What is it?
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.
The following chemicals can cause nitrosamine contamination in conjunction with a secondary or tertiary amine:
2-bromo-2-nitropropane-1,
3-diol,
Ammonium Laureth Sulfate
Ammonium Lauryl Sulfate
DEA (Diethanolamine) compounds (Secondary Amine-the main culprit)
Formaldehyde (All Aldehydes)
Hydrolyzed Animal Protein
Hydroxymethylsarcosine
Imidazolidinyl Urea
MEA (Monoethanolamine) compounds (Primary Amine)
Sodium Lauryl Sulfate
Sodium Laureth Sulfate
TEA (Triethanolamine) compounds (Tertiary Amine)
Quaternium-7, 15, 31, 60, etc
When these are combined with certain ingredients, this is how they form nitrosamines
