DEA: An abbreviation for Diethanolamine. See below.
Diethanolamine (DEA):Used in cosmetics as an emulsifying agent. Considered to be highly toxic when used in industrial applications, and has been proven to cause cancer when applied to the skin of rats. And yet, this ingredient, and its derivatives, is permitted to be used in cosmetic products at limited levels. Derivative ingredients may appear as cocamide DEA or lauromide DEA. DEA can be found in over 600 cosmetic and personal care products.
Diethylene Glycol: This chemical is actually a solvent and is used to enhance the absorption of other ingredients in skin creams. Not usually irritating to the skin, but can be fatal if swallowed.

Ethyl Hexanediol:Used as a solvent for manufacturing cosmetics. Skin application caused birth defects in laboratory animals.
Ethylene Dichloride (EDC): A solvent used in manufacturing cosmetics. Also used for manufacturing vinyl chloride, paint, varnish, and as a lead scavenger in antiknock gasolines. In cancer testing, the National Cancer Institute found this compound caused stomach cancer and vascularized cancers of multiple organs. It also produced cancers beneath the skin in male rats, and female rats developed mammary cancers.
Ethylene Glycol: A chemical solvent used for manufacturing cosmetics. Also used as antifreeze. Can absorb twice its weight in water. Toxic when ingested, causing central nervous system depression, vomiting, drowsiness, coma, respiratory failure, kidney damage, and possibly death.
Ethylenediamine Tetraacetic Acid (EDTA): Widely used by cosmetic manufacturers as a sequestering preservative. It may be irritating to the skin and mucous membranes and can cause allergies such as asthma and skin rashes.
Euxyl K 400: This is one of the newer, more modern preservatives used in skin creams. There are increasing reports from physicians regarding patients who are sensitive to it, and physicians are being encouraged to test it with their patients for allergic contact dermatitis.
Fibroin Copolmyer: A synthetic polymer used as a binder and film-former in dyes, adhesives, permanent-press fabrics and skin creams. Toxic by skin absorption.

Methylparaben: See parabens.
Methylisothiazolinone and/or Methylchloroisothiazolinone: Used in cosmetics as a broad spectrum preservative. It is highly toxic in rats and rabbits orally but only moderately toxic when applied to the skin.
Mineral oil: Also known as White Oil. This is a petroleum by-product which can clog your pores. Mineral oil is a mixture of liquid hydrocarbons, and not particularly beneficial for any skin type, and yet, because it is cheap and stable from spoilage, is widely used in many skin care products.
Morpholine: A inexpensive solvent used as a emulsifier in cosmetics. Also used as a insecticide and fungicide. May cause kidney and/or liver injury.
Nickel Sulfate: Used in hair dyes and astringents. Causes vomiting when swallowed. Its systemic effects include blood vessel, brain, and kidney damage and nervous depression.
Nitrobenzene: Also known as Essence of Mirabane. Used as a cheap scent in inexpensive cosmetic products. Also used as a solvent for manufacturing metal polish, shoe polish and many other products. Rapidly absorbed through the skin. Poisonous. Exposure may cause headaches, drowsiness, nausea, vomiting, lack of oxygen in the blood (methemoglobinemia), and cyanosis.
Parabens: Butylparaben, methylparaben and propylparaben are the most commonly used cosmetic preservatives in the United States. They are very inexpensive and easy to use, which makes them very desirable for manufacturers. Paraben preservatives can be found in approximately 20,000 personal care products, including "natural" products. Methylparaben can cause allergic reactions and propylparaben can cause contact dermatitis. However, more importantly, recent studies have shown that parabens can also penetrate the skin and seep into the tissue. This concerns researchers because parabens have been shown to be able to mimic the action of estrogen, which can encourage breast cancer cell growth. In a recent U.K. study, 20 breast tumors were analyzed and high concentrations of parabens were found in 18 of the 20 tumors. From the research it is not possible to determine whether the parabens actually caused the tumors, but this new information does raise many concerns.
PEG: This is an abbreviation for polyethylene glycol. Available in many molecular weights, such as PEG-4 or PEG-350. The number stands for liquidity. The higher the number, the harder the composition. Widely used for cosmetic cream bases as a binder, plasticizing ingredient, solvent and softener. Also used for hair straighteners, antiperspirants and polish removers.
Petrolatum: This chemical lubricant is made using methane and olefin semisolid hydrocarbons which are derived from petroleum. Used to make skin creams feel smoother. Individuals having hypersensitive skin may have allergic reactions to petrolatum, but is generally nontoxic.
Phenol: Also known as Carbolic Acid. Used in creams and lotions for its disinfectant and anesthetic properties. Derived from coal tar. Ingestion of even small amounts may cause nausea, vomiting, and circulatory collapse, paralysis, convulsions, coma, and greenish urine as well as necrosis of the mouth and the gastrointestinal tract. Death results from respiratory failure. Fatalities have been reported from ingestion of as little as 1.5 grams.
Polyacrylamide: Used by the cosmetic industry as a thickening ingredient for creams. Also used for manufacturing plastics and adhesives. This chemical is highly toxic and irritating to the skin. Causes central nervous system paralysis. Can be absorbed through unbroken skin.
Polybutene: Used in cosmetics as a plasticizer. Derived from petroleum. Also used for manufacturing adhesives. May asphyxiate. Considered safe for cosmetic use as currently used.
Polyethylene: Widely used in creams and lotions. No known skin toxicity, but implants in rats caused cancer. Ingestion of large oral doses has produced kidney and liver damage.
Polyvinylpyrrolidone: A plastic resin used as a carrier ingredient in emollient creams, and as a softener in other cosmetic products. Ingestion may cause gas and fecal impaction or damage to the lungs and kidneys and if ingested, may last in the system for months to a year.
Potassium Hydroxide: Used as an emulsifier in creams and lotions. Extremely corrosive, and if ingested may cause violent pain, bleeding, collapse, and death. When applied to the skin of mice, moderate dosages causes tumors.
Propylene Glycol (PG): Propylene Glycol serves as a Humectant - a substance that helps to retain moisture content. It is also a wetting agent and solvent, so it is used by many cosmetic manufacturers to facilitate the process of dissolving and combining ingredients. Propylene Glycol is widely used in skin cream, and many other personal care products. Propylene Glycol is also one of the key ingredients in embalming fluid, anti-freeze, brake fluid, hydraulic fluid, de-icer, paints and floor wax. The Material Safety Data Sheet (MSDS) for Propylene Glycol clearly states: "Implicated in contact dermatitis, kidney damage and liver abnormalities; Can inhibit skin cell growth in human tests, and can damage cell membranes causing rashes, dry skin and surface damage." The MSDS also cautions: Acute Effects: "May be harmful by inhalation, ingestion or skin absorption. May cause eye irritation, skin irritation. Exposure can cause Gastrointestinal disturbances, Nausea, Headache, Vomiting and Central Nervous System depression." Propylene Glycol is toxic, and it will actually retards your skin's ability to maintain normal cellular regeneration.
In 1992, the FDA proposed a ban on Propylene Glycol in louse-killing products because it has not been shown to be safe and effective for its stated claims, yet, Propylene Glycol is allowed to be used in cosmetics in concentrations up to 50%. Animals who were experimentally exposed (not by us) to Propylene Glycol suffered all of the above symptoms, including mild to profound central nervous system depression as well as heart arrhythmia, respiratory failure, narcosis (profound stupor), growth depression, decreased blood pressure, and even death. The recommended method of storage for undiluted propylene glycol is in an explosion-proof refrigerator.
Quaternarium-15: A water-soluble antimicrobial ingredient that is active against bacteria. It is a formaldehyde releaser, and is the number-one cause of dermatitis from preservatives, according to the American Academy of Dermatology's Testing Tray results.
Sodium Dehydroacetate: A cosmetic preservative. If ingested can cause impaired kidney function. Large doses can cause vomiting, ataxia, and confusion. There are no apparent allergic skin reactions and it is considered safe as a cosmetic ingredient.
Sodium Dodecylbenzene Sulfonate:A widely used detergent in skin creams and bath products. If swallowed will cause vomiting. Some animal studies revealed kidney, intestinal and liver damage when given orally. Considered to be a safe cosmetic ingredient.
Sodium Hydroxide: A common ingredient used in household liquid drain cleaners and now, skin creams. Ingestion causes vomiting, prostration, and collapse. Inhalation causes lung damage.
SLS: Abbreviation for Sodium Lauryl Sulfate. See Below.
Sodium Lauryl Sulfate: SLS is outstanding for cleaning grease off concrete, or de-greasing a car engine. Therefore, it is of course only logical that it should also be used in toothpaste and face creams. SLS is known to causes eye irritations, skin rashes, hair loss, scalp scurf similar to dandruff, and many other allergic reactions. This is a industrial strength chemical and is frequently disguised in pseudo-natural cosmetics with the parenthetic explanation "comes from coconut".
Stearalkonium Chloride: A chemical developed for the fabric industry to promote fabric softness, and now used in face creams. Toxic.
Synthetic Colors: Usually labeled as FD&C or D&C, followed by a color and a number. Example: FD&C Red No. 6 / D&C Green No. 6. Many synthetic colors are believed to be carcinogenic (cancer-causing agents).
Synthetic Fragrances:The synthetic fragrances used in cosmetics can have as many as 200 ingredients. There is no way to know what the chemicals are, since the label will simply say "Fragrance". Some of the problems caused by these chemicals are headaches, dizziness, rash, hyperpigmentation, violent coughing, vomiting, skin irritation, and the list goes on and on.
Trichloroethane: Used in cosmetics as a solvent and for de-greasing. Can be absorbed through the skin. Inhalation and ingestion can cause symptoms ranging from vomiting to death.
Triclocarban: Also known as Trichlorocarbanilide and TCC. A cosmetic ingredient used for killing bacteria. In May of 1983 it was discovered that test results regarding this cosmetic ingredient were falsified, and lab tests which resulted in rat deaths were not being reported. Information regarding the pathology relating to the rat deaths were also not reported.
TEA: The abbreviation for Triethanolamine. See below.
Triethanolamine: A chemical used in cosmetics to adjust the pH, and also used as an emulsifier. May cause allergic reactions, including eye problems, dryness of skin, and could be toxic if absorbed into the body over a long period of time. In Italy, at the University of Bologna, it was discovered that this chemical ingredient was the most frequent sensitizer among the common emulsifiers used in cosmetics. Also used as a chemical coating to preserve fresh fruit. Concentration should not exceed 5% when used in products that come in contact with the skin.
Trioctanoin: Derived from coconut, a mildly toxic, oily, preservative. Known to cause skin irritation, and known to cause mutations in experimental animals.
Tripolyphosphate: Used as a water softener and emulsifier. May cause esophageal stricture and violent vomiting if swallowed.
