A person easily uses a dozen or more fragranced products in a day. Many of these products
are applied directly to the skin. [1] The users of these products assume the safety of the
materials used in them, and the final product has been established. It never occurs to
most people that this is not the case. [2]
Fragranced products such perfumes, colognes, and personal care items come under the
jurisdiction of the FDA. However, due to "trade secret" status of fragrance
formulas the fragrance industry is basically self regulated. The ingredients used in
fragrance formulas do not have to be disclosed to anyone, even the FDA.
Increasingly fragranced products are cited as triggering or causing health problems.
Though the industry has in place procedures for establishing the safety of fragrance
materials, these measures are not adequate. The industry has been slow to address the
issues involved. The answers provided by the industry need closer examination.
1. Fragrance materials have a long history of relatively safe use.
It is true that fragrances have been used for centuries. However, until the late 1860s
virtually all fragrance materials were obtained from plant and animal sources. Though
often concentrated through distillation, the materials contained, were close to that
found in nature. No one chemical was found in isolation. Companion chemicals found
together often had synergistic and modifying effects.
The majority of modern fragrance materials are synthesized from petroleum products. Many
are not found in nature. There is no long history of use. The materials that are obtained
from plant material are often extracted as isolates. This means individual chemicals
rather than the complex mixtures found in nature are used. History of use no longer
applies, as the action of individual chemicals may be far different than in mixtures. [2]
2. Compounds are used at such low levels that they are not a health risk.
The current trend in fragrance formulation is toward using powerful long lasting
synthetics at higher levels. One material may make up as much as 25% of the formula. It is
not unusual for four or five materials to make up 80% of the formula. [3]
3. Fragrance materials are safety tested.
The Research Institute for Fragrance Materials (RIFM) safety tests fragrance materials.
Only about 1300 of the more than 5000 materials used in fragrances have been tested for
safety. The testing that is done is generally limited to acute oral and dermal toxicity,
irritation and dermal sensitization, and phototoxicity. Testing is limited to individual
materials, there is little effort to address synergistic and modifying effects of
materials in combination though the RIFM is aware that they occur. Early on in testing it
was found that when similar materials were tested together more positive sensitization
reactions occurred than when the materials were tested individually. Testing procedures
were changed so only unrelated materials were used in a testing sequence. [4]
Most chemical data sheets and MSDS information on fragrance materials plainly state:
"The chemical, physical, and toxicological properties have not been thoroughly
investigated."[5]
4. Present testing is adequate.
Musk ambrette was found to have neurotoxic properties. This was first discovered in 1967
when mice were feed varying levels of musk ambrette. Since dietary consumption of musk
ambrette is generally very low, the impact was discounted and no assessment was made of
exposures from fragranced products. In 1985 after studies were published on the neurotoxic
effects and it was determined musk ambrette was readily absorbed through the skin, the
IFRA recommended that Musk ambrette not be used in direct skin contact products. Musk
ambrette had been used in fragranced products since before the 1920s. [6]
Versalide (AETT) had been used in the fragrance industry since the 1950s. In the mid-70s
it was discovered by accident that this material was severely neurotoxic and caused the
internal organs of mice to turn blue. [7]
Perfumes and fragrances are recognized as triggers for asthma by the American Lung
Association and other organizations concerned about respiratory health. [8], [9]
In spite of legitimate concerns, the industry does not include testing for the
neurological and respiratory effects of fragrance materials.
5. The industry can adequately regulate itself to ensure the safety of fragranced
products.
The International Fragrance Association (IFRA) takes the information obtained from the
RIFM materials and establishes guidelines for safe use of fragrance materials. These
guidelines are not binding and there is no enforcement by the industry.
In 1985 the IFRA recommended that Musk ambrette not be used in direct skin contact
products. In 1991, the FDA still found Musk ambrette in skin contact products.
Musk xylol is found in water ways and aquatic wildlife. It is being found in human adipose
tissue and breast milk. In spite of this the IFRA has made no restrictions or
recommendations concerning its use.
6. Only a small segment of the population has adverse effects from fragrances.
1-2% of the population has skin allergies to fragrances. Fragrance is one of the most
common causes of adverse reactions to cosmetics. [10], [11]
Asthma rates have doubled in the past twenty years. In 1994 there were over 14 million
asthmatics. [12] Perfumes and colognes trigger 72% of asthmatics. [13] Each year over 35
million people suffer from sinusitis. [14] Fragrances are general irritants that
contribute to the incidence of sinus problems. For some they are the primary triggers for
upper and lower respiratory illnesses.
Migraines effect as many as 25 million people. Fragrances are known triggers for migraine
headaches. [15]
Many other health conditions are adversely affected by fragrances. Those with chronic lung
disease find exposure to fragrances exacerbate their condition. Those receiving
chemotherapy for treatment of cancer often find exposures nauseating.
In Canada, fragrance manufactures have developed an organization called ScentedProducts
Education and Information Association of Canada This organization has a web site that
addresses Multiple Chemical Sensitivity (MCS) and the issues raised by those with MCS that
are adversely affected by others fragrance use. The controversial aspects of MCS are used
to downplay the significance of fragrances as a health issue. There is no mention of
impact on health of those with asthma, allergies, upper respiratory problems, chronic lung
disease, or migraine headaches; conditions that are well documented in medical literature
as adversely affected by fragranced products.
In the US, Glenn Roberts, spokesperson for the Research Institute for Fragrance Materials
says the industry is not aware of any increased complaints. [17] However, the issue of
fragrance sensitivity was discussed at the 1996 CTFA Scientific Conference and Annual
Trade Show. The industry was aware of the Berkeley, California proposal to ban fragrances
at public meetings and other efforts to curtail exposure to fragranced products.
" This attempt to regulate fragrances was not one isolated incident. In
Massachusetts, there is an effort to regulate fragrance inserts in magazines. One possible
solution may be to require odorless sealed packets for all fragrance samples; resolving
this issue may very well involve the U.S. Postal Service because it regulates the use of
such inserts." [18]
Though the issue of Multiple Chemical Sensitivity has brought attention this issue, the
adverse effects of fragrances is a general health issue that affects millions of Americans
on a daily basis and should be of concern for everyone. It is unfortunate the industry has
chosen not to address this issue in a responsible manner. This short sightedness only
serves to increase doubts over the industry's ability to regulate itself.
In light of the Fragrance Industry's unwillingness to adequately address the issue of
fragrance safety, it is time for the FDA to intervene. Though FDA resources are limited
there are cost effective means of acting and ensuring the safety of the public's health.
Programs and resources already in place can be utilized to more effectively monitor the
safety of fragranced products.
Make available "fact sheets" that acknowledges exposure to fragrances can
exacerbate or trigger asthma, sinus and upper respiratory problems, migraines and other
disorders. It is important that consumers are aware that the FDA does not require
pre-market testing of products. Many parents with asthmatic children are not aware that
the products they use may be contributing to their child's illness. Such education would
also increase the awareness that "second hand" fragrance can cause problems for
others. Many parents are also unaware of the general consensus among pediatricians that
fragranced products should not be used on infants.
Expand the Cosmetic Adverse Reaction Monitoring so that complaints can be registered via
the FDA web site. This would make it easier to file complaints. Data could be used to
pinpoint specific products that are problematic.
The National Center for Toxicological Research can be utilized to analyze fragrances that
are problematic. The results can be examined to determine if there are substances or
formulations that common in the products that complaints have been filed. Further the
results of analysis can be examined to be sure materials banned (voluntarily or by law)
are not present. Also any lack of compliance with IFRA recommendations for restricted
materials should be noted. The product should also be examined for proper labeling, etc.
The vast numbers of materials used in fragrances makes the task of ensuring safety of each
and every substance beyond the scope of the FDA's resources. However, by closer
examination, several reasonable points to start can be determined. The "Fragrance
Mix" patch testing is diagnostics for the majority of skin allergies to fragrances.
These materials would be a good place to start in determining if fragrance materials can
also act as respiratory sensitizers.
More complaints are registered concerning fragrances formulated since the mid-eighties.
Examination of these products may provide clues as to why these formulations are
frequently cited as causing problems. Materials were brought into common use should be
closely examined. Some materials may have been used on a limited basis previously, but
newer information increased their use. For example in the late seventies it was found that
amylcinnamaldehyde and hexylcinnamaldehdye had the ability to hold the scent even after
washing and rinsing. Though both of the materials had been in use for some time, usage in
products with a "wet" application increased.
Materials introduced in the past several decades needs to be closely monitored, as they
have no history of use. This is especially true of the newer materials that are used at
relatively high levels in modern fragrance formulas. Fragrance materials are not the only
things that need examining. Newer technologies such as the use of cyclodextrins also need
to be examined to determine if the use of such materials add to the health risks.
Though health risks from an individual fragrance may seem insignificant, the sheer numbers
of fragranced products used make them a concern. Further bioaccumulation of fragrance
materials increases the concern. Presence of fragrance chemicals in fat tissue and breast
milk raises the issues of effects on the fetus and nursing infants. These are health
concerns that should not be ignored. Increases in asthma and other respiratory problems
triggered by fragrance exposure raises concerns over effects on the airways and the lungs.
These and other concerns need to be addressed by the FDA and the fragrance industry.
