There are pigments on the market that claim to be either organic or hypoallergenic. The problem is that formulations are a closely guarded secret so you never know exactly what you're getting, although there seems to be some improvement in that area. If a particular shop doesn't use the ink you want you should be able to have it stocked for you, which of course you'd have to pay for but I wouldn't think that much more. If the shop refused to work with you then that's a shop to avoid.
