Are botanics skin care products sold in boots actually produced by boots? where can i find info re producer?

I've looked at the packaging and it merely has Boots head office address on. It doesn't say 'produced for' so the products may be made in house. The only way to find out, I guess, is by asking Boots - I've looked at their website and that isn't very forthcoming. Some ethical retailers, most notably the Co-op, do say they are prepared to disclose the manufacturer of own brand products - Boots may be the same.
