FDA has been vigilant about
potentially hazardous chemical ingredients in cosmetic products, and warning
consumers about the health risks of such products. Many ingredients in
cosmetics have been the subject of news reports or have been topics of
discussion on the internet.
Since there is laxity in enforcing
many quality and safety standards, especially when the suppliers are online marketing
companies, making unverifiable claims, it is useful to learn about some harmful
chemicals that are found even in branded beauty or skin care products.
1.Coal
Tar Dyes : Coal tar dyes are colour ingredients
that were originally made from chemicals extracted from coal tar, and the
distillation process was not 100% effective so harmful impurities were often
left in the product.
2.Diethanolamine (DEA) and other ethanolamines : Diethanolamine (DEA) is unacceptable for use in cosmetics in
Canada and many countries. This is because DEA and similar compounds like
diisopropanolamine (DIPA) can form harmful nitrosamines that may be linked to
cancer.
3.Formaldehyde
(and Formaldehyde-releasing preservatives) : Formaldehyde
is used in small amounts in hair and skin cosmetics as a preservative, to
maintain the integrity of the product and prevent growth of microorganisms. It
is formed endogenously in humans as a normal result of metabolism. When inhaled
at high levels, however, formaldehyde is anticipated to be a human carcinogen.
4.Lead and other heavy metals :Due to health concerns, heavy metals such as lead, arsenic,
cadmium, mercury and antimony are considered unsafe and should not be used as
cosmetic ingredients. Yet impurities exist due to the persistent nature of
these substances. Many countries have specified impurity limits in the hope
that cosmetic industry will follow them.
5.Parabens :Parabens
are used as preservatives in many cosmetic and personal care products,
moisturizers, hair care and shaving products. These have been found to weakly
mimic estrogens in animal studies, raising concern because of their link with
breast cancer.
6. PEG compounds :PEG, or poly(ethylene glycol) compounds are used to make
non-ionic surfactants (surfactants allow for easier spreading of cosmetics).
There are hundreds of different types of PEG compounds in cosmetics. The U.S.
Cosmetic Ingredient Review Expert Panel found that cosmetics containing PEGs
should not be used on compromised skin (such as skin that is broken or has a
rash).
7. Petrolatum
: Petrolatum (mineral oil jelly) is
used widely in cosmetics as a moisturizer as well as in over-the-counter drugs
as a skin protectant. Cosmetic petrolatum products are made from highly refined
petrolatum at pharmaceutical or cosmetic grade. Manufacturers are expected to
ensure that this ingredient is not susceptible to impurities.
8. Phthalates : Phthalates are used in cosmetics as plasticizers (to keep
nail polish supple), perfume solvents, fixatives and antifoam ingredients. These
are considered safe only if used att the levels at which they are currently
used in cosmetics.
9. Para-Phenylenediamine (PPD) : It is a coal tar dye commonly used in permanent and
semi-permanent hair dyes, colours and tints. Used with oxidizing agents like
hydrogen peroxide to create colourant molecules,PPD is known to be a sensitizer
when used on the skin (causes allergic reactions upon repeat exposure in some
people.
10. Siloxanes : Cyclomethicone and siloxanes are used in cosmetics to
soften, smooth and moisten. Siloxanes are found in the vast majority of hair
care and skin conditioning products. Disclosure of ingredients on product
labels of cosmetics is mandatory in many
countries.
11. Sodium Lauryl Sulfate (SLS) : SLS is most often used as a cleansing and foaming agent in
rinse-off products like shampoos, bath products, shaving creams and skin
cleansers; also sometimes found in other cosmetics like creams and lotions. At
high levels, SLS can cause skin or eye irritation, which is why it is important
to follow label instructions on cosmetic product.
12. Triclosan : Triclosan is used in cosmetics as a preservative to prevent
or slow down microbial growth and protect products from spoilage; also used in
over-the-counter drugs and other consumer products, and is safe when used in
cosmetics at a concentration of up to 0.03%.
