Sodium Percarbonate Coated
Description
Sodium percarbonate is a free-flowing powder with a common name of solid hydrogen
peroxide, it is an addition compound of sodium carbonate and hydrogen peroxide. Sodium
Percarbonate has an active available oxygen content which is equivalent to 27.5% H2O2. It
breaks down to oxygen, water and sodium carbonate upon decomposition.
Sodium Percarbonate offers many of the same functional benefits as liquid hydrogen peroxide.
It dissolves into water rapidly to release oxygen and provides powerful cleaning, bleaching,
stain removal and deodorizing capabilities. Besides, sodium carbonate decomposed from
sodium percarbonate is able to increase the pH value in washing water to knock down the
activities of calcium ion and magnesium ion, thus intenerates water. Another benefit offered by
sodium carbonate by raising the pH value is to reduce the negative charges of dirt and fibre
resulting in the strengthening repellency between dirt and fibre, which leads to the
improvement of bleaching and stain removing effects.
Compared with chlorine bleach, sodium percarbonate based oxygen bleach boasts following
advantages in laundry formulations:
1. No environmental hazards–it breaks down to oxygen, water and sodium carbonate (soda
ash) in your wash water.
2. Ideal stain removal capability; It is very effective as a laundry presoak for heavily stained
articles.
3. It is used to for deodorizing and disinfecting.
4. Color safe and fabric safe. It brightens colors
5. Does not weaken the strength of fabrics
6. Prevents fabric from becoming yellowed or darkened
7. Effective in a broad range of water temperatures

Applications
Sodium percarbonate has a wide range of applications in various cleaning products and
detergent formulations including heavy duty laundry detergents, all fabric bleaches, wood deck
bleaches, textile bleaches and carpet cleaners. Other applications have been explored in
personal care formulations, denture cleaners, pulp and paper bleaching process, and certain
food bleaching applications. The product also has functions as disinfector for institutional and
home applications, oxygen releasing agent in aquaculture, waste water treatment chemical,
first-aid oxygen generating agent, etc.
