Thank you so much for the support and advice! I would definitely only use BPA free water/soda bottles (we try to avoid BPA in our household anyway,) and try to find a way to, if possible, convert it into a pump bottle
I was hoping if the products worked out, I could sell them on Etsy and donate 40% of the profits to charity

If anyone would like to test, that would be wonderful! Right now, I have formulas for a cleansing conditioner, rinse out (or leave-in,) curl gelly, skin cleanser, and skin lotion. Again, thank you so much for the feedback!
