I happened upon Paco Rabanne Metal about 7-8 years ago in a discount bin at either Marshalls or TJ Maxx for img Max Factor Colour Perfection eye Shadow gif around $25 bucks. I was clueless to what it smelled like. I think, at the time, I was confusing it with its far more well-known friend, Paco Rabanne Calandre. In my mind Calandre was something to have, and finding it for cheap was a completely sane, justified, unsniffed purchase. 
Due to an ongoing family crisis, I have been unable to blog for some months now, since I have to focus my energies on the healing process for my mother. On July 27, 2010, I posted a link, via the private forum for the members of the Natural Perfumers Guild, to the petition against the Safe Cosmetics Act of 2010. Shortly after that, I started a blog on the subject, wanting to state the Guild's position and to link with others opposed to this egregious Act that will put us out of business, but I was pulled off the post by my family obligations - I just didn't have the time, nor could I focus to write a good, informative blog.
Guild Associate Robert Tisserand has graciously allowed me to post his recent blog on the matter here, and on the Guild blog, and use it as the Guild's position on this matter. Thank you, Robert, for coming to my aid in this time of stress. Robert helped me co-author a position paper against the proposed 40th Amendment of IFRA in 2007, and I always appreciate his logical and precise way of getting to the heart of the matter and writing in a lucid manner about a subject.

Here is the text of his blog:
The Safe Cosmetics Act 2010
The Safe Cosmetics Act of 2010 (SCA 2010), now before the House of Representatives, is an inappropriate and seriously flawed attempt to make cosmetics safer. You can read the full text here. The thinking behind it is identical to a bill that was proposed (and defeated on March 1st this year) in Colorado (see Tunnel vision). Both are the brainchild of a group including the Campaign for Safe Cosmetics (SFSC) and the Environmental Working Group (EWG) which are in turn linked to the Skin Deep database. SCA 2010 is being opposed by groups representing small businesses such as Opposesca.com, the Indie Beauty Network and Personal Care Truth which also reflects the views of many cosmetic chemists. A petition opposing SCA 2010 can be found here.
SCA 2010 is unscientific, unworkable, and if passed as is, would likely cause widespread job loss in the cosmetics industry. Far from being a step in the right direction, it would be a leap into regulatory chaos, as well as targeting small businesses and natural products.
Yes, cosmetics could and should be safer, and cosmetics labeling in the USA does need more transparency. Safety can always be improved in any field, especially in the light of new scientific data, but SCA 2010 over-reaches what is needed to such an extent that, with the possible exception of distilled water, I cannot think of any cosmetic ingredient that would be acceptable under its terms.
These require that there is “data demonstrating that exposure to all sources of the ingredient or cosmetic present not more than 1 in a million risk for any adverse effect in the population of concern”. Unfortunately, “population of concern” is not defined, but SCA 2010 further states that, in establishing a safety standard, “no harm will be caused by aggregate exposure for a member of a vulnerable population to that ingredient or cosmetic.” “Vulnerable populations” are defined, and include “pregnant women, infants, children, the elderly, and people with compromised immune systems.” Would “infants” include pre-term babies? Would “people with compromised immune systems” include those who do not get sufficient sleep, or who suffer from frequent colds? Much of the wording of the bill is vague and open to many possible interpretations.
“Ingredient” includes every substance present in an ingredient “at levels above technically feasible detection limits.” This last phrase is not defined, but it could be as low as one part per billion (ppb, 0.0000001%) or one part per trillion (ppt, 0.0000000001%). SCA 2010 specifically mentions contaminants, and in foods and beverages they are commonly measured at these levels.
Most essential oils contain about 100 constituents. The above data – for example no more than 1 in a million risk – must be demonstrable for each one of these constituents. Otherwise, the essential oil may not be acceptable in cosmetics, according to the terms of the bill. I can think of of no substance, natural or synthetic, that is known to cause no adverse reaction of any kind in less than 1 in a million people. In human tests for skin reactions, there are sometimes data covering tens of thousands of patch tests. But, that’s still a long way from a million, and there is no cosmetic ingredient that, if patch tested on one million people, would cause no more than one reaction. Except for distilled water perhaps.
“Any adverse effect” is not defined, but is not as simple as it might seem. Linalool, for example, has caused CNS depression when inhaled by animals. (Alcohol is the classic CNS depressant – in large enough amounts, it causes loss of muscular control, slurred speech, stupor and other effects.) Linalool is one of the most common constituents of fragrant herbs and flowers, inhalation of which could therefore be regarded as hazardous under the vague terms of SCA 2010. In reality, linalool has no more than a mild calming, anti-anxiety effect when inhaled by humans. It’s one of the main constituents of lavender oil.
The issue of dose and concentration is not given much consideration. “The Secretary shall presume that any ingredient or cosmetic that induces cancer or birth defects or has reproductive or developmental toxicity when ingested by, inhaled by, or dermally applied to a human or an animal has failed to meet the safety standard.” This is a complete reinvention of the science of toxicology, which up until now has been based on the principle of dose and of threshold levels. Above certain amounts toxicity may occur, below them it will not. This is why there are permissible levels for substances such as hydrocyanic acid (”cyanide”, restricted to 1 ppm) which naturally occurs in some foods.
There’s also the question of the interaction between the constituents of a natural substance. Basil herb, for example, contains two known carcinogens – estragole and methyleugenol. Pesto is a particularly concentrated form of basil, yet the WHO has determined that the amounts in basil/pesto are so small that they present no risk to humans. Since that ruling, research has been published demonstrating that basil herb contains anticarcinogenic substances that counter any potential toxicity of the two carcinogens, and is itself anticarcinogenic (Alhusainy et al 2010, Dasgupta et al 2004, Jeurissen et al 200
. Some basil essential oils have been shown to have anticarcinogenic effects (Aruna & Sivaramakrishnan 1996, Manosroi et al 2005).
Probable or known human carcinogens, such as acetaldehyde and benzo[a]pyrene (BaP) are ubiquitous in fruits, vegetables, dairy products, meat and fish at low ppb. I’m not saying this is a good thing, I’m just saying it’s a fact, and these foods are not regarded as dangerous, because the toxins are present in such minuscule amounts. BaP is one of the many carcinogens found in cigarette smoke, but it is also found in American drinking water at 0.2-2.0 ppb, and in olive oil at about 3 ppb. Olive oil is actually anticarcinogenic, because of its content of antioxidant polyphenols, squalene, β-sitosterol and linoleic acid (Sotiroudis & Kyrtopoulos 200
. It’s the same story with fruits and vegetables – they are generally anticarcinogenic due to a very much higher content of antitoxic substances.
Many essential oils, herb extracts and foods contain tiny amounts of single constituents that alone, and in substantial amounts, are known to be toxic, but the parent natural substance is not toxic. However, this scenario is not taken into consideration by the CFSC or EWG. These organizations are, wittingly or unwittingly, campaigning to have natural substances banned from use in cosmetics because of their “tunnel vision” and “parts per billion” approach to safety.
The thinking behind the wording of SCA 2010 is naive because there is an assumption that substances are either “safe” or “toxic”, and that if we simply eliminate the toxic ones from personal care products, the world will be a better place. It may seem like an excellent idea, but once you start talking about parts per million or lower, it is unnecessary and unrealistic. Not even foods are regulated to that degree, and our exposure to foods is far greater than our exposure to cosmetics.
SCA 2010 requires that every constituent or trace contaminant of every ingredient be listed onthe product label. This arguably discriminates against natural products, since their ingredient lists would have to include hundreds of substances, if they could be proved to be safe under the terms of the bill, and if there was some way of actually listing that many ingredients on a label. A product containing what would normally would be regarded as five ingredients – olive oil, blue chamomile extract, and essential oils of orange, rose and vetiver – would require an ingredient list looking something like this:
This is one of the reasons that a naturally-occurring chemical is not the same as a synthetic one – the impurities present in the synthetic version. Synthetic coumarin, for example, causes skin allergies because of the impurities it contains (Vocanson 2006, 2007). But, SCA 2010 treats all chemicals of the same name as equal, which may be expedient if you are trying to pass legislation, but it’s not really scientific.
SCA 2010 proposes that hundreds of ingredients should be assessed for safety in unrealistically short amounts of time, with no proposal as to what form this assessment process will take, who will undertake the work, and exactly what criteria will be used. The wording of the bill shows very little understanding of either toxicology or cosmetics science. It also assumes that any existing legislation in other countries must be good legislation, when in fact nothing could be further from the truth.
I happen to believe that incremental legislation is generally a good thing. It at least allows for the possibility of public debate, and for finer points to be properly considered. Legislation as sweeping as SCA 2010 will cause chaos in the cosmetics industry, especially since States will be given the option to add further safety standards as they see fit. So, each State could have different standards – a manufacturer’s nightmare, and a pointless provision. Even without it, how any agency could enforce legislation involving hundreds of thousands of existing products, with hundreds of ingredients to consider for each one is mind-boggling.
SCA 2010 will cost unknown millions or billions of dollars which the consumer will ultimately pay for. It will probably have no more than a negligible effect on cosmetics safety, but it poses a serious threat to many businesses especially those making natural products, those supplying natural ingredients, and the farmers that grow the plants they come from.
SCA 2010 is especially onerous to small businesses (any corporation with a turnover of $7 million or less.) It requires each manufacturer to not only declare every constituent chemical of every ingredient on the label, but to also test each finished cosmetic to ensure that there is not even a trace amount of some toxic chemical that might have been formed during the making of the product. Most small personal care product businesses will not survive if SCA 2010 passes, a fact that may possibly be attractive to larger corporations.
However, the bill has been criticised by Lezlee Westine, President and CEO of the Personal Care Products Council, which represents the larger cosmetics companies. Her statement includes the following: “We are concerned that the Safe Cosmetics Act of 2010 as written is not based on credible and established scientific principles, would put an enormous if not impossible burden on FDA, and would create a mammoth new regulatory structure for cosmetics, parts of which would far exceed that of any other FDA-regulated product category including food or drugs. The measures the bill would mandate are likely unachievable even with the addition of hundreds of additional FDA scientists and millions more in funding and would not make a meaningful contribution to product safety.”
The Skin Deep database, mentioned in the first paragraph, gives an insight into the thinking of the CFSC and EWG. Skin Deep exaggerates toxicity by being selective in its reporting. For example, limonene, the major constituent of citrus essential oils, is flagged as being developmentally toxic in large doses. This is true, since when pregnant mice were fed 2,363 mg/kg limonene by stomach tube on days 7-12 of gestation, there was an increase in the number of fetuses with skeletal anomalies and delayed ossification (Kodama et al 1977).
However, what is not stated by Skin Deep is that in the same report, when pregnant mice were given a lower dose, 591 mg/kg/day, there was no developmental toxicity. The higher dose is equivalent to daily human ingestion of 5.7 oz of limonene, and the lower dose is equivalent to 1.4 oz. If ingestion of 1.4 oz per day for 6 days is known to be non-fetotoxic, then there is no reason to believe that the use of limonene in cosmetics is likely to be in any way hazardous during pregnancy; in fact, quite the opposite (especially since stomach tube feeding generally increases toxicity).
The Skin Deep page on limonene also mentions, under “cancer” that“one or more tests on mammalian cells show positive mutation results.” One reference is given. However, this ignores the fact that eleven other studies found no evidence of mutagenicity or genotoxicity for limonene (Anderson et al 1990, Connor et al 1985, Florin et al 1980, Haworth et al 1983, Myhr et al 1990, Pienta 1980, Sasaki et al 1989, Sekihashi et al 2002, Turner et al 2001, Watabe et al 1980, 1981), and two further studies reported antimutagenic effects (De Oliveira et al 1997, Kim et al 2001). This 13:1 “score” is part of the weight of evidence used to assess risk in toxicology.
Mutagenicity testing is used to identify substances that may be carcinogenic. However, 85% of substances that are not in fact carcinogenic test positive in a least one mutagenicity test (Kirkland et al 2005). These are “false positives”, and present no risk. The one study cited by Skin Deep for limonene is a false positive.
If you want to imply risk, it’s possible to do so simply by being selective about which facts you choose to report. Many small cosmetics manufacturers have become disenchanted with the manipulative ways of the CFSC and EWG. If they were sincere in caring about cosmetics safety they would welcome any pertinent opinions and facts, but they don’t. They either ignore or stridently oppose anything that does not accord with their fear-driven political agenda. It’s a shame, because a few of their concerns are genuine and well-founded, but their focus has become highly distorted.
I urge you to oppose the Safe Cosmetics Act 2010. Here are some steps you can take.

Whether this list of 200 chemicals would be useful for consumers is debatable, and it would be one of the shorter lists, since most natural products contain much more than five ingredients. Even single synthetic chemicals are not really single chemicals at all – they also contain some minor and trace constituents. Most fragrance chemicals for example are about 95% pure, the other 5% consisting of “impurities” which of course would have to be listed. So synthetic chemicals are not exempt from this challenge.
This is one of the reasons that a naturally-occurring chemical is not the same as a synthetic one – the impurities present in the synthetic version. Synthetic coumarin, for example, causes skin allergies because of the impurities it contains (Vocanson 2006, 2007). But, SCA 2010 treats all chemicals of the same name as equal, which may be expedient if you are trying to pass legislation, but it’s not really scientific.

It also assumes that any existing legislation in other countries must be good legislation, when in fact nothing could be further from the truth.
I happen to believe that incremental legislation is generally a good thing. It at least allows for the possibility of public debate, and for finer points to be properly considered. Legislation as sweeping as SCA 2010 will cause chaos in the cosmetics industry, especially since States will be given the option to add further safety standards as they see fit. So, each State could have different standards – a manufacturer’s nightmare, and a pointless provision. Even without it, how any agency could enforce legislation involving hundreds of thousands of existing products, with hundreds of ingredients to consider for each one is mind-boggling.
SCA 2010 will cost unknown millions or billions of dollars which the consumer will ultimately pay for. It will probably have no more than a negligible effect on cosmetics safety, but it poses a serious threat to many businesses especially those making natural products, those supplying natural ingredients, and the farmers that grow the plants they come from.
SCA 2010 is especially onerous to small businesses (any corporation with a turnover of $7 million or less.) It requires each manufacturer to not only declare every constituent chemical of every ingredient on the label, but to also test each finished cosmetic to ensure that there is not even a trace amount of some toxic chemical that might have been formed during the making of the product. Most small personal care product businesses will not survive if SCA 2010 passes, a fact that may possibly be attractive to larger corporations.
However, the bill has been criticised by Lezlee Westine, President and CEO of the Personal Care Products Council, which represents the larger cosmetics companies. Her statement includes the following: “We are concerned that the Safe Cosmetics Act of 2010 as written is not based on credible and established scientific principles, would put an enormous if not impossible burden on FDA, and would create a mammoth new regulatory structure for cosmetics, parts of which would far exceed that of any other FDA-regulated product category including food or drugs. The measures the bill would mandate are likely unachievable even with the addition of hundreds of additional FDA scientists and millions more in funding and would not make a meaningful contribution to product safety.”
The Skin Deep database, mentioned in the first paragraph, gives an insight into the thinking of the CFSC and EWG. Skin Deep exaggerates toxicity by being selective in its reporting. For example, limonene, the major constituent of citrus essential oils, is flagged as being developmentally toxic in large doses. This is true, since when pregnant mice were fed 2,363 mg/kg limonene by stomach tube on days 7-12 of gestation, there was an increase in the number of fetuses with skeletal anomalies and delayed ossification (Kodama et al 1977).
However, what is not stated by Skin Deep is that in the same report, when pregnant mice were given a lower dose, 591 mg/kg/day, there was no developmental toxicity. The higher dose is equivalent to daily human ingestion of 5.7 oz of limonene, and the lower dose is equivalent to 1.4 oz. If ingestion of 1.4 oz per day for 6 days is known to be non-fetotoxic, then there is no reason to believe that the use of limonene in cosmetics is likely to be in any way hazardous during pregnancy; in fact, quite the opposite (especially since stomach tube feeding generally increases toxicity).
The Skin Deep page on limonene also mentions, under “cancer” that“one or more tests on mammalian cells show positive mutation results.” One reference is given. However, this ignores the fact that eleven other studies found no evidence of mutagenicity or genotoxicity for limonene (Anderson et al 1990, Connor et al 1985, Florin et al 1980, Haworth et al 1983, Myhr et al 1990, Pienta 1980, Sasaki et al 1989, Sekihashi et al 2002, Turner et al 2001, Watabe et al 1980, 1981), and two further studies reported antimutagenic effects (De Oliveira et al 1997, Kim et al 2001). This 13:1 “score” is part of the weight of evidence used to assess risk in toxicology.
Mutagenicity testing is used to identify substances that may be carcinogenic. However, 85% of substances that are not in fact carcinogenic test positive in a least one mutagenicity test (Kirkland et al 2005). These are “false positives”, and present no risk. The one study cited by Skin Deep for limonene is a false positive.
If you want to imply risk, it’s possible to do so simply by being selective about which facts you choose to report. Many small cosmetics manufacturers have become disenchanted with the manipulative ways of the CFSC and EWG. If they were sincere in caring about cosmetics safety they would welcome any pertinent opinions and facts, but they don’t. They either ignore or stridently oppose anything that does not accord with their fear-driven political agenda. It’s a shame, because a few of their concerns are genuine and well-founded, but their focus has become highly distorted.
I urge you to oppose the Safe Cosmetics Act 2010. Here are some steps you can take.
