So I would like to know. Do u sell this by Full size bottle?

Hi Nancy, Thanks for your question! We do not currently have this product in a retail size bottle.

I love this product. It would be great (environmentally) to buy it in bulk, and refill the smaller bottles. Is that an option at some point?

These bottles are too small to be sanitized before refilling, however please check out our refillable and reusable Gallon sets with 10 oz. refillable pump bottles. The sets also have an option to come with a heavy duty wall bracket that attaches to a shower wall for the 10 oz. bottles to fit in. https://www.amazon.com/Botanics-1-Shoppe-Amenities-AirBnB-Vacation/dp/B07YQ7HGCZ with bracket: https://www.amazon.com/Botanics-1-Shoppe-Amenities-AirBnB-Vacation/dp/B07YQCLX4T?th=1

I have a sensitivity to sulfates and this does not bother me. Plus it doesn’t say it has sulfates.. I cannot say with certainty that there aren’t any just that it doesn’t bother me.
