Do any Avon products contain shellfish or shellfish by product?

I have a customer who is allergic to shellfish and shellfish byproducts, and she cant use anything that might have these ingredients. I have called the help desk at the lab to try and find out, but no one can give me a definate answer. She wants to know just for future reference in case she orders something else from me. But the lab will only tell me if I have a actual product that she ordered. please advise!
