Respectively (B) composition shown in (A) composition shown in the table 1 and the table 2 is mixed with the use level shown in the table 3, make cleansing composition.The foam viscosity of each compositions that following mensuration obtained.The results are shown in table 3.
(foam viscosity mensuration)
The cleansing composition that is obtained is adjusted the aqueous solution of cleansing composition in the following sequence, then, measure a certain amount of foamy viscosity that is produced.
1) at room temperature, above-mentioned cleansing composition that is obtained and ion exchange water are injected 200 milliliters beaker (IWAKI with the match ratio shown in table 3 and the table 4
TE-32PYREX (registered trade mark)) in, modulates the cleansing composition aqueous solution 50g of 1.0 quality %.
2) at room temperature,, make each composition finely divided in water to same beaker internal radiation ultrasound wave 10 minutes.
3) same beaker be impregnated in 25 ℃ the temperature chamber, use homogenizer [T.K.ROBOMICS プ ラ イ ミ Network ス (strain) (PRIMIX Corporation) system], make it become uniform aqueous solution and produce foam with 6000r/min stirring 5 minutes.
4) foam that uses the scraper of silicones system will be attached to the blender mixing part is collected and above-mentioned 1) in the identical beaker, under 25 ℃, left standstill 30 minutes.
5) at room temperature, the rotor (No.3) of Brookfield viscometer (TOKIMEC INC. system) is inserted in the foam segment, measures 1 minute foam viscosity with the rotation number of 12r/m.
According to the measurement result that is obtained, based on following standard evaluation alveolar substance.The results are shown in table 3.
The evaluation criterion of＜alveolar substance 〉
◎: foam viscosity feels that tactility elasticity is abundant more than 4000mPas, and foamy shape texture is very fine and smooth, is butyrous.
Zero: foam viscosity is more than 2000mPas, and not enough 4000mPas thinks tactility elasticity deficiency.And foamy shape is inhomogeneous, and the foam and the macrofoam of texture exquisiteness mix, and place soon foam becomes macrofoam entirely with regard to converging.
*: the not enough 2000mPas of foam viscosity, feel that tactility is very light.And foamy shape all is big and transparent.Placing the back foam vanishes rapidly.

Embodiment 13～15 and comparative example 7
Use (A) composition shown in table 1 or the table 2 and (B) composition, mix, make cleansing composition with the use level shown in the table 4.Then, to measure 1 with above-mentioned foam viscosity) during the aqueous solution of identical order modulation cleansing composition, add sodium hydrate aqueous solution or aqueous hydrochloric acid solution, be adjusted to the pH value of regulation.To the cleansing composition aqueous solution that obtained with above-mentioned 1)～5) identical method measures foam viscosity, estimates alveolar substance.The results are shown in table 4.

| The valuation of alveolar substance | ◎ | ◎ | ○ | × | |
By the result of above-mentioned table 3 and table 4 as can be known, the foam viscosity height of cleansing composition of the present invention, alveolar substance significantly improve.In addition, the cleansing composition pH value of aqueous solution that is obtained in embodiment shown in the table 3 1～12 and comparative example 1～6 is 6.5.This numerical value mainly depends on (A) composition, and no matter whether (B) composition exists hardly changes.Therefore, can not need to regulate pH value and obtain the non-irritating cleansing composition of skin.On the other hand, by the result of embodiment 13～15 as can be known,, then can improve its alveolar substance if the pH value of cleansing composition within the scope of the invention.
Industrial applicibility
Cleansing composition of the present invention has been owing to improved alveolar substance, shown the low irritant to skin, so, can be applicable to directly contact especially the removers such as facial agent, bath agent, shampoo of skin.
