本発明は粒状洗剤に使用する安定なゼオラィトスラリー
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to stable zeolite slurries for use in granular detergents.
周知の通り、粒状洗剤は現在低リン化乃至は無リン化の
傾向にある。As is well known, granular detergents are currently becoming less phosphorous or less phosphorus-free.
そして衣類用粒状洗剤の低リン化乃至は無リン化を図る
方策として、従来のリン酸塩系ビルダーの代りに水不落
・性のアルミノ珪酸塩（ゼオラィト）を使用することが
提案されている（特開昭５０−１２３８１）。ゼオラィ

乾燥する方法が良好と思われる。As a measure to reduce or eliminate phosphorus in granular laundry detergents, it has been proposed to use water-resistant aluminosilicate (zeolite) instead of conventional phosphate builders. (Japanese Patent Application Laid-Open No. 50-12381). A method for producing granular detergent containing zeolite is to prepare a slurry in which finely powdered zeolite is dispersed in water,
It seems to be best to spray-dry the zeolite slurry and detergent slurry in the same drying tower, or to mix them with the detergent slurry and spray-dry them.

った。However, the zeolite slurry is unstable due to the difference in specific gravity between water and aluminophosphate, and when stored statically, the zeolite will settle and separate, which is not preferable. As a result of intensive research to obtain a zeolite slurry that is stable even during long-term storage, the present inventors have discovered that a stable slurry can be obtained by using a specific water-soluble zeolite slurry as a stabilizing agent. Based on this knowledge, we have completed the invention.
即ち、本発明のゼオラィトスラリーは分散安定剤として

It is characterized by containing at least one kind of.
本発明で使用ゼオラィトは天然及び合成ゼオライトが使

を含有するスラリーに各種の添加剤を加え、記の試験法
によって各スラリーの分散安定性をテストした。As for the particle size of the zeolite, it is preferable that the average particle size is 5 peaks or less and that it does not substantially contain particles with a particle size of 10 peaks or more. The amount of zeolite in the slurry is 15-5% by weight
, preferably 30-45% by weight, and the amount of dispersion stabilizer is 1
~10% by weight, preferably as low as 2-1% by weight are suitable. Example 3 Synthetic zeolite fine powder with fluctuation% (average particle size 0.7 peaks)
Various additives were added to the slurry containing the following, and the dispersion stability of each slurry was tested using the test method described below.
静直分離テスト；一定量のスラリーを円筒状シリンダー
に収め、室温で２日間静遣し、分離状態を調べた。Static and vertical separation test: A certain amount of slurry was placed in a cylindrical cylinder, left to stand still at room temperature for 2 days, and the state of separation was examined.
分離の度合は全体に対する上澄み層の厚さの割合を ％で表示し、分離しなかった試料は◎ で示した。The degree of separation is determined by the ratio of the thickness of the supernatant layer to the total thickness. Displayed in %, samples that were not separated are ◎ It was shown in
