Skin Irritation
None of these products contain Sodium Laureth Sulphate or its sister Sodium Lauryl Sulphate
Sodium Lauryl Sulphate is routinely used in clinical studies. This may
suggest a level of comfort and familiarity but the way in which SLS is used is
disturbing. Despite being the number one active ingredient in virtually all
soaps, shampoos and cleansers, the sole purpose of using SLS in clinical studies
is to cause skin irritations. For years, we have been applying known irritants
to our skin on a daily basis. To quote the ACT report "The abbreviated symbol
for Sodium Lauryl Sulfate is used around the world in clinical studies as a skin
irritant. SLS is the universal standard, by which a measured percentage is
evaluated to promote a given level of irritation and reaction. By this SLS
standard level of irritation, it is then possible to evaluate the healing or
modifying characteristics of any ingredient or formula used on the SLS irritated
skin." In other words SLS irritates the skin to a 50% irritation…. What can be
used within the product to reduce that irritation?
Most worryingly, irritation has been shown to occur at concentrations of 0.5%,
which is 1/60th the concentration found in some hand soaps.
In the last 100 years or so, many new health problems have come to light. These
include PMS / PMT, the so-called "menopausal symptoms" which never used to
exist, and more recently a massive drop in male fertility which threatens our
continued existence in many western countries. SLS is most likely a major
contributor to all of these problems due to its oestrogen mimicking activity.
Oestrogen is a hormone found quite normally in both men and women. Like all
other hormones, it’s circulating levels are rigidly controlled by the glands of
the body due to the potent effect of its presence on virtually all cells. Not
only does SLS irritate the skin, it is also absorbed through the skin. Once in
the body, the SLS molecule attaches to oestrogen receptors, mimicking the
effects of the hormone in various body systems.
The result is hormonal chaos. The body can no longer control it's own oestrogen
levels (or at least, what it sees as it's own oestrogen levels - it can't tell
the difference between endogenous oestrogen and SLS) and therefore loses control
of many normal endocrine (hormonal) functions.
In men, whose oestrogen levels are normally extremely low, this massive increase
causes breast enlargement, reduction of male hormone levels and a massive drop
in both sperm count and sperm motility (ability of the sperm to fertilise an
ovum). Gender confusion may also be related to SLS levels, either in the male
himself or in his mother during pregnancy.
In women, the reproductive system, which is totally controlled by oestrogen and
progesterone, goes haywire. Rapidly shifting oestrogen levels and their effect
on progesterone levels mean that the body is totally confused, leading to
menstrual problems, menopausal symptoms and potentially infertility.
Have you ever got shampoo in your eyes? Yes, so have I - not pleasant is it?
However, the potential effects of SLS on the eye are much more worrying. In
animal studies, 10% SLS caused acute corneal damage. However, it is not just
direct eye contact that is the problem. According to the American College of
Toxicology, "tests show permanent eye damage in young animals from skin contact
in non-eye areas".
In other words, because SLS is absorbed through the skin, it can cause PERMANENT
eye damage WITHOUT ever directly coming into contact with your eyes. As a
result, you would expect that children’s products would be SLS-free.
Unfortunately not, most childrens shampoos contain just as much SLS as those for
adults.
Thankfully, alternatives DO exist, though you would be hard-pressed to find them
in your local chemist or supermarket.
Protein Denaturing
Our cells are made from protein. The development of those cells is strictly
regulated by the reproductive processes that are continually at work removing
damaged and old cells and replacing them with healthy new ones. Virtually every
cell in the body is replaced at least every 7 years.
SLS exerts its effects on proteins by forming a chemical bridge between the
fat-soluble and water-soluble parts of the protein molecule. This disrupts the
hydrophobic forces needed to maintain the protein structure and the molecule
collapses, rendering it useless. This effect is usually irreversible.
The result of this is two-fold. Firstly, existing proteins are damaged, leading
to an increase in the amount of healing required by the body. Secondly, new
proteins can be damaged and cells disrupted while they are under construction.
It is exactly this type of activity that can lead to the early stages of skin
cancer.
In the skin, this process can be so severe, that skin layers may separate and
inflame due to its (SLS's) protein denaturing properties.
Carcinogenicity
Quite apart from it's potential to cause pre-cancerous conditions by denaturing
proteins, the oestrogen mimicking effects of SLS also offers massive potential
to cause cancer. It is known that many cancers, not least breast and ovarian
cancer are directly related to oestrogen levels, in fact some cancer cells
actually secrete their own oestrogen, which contributes to the growth of the
tumour.
Clearly, by disrupting normal oestrogen levels AND by causing similar effects at
a cellular level as endogenous oestrogen, SLS exhibits MASSIVE potential to both
cause and worsen cancerous states. The incidence of breast cancer has increased
several-fold in the last 50 years, both in women and in men. Currently, men
account for approximately 1% of all breast cancer cases.
There is also a third way by which SLS can potentially cause cancer.
Carcinogenic nitrates can form in the manufacturing of Sodium Lauryl Sulfate or
by its inter-reaction with other nitrogen bearing ingredients within a
formulation utilizing this ingredient (many shampoos contain nitrate compounds).
A single shampooing can produce more cancer-causing nitrates in the body than
eating a pound of bacon, which is VERY high in nitrates!
Whether it is by these means or not, SLS in a known mutagen - it is capable of
damaging the genetic material found every cell in your body. As mutagenicity has
been strongly linked to cancer, this is a major concern.

-carcinogenic herbs. Su Hagan is available to discuss any of these issues by
email with you should you be interested.
