Toxic chemicals in the air we breathe, the food we eat and the personal care toiletries we use on our hair and skin may be contributing to the spiraling rate of cancer.

"The glossy images we're fed by the media hide a dangerous secret: Most of our toiletries, even the "natural variety", are made from the same harsh chemicals used for industry". (What Doctors Don't Tell You Vol 10 No7 10/99) |

What could be more healthy than a refreshing body wash, a nourishing shampoo, a minty fresh toothpaste and a moisturizing facial cream? Commercials, magazine advertisements and billboards bombard us with the message that soaping and scrubbing, exfoliating and moisturizing are only beneficial to our health. Yet the glossy images of well scrubbed individuals hide a dangerous secret: Too many of the toiletries and cosmetics we use are carcinogenic cocktails of hazardous waste. Most of the chemicals which go into our toiletries are no different from the harsh toxic chemicals used in industry. Far from enhancing health they pose a daily threat to it. For example, propylene glycol (PG) is a wetting agent and solvent used in make up, hair care products, deodorants and after shave. Its also the main ingredient in antifreeze and brake fluid. Similarly, polyethylene glycol (PEG), a related agent found in most skin cleansers, is a caustic used to dissolve grease... the same substance you find in oven cleaners. Isopropyl, an alcohol used in hair rinses, hand lotions and fragrances, is also a solvent found in shellac. What to watch out for
Sodium lauryl sulphate (SLS) used in toothpastes, shampoos and just about every personal cleansing solution, is a harsh detergent commonly used as an engine degreaser. Each of these ingredients readily penetrates the skin with potentially adverse consequences (see previous box) Some of the most dangerous chemicals we put on our bodies in the name of beauty belong to a family of hormone-disrupting chemicals, which are water soluble ammonia derivatives. DEA (diethanolamine), TEA (Triethanolamine) are almost always in products that foam: bubble bath, body washes, shampoos, soaps and facial cleansers. They are used to thicken, wet, alkalise and clean. While they are irritating to the skin, eyes and respiratory tract (Rev Environ Contam Toxicol, 1997; 149: 1-86) DEA, MEA and TEA are not considered particularly toxic in themselves. However once added to the product these chemicals readily react with any nitrites present to form potentially carcinogenic nitrosamines, such as NDEA (N-nitrosodiethanolamine). Of the three, MEA and DEA pose the greatest risk to human health. Prolonged exposure to these can alter liver and kidney function (J Am Coll Toxicol, 1983; 2: 183- 235) and even lead to cancer (Rev Environ Contam Toxicol, 1997; 149: 1-86). Nitrites get into personal care products in several ways. They can be added as anticorrosive agents, they can be released as a result of the degradation of other chemicals, specifically 2-nitro-1,3-propanediol (BNDP), or they can be present as contaminants in raw materials. Ingredients such as formaldehyde or formaldehyde-forming chemicals, or 2-bromo-2-nitropropane (also known as Bronopol) which can break down into formaldehyde.... can also produce nitrosamines. The long shelf life of most toiletries also increases the risk of creating a carcinogenic reaction. Stored for a long time at elevated temperatures, nitrates will continue to form in a product, accelerated by the presence of other chemicals, such as formaldehyde, paraformaldehyde, thiocyanate, nitrophenols and certain metal salts (Science, 1973; 182: 1245-6; J Nat Cancer Inst, 1977; 58:409;Nature, 1977; 266: 657-8; Fd Cosmet Toxicol, 1983; 21: 607-14) Inadequate and confusing labelling means that consumers may never know which products are most likely to be contaminated. However, in a recent Food and Drug Administration (FDA) report, approximately 42% of all cosmetics were contaminated with NDEA, with shampoos having the highest concentrations (National Toxicology Program, Seventh Annual Report on Carcinogens, Rockville, MD: US Department of Health and Human Services, 1994). In Europe, where more safeguards are in place regarding nitrosating agents, the picture is somewhat better. For instance, in Germany, after the Federal Health Office issued a request to eliminate all secondary amines (such as DEA) from cosmetics in 1987 a report confirmed that only 15 per cent of products tested were contaminated with NDEA (Eisenbrand, G, et al in O'neill, IK, et al [Eds}; N-Nitrosoalknolamines in cosmetics, Lyon: IARC, 1991). Manufactures insist that DEA and its relatives are "safe" in products designed for brief or discontinuous use or those which wash off. However there is evidence from both human and animal studies that NDEA can be quickly absorbed through the skin (J Nat Cancer Inst, 1981; 66: 125-7; Toxicol Lett, 1979; 4: 217-22). This argument also doesn't explain why these chemicals crop up regularly in body lotions and facial moisturisers, which are of course meant to stay on the skin for long periods of time. As far back as 1978, the International Agency for Research on Cancer (IARC) concluded that "Although no epidemiological data were available, nitrosodiethanolamine should be regarded for practical purposes, as if it were carcinogenic to humans" (IRAC, 1978; 17: 77-82). This position was reaffirmed nearly 10 years later. DYEING or DYING?????

In America in 1994, the National Toxicology Program similarly concluded in its Seventh Annual Report on Carcinogens that: "There is sufficient evidence for the carcinogenicity of N-nitrodiethanolamine in experimental animals." The report noted that of more than 44 different species in which NDEA compounds have been tested all have been susceptible (Lijinsky, W, Chemistry and Biology of N-Nitroso Comaounds, New York: Cambridge University Press, 1992).
Humans were unlikely to be the single exception said the paper.
The cosmetics industry's response to the problems of nitrosamine formation has been to put even more chemicals in their products in an attempt to slow or inhibit the formation of NDEA. These include ascorbic acid, sodium bisulfite, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), sodium ascorbate, ascorbyl palmitate and a-tocopherol. None has proved adequate to prevent nitrosamine formation (Cosmetics & Toiletries, 1994; 109: 53)
In 1996, the Cosmetics, Toiletries and Fragrance Association (Cosmetic Ingredient Review, Washington DC; 1996 CIR Compendium) stated: "These chemicals [Cocamide DEA, Lauramide DEA, Linoleamide DEA, and Oleamide DEA] should not be used as ingredients in cosmetic products containing nitrosating agents."
Nevertheless DEA, TEA and MRA continue to be widely used in a staggering variety of toiletries and cosmetics.
