Description

[[TECHNICAL FIELD]]

[0001] The present invention relates to a detergent composition. [[BACKGROUND ART]]

[0002] Conventionally, anionic surfactants have been used as the main detergent component in detergent compositions. Among them, alkyl sulfate esters such as sodium lauryl sulfate and alkyl ether sulfate esters such as sodium laureth sulfate are most commonly used from the viewpoints of detergency and foaming properties. However, although these components are excellent in detergency and foaming performance, they have the disadvantage that they easily cause skin irritation, and have the problem that skin becomes tight after use due to their excellent degreasing effect.

[0003] In order to solve these various problems, detergent compositions have been developed that use acyl amino acid salts among anionic surfactants to alleviate skin irritation and thus exhibit a mild feeling during use. However, acyl amino acid salts have problems such as poor "foam volume", "fine foam texture" and "foam retention (foam persistence)" formed during use, and it has not been possible to obtain a detergent composition that is sufficiently satisfactory in terms of foam quality and feeling of use.

[0004] Therefore, as an attempt to improve the volume and fineness of foam during use, a detergent composition containing an acyl amino acid salt, a solid or semi-solid hydrocarbon oil, and hydroxypropyl starch phosphate has been proposed (see, for example, Patent Document 1). Although these attempts can improve the volume and fineness of foam during use to a certain extent, the foam retention is still poor, and the results have not been fully satisfactory.

[0005] On the other hand, as an attempt to improve the fineness and retention of foam during use, detergent compositions containing a crosslinked product formed by crosslinking acyl-modified starches and an amino acid-based surfactant and / or fatty acid soap have also been proposed (see, for example, Patent Document 2). However, while these attempts can improve the fineness and retention of foam during use to some extent, the amount of foam produced during use is small, and the foaming power is not entirely satisfactory.

[Examples]

[0070] The present invention will be described in more detail below based on examples, but the present invention is not limited to these examples. Unless otherwise specified, the amounts of each ingredient are expressed in "mass%".

[0071] (Sample preparation 1) According to the compositions listed in Tables 1 and 2, the detergent compositions of Examples 1-7 and Comparative Examples 1-9 were prepared by conventional methods and subjected to the following evaluation. The results are shown in Tables 1 and 2. Note that all amounts in the tables are calculated on a pure content basis.

[0072] (Test Example 1: Evaluation of the condition during preparation) The condition of the product immediately after preparation was visually observed and evaluated according to the following evaluation criteria.

[0073] <Criteria for evaluating the condition> ○ (Good): Exhibits a uniform, semi-solid consistency. △ (Insufficient): Does not exhibit a uniform semi-solid state, and clear liquid synergy is observed on the surface. × (Poor): Separation is observed.

[0074] Each sample that received a "○ (good)" result in the evaluation of Test Example 1 above was subjected to the following tests.

[0075] (Test Example 2: Evaluation of User Experience) In each example and comparative example, 0.5 g of the cleansing composition was dispensed into the palm of the hand, the fingertips of one hand were wet, the mixture was lathered on the palm, and then applied to the face for a usage test. Visual evaluations were conducted on the "amount of foam," "fineness of foam," and "foam retention" immediately before application to the face. Sensory evaluations were also conducted on the "lack of tightness in the skin after towel drying," and scores were assigned according to the following 1-5 point scale. The evaluations were conducted by five expert evaluators, and the final result was determined by a comprehensive assessment of each evaluator's evaluation.

[0076] The evaluation of "amount of foam" was based on the amount of foam produced, with higher scores given for larger quantities. The evaluation of "fineness of foam" was based on the fineness of the foam produced, with higher scores given for finer foam texture. The evaluation of "longevity of foam" was based on the persistence of the foam produced, with higher scores given for longer-lasting foam. The evaluation of "lack of tightness in the skin after towel drying" was based on the absence of tightness in the skin after towel drying, with higher scores given for less tightness in the skin after towel drying.

[0077] The evaluation was conducted according to the following five-level evaluation criteria. The results were calculated based on the average score of the expert evaluation panel, and a judgment was made according to the following criteria.

[0078] <Evaluation Criteria> 5 points: Very good 4 points: Good 3 points: normal 2 points: Defective 1 point: Very poor

[0079] <Judgment criteria> ◎: Average 4.0 points or more ○: Average score of 3.0 or higher but less than 4.0 △: Average score between 2.0 and 3.0 ×: Average score below 2.0

[0080] [Table 1]

[0081] [Table 2]

[0082] As is clear from Table 1, the cleansing compositions of Examples 1 to 7, which satisfy the requirements of the present invention, can be prepared as stable compositions and exhibit significantly superior effects in terms of foam quality, such as the "quantity," "fineness," and "longevity" of the foam formed during use. Furthermore, because the cleansing compositions of the present invention allow for treatment with high-quality foam, a pleasant feeling is obtained on the skin after towel drying, without any feeling of tightness.

[0083] On the other hand, comparative detergent compositions that did not satisfy the structure of the present invention, as well as comparative detergent compositions in which other components were substituted, did not yield sufficiently satisfactory results. As is clear from these results, the detergent composition of the present invention can be said to solve the problems related to foam quality, such as the amount of foam, the fineness of the foam, and the foam's retention, that conventional detergent compositions have faced.
