General
- Sodium percarbonate
is a white crystalline water-soluble chemical compound of sodium
carbonate and hydrogen peroxide. It is an oxidizing agent and ingredient
in a number of home and laundry cleaning products.
- Sodium percarbonate
is a metastable substance and the bond between the peroxygen atoms can
be broken giving rise to a decomposition producing sodium carbonate,
steam or water, oxygen and heat
Process
- Sodium percarbonate
obtained by the reaction of sodium carbonate solution with 40 – 70 %
hydrogen peroxide solution is currently manufactured in the EU using the
wet crystallisation process and by the dry fluidised-bed process.
- Sodium percarbonate
is manufactured by the chemical reaction of sodium carbonate and
hydrogen peroxide and is mainly used as a bleaching agent in laundry
detergent powders, stain removal and food processing.
Applications
- Sodium percrabonate has
a wide range of applications in various solid detergent products, cleaning
agents and all fabric bleaches. We may also find its usages in oxygen
release compositions, personal care formulations, disinfectants, food
bleaches, pulp and paper bleaches and textile bleaches, etc.
- Sodium percarbonate is
effective as a disinfectant on both bacteria and virus. It’s an excellent
ingredient in personal care and home care formulations for hygiene.
Market
- The most hydrogen
peroxide companies began increasing their capacity as a result of the
double digit demand growth then being experienced and the speculation
would favor the use of total chlorine–free (TCF) bleaching for bleached
wood pulp production. In three years time, hydrogen peroxide capacity in
the U.S. increased by 40 percent.
- Demand for hydrogen
peroxide in the US is forecast to increase 3.6 percent annually to more
than one billion pounds in 2006. Demand for hydrogen peroxide has grown
rapidly over the last decade, primarily due to the replacement of
chlorine as the primarily bleach used by the pulp and paper industry.
Report
- Sodium percarbonate
is an inorganic, water soluble solid of relatively low molecular weight.
The water solubility of sodium percarbonate is 140 g/l at 20 ºC. Sodium
percarbonate rapidly dissolves in water and dissociates into sodium
ions, carbonate ions and hydrogen peroxide.
- The chronic toxicity
of sodium percarbonate can be predicted from the chronic toxicity of
hydrogen peroxide. A chronic toxicity study with invertebrates and
hydrogen peroxide revealed a NOEC of 2 mg/l.
