Hun, I think it's fantastic that you took the time to write to them.

I have to admit that I have heard many conflicting stories about palm oil, so I'm not sure what's true and what's not. But I do think that most products have some harm somewhere along the line so it's hard to be totally ethical. I guess it comes down to the line that you draw for yourself. If the product fits within your level of comfort, then go for it. If you have doubts, perhaps you could investigate other products claiming to be ethical to see if they raise as many doubts. You might end finding a product you like better, that you feel happier using ethically. Or you could try and contact an environment or ethical living agency and see if they can offer you more information. Good luck!!
