Have you read the ingredient label on your shampoo lately?

How about the label on that bottle of bath gel?

Or toothpaste?

Or moisture cream?

If you have, you most certainly ran into a practically endless list of hard-to-pronounce, even harder-to-decipher chemical names. Have you ever wondered if all those chemicals are really safe?

If you are worried about the ill effects that daily doses of chemicals in your personal care products can have on your health, you have good reason for concern. The list of potentially harmful ingredients found in our everyday products is staggering. There are literally thousands of chemical compounds formulated into the personal care products, cleaning supplies and processed foods that we use and consume daily.

What do these ingredients do? What kinds of reactions can they cause? What happens inside our bodies when these chemicals build up over decades of use? What happens when they interact with one another? And what is the FDA doing about it? 

What Happens to Petrochemicals in Our Body?

The truth is, the petrochemicals found in most shampoos and cosmetics can be absorbed through the scalp and skin and, over time, accumulate in the organs and tissues. This accumulation may result in mounting brain, nerve, and liver damage, according to a recent government study (Matthew et al., 1995).

The human body can normally do a pretty good job of keeping us functioning and healthy. But the increasing onslaught of chemicals the body has to deal with during the last 50 years or more is just too much, too fast. How can we expect our body to deal with so many foreign substances all at once?

For example, take Aluminum. To reach the brain, aluminum must pass the blood-brain barrier, a complex system that filters the blood to prevent toxic elements from entering the brain. This filtration system developed over a long period of time for our protection. Elemental aluminum doesn't normally pass through this barrier, but the aluminum compounds found in many personal care products pass through easily!

Even Aspirin, long considered harmless, can inadvertently become a serious toxin. Because Aspirin is often buffered with aluminum hydroxide or glycinate, if orange juice is ingested at about the same time as the Aspirin, the citric acid in the juice transforms the aluminum hydroxide or glycinate compounds into aluminum citrate -- which is 5 times more likely to end up in the brain.

And many consumable products besides Aspirin contain citric acid.  Now, if the aluminum in food combines with maltol, a sweetener used in many baked goods, its capacity to pass the blood-brain barrier increases by as much as 90 times! How can you possibly know when you might use a product that will react negatively with another you just used?

The Dangers of DEA  
One of the most common - and potentially toxic - compounds commonly found in personal care products is DEA (diethanolamine). Formulated into soaps, detergents and surfactants, it is found in over 600 home and personal care products. The shampoo and soap you use probably includes it.

Belonging to a class of chemicals known as alkanolamines (which includes monoethanolamine and triethanolamine or TEA), DEA has been linked with kidney, liver, and other organ damage according to several government-funded research studies, and has been proven to cause cancer in rats when applied to the skin.

According to a 1995 study funded by the National Institute of Environmental Health Sciences, DEA has low acute toxicity but significant cumulative toxicity. As DEA collects in the tissues, it spurs an accumulation of abnormal phospholipids that can lead to mounting tissue and nerve damage and premature death (Matthew et al., 1995).

Another study found that oral and topical application of DEA in rodents resulted in anemia, kidney degeneration, and nerve damage to the brain and spinal cord (Melnick et al., 1994). Even more disturbing was that several animals died before the study ended. The authors concluded, "DEA is toxic at multiple organ sites in rats, either by oral exposure in the drinking water or by topical application."

In 1995, Steinman and Epstein stated, "The FDA accepts that the presence of DEA and TEA in cosmetics can pose a significant consumer health threat. In the 1970s it published a notice in the Federal Register in which it  urged the industry to remove these products from cosmetics."

In spite of this, DEA is still one of the most common cosmetic and hair care ingredients.  More Petrochemicals and Toxins That Have Found Their Way Into Your Personal Care Products  Many other potentially toxic petrochemicals are found in commercial personal care products.

Some quaternium compounds, like behentrimonium chloride, can be fatal if ingested and can cause necrosis (tissue death) of the mucous membranes in concentrations as low as one percent. Moreover, some synthetic colors, such as FD & C Blue No. 1, are suspected carcinogens (cancer-causing agents).

Other studies have shown that the popular food additive, Yellow Dye #5, can instigate asthmatic breathing.  Here are a few other ingredients commonly found in shampoo, conditioner, and soap:

Propylene Glycol (also called Propanediol) - A colorless, viscous, hygroscopic liquid used in anti-freeze solutions, in brake and hydraulic fluids, as a de-icer, and as a solvent. It's even found in some pet foods, processed foods and cosmetics, toothpastes, shampoos, deodorants and lotions. 

It is implicated in contact dermatitis, kidney damage and liver abnormalities. It can inhibit skin cell growth in human tests, can cause gastro-intestinal disturbances, nausea, headache and vomiting, central nervous system depression and can damage cell membranes causing rashes, dry skin and surface damage (according to the Material Safety Data Sheet). 

 Sodium Lauryl Sulfate (SLS) or Sodium Laureth Sulfate (SLES)- Used as a surfactant to break down the surface tension of water. It is used in concrete floor cleaners, engine degreasers, car wash detergents, and just about every soap and shampoo on the market. And yet, according to the Journal of the American College of Toxicology; Vol. 2, No. 7, l983, SLS is a mutagen. Insufficient amounts, it is capable of changing the information in genetic material found in cells! It has been used in studies to induce mutations in bacteria. 

Found in almost all shampoos, SLS actually corrodes hair follicles and impairs the ability to grow hair! It denatures protein, and even impairs proper structural formation of young eyes, creating permanent damage.

SLS can damage the immune system and can cause separation of skin layers, causing inflammation to the skin. If it interacts with other nitrogen bearing ingredients, Carcinogenic Nitrates can form as a result. Behentrimonium Chloride, Guar Hydroxypropyltrimonium Chloride, Linoleamidopropyl PG-Dimonium Chloride Phosphate - These are toxic ammonium compounds. Ingestion can be fatal.

Concentrations as low as 0.1% can be irritating to eyes and cause necrosis (tissue death) of mucus membranes. Stearamidopropyl Dimethylamine - Synthetic surfactant; can cause eye irritation and dermatitis. And these are just the tip of the iceberg!

We expose ourselves day after day, often all day and night long (through cosmetics, scents and lotions), to these toxic ingredients - and then we wonder why cancer rates are soaring!  Way back in 1938, the FDA published guidelines regarding suitable levels of ingredients in products for human use.

But little was known then about long-term exposure. Many substances considered safe then are being proven unsafe. And in the meantime, hundreds more toxic compounds have been added to our lives.

 Is the cosmetic industry concerned? Hardly. Their response typically sounds like this, "...has not been proven...in humans" or "our products are formulated within strict FDA guidelines" or "more studies are needed."  I'm certain there will be more studies - but many years will pass. We all know debate and legislation progresses at a snail's pace. And the health consequences associated with continued use will escalate.

 Even when the FDA has all the scientifically valid, conclusive proof they need, they may only be able to require warning labels.  As a matter of fact, warning labels have been getting stronger and more visible lately. Have you noticed the warning on your toothpaste? Here's one straight off a popular brand, "Keep out of the reach of children under 6 years of age. In case of accidental ingestion, seek professional assistance or contact a Poison Control Center immediately."

I don't know about you, but I find this very alarming. The very fact that such a strong warning is printed on toothpaste tells me there is a good reason for it! And how many children do you know under the age of 6 who can refrain from swallowing toothpaste?

Hair Dye and Breast Cancer

Women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer, according to a new study by the National Institutes of health. After examining medical data and lifestyle surveys from 46,709 women ages 35 to 74, researchers found that white women who had used permanent hair dye in the previous year were 7% more likely to get breast cancer in the 8 year follow-up period. For black women the increased risk was 45%. Use of chemical hair straighteners was linked to an 18% higher breast cancer risk in both black and white women. Researchers don't know which of the five thousand chemicals found in hair products might be of concern, or why there is such a racial disparity. It could be that products designated for black women contain more of the cancer causing chemicals, or that differences in hair texture affect the amounts of dyes that are applied. Still the risk from these products seems relatively low, so far anyway, and scientists typically worry only when environmental exposures increase cancer risk by 100% or more.  

I am seriously wondering what the compounding effects are over time. 

“These risks are potentially important” in “Co author Alexandra White tells the New York times, but we know that a lot of different factors contribute to a women's risk of breast cancer."

My dad discovered that his hair dye was adding massive amounts of lead into his bloodstream. Most of us already know how deadly-toxic lead can be.

While bureaucracy moves along at a snail's pace, personal decisions about your health don't have to. It is ultimately up to you, the consumer, to make changes for the better in your own life. It's up to you to choose products that will truly enhance your life and your health rather than destroy it.
