In America we have Borax as laundry booster.
It isn’t the same as Boric acid.
Boric acid is poisonous if taken internally or inhaled in large
quantities. However, it is generally considered to be not much more
toxic than table salt.
It is used as an antiseptic, (eye wash) major cause of poisoning
when it is unlabeled after being mixed with water and placed in the
refrigerator for use as eye wash.
It is also used as a fire retardant, and insecticide(major component
of the assorted roach proof powders and the ant traps) in addition to
a fluxing agent in soldering, welding and brazing.
If you can’t find Boric acid in cones or powder at jewelry supply
houses. You should be able to find it at most pharmacist shop or
better drug stores.
Be warned it is a lot more expensive than at the supply house as it
is medical grade but in the middle of the night on a weekend it will
work in water or alcohol. For fluxing.
Boric acid is the top most expensive use less
Borax the mineral, is referred to as Anhydrous borax, as it pulls
moisture out of the air during storage.
Dehybor is short for dehydrated borax that is fused so it can’t
absorb water in storage. All the water is removed is a glassy
material that is used in enameling and glass work.
You would use about 1/2 the amount of Dehybor as the borax.
Boraxo works because the sodium soap that is in it doesn’t impede
the fluxing state.It can have 10% to 30% sodium soap as a wetting
Borateem is a laundry detergent and has way to much other
ingredients to work even in a pinch.
BORIC ACID contains 56.3% B2O3 Boric Oxide
BORAX contains 36.52% Boric Oxide
Borax is a mineral not the laundry detergent booster. Boraxo is the
booster or hand soap depending on the labeling.
