Definitions
- the object of this invention is a process for the preparation of stable oxygen-yielding washing powders, utilizing percarbonate salts such as the alkali metal percarbonates. It has been found that stable compositions are obtained when the moisture content is restricted in accordance with the following disclosure.
- Washing powders are ordinarily powdery mixtures which contain besides soap powders also additional materials such as soda, water glass and the like.
- perborates especially sodium perborate
- these salts when mixed with soap and the other usual ingredients of washing powders, such as soda, water glass and the like, were the most stable.
- mixtures with a moisture content of about 25% are much more stable, and that mixtures with a moisture content 01' 10% or less, preferably 5-7%, have such good stability that they are in no way inferior to the detergents prepared with alkali metal perborates and remain practically unchanged after several months storage. If desired, the water can be extracted to such an extent that practically dry substances are obtained.
- the novel stable oxygen-yielding washing powders containing percarbonate with which our invention is concerned may be prepared by adding an alkeiim tel-nereerbo such a sodium percarbonate, to a detergent mixture comprising soap and sodium garb onate.
- the detergent r'n ixtuie' may contain, in addition to the soap and soda, other substances which are usually present in washing powders such as water glass (sodium silicate).
- the resulting mixture is dehy drated so that its moisture content falls within tl'ie'iange 5 to This range represents the per cent moisture content by weight and is based upon the weight of the ingredients comprising the complete oxygen-yielding washing powder.
- antioxidants such as magnesium silicate, and the like.
- soap substitutes such as fatty alcohol sulfonates and the like, may be used.
- a stable alkaline oxygen-yielding washing powder which comprises an alkali metal percarbonate, sodium carbonate, and soap, the moisture content of said washing powder falling within the limits 5 to 7% by weight, based on the weight of said washing powder.
- a stable alkaline oxygen-yielding washing powder which comprises an alkali metal percarbonate, sodium carbonate, soap, and water glass, the moisture content of said washing powder falling within the limits 5 to 7% by weight, based on the weight of said washing powder.
