Problems solved by technology

[0011] This granular detergent composition and its production method can not only solve the problems of solubility, hygroscopic caking and sticking equipment at the same time, but also can obtain a variety of granular detergent compositions, and solve the problem of the combination of granular compositions therein. For the production of traditional detergent compositions that exist in one particle, the production efficiency decreases when the product type is changed

[0202] Composition (A-1) in Table 1 was made of non-ionic surfactant-free components, 4.0% equivalent of type A zeolite for addition during kneading, 5.2% equivalent of type A zeolite for grinding aid Zeolite, 1.5% equivalent of zeolite type A for surface covering, and pigment and fragrance were dissolved or dispersed in water to prepare a slurry with 40% water. The resulting slurry was then spray-dried using a counter-current spray-drying tower at a hot air temperature of 300°C to obtain spray-dried granules with 4% water. This spray-dried granule, 4.0% equivalent of A-type zeolite, nonionic surfactant, and water were loaded into a continuous kneader (KRC-S4 type, product of Kurimoto Ltd.) at a temperature of 60° C. by 120 kg The kneading capacity of / h kneads the resulting mixture to obtain an indeterminate solid detergent. ...

[0218] (A-3) Preparation of detergent particles comprising anionic surfactant as main surfactant

[0219] (A-3-1) Dry neutralization with a fluidized bed

[0220] The powder raw material (not including the coating agent) comprising the potassium carbonate and sodium carbonate ground products in the amounts shown in Table 1 (A-3) was charged into a fluidized bed (Glatt-POWREX, model FD-WRT-20, Powrex Corp. In the product of ), this amount of powder raw material results in a powder layer thickness of 200 mm during standing. Then the air at 20°C flows into the fluidized bed to fluidize the powder, and then the α-SF-H is shot towards the powder layer and sprayed on the powder from above. The granulation is performed while ensuring the fluidized state by adjusting the air velocity in the fluidized bed within the range of 0.2 to 2.0 m / s.

[0221]The α-SF-H was sprayed at 60°C, and a two-phase hollow cone nozzle with a spray angle of 70° was used as the nozzle for spraying. The sp...

Abstract

A granular detergent composition comprising (A) an anionic surface comprising Detergent particles with active agent as main surfactant, (B) detergent particles comprising nonionic surfactant as main surfactant, and (C) detergent particles comprising builder as main component with surfactant content less than 15% (by weight) of particles.

Description

technical field [0001] The present invention relates to a granular detergent composition excellent in solubility, resistance to moisture absorption and caking, resistance to sticking equipment, and production efficiency when product type is changed, and a production method thereof. Background technique [0002] Traditionally, granular detergents have been blended with anionic surfactants, nonionic surfactants, and builder components, etc., generally contained within a single detergent particle. Much research has been done on granular detergent compositions. However, the production of different types of detergent particles in the same equipment still has problems such as a decrease in production efficiency when the product type changes, including cleaning the inside of the production equipment. [0003] On the other hand, it has also been attempted to load components such as a builder in particles containing a surfactant and other particles, respectively. For example, reduc...
