Health & Safety Issues
For
details of potentially harmful ingredients of cosmetics not required to
be listed on labels, see Ingredient’s We Don’t Use under
Ethoxylates, 1,4-Dioxane and
Nitrosamines.
Disclosure Regulations
Law
requires all ingredients to be identified on cosmetic goods sold in
Australia and most countries around the world. The stated purpose of
these regulations is:
-
to
enable consumers to identify products containing ingredients which may
irritate them, cause an allergic reaction, or be potentially harmful;
-
to enable consumers to make value comparisons between similar products.
We are active in raising the following important product safety issues to public view:
1. Allergens in Cosmetic Raw Materials
Many
cosmetic raw materials are preserved with objectionable preservatives
such as parabens and formaldehyde. Cosmetics that contain these raw
materials are not required to list these preservatives on the label -
only preservatives added by the manufacturer to the finished cosmetic
product are required to be listed on the label. Hence many cosmetics on
the market contain objectionable preservatives that are not listed on
the label, so consumers beware!
The DBF Company do not use any raw materials that are preserved with parabens and formaldehyde (also called formalin).
2. Potentially Harmful Impurities in Cosmetics
For
details of potentially harmful ingredients of cosmetics not required to
be listed on labels, see ethoxylates, 1,4-dioxane, and Nitrosamines.
3. Value comparisons between products
The
regulations currently state that "ingredients must be listed in
descending order by volume or mass, however ingredients present at less
than one-per cent may be listed in any order."
Consumers
should be aware that very dilute herbal extracts such as certified
organic floral waters (a by-product of making essential oils) are
commonly added to cosmetic products. This to us is a deceptive practice
in that consumers believe these products are more “herbal” or “natural”
than is actually the case.
The DBF Company
use only special ingredients that have a proven beneficial effect to
the skin when applied externally. Even more importantly these special
ingredients are used in concentrations at which beneficial effect is
proven.
We don't use the following ingredients:

Ethoxylates
"A lot of chemicals used in cosmetic formulations are synthesised by
ethoxylation: the bulk of anionic and nonionic cleansers and certain
thickeners, for instance. Ethylene Oxide is a hazardous and very toxic
reactant, which is classified by the International Agency for Research
on Cancer (IARC) as category 2A, probably carcinogenic for humans. The
eventual presence of free ethylene oxide in PEG derivatives or
ethoxylates is a concern for food and pharmaceutical authorities
worldwide.The problem of 1,4-dioxane affects the same type of chemical
substances. In fact, dioxane is a derivative of ethylene oxide and is
often present in ethoxylates. Dioxane is considered to give possible
risks of irreversible toxicological damage. "
- Extracted from academic cosmetic chemist, Denis
Rebut, and is taken from Cosmetics and Toiletries Journal, Vol 104,
April 1994.
The following is a list of some of the most commonly used ethoxylated ingredients:
-
Sodium laureth sulfate (SLES)
-
Ammonium laureth sulfate
-
Triethanolamine laureth sulfate
-
All ingredients with "eth" in the name eg Ceteth 20
-
All ingredients with "PEG" in the name
-
All the Polysorbates
It should also be noted that ethoxylated ingredients are inherently
unstable (due to the presence of an ether linkage). They have been
shown in a Sicilian study to break down when applied to the skin in a
cosmetic cream to form skin-damaging free radicals.
For purity and safety reasons, The DBF Company do not use of any ethoxylated ingredients.
Sulfates and Petrochemical Cleansers
-
Sulfates
is the colloquial name for a group of cleansing ingredients called
alkyl sulfates, which are amongst the most irritating ingredients in
personal care products, yet used by almost every manufacturer
worldwide. Ammonium lauryl sulfate is the most strongly irritant,
followed by sodium lauryl sulfate.
-
Petrochemical
cleansers tend to be harsh and irritating. Examples include sodium
dodecyl benzene sulfonate and sodium C12-16 olefin sulfonate.
-
Ammonium lauryl sulfate is commonly used to replace sodium lauryl sulfate, which is the subject of negative publicity.
The following table shows this replacement is significantly more irritating than SLS. See
FAQ for further details.

Preservatives
Preservatives
are the most common cause of allergic reaction to cosmetics. Toxic
preservatives such as methylchloroisothiazolinone (KATHON CG) and
formaldehyde (formalin), should be avoided. The more irritating and
allergeric preservatives, such as the formaldehyde donors
imidazolidinyl urea, diazolidinyl urea, 2-bromo-2-nitropropane-1,3
diol, iodopropynyl butylcarbamate and DMDM hydantoin and quaternium 15,
should also be avoided.
Take care when
looking at products which make a feature of using "natural"
preservatives. Such ingredients generally have a narrow spectrum of
activity and other preservatives must supplement their action. A
well-known example is grapefruit seed extract which itself has minimal
or even zero antibacterial properties. Most grades on the market have
been tested and shown to contain the synthetic preservatives, parabens
and benzethonium chloride. Visit this link for further information
http://www.ars.usda.gov/research
Parabens
are the most commonly used preservative in a wide range of cosmetic and
toiletry products. They are also the most common ingredient (apart from
water) in personal care products and can be present in high
concentrations. The DBF Company do not use ingredients which have been preserved with parabens.
Formaldehyde
Formaldehyde
is an effective and cheap preservative which is used in some major
brand hair care products. It is toxic, carcinogenic, and probably the
most irritating ingredient used in personal care products. It is listed
as "formalin" on product labels instead of its common name,
formaldehyde, to veil its presence. This is currently legally
acceptable practice. Consumers beware!
Formaldehyde
also finds its way into a wide range of cosmetics and toiletries as a
preservative of raw materials. Formaldehyde is termed an "incidental
ingredient" by the current Cosmetic Ingredient Disclosure Regulations
when used in this way, and is exempted from having to be listed on the
label! People with sensitivities should check with their cosmetics
supplier for an assurance that formaldehyde is not used to preserve any
raw ingredients used in their products.
"Formaldehyde is intensely irritating to mucous membranes, is toxic and a known skin sensitiser."

Propylene Glycol & Organochlorines
Propylene
glycol is an ingredient in most cosmetics and toiletry formulations. It
is a humectant, which attracts water to itself and prevents creams from
drying out. It is also a solvent. In fact, most herbs are extracted
into propylene glycol. Propylene glycol is a petrochemical derivative -
it is a primary irritant and can cause delayed contact
hypersensitivity. It is commonly used instead of glycerin or sorbitol,
both particularly safe and highly effective plant-derived humectants,
because it is cheap. Consumers who are concerned about allergies and
sensitivities to cosmetics would be well advised to avoid products
containing propylene glycol, choosing instead those which use glycerin
or sorbitol.
Avoid chlorinated organic
compounds, as chlorine in its organic form (ie combined with carbon) is
a chemical recipe for toxicity. In the personal care arena, for
example, the quaternaries (or quats) containing chlorine eg
stearalkonium chloride are amongst the most irritating ingredients used
in personal care products. It is therefore wise to choose quats which
do not contain chlorine - if, for example, the methosulphate grouping
replaces chlorine, extremely mild detanglers such as behentrimonium
methosulfate can be formed.
Solubilisers, Colours & Foam Boosters (DEAs)
Solubilisers
are used to dissolve small amounts of oil (usually fragrances) in
water-based products, such as skin toners and floral waters.
Solubilisers are not used in our products for two reasons. Firstly,
they are powerful solvents, and can have a detrimental effect on the
skin. And secondly, they are all ethoxylated ingredients, and are
therefore always contaminated with toxic impurities.
The solubilisers most commonly used include:
Colours
do not have any function in cosmetics and toiletries (except for colour
cosmetics) other than to make the product look more appealing to
consumers. A common industry practice is to add a colouring material to
make the product appear to contain a higher level of a featured
ingredient eg adding green chlorophyl to a Rosemary Shampoo. Added
colours are also a leading cause of allergies and it is best avoided. The
DBF Company
do not use any colour additives; hence most of the shampoos are clear
(exception is the Lemongrass Shampoo which has a rosy or orangey colour
depending on the season) and other products are cream.
Foam
boosters are used in virtually all shampoo and body wash formulations.
These ingredients, being derivatives of monoethanolamine (MEA), or
diethanolamine (DEA), are known to be always contaminated with varying
levels of toxic Nitrosamines. The most commonly used foam boosters are
Cocamide MEA or DEA and Lauramide MEA or DEA. The DBF Company do not use these foam boosters.
1,4-dioxane
"A
lot of chemicals used in cosmetic formulations are synthesised by
ethoxylation: the bulk of anionic and nonionic cleansers and certain
thickeners, for instance. Ethylene Oxide is a hazardous and very toxic
reactant, which is classified by the International Agency for Research
on Cancer (IARC) as category 2A, probably carcinogenic for humans. The
eventual presence of free ethylene oxide in PEG derivatives or
ethoxylates is a concern for food and pharmaceutical authorities
worldwide.
The problem of 1,4-dioxane affects
the same type of chemical substances. In fact, dioxane is a derivative
of ethylene oxide and is often present in ethoxylates. Dioxane is
considered to give possible risks of irreversible toxicological damage."

"Cosmetics
containing ethoxylated surfactants may be contaminated by 1,4 dioxane,
which has been shown to be carcinogenic in rats and mice and to be
absorbed through the intact skin of animals. Furthermore, this compound
has been classified as a possible carcinogen to humans. According to
the European Economic Community directive on cosmetics, 1-4-dioxane
must not be present in commercial products. Consequently, the assay of
this substance in marketed cosmetics is of direct concern to
consumers.”

Santo Scalia, Fabio Testoni, Giuseppe Frisina and Mario Guarneri
"Within
the shampoo manufacturing sector of the cosmetics industry there is
concern about the level of residual 1,4-dioxane present in final
shampoo products. The 1,4-dioxane is introduced into the product via
the use of ethoxylated fatty alcohol sulfates as cleansing agents.
During the process of alcohol ethoxylation, ethylene oxide can dimerize
to form 1,4-dioxane, which is subsequently carried through the shampoo
manufacturing process. This compound has been shown to be carcinogenic
in animals and is listed as a carcinogen with NIOSH.
Concern
over the health risks, along with the probability that the ethoxylated
surfactants in use contain a fair amount of residual 1,4-dioxane, has
lead many cosmetic and toiletry companies to examine the levels of
dioxane in both their raw materials and their finished products.
Although many producers have begun vacuum stripping procedures in their
manufacture of the fatty alcohol sulfates, there can still be high
levels of 1,4-dioxane remaining in the materials that will be
inadvertently added into finished product."
"A
variety of commercially available cosmetics were analyzed for
1,4-dioxane. The products included shampoos, liquid soaps, sun creams,
bath foams, moisturizing lotions, cleansing milks, after-shave balms,
baby lotions, day creams, and hair lotions. Of the total products
investigated, 56% contained 1,4-dioxane with levels ranging from 3.4 to
108.4mg/kg."
"It should be stressed that even
when the 1,4-dioxane content is low, under appropriate conditions of
cosmetic use, long-term application to skin is common."

Nitrosamines
The
presence of nitrosamines in personal care products is a major concern
within the cosmetics industry. Nitrosamines are formed as pollutant
by-products in a number of cosmetic raw materials. They may also be
formed within the cosmetic itself after it is made. As a group,
nitrosamines are toxic and carcinogenic. They are commonly found in
association with ingredients such as the foam boosters lauramide DEA,
cocamide DEA and the amine oxides, and the hair detangler stearalkonium
chloride.
The DBF Company do not use ingredients known to be contaminated with Nitrosamine impurities.
"N-nitrosamines
are a group of chemical compounds which have been found in a variety of
consumer products, including cosmetics and toiletries."
"N-nitrosamines
found in a variety of personal care products are either introduced by
contaminated raw materials, or formed within the product itself by the
reaction of precursors. Limited surveys of cosmetic raw materials have
shown that N-nitrosamines are present in approximately 30% of the raw
materials analyzed, occasionally at levels up to 1 ppm. However, a
comparison of the N-nitrosamine levels found in cosmetic raw materials
with those reported in the finished products shows that although some
degree of N-nitrosamine contamination of personal care products may be
due to the raw materials, formation in the product from precursors is
the principal source of N-nitrosamines in these products."

"The
contamination of cosmetics by N-nitrosamines is a problem of
international concern. Most of the ca. 130 - N-nitrosamines (NNA)
tested to date have proven to be potent carcinogens in a number of
animal species, including primates, and they have been ranked as second
in carcinogenic potential only to the aflatoxins. The N-nitrosamine of
chief concern to the cosmetic and toiletries industry and regulatory
agencies is NDELA, whose carcinogenicity was first reported by Druckrey
et al in 1976 and later identified as a potent animal carcinogen."
"Reports
of widespread NDELA occurrence in a variety of cosmetics and toiletries
by Fan et al., the FDA and Spiegelhalder and Preussman have taken on
added significance with the demonstration that NDELA is absorbed
percutaneously and has been found to be excreted in the urine of a
human subject, following topical application of an NDELA-contaminated
cosmetic. Qualitatively, topical administration of NDELA has been shown
to induce the same types of tumors in hamsters as either oral swabbing
or subcutaneous injection." -The Andrew Jergens Company, Steven W

"The
next troublesome impurities are N-nitrosamines. Here, I believe all
will accept that there is a genuine cause for concern, with a general
recognition within the industry that N-nitrosamines are potential
carcinogens in man." - 'How Green is My Shampoo' by J E Hodgson, et
al, Albright & Wilson Ltd, UK. Presented at the Joint ASCC/NZSCC
Conference, Tororua, New Zealand, March 1991.
