本発明は耐ケーキング性が改良された高密度の粉粒状非
イオン洗剤組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field] The present invention relates to a dense, particulate nonionic detergent composition with improved caking resistance.
低泡性を要求される洗剤には非イオン界面活性剤が主洗
浄基剤として使われている．しかしながら、非イオン界
面活性剤には粘着性のあるものが多く、これを多量に含
む粉粒状洗剤は一股に耐ケーキング性が良くない。Nonionic surfactants are used as the main cleaning base for detergents that require low foaming properties. However, many nonionic surfactants are sticky, and granular detergents containing large amounts of nonionic surfactants do not have good caking resistance.
近年、洗剤のコンパクト化の要望が高まり、洗剤は高密
度化されつつあるが、高密度化されると耐ケーキング性
はさらに悪くなる傾向にある。In recent years, there has been an increasing demand for compact detergents, and detergents are becoming more dense, but as the density increases, the caking resistance tends to worsen.
このような高密度粉粒状非イオン洗剤の粉末物性を改良
するため、いくつかの研究がなされている。Several studies have been conducted to improve the powder properties of such high-density nonionic detergents.

粉粒状洗剤が得られることが記載されている。For example, JP-A-53-43710 discloses that a free-flowing, high-density granular detergent can be obtained by impregnating spray-dried builder basic beads with a non-ionic surfactant. 62-263299 discloses that a solid detergent obtained by kneading and mixing zeolite, light sodium carbonate, and a nonionic surfactant is crushed to produce a high-density powder that does not exude the nonionic surfactant. It is stated that a granular detergent is obtained.

[Means for Solving the Problems] As a result of intensive research to solve the above problems, the present inventors have found that if heavy sodium carbonate and light sodium carbonate are used in a specific ratio, caking resistance can be improved. The present inventors have discovered that a high-density nonionic detergent composition with improved properties can be obtained, and have completed the present invention. That is, in the present invention, a nonionic surfactant is used as the main cleaning base, and (a) heavy sodium carbonate and (b) light sodium carbonate are used in a (a)/(b) weight ratio of 0.15 to 0.4.
