Oxonius,
You're right, it would seem that the two companies have similar green philosophies. From the Caldrea safety page:

Caldrea products care for the most sacred spaces of all: our homes and ourselves. This is where we—and our children, pets and loved ones—live and breathe. And for this reason, safety is our number one concern.
Our products provide an effective alternative for people who are concerned about the effects of conventional cleaning and body care products. Our formulas combine long-trusted essential oils with leading-edge know-how to provide a safer experience for our customers.
