Frequently Asked Questions
What is sodium percarbonate?
What is sodium percarbonate?
Sodium percarbonate, also known as percarbonate of soda or oxygen bleach, is a powder that breaks down in water into oxygen, water and soda ash. The released active oxygen breaks down stains and brightens whites without chlorine, which is why it is often called green bleach. VAXEN supplies it as a coated powder in 1500g and 3000g resealable bags.
How do you use sodium percarbonate in laundry?
How do you use sodium percarbonate in laundry?
Add 1 to 2 tablespoons to the drum alongside your regular detergent. For tough stains, make a paste with warm water and apply before washing, or pre-soak: mix with warm water and leave the item for 30 to 60 minutes before a normal wash. Always test on an inconspicuous area first, and follow the garment care label.
What temperature does oxygen bleach work at?
What temperature does oxygen bleach work at?
Sodium percarbonate releases active oxygen once dissolved, and temperature drives the speed of that release. Below about 40°C the release is slow, so for laundry it performs best at 40°C and above, with 50 to 60°C ideal for whites and heavily soiled loads. Cooler water still works, just more slowly: allow longer soak times, and pre-dissolve the powder in warm water first.
Is oxygen bleach safe for coloured clothes?
Is oxygen bleach safe for coloured clothes?
VAXEN Sodium Percarbonate is gentler than chlorine bleach on fabrics and is safe for most whites and colour-fast items. It is not suitable for wool, silk, aluminium or leather. Always test on an inconspicuous area before full use, and check the garment care label.
What is the difference between sodium percarbonate and bicarbonate of soda?
What is the difference between sodium percarbonate and bicarbonate of soda?
They work differently. Bicarbonate of soda is a mild alkali used for gentle cleaning and odour absorption. Sodium percarbonate releases active oxygen when it meets water, which actively breaks down stains and brightens whites. For stain removal and whitening, percarbonate does the heavy lifting; bicarbonate is the milder general-purpose powder.
Why is sodium percarbonate called green bleach?
Why is sodium percarbonate called green bleach?
Because it whitens and lifts stains using active oxygen instead of chlorine, and it breaks down in water into oxygen, water and soda ash. There is no chlorine residue left behind. In the UK the names green bleach, oxygen bleach and percarbonate of soda all refer to the same active ingredient: sodium percarbonate.
