Embodiment 1

[0146] The base particles used in Examples 1-1 to 1-8 were produced by the following procedures.

[0147] Add 460kg of water into the 1m with stirring impeller 3 In the mixing tank, after the water temperature reaches 55°C, add 120kg of sodium sulfate, 140kg of sodium carbonate, and 5kg of sodium sulfite. After stirring for 10 minutes, 170 kg of a 40% by weight aqueous sodium polyacrylate solution were added. After stirring for 10 minutes, add 40kg of sodium chloride and 140kg of zeolite, and stir for 30 minutes to obtain a final temperature of 58°C.

[0148] The slurry at 25kg / cm 2 The spray pressure is sprayed from the pressure spray nozzle installed near the top of the spray drying tower. The high-temperature gas supplied to the spray drying tower was supplied from the lower part of the tower at a temperature of 225°C, and was discharged from the top of the tower at 105°C. The moisture in the base granules was 1.6%.

[0149] The physical properties of the obtained base...

Embodiment 1-1

[0160]Put 100 parts by weight of the basic particle group preheated to 50°C and the powder raw materials shown in Table 2 into the Ldige mixer (manufactured by MATSUBO CORPORATION, capacity 20L, equipped with a jacket), and start rotating the main shaft (rotation of the main shaft Speed: 80r / min, Froude number of stirring impeller: 1.07). And, without rotating a chopper (equipped with a crushing impeller), warm water at 80° C. was made to flow in the jacket at 10 L / min. After performing stirring by spindle rotation for 1 minute, 44 parts by weight of a 60° C. surfactant composition was introduced over 2 minutes, followed by mixing for 6 minutes. Pause the rotation, drop into 5.3 parts by weight of crystalline silicate shown in Table 2 in the mixing device, rotate the main shaft (rotating speed: 150r / min, the Froude number of the stirring impeller: 3.8) and the shredder (shredder) Rotation speed: 3600r / min, Froude number of crushing impeller: 1010) for 15 seconds. After 15 s...

Embodiment 1-2

[0177] With the compositions shown in Table 2, detergent particle groups were obtained in the same manner as in Example 1-1. Table 2 shows the physical properties of the obtained detergent particle group.

[0178] Also, the alkyl chain length of the (a) component in the surfactant composition used in Example 1-2 was 14. Its composition and viscosity are shown in Table 1.

Abstract

A process for the production of uni-core detergent particles which can dispense with the drying step for dehydration after granulation and which makes it possible to produce in high yield uni-core detergent particles containing an anionic surfactant which are little irritant to the skin and exhibit good biodegradability, reduced particle growth, and a sharp particle size distribution.

Description

technical field [0001] The present invention relates to a method for producing a mononuclear detergent particle group containing a compound represented by any one of formulas (1) to (3) as an anionic surfactant. [0002] R-O-SO 3 M (1) [0003] (wherein, R represents an alkyl or alkenyl group with 10 to 18 carbon atoms, and M represents an alkali metal atom or an amine); [0004] R-O(CH 2 CH 2 O) n -SO 3 M (2) [0005] (wherein, R represents an alkyl or alkenyl group with 10 to 18 carbon atoms, the average added mole number n represents 0.1 to 3.0, and M represents an alkali metal atom, ammonium or organic amine); [0006] R-CH-COOA (3) [0007] | [0008] SO 3 m [0009] (In the formula, R represents an alkyl or alkenyl group with 4 to 22 carbon atoms, M represents an alkali metal atom, an alkaline earth metal atom, an alkanolamine or ammonium, A represents an alkyl group with a carbon number of 1 to 4, H or M). Background technique [0010] One of the meth...
