In the present specification, the oil absorption capacity of raw materials, base granule groups and the like is a value determined by the method described in the quality evaluation method described later. The powder raw material having an oil absorption capacity of 0.4 mL / g or more is an essentially porous substance having fine pores of 10 μm or less inside the powder, and a surfactant is supported on the pores.

In the present application, the bulk density of the base granule group is the bulk density after removing granules of 2000 μm or more, and the bulk density of the detergent particle group is the bulk density after removing particles of 1180 μm or more.
ベース顆粒群を用いた洗剤粒子群の製造法において、洗剤粒子群の吸油性を示す指標として、下式で定義される嵩密度上昇度を用いることができる。嵩密度上昇度の値が大きいほど、洗剤粒子群の吸油性が高い。本発明において、洗剤粒子群の嵩密度上昇度としては、1.2~1.7が好ましく、1.3~1.6がより好ましい。
嵩密度上昇度=(洗剤粒子群の嵩密度)/(ベース顆粒群の嵩密度) 2. Bulk density increase degree In the manufacturing method of the detergent particle group using the base granule group, the bulk density increase degree defined by the following formula can be used as an index indicating the oil absorption of the detergent particle group. The larger the value of the bulk density increase, the higher the oil absorption of the detergent particle group. In the present invention, the degree of increase in the bulk density of the detergent particle group is preferably 1.2 to 1.7, more preferably 1.3 to 1.6.
Increase in bulk density = (bulk density of detergent particles) / (bulk density of base granules)

Average particle diameter The average particle diameter is measured by the following two methods.
(1) For media with an average particle size of 80 μm or more, use a JIS K 8801 standard sieve (mesh 2000 to 125 μm) for 5 minutes, and then calculate the median diameter from the weight fraction of the sieve mesh size.

The weight of the particles remaining on each sieve and the tray is measured, and the weight ratio (%) of the particles on each sieve is calculated. The average particle size is obtained by accumulating the weight ratio of the particles on the sieve having a small mesh size in order from the saucer, and the total particle size becomes 50%.
尚、本願においてはベース顆粒群の平均粒径は2000μm以上の顆粒を除去した後の平均粒径とし、洗剤粒子群の平均粒径は全粒の平均粒径とする。 In addition, about the thing with an average particle diameter of 125 micrometers or less, it is the same using the 12 steps | paragraphs sieve and saucer of 45 micrometers, 63 micrometers, 90 micrometers, 125 micrometers, 180 micrometers, 250 micrometers, 355 micrometers, 500 micrometers, 710 micrometers, 1000 micrometers, 1400 micrometers, and 2000 micrometers in openings. Measure and calculate the average particle size.
In the present application, the average particle size of the base granule group is the average particle size after removing granules of 2000 μm or more, and the average particle size of the detergent particle group is the average particle size of all the particles.
上記平均粒径の測定と同様の方法により、それぞれの篩及び受け皿上に残留した該粒子の重量を測定し、各篩(目開きDp[μm])上の該粒子の重量割合(累積率R(Dp)[μm])を算出する。そして、各logDpに対するlog(log(100/R(Dp)))をプロットした時の最小2乗近似直線の傾きnを、Rosin-Rammler数とする。 4). Rosin-Rammler number By the same method as the measurement of the average particle diameter, the weight of the particles remaining on each sieve and the saucer was measured, and the weight ratio of the particles on each sieve (opening Dp [μm]) (Cumulative rate R (Dp) [μm]) is calculated. Then, the slope n of the least square approximation line when log (log (100 / R (Dp))) is plotted against each logDp is defined as the Rosin-Rammler number.
水分測定は赤外線水分計法により行う。即ち、試料3gを重量既知の試料皿にはかり採り、赤外線水分計(ケット科学研究所(株)製FD-240)を用いてベース顆粒群については200℃で加熱、又、洗剤粒子群については105℃で加熱し、30秒間重量変化がなくなった時点を乾燥終了とする。そして、乾燥後の重量と乾燥前重量から水分量を算出する。 5.

That is, 3 g of a sample is placed on a sample dish having a known weight, and the base granule group is heated at 200 ° C. using an infrared moisture meter (FD-240 manufactured by Kett Science Laboratory Co., Ltd.). Heating is performed at 105 ° C., and when the weight change disappears for 30 seconds, the drying is finished. Then, the water content is calculated from the weight after drying and the weight before drying.
流動時間は、JIS K 3362により規定された嵩密度測定用のホッパーから、100mLの粉末が流出するのに要する時間とする。流動時間として10秒以下が好ましく、8秒以下がより好ましく、7秒以下が更に好ましい。 6).
