About our boric acid

Do you have an MSDS?

Yes, we do.

How fine is your boric acid powder?

Our boric acid is mostly a fine powder. It is not coarse like sugar or bath flakes. There are some less fine pieces dotted throughout but there are very few and they can be easily sieved out.

What’s the pH of your boric acid?

The pH of our boric acid is 5.2.

What’s the purity of your boric acid?

The purity of our boric acid is 99.5%. This is a “technical grade” and is suitable for general household use. You can get a higher purity but for the uses we recommend, it’s not really necessary. It is also extremely expensive.

Storing boric acid

How do I store the boric acid once it arrives?

All our boric acid products are packaged in self-standing, resealable, commercial-grade (HDPE) containers. It will keep for years like this and you can store it anywhere and any way you’d like. Just remember to keep it out of reach of children.

There’s a safety seal at the bottom of the lid to provide you with extra assurance of its quality. Once opened be sure to screw the lid on tight as an air-tight seal prolongs the life of the boric acid. Screwing it on tight also keeps the contents safe if you knock the jar over.

You do not need a separate container. Our product is an all-in-one solution.

Where should I store my boric acid?

I keep mine on the top shelf of my laundry cupboard, just next to my washing powder. That way I know my children cannot reach it, while still making it easily accessible for me.
