Problems solved by technology
In addition, in the case of metering or dissolving the detergent, the powdered detergent is picked up by hand and stirred in water, so that irritation may be felt due to the influence of the ingredients in the detergent.
Further, during washing, due to immersing hands in the washing solution for a long time, the hands feel slippery or irritated under the influence of alkali components or cleaning ingredients. Greasy, so it is accompanied by unpleasant feeling, and there are cases where care with hand cream is necessary

Embodiment
[0133] The following examples illustrate the implementation of the present invention. Examples are for illustration of the present invention, and are not intended to limit the present invention.
[0134] The following compounding components and the components of Tables 1-4 were applied, and the powder cleanser composition shown in Tables 1-4 was prepared by the compaction granulation method. Specifically, after mixing component (b) or component (b') and component (c) with a ribbon mixer, component (a) and component (d) are sprayed and stirred to obtain the target composition . Components other than the above are arbitrarily mixed and blended in the final step. Evaluation was performed by the following method. The results are shown in Tables 1-4.

Abstract
The present invention is a powder cleaning agent composition containing (a) an anionic surfactant, (b) a carboxylic acid whereof the primary acid dissociation constant is between 1 and 5 inclusive, the maximum acid dissociation constant is 7 or lower, and the molecular weight is between 46 and 5,000 inclusive, and (c) one or more species of compounds chosen from among inorganic sulfates and inorganic halogenated compounds, each in a predetermined range. The powder cleaning agent composition has a content of 10% or less by mass in inorganic carbonate whereof the solubility is 0.1 g or greater in 100 g of water at 20°C. The powder cleaning agent composition contains, in a specific mass ratio and serving as (a), a specific alkyl sulfate ester salt and one or more species chosen from among specific polyoxyethylene alkyl sulfate ester salts and specific alkyl benzene sulfonates. The (a) / (b) ratio by mass is between 1 and 40 inclusive. The powder cleaning agent composition has a total content of 4% by mass or less in predetermined protease granulated material and predetermined cellulase granulated material. When the powder cleaning agent composition is diluted 300-fold in water at 20°C, the pH is between 2.5 and 6.5 inclusive.
Description
technical field [0001] The invention relates to a powder detergent composition and a hand-washing method for clothes. Background technique [0002] Since it is considered that the cleaning power is improved by making the pH of the cleaning solution alkaline, the powder detergent composition generally contains an alkali component. [0003] Japanese Patent Application Laid-Open No. 2013-213184 discloses that a powder cleansing composition containing an alkali metal salt of carbonate or an alkali metal bicarbonate as an alkali component exhibits excellent cleaning power against dirt on collars and cuffs during washing of clothes and the like. [0004] In recent years, the popularity of washing machines tends to increase in the Asian region, and hand washing is still widely performed from the viewpoint of cleaning power, economical efficiency, cultural background, washing awareness, and the like. Compared with washing with a washing machine, hand washing is suitable for fine cl...
