Description
【発明の詳細な説明】 産業上のや 本発明は、高嵩密度洗剤組成物の製造方法に関する。[Detailed description of the invention] industrial TECHNICAL FIELD The present invention relates to a method for manufacturing high bulk density detergent compositions.
丈朱立反援
従来の衣料用洗剤は、組成物中に洗浄性能にはほとんど
寄与しない増量剤(通常は芒硝が用いられる)を添加し
、かつこれを噴霧乾燥により嵩密度0.3 g /cc
程度のビーズ状中空粒子として製造していた。Conventional laundry detergents have a bulk density of 0.3 g / cc
It was produced as bead-like hollow particles of about 100 ml.
しかし、このような洗剤は比重が軽く活性剤濃度も低い
ため、輸送コストがかさむ上、保管・陳列にもかなりの
スペースが必要であり、さらに一般家庭においても置き
場所に困ったり、計量しにくかった。そこで最近では、
少ない洗剤使用量で洗浄が可能な高嵩密度粒状洗剤の製
造方法が提案されており(特開昭60−96698号公
報)、また、上市されている。However, such detergents have a low specific gravity and a low active agent concentration, which increases transportation costs and requires a considerable amount of space for storage and display.Furthermore, even in ordinary households, it is difficult to find a place to store them and it is difficult to measure them. Ta. So recently,
A method for producing a high bulk density granular detergent that can be cleaned with a small amount of detergent has been proposed (Japanese Patent Laid-Open No. 60-96698), and is also commercially available.
しかしながら、高嵩密度洗剤は、洗剤粒子の内部まで組

ントロールが困難であるという問題があった。すでに上
市されている高嵩密度洗剤のBDは、0.76−0.8
0g/ccであり、これに伴ない容器の大きさ、計量ス
プーン容量は決められている。したがって、B Do、
80g/cc以上の高嵩密度洗剤を製造して同一の容器
、計量スプーンを使用した場合、容器のヘッドスペース
が大きくなり、また、1回当りの使用量が必要以上に増
加するという問題が生じる。この為、高嵩密度洗剤製造
に当り、BDをコントロールする必要がある。However, high bulk density detergents have poor solubility because the composition is packed deep inside the detergent particles, and the bulk density (BD) of the detergent is almost determined by the composition, making it difficult to control. There was a problem that. The BD of high bulk density detergents already on the market is 0.76-0.8.
0g/cc, and the size of the container and the capacity of the measuring spoon are determined accordingly. Therefore, B Do,
If a high bulk density detergent of 80 g/cc or more is manufactured and the same container and measuring spoon are used, the problem arises that the head space of the container becomes large and the amount used per use increases more than necessary. . For this reason, it is necessary to control BD when producing high bulk density detergents.

。As alkali builders, carbonates, silicates, borates, sulfites, etc. can be added to the detergent slurry in an amount of 0 to 30% by weight in the spray-dried detergent particles. If this amount exceeds 30% by weight, the pH of the detergent will become too high, which is not preferable. Furthermore, when blending an α-sulfo fatty acid ester salt as an anionic surfactant in a detergent slurry, the ester bond of this surfactant is cut by an alkaline agent and the α-sulfo fatty acid base decomposes. It is desirable not to include an alkali builder in the detergent slurry. In this case, the alkali builder required for the final detergent composition is supplied from high bulk detergent particles.

On the other hand, if the water content is less than 2% by weight, the drying energy required increases, and the thermal stability during spraying also deteriorates, causing problems such as scorching.

As described in Publication No. 7, detergent raw materials such as anionic surfactants are kneaded and mixed in a kneader, crushed and granulated in a crusher such as a cutter mill type, and then water-insoluble fine powder is mixed. It can be obtained by Alternatively, high bulk density detergent particles can also be produced by spray-drying some or all of the detergent particle components in advance, and kneading and mixing this spray-dried product with the remaining detergent particle components. Furthermore, it can also be obtained by other granulation methods such as stirring granulation.
