Embodiment 1、3～27、 and comparative example 2、4～7

[0274]

[0275] Into a 50mL beaker, add (B) component of the type and mixing amount (mass %) shown in Tables 1 to 3, and (D) component (D) in an amount (%) 8 times the amount (%) of (B) component, and use a magnetic stirrer to (MITAMURA RIKEN KOGYO INC.), the amount of the solution is about 1cm up from the bottom of the beaker, stir it for 20 minutes with a stirring bar with a length of 25mm and a diameter of 8mm to dissolve it, and then add the types and mixing amounts shown in Tables 1 to 3 (mass %) (C)component is further stirred and pre-mixed to obtain a pre-mix.

[0276] Separately, in a 500 mL beaker, 20.0% of (D) component, 7.0% of alcohol as an optional component, 0.3% of citric acid, 1.0% of MEA, the types and mixing amounts (mass %) shown in Tables 1 to 3 ( A) Ingredients, stir to dissolve these ingredients.

[0277] Next, the pH of the solution at 25° C. was adjusted to 7 with a pH meter (manufactured by Toa Daike Corporation: product name HM-30G) using sodium hy...

[0280]

[0281] Into a 500mL beaker, add 20.0% of (D) component, 7.0% of alcohol as an optional component, 0.3% of citric acid, 1.0% of MEA, and (A) component of the type and mixing amount (mass %) shown in Tables 1 and 3 And (B) component, stir, and these components are dissolved. .

[0282]Next, with a pH meter (product name HM-30G, manufactured by Toa Daikeke Co., Ltd.), sodium hydroxide and hydrochloric acid were used as pH regulators to adjust the pH of the solution to 7 at 25°C. Then, add the (C) component of the type and mixing amount (mass %) shown in Tables 1 and 3, and stir further, by adjusting the mixing amount of the (D) component, the total amount of the liquid cleaning agent composition of the final product is 100%, thereby obtaining a liquid detergent composition.

[0283] The obtained liquid cleaning composition was evaluated for enzyme activity, storage stability, and cleaning ability. The results are shown in Tables 1-3.

Abstract

Disclosed are: a liquid detergent composition which does not undergo the deterioration in the activity of an enzyme contained therein and can maintain the storage stability of the enzyme at a good level even when a surfactant is contained therein at a high concentration; and a process for producing the liquid detergent composition. The liquid detergent composition is characterized by comprising the following components (A) to (D): (A) a surfactant (wherein a nonionic surfactant makes up 60 mass% or more of the component (A)); (B) a homopolyamino acid and / or a salt thereof; (C) an enzyme; and (D) water.

Description

technical field [0001] The present invention relates to liquid cleaning compositions and methods for their manufacture. [0002] this application claims priority based on Japanese Patent Application No. 2009-252159 for which it applied to Japan on November 2, 2009, The content is used here. Background technique [0003] There are powder-type and liquid-type laundry detergents used in household laundry. [0004] Powder cleaning agent is advantageous in terms of stably mixing functional materials that are unstable in water or functional materials that react in water because the cleaning agent contains less water, and it has various characteristics that make full use of this characteristic. is being developed. [0005] Among the functional raw materials used in laundry detergents, enzymes are one of the important functional raw materials, especially under the harsh laundry conditions in Japan (low temperature, low concentration, short washing, etc.), they can still exert high...
