先摘几段关于硅和增泡剂的说法

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 known as:
Dimethicone
Dimethicone Copolyol
Cyclomethicone

增泡剂

1) Anionic Surfactants

Anionic refers to the negative charge these surfactants have. 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 known as:
- Sodium Lauryl Sulfate (SLS) 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.
- 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

2) 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-.

3) 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.

Also known as:
- 2-bromo-2-nitropropane-1,3-diol
- Cocoyl Sarcosine
- DEA compounds
- Imidazolidinyl Urea
- Formaldehyde
- Hydrolysed Animal Protein
- Lauryl Sarcosine
- MEA compounds
- Quaternium-7, 15, 31, 60, etc
- Sodium Lauryl Sulfate
- Ammonium Lauryl Sulfate
- Sodium Laureth Sulfate
- Ammonium Laureth Sulfate
- Sodium Methyl Cocoyl Taurate
- TEA compounds
