Description

The present invention relates to cleaning compositions, particularly cleaning compositions used for cleaning skin and hair.

Conventionally, cleaning compositions such as shampoos and body shampoos used for cleaning the skin and/or hair mainly contain anionic surfactants with excellent cleaning and foaming properties, amphoteric surfactants, and nonionic surfactants. In addition to various cleaning ingredients such as surfactants, the formulation contains a thickener that gives the formulation an appropriate viscosity, and a conditioning agent that makes it easier to run through with your fingers during rinsing.

Anionic surfactants, which are the main components of cleaning compositions, may not provide satisfactory foaming or foam quality during cleaning, or feel during rinsing or after cleaning, and cleaning compositions that improve these issues have been proposed. (Patent Documents 1 to 5). On the other hand, in Patent Documents 1 to 5, no evaluation has been made regarding improvement in foam sustainability after foaming. Poor foam retention results in poor usability during cleaning, so there is still room for solutions regarding foam sustainability.

(Test Example 1: Foam persistence test)
1 g of the cleaning compositions of Examples 1 and 2, Comparative Examples 1 and 2, and Reference Example 1 and 9 g of purified water were added to a 50 mL screw tube, mixed, and allowed to stand. Thereafter, the screw tube was shaken 15 times, and the time required for the liquid level to rise to 7 mm from the bottom was measured. In the collapse process of bubbles, the liquid inside the bubble film flows downward due to gravity, the liquid is drained to the bottom, and the bubbles coalesce at the top, making the bubble unstable and collapsing. In other words, the longer the bubbles persist, the longer it takes for the liquid level to rise. Therefore, when the time required in Reference Example 1 was twice or more, the foam sustaining effect was rated as ○, and when the time was less than twice the time required in Reference Example 1, the foam sustaining effect was designated as ×. The results of Reference Example 1, Examples 1 and 2, and Comparative Examples 1 and 2 are shown in Table 1.

実施例３～４、比較例３～５、及び参考例１－２について、試験例１と同様の方法で泡持続試験を行った。すなわち、各洗浄用組成物１ｇと精製水９ｇを５０ｍＬスクリュー管に加えて混合し静置し、その後、スクリュー管を１５回振盪し、底から７ｍｍまで液面が上昇するまでの時間を測定した。参考例１－２で要した時間より２倍以上になった場合を泡持続効果が○、参考例１－２で要した時間より２倍未満の場合を泡持続効果が×とした。結果を表２に示す。

For Examples 3 to 4, Comparative Examples 3 to 5, and Reference Example 1-2, a foam duration test was conducted in the same manner as in Test Example 1. That is, 1 g of each cleaning composition and 9 g of purified water were added to a 50 mL screw tube, mixed and allowed to stand, then the screw tube was shaken 15 times, and the time until the liquid level rose to 7 mm from the bottom was measured. . The foam sustaining effect was rated ○ when the time was twice or more than the time required in Reference Example 1-2, and the foam sustaining effect was rated × when the time was less than twice the time required in Reference Example 1-2. The results are shown in Table 2.

As is clear from Tables 1 and 2, the foam sustaining effect was not improved by the addition of Arum extract, peach extract, panthenol, or taurine alone. On the other hand, in Examples 1 to 4, which contained both taurine and at least one member selected from the group consisting of Arum extract, peach extract, and panthenol, the persistence of foam was improved.

According to the present invention, it has become possible to provide a cleaning composition containing sodium coconut oil fatty acid methyltaurate and coconut oil fatty acid N-methylethanolamide, which has improved foam sustainability.
