2. Description of the Related Art In recent years, there has been a demand for a detergent composition having low irritation such as "friendly to skin and hair" due to an increase in consumers' awareness of safety such as rough skin and damage to hair. Attempts have been made to use hypoallergenic surfactants as such detergent compositions, and such surfactants include acylamino acid-type anionic surfactants.

Using an aqueous solution adjusted to 5% by weight, a closed patch test was performed on the inner side of the upper arm for 24 hours, and evaluated by the naked eye. A score of 0 indicates no change on the skin, 1 score indicates a slight erythema on the skin, and 2 scores indicate a clear erythema or edema on the skin.
The average of the names was determined and evaluated in the following three stages.

Low skin irritation (average value less than 0.5 point) Moderate skin irritation (average value of 0.5 or more and less than 1.0 point) Strong skin irritation (average value of 1.0 point or more). (2) Foaming property An aqueous solution having a sample concentration of 1% was prepared, and the foam height was measured by the Ross-Miles method at 25 ° C. immediately after the sample was introduced and after 5 minutes.
A foam having a foam height of 150 mm or more immediately after the introduction of the sample and a foam sustainability of 90% or more determined by the following equation was evaluated as a good foaming detergent. Persistence of foam = [(foam height after 5 minutes) / (foam height immediately after sample introduction)] × 100

(3) Creamy Property of Foam The creamy property of the foam was evaluated by observing the foam when 5 ml of the composition was foamed on a bath sponge with 20 women as panelists. The average value of 20 people was calculated assuming that the foam was fine and creamy, 2 points, the foam was slightly coarse, 1 point, and the foam was coarse, 0 point. Those having a score of 1.5 or more were evaluated as having good foam creaminess.

(4) A feeling of sliminess after rinsing A woman of 20 persons was used as a paneler, and her fingers and forearms were washed using about 5 ml of a composition taken on a bath sponge.
After rinsing three times while flowing with 1 liter of hot water of ° C., the sliminess was evaluated. 4 points when feeling that there is no slimy feeling, 3 points when feeling that there is almost no slimming feeling
The average value of 20 people was calculated as two points when the user felt that the skin was slightly slimy and one point when the skinny slime was persistent. The agent was evaluated.

(5) Refreshing feeling after rinsing The fingers and forearm were washed with 20 women as panelists, and 5 ml of the composition taken on a bath sponge.
The freshness after rinsing three times while flowing with 1 liter of hot water at ℃ was evaluated. 4 points if you feel refreshed, 3 points if you feel slightly refreshed
20 points, 2 points if you feel that there is almost no refreshing feeling, and 1 point if you feel that there is no refreshing feeling.
The average value of the names was determined, and those having an average value of 3.0 or more were evaluated as cleaning agents having a refreshing feeling after washing.

(6) Stability over time The sample was stored at -5 ° C., 25 ° C., and 45 ° C. for one month, and its appearance was observed. 〇: Good stability (transparent or slightly turbid state, no change in appearance) △: Slightly poor stability (slightly turbid or colored) ×: Poor stability (precipitation is recognized or solidified, coloring is remarkable) )
