Biobel Oxygen Whitener 1Kg


Sodium percarbonate, better known as washing soda, is a powerful natural stain remover, whitener, disinfectant and deodorizer for clothes.

Added to your machine wash it assists your detergent, or, when used for pre-wash soaking, it naturally gives a more luminous whiteness to your clothes, without using bleach, chlorine or optical brighteners. It is just as effective as a stain remover for heavily soiled coloured garments, as it does not bleach them, but swiftly softens the dirt and enhances the effect of your detergent.

Its impressive 100% natural, deodorizing, antiseptic, disinfectant and bactericide effectiveness (Norma UNE 1040/2006) makes this an essential product for tackling dirty sports clothes, eliminating the odours of pet beds and accessories, as well as disinfecting garments and household surfaces.

It is made exclusively with plant-sourced ingredients, without any ethoxylated or animal sourced ingredients. The ingredients are 100% naturally sourced.

Unperfumed and allergen free.

Natural detergent certified by ECOCERT Greenlife according to the ECOCERT standard, which can be consulted at


To achieve optimum effectiveness for your wash, having used Biobel Oxygen Whitener as a pretreatment we recommend using Biobel Liquid Detergent or Babies and Delicate Fabrics Detergent.

To remove the smell of sweat when machine washing sports clothes, add a couple of spoonfuls of Oxygen Whitener to the Liquid Detergent.

To disinfect and eliminate the odour from pet beds and accessories, add a spoonful of the product along with the detergent.

To whiten cloth nappies use Oxygen Whitener to reinforce the action of the Biobel Babies and Delicate Fabrics detergent. If the nappies are very dirty, use our Oxygen Whitener as a pretreatment. This will make it easier to eliminate stains and the nappies will be left bright white once more.

Diluted to 0.4% it acts as a 100% natural disinfectant and bactericide for garments and household surfaces.

Guidelines for use

Follow the washing instructions provided by the garment manufacturer.

As a stain remover or pre-wash whitener treatment, add one to two tablespoons (15-30g) per litre of hot or warm water, depending on the water hardness. Allow the product to dissolve in the water and then add and fully immerse the garments, leaving them to soak for a couple of hours. For difficult stains apply the product to the stain with a brush. Then wash the garment as normal in the washing machine.

To complement your wash cycle and/or use it as a deodorizer for very dirty clothes, or when washing whites, add detergent to your washing machine as per normal and then add two three table spoons (30-45g) of whitener, depending on water hardness, placing it directly inside the washing machine along with the clothes. For very dirty items, it is recommended to use it on hot wash cycles if possible.

Do not soak or wash metallic garments or items. For special garments and fabrics or delicate dyes, and when washing items for the first time, test the product first somewhere hard to see on the garment. To be as environmentally friendly as possible, always wash a full load, choose low temperature wash cycles and follow the dosage guidelines.

As this is a highly concentrated product, for household disinfection and cleaning, 4ml of the product diluted in a litre of water is sufficient to eliminate any micro-organisms on the surfaces to the washed.


>30% sodium percarbonate. 100% of the ingredients are naturally sourced: pure sodium percarbonate without bleach, chlorine or optical whiteners.
