More specifically, the present invention relates to a high bulk density detergent composition that exhibits excellent solubility and detergency even when used under conditions of low mechanical power during washing or even at low water temperatures. It relates to a bulk density detergent composition.

  Washing machines on the market in recent years are responding to consumer needs for “easy to finish washing”, tending to increase capacity (can wash many clothes at once), and wash for a short time during washing time Mode settings are made. Furthermore, a weak agitation mode has been set to address the need to “carefully wash clothes” and appealed to reduce clothing damage. In addition, there is a trend toward saving water, low-temperature washing, and shortening operation time in response to environment / energy and economic efficiency.

  This trend is to reduce the work capacity of the washing machine (mechanical force x time). As a result, the cleaning power is reduced due to the decrease in the dissolution rate of the detergent particles, and the washing of the powder detergent is completed at the end of washing. Undissolved and increased clothing residue of detergent particles.

  As an attempt to improve the solubility, for example, in Patent Document 1, when preparing a clutcher slurry containing zeolite, citrate is added to improve the strength of beads obtained by spray drying, and the beads A detergent comprising a high bulk density detergent particle group having a large average particle diameter and having a high solubility characteristic by applying a surfactant is disclosed.

  Patent Document 2 discloses a detergent composition having filler particles such as sodium citrate and sodium bicarbonate in a base powder having less than 10% by weight of particles less than 150 μm and less than 10% by weight of particles greater than 1700 μm. Has been.

  Patent Document 3 discloses a high-density granular detergent whose solubility is improved by the particle size distribution.

Patent Document 4 discloses a high bulk density granular detergent composition comprising an anionic surfactant, a nonionic surfactant and zeolite, and the content of the nonionic surfactant is 3 to 9% by mass. There is disclosed a high bulk density granular detergent composition characterized in that the zeolite content is 26-35% by mass.
