Causes allergic contact dermatitis.

Butylated Hydroxytoluene (BHT)
Causes allergic contact dermatitis. Contains toluene.
See Toluene

Cationic surfactants
These chemicals have a positive electrical charge. They contain a quaternary ammonium group and are often called "quats". These are used in hair conditioners, but originated from the paper and fabric industries as softeners and anti-static agents. In the long run they cause the hair to become dry and brittle. They are synthetic, irritating, allergenic and toxic, and oral intake of them can be lethal.

Cocoyl Sarcosine
See Nitrosating agents

Cyclomethicone
See Silicone derived emollients

DEA (diethanolamine), MEA (Monoethanolamine), & TEA (triethanolamine)
Often used in cosmetics to adjust the pH, and used with many fatty acids to convert acid to salt (stearate), which then becomes the base for a cleanser. TEA causes allergic reactions including eye problems, dryness of hair and skin, and could be toxic if absorbed into the body over a long period of time.

These chemicals are already restricted in Europe due to known carcinogenic effects. Dr. Samuel Epstein (Professor of Environmental Health at the University of Illinois) says that repeated skin applications . . . of DEA-based detergents resulted in a major increase in the incidence of liver and kidney cancer.

See Nitrosating agents

From Material Safety Data Sheet (MSDS):

Ethoxylated surfactants
Ethoxylated surfactants are widely used in cosmetics as foaming agents, emulsifiers and humectants. As part of the manufacturing process the toxic chemical 1,4-dioxane, a potent carcinogen, is generated.

On the label, they are identified by the prefix "PEG", "polyethylene", "polyethylene glycol", "polyoxyethylene", "-eth-", or "-oxynol-".

See 1,4-Dioxane

FD&C Colour Pigments
Synthetic colours made from coal tar. Contain heavy metal salts that deposit toxins onto the skin, causing skin sensitivity and irritation. Animal studies have shown almost all of them to be carcinogenic.

Formaldehyde
Formaldehyde is a known carcinogen (causes cancer). Causes allergic, irritant and contact dermatitis, headaches and chronic fatigue. The vapour is extremely irritating to the eyes, nose and throat (mucous membranes).

See Nitrosating agents

Fragrance
Fragrance on a label can indicate the presence of up to four thousand separate ingredients, many toxic or carcinogenic. Symptoms reported to the USA FDA include headaches, dizziness, allergic rashes, skin discoloration, violent coughing and vomiting, and skin irritation. Clinical observation proves fragrances can affect the central nervous system, causing depression, hyperactivity, and irritability.

Liquidum Paraffinum
Liquidum Paraffinum is an exotic sounding way to say mineral oil (!!) See Mineral Oil

MEA compounds
See Nitrosating agents

Methylisothiazolinone and Methylchloroisothiazolinone
Both cause cosmetic allergies

Mineral Oil
Petroleum by-product that coats the skin like plastic, clogging the pores. Interferes with skin's ability to eliminate toxins, promoting acne and other disorders. Slows down skin function and cell development, resulting in premature aging. Used in many products (baby oil is 100% mineral oil!) Any mineral oil derivative can be contaminated with cancer causing PAH's (Polycyclic Aromatic Hydrocarbons). Manufacturers use petrolatum because it is unbelievably cheap.

Nitrosating Agents
The following chemicals can cause nitrosamine contamination, which have been determined to form cancer in laboratory animals. There are wide and repeated concerns in the USA and Europe about the contamination of cosmetics products with nitrosamines.

Paraben preservatives (methyl, propyl, butyl, and ethyl)
Used as inhibitors of microbial growth and to extend shelf life of products. Widely used even though they are known to be toxic. Have caused many allergic reactions and skin rashes. Highly toxic.

From Material Safety Data Sheet (MSDS):
EMERGENCY overview:
WARNING! HARMFUL IF SWALLOWED OR INHALED. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. MAY CAUSE ALLERGIC SKIN REACTION.

Paraffin wax/oil
Paraffin Wax is mineral oil wax. See Mineral Oil

Polyethylene Glycol (PEG) compounds
Potentially carcinogenic petroleum ingredient that can alter and reduce the skin's natural moisture factor. This could increase the appearance of aging and leave you more vulnerable to bacteria. Used in cleansers to dissolve oil and grease. It adjusts the melting point and thickens products. Also used in caustic spray-on oven cleaners. See Ethoxylated surfactants

Potassium Coco Hydrolysed Collagen
See Anionic Surfactants

Propylene/Butylene Glycol
Propylene glycol (PG) is a petroleum derivative. It penetrates the skin and can weaken protein and cellular structure. Commonly used to make extracts from herbs. PG is strong enough to remove barnacles from boats! The EPA considers PG so toxic that it requires workers to wear protective gloves, clothing and goggles and to dispose of any PG solutions by burying them in the ground. Because PG penetrates the skin so quickly, the EPA warns against skin contact to prevent consequences such as brain, liver, and kidney abnormalities. But there isn't even a warning label on products such as stick deodorants, where the concentration is greater than in most industrial applications.

From Material Safety Data Sheet (MSDS):
Health Hazard Acute And Chronic

INHALATION: May cause respiratory and throat Irritation, central nervous system depression, blood and kidney disorders. May cause Nystagmus, Lymphocytosis.

SKIN: Irritation and dermatitis, absorption.

EYES: Irritation and conjunctivitis.

INGESTION: Pulmonary oedema, brain damage, hypoglycaemia, intravascular hemolysis. Death may occur.

PVP/VA Copolymer
A petroleum-derived chemical used in hairsprays, wavesets and other cosmetics. It can be considered toxic, since particles may contribute to foreign bodies in the lungs of sensitive persons.

Quaternium-7, 15, 31, 60, etc
Toxic, causes skin rashes and allergic reactions.

See Nitrosating agents

From Material Safety Data Sheet (MSDS):
SKIN: PROLONGED OR REPEATED EXPOSURE MAY CAUSE SKIN IRRITATION. MAY CAUSE MORE SEVERE RESPONSE IF SKIN IS DAMP.

MAY BE A WEAK SKIN SENSITIZER IN SUSCEPTIBLE INDIVIDUALS AT GREATER THAN 1% IN AQUEOUS SOLUTION.

Rancid Natural Emollients
Natural oils used in cosmetics should be cold pressed. The refined vegetable oils found on supermarket shelves and many health food stores which lack colour, odour and taste are devoid of nutrients, essential fatty acids, vitamins and unsaponifiables - all valuable skin conditioning agents! They also contain poisonous "trans" fatty acids as a result of the refining process.

Another important factor to consider with creams made from plant oil is the use-by date. The most beneficial plant oils (like rosehip, borage and evening primrose oils) are polyunsaturated, which means they oxidise and go rancid fairly quickly (about 6 months). Most off-the-shelf cosmetics have a shelf life of three years. Rancid oils are harmful, they form free-radicals, which damage and age your skin.

Silicone derived emollients
Silicone emollients are occlusive - that is they coat the skin, trapping anything beneath it, and do not allow the skin to breathe (much like plastic wrap would do.)

Recent studies have indicated that prolonged exposure of the skin to sweat, by occlusion, causes skin irritation. Some synthetic emollients are known tumour promoters and accumulate in the liver and lymph nodes. They are also non-biodegradable, causing negative environmental impact.

Sodium Cocoyl Sarcosinate
See Anionic Surfactants

Sodium Laureth Sulfate (SLES) Ammonium Laureth Sulfate (ALES)
When combined with other chemicals, SLES and ALES can create nitrosamines, a potent class of carcinogens. It is frequently disguised in semi-natural cosmetics with the explanation "comes from coconut".

See Anionic Surfactants
See Ethoxylated surfactants
See Nitrosating agents

From Material Safety Data Sheet (MSDS):
WARNING! CAUSES SKIN AND EYE IRRITATION! AVOID CONTACT WITH EYES, SKIN AND CLOTHING. THE MATERIAL WAS CLASSIFIED AS A MODERATE TO SEVERE EYE IRRITANT.

Sodium Lauroyl Sarcosinate
See Anionic Surfactants

Sodium Lauryl Sulfate (SLS) Ammonium Lauryl Sulfate (ALS)
Used in car washes, garage floor cleaners and engine degreasers - and in 90% of products that foam.

Animals exposed to SLS and ALS experience eye damage, central nervous system depression, laboured breathing, diarrhoea, severe skin irritation, and even death.

Young eyes may not develop properly if exposed to SLS and ALS because proteins are dissolved. SLS and ALS may also damage the skin's immune system by causing layers to separate and inflame. It is frequently disguised in semi-natural cosmetics with the explanation "comes from coconut".

Stearalkonium Chloride
A chemical used in hair conditioners and creams. Causes allergic reactions. Stearalkonium chloride was developed by the fabric industry as a fabric softener, and is a lot cheaper and easier to use in hair conditioning formulas than proteins or herbals, which do help hair health. Toxic.

See Cationic surfactants

Talc
Scientific studies have shown that routine application of talcum powder in the genital area is associated with a three-to-fourfold increase in the development of ovarian cancer.

TEA (Triethanolamine) Laureth Sulfate
