Product Overview

Cobalt tetroxide belongs to transition metal oxides, which are in powder form and generally appear gray black or black in color. Its molecular weight is 240.8, density is 6.11cm2/g, and melting point is 895 ¡ãC At room temperature, cobalt trioxide material is insoluble in water. When the temperature reaches above 900 ¡ãC cobalt trioxide (Co3O4) decomposes into cobalt trioxide (Co2O3) and cobalt oxide (CoO), and the final products will stabilize into CoO. Meanwhile, cobalt trioxide is also a p-type semiconductor and antiferromagnetic material with a bandgap width of 1.5 eV. Co3O4 is a spinel type oxide with a lattice parameter of approximately 0.809nm. There are three methods for preparing cobalt trioxide based on the physical state of the required cobalt source: solid-phase method, gas-phase method, and liquid-phase method.

Great product
Size: 25 Count (Pack of 6)
My favorite facial wipes. Gentle to your skin, no alcohol, no burning on the eyes! These wipes clean well make up and don't get dry in the package. Expensive though, hope the price won't go up to make us give up on them.

The only thing that works for me
Size: 50 count (Pack of 1)
I love these face wipes so much. I cannot use soap due to all the problems I have with my skin. It's so finicky.. I have rosacea with painful P&P and also flare ups of adult acne. I take a med to keep my oil production under control, but that means I end up with a few flakey patches on my cheeks. These are the ONLY face wipes that I've found that not only remove almost all (more on that in a moment) of the makeup I'm wearing, but also seem to help keep my redness under control. I've tried Aveeno Ultra-Calming wipes which profess to help with redness and even those are way too harsh for my skin. The Aveeno wipes make my face sting horrible, leave a greasy residue, and have a smell that is not very pleasant. The Simple wipes take off WAY more makeup than those, or any other wipe, I've tried and leave my skin feeling actually clean and calm. The only routine that I've found that keeps my skin looking decent is to use these to remove the majority of my makeup and then follow up with Simple Micellar Water on a cotton pad to remove any further traces. I follow that up with a few spritzes of (rosewater is supposed to help with redness too) and then moisturize with - which doesn't have SPF (which makes my rosacea flare up). It sounds like a lot of steps, but it takes me 3 minutes, tops. I'd just like to add too for those saying that these don't remove waterproof mascara - well, yeah. I would want neither a "gentle" face wipe that was harsh enough to remove waterproof mascara, nor a mascara that was wimpy enough to be removed with a gentle wipe... that would mean it would also come off every time my eyes watered or even just blinked. Just use an oil-free eye makeup remover before using these.

These are great they make you skin feel fresh. They never irritate my face. Always you one before moisturizer.
