Amylase
Is indeed found in some laundry detergents. Novozeymes (sp?), amoung other chemical suppliers make this enzyme for inclusion in laundry products. My box of Persil "Sensitive" Megaperls lists amylase amoung other enzymes.
Once posted a link that listed all and sundry enzymes available for use in laundry products, and the list is not small.
Enzymes needed to be somehow "covered" after it was discovered workers in laundry product plants were coming down with various allergic reactions (skin, breathing, etc), from handling or breathing the stuff. This gave rise to the stories of persons having skin rashes from coming into contact with laundry washed in "bio" detergents.
While it is possible someone could have allergic reactions to laundry product residue (enzymes), the amount of enzymes used in laundry detergents is rather small, indeed a very small amount of total product at recommended doses.
It is easier to find out what is in European detergents due to labeling laws. As no such requirments are made in the United States, we can only go by vauge class descriptions , or MSDS information. Normally one only sees protease enzymes listed/spelled out as it can cause allergic reactions by inhalation or skin contact, owing to the fact much of the human body is made from protein.
