The worst offenders

Toxic Ingredients
How safe are the ingredients used in your current brand of skin care products? How certain are you that they do not contain chemicals that could be harmful to you and/or your children?
If you are not sure, I have listed some of the worst offenders below. This information has been sourced from Material Safety Data Sheets (or MSDS).

Alcohol, Isopropyl (SD-40)
A very drying and irritating solvent and dehydrator that strips your skin's natural acid mantle, making us more vulnerable to bacteria, moulds and viruses. It is made from propylene, a petroleum derivative. It may promote brown spots and premature aging of skin.

Anionic Surfactants
They may be contaminated with nitrosamines, which are carcinogenic. Surfactants can pose serious health threats. They are used in car washes, as garage floor cleaners and engine degreasers - and in 90% of personal-care products that foam.
Also.. Sodium Lauryl Sulfate (SLS), Sodium Laureth Sulfate (SLES), Ammonium Lauryl Sulfate (ALS), Ammonium Laureth Sulfate (ALES), Sodium Methyl Cocoyl Taurate, Sodium Lauroyl Sarcosinate, Sodium Cocoyl Sarcosinate, Potassium Coco Hydrolysed Collagen, TEA (Triethanolamine) Lauryl Sulfate, TEA (Triethanolamine) Laureth Sulfate, Lauryl or Cocoyl Sarcosine, Disodium Oleamide Sulfosuccinate, Disodium Laureth Sulfosuccinate
Disodium Dioctyl Sulfosuccinate etc

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.

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. Harmful if swallowed or inhaled. Causes irritation to skin, eyes and respiratory tract. May cause allergic skin reaction. Symptoms include redness, itching, and pain.

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.
Also… Dimethicone, Dimethicone Copolyol, Cyclomethicon
