2. Methyl, Propyl, Butyl, and Ethyl Paraben — 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. Methyl paraben combines benzoic acid with the methyl group of chemicals. Highly toxic.

3. Petrolatum —  Petrolatum is mineral oil jelly, and mineral oil causes a lot of problems when used on the skin—it can produce photosensitivity (i.e., promotes sun damage), and it tends to interfere with the body's own natural moisturizing mechanism, leading to dry skin and chapping. You are being sold a product that creates the very conditions it claims to alleviate. Manufacturers use petrolatum because it is very cheap.

4. Propylene Glycol — Ideally this is a vegetable glycerine mixed with grain alcohol, both of which are natural. Usually it is a synthetic petrochemical mix used as a humectant. Has been known to cause allergic and toxic reactions.

5. 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.

6. Sodium Lauryl Sulfate — This synthetic substance is used in shampoos for its detergent and foam-building abilities. It causes eye irritations, skin rashes, hair loss, scalp scurf similar to dandruff, and allergic reactions. It is frequently disguised in pseudo-natural cosmetics with the parenthetic explanation "comes from coconut".

7. 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.

8. Synthetic Colors — The synthetic colors used to supposedly make a cosmetic "pretty" should be avoided at all costs, along with hair dyes. They will be 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. Synthetic colors are believed to be cancer-causing agents. If a cosmetic has them in it, don't use the cosmetic.

9. 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 on the label it 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. Advice: Don't buy a cosmetic that has the word "Fragrance" on the ingredients label.
