Rinses beautifully without drying or residue.
Scent: Rosewater (2 Pack)
The people who post videos of the refill soap being "pure water" apparently don't realize the soap also needs the FOAMING soap dispenser in order to turn this soap into foaming soap. God Bless America!
Yes, these items almost always leak when shipped, but usually not enough to return the item.
The best scents are Lemon, Desert Rose, Peppermint, and Rosewater.
I have been using these lightly scented foaming soaps for almost two decades.
They clean and rinse beautifully with no residue. Perfect for my OCD.
They never dry my hands out in the winter, regardless of how many times I wash.
The refill bottles are usually an excellent value when on sale. Highly recommended!
This foaming soap specifically needs a foaming soap dispenser. It specifically says that on the back of the package. For those complaining it’s a liquid and stays liquid, perhaps you’re using just a regular pump container.

Great for sensitive skin
Scent: Rosewater (2 Pack)
There is a lot of hand washing in our house and one kid was getting chapped hands from every soap. On a mission to discover the perfect soap, this one came out on top. It’s lightweight and easy to rinse off, moisturizing without leaving a greasy feeling, smells nice, and a little goes a long ways. It works great in every foam dispenser we have tried. Skin is healed and clean.

Botana oil for hair growth still waiting for results
6/2/2026 :There’s really no smell it moisturizes your hair. The ingredients are not damaging to my hair or scalp. There’s no greasiness. As far as the hair growth part of it I’m still waiting to see results and if or when I will update, but I would try it I mean, whatever we got to lose, but our hair and that I don’t mean that in a bad way, I’m being serious..
