I think Berghill is spot on. These companies won't tell you the exact ingredients as they would consider it a trade secret but if you were worried about it containing something in particular (such as neonicotinoids), they may be more happy to tell you that their product is free of it.
Edit: just saw your reply. I would only consider using horticultural soap in the garden. Maybe try a mixture of that and neem oil if you want to DIY.
