Polysulfide-containing white liquor is added intermixed with the first liquor charged to the digester, or as a separate charge before the impregnation liquor is introduced.

Separately from extraction of ex-digestion liquor, liquor containing the washing medium is removed and passed to concentration and combustion steps which optionally are arranged after admixture to black liquor.

According to the method foaming of the black liquor is reduced by adding stabilized colloidal neutral substances to the black liquor.

These coated sodium percarbonate particles used as detergent components lead to an improved washing power of the detergent and exhibit high storage stability in detergent preparations.

The present invention relates to a process for treating white liquor in pulp and paper mills, the process comprising oxidation of white liquor.

Therefore, it is possible to facilely remove a detergent remaining in the laundry and prevent damage of the laundry due to increase in the number of rinsing processes.

White liquor (14) is treated with oxygen (13) so as to oxidize all of the sulfur forms within the white liquor to sulfates.

The dispenser (1) is used, for example, for mounting on a washing powder packing for optimising dosing of washing powder.

Portions of the liquor flow from a liquor at the bottom of the liquor container (1) through the inlet opening (14') into the cavity (13') of the driver (11').

Use hypoallergenic laundry detergent and do not add fabric softener to the wash water.

The drain device, particularly the hose of the drain device, comprises a suds collecting unit that is designed to prevent backflow of the suds out of the drain device into the collar.

This has increased the efficiency of doing laundry.
