What I received were two containers of very hazy, slightly yellow soaps with white swirly parts in them. NOTHING like the clear soap in the description photo. Maybe it is a great soap but this is far away from what I expected/ordered. Disappointed.

Not clear as shown in pictures

I came to this company due to it being semi local(same state) and pricing is affordable-as I was previously using another soap supplier that raised prices astronomically with shipping taking forever to receive. However, this soap base is NOT clear as shown in listing pics(its very hazy) and seems to always produce a dew/sweat. I make alot of kids soap favors and need CLEAR soap. I just received an order of a different "clear" soap base-let's hope it turns out clearer than before. Both appear to look identical in the box upon opening, for comparison so not sure why one says clear-they both appear to have that same hazy appearance. Shipping is expensive even when buying in bulk. A free fragrance oil is offered and smells great...however in my last order (just received today) there was NO free sample. Last order it was hiding in the shipping peanuts within the box.
Suggestion: send the free sample if you advertise it please and place it in a bag we can see easily. Shouldn't have to dig thru and remove all these 25lb cases and shipping foam/peanuts to find the small bottles of oils. Opened all cases and remove all shipping materials-did not receive "this free sample."
Shipping speed is awesome and I'll definitely order again.

Good base, but

A good soap base with nice lather that takes color well. However, despite storing it in the same way as my other soaps, it has very bad glycerin dew.

Love and always buying!

I use this soap base regularly and it is amazing. You can feel the moisture from the soap cause its slippery and it lasts for a good minute. Definitely higher quality soap that I keep coming back for!

Great product! I use it to make loofah soaps and they come out perfect. Low sweat, very clear and great fragrance lift. I just placed my third order.
