C Factor's main ingredient, Ester-C Topical retains 90% of
its Vitamin C activity for 2 years (730 days). This translates to
more potency in the bottle, so when you apply it, it sends
concentrations of stable vitamin C directly into the skin.
Vitamin C Ester Cream Info:
In organic chemistry and biochemistry esters are substances that
have the functional group (R-COO-R') (the carbon is double-bonded to
one oxygen atom and single-bonded to another) and consist of an
alkane united with the residue of any oxygen acid, organic or
inorganic. An ester is a product of the reaction of an acid (usually
organic) and an alcohol (the hydrogen of the acid R-COOH is replaced
by an alkyl group R"). Esters mainly result from the condensation
(this is, a reaction that produces water) of a carboxylic acid and
an alcohol. The process is called esterification. This reaction can
be catalysed by the presence of H+ ions. Sulphuric acid is often
used as a catalyst for this reaction. The name ester is derived from
the German Essig-Aether, an old name for acetic acid ethyl ester
(ethyl acetate). This is the general displayed formula of an ester:
image:GeneralEster.png .
Naming of esters:
Esters can be produced by an equilibrium reaction between an alcohol
and a carboxylic acid. The ester is named according to the alkyl
group (the part from the alcohol) and acetate (the part from the
carboxylic acid) which make it up; for example, the reaction between
methanol and butanoic acid yields the ester methyl butanoate (as
well as water). The simplest ester is H-COO-CH3 (methyl formate,
also called methyl methanoate). The hydrogen atom on the left can be
replaced with a CH3 group or additional CH2 units, producing other
methyl esters, including methyl stearate, a component of biodiesel.
Physicals:
Esters can participate in hydrogen bonds as hydrogen-bond
acceptors, but cannot act as hydrogen-bond donors, unlike their
parent alcohols. This ability to participate in hydrogen bonding
makes them more water soluble than their parent hydrocarbons.
However, the limitations on their hydrogen bonding also make them
more hydrophobic than either their parent alcohols or parent acids.
