【発明の属する技術分野】
本発明は洗浄剤組成物に関し、皮膚等に対する刺激が少なく、低温安定性、起泡性に優れ、かつ使用感が良好な洗浄剤組成物に関する。
【0002】
【従来の技術】
リン酸エステル系界面活性剤は、石鹸、アルキルエーテルサルフェート、アルキルサルフェート等に比べて皮膚や毛髪に対する刺激が低く、皮膚洗浄剤の成分として広く応用されている。またその特徴ゆえに、広範囲の他のアニオン界面活性剤や非イオン性界面活性剤との混合系などに応用されている。
ところで、一般に、リン酸エステル系界面活性剤は、モノエステルとジエステルの混合物として得られ、アルキルリン酸エステルには、水溶性が悪く起泡力も劣るジアルキルリン酸が混在している。そして、これを洗浄剤主成分として単独で用いたのでは、一般に起泡力、低温安定性等に問題が有るため、更に助剤として界面活性剤を配合する方法が提案されている。
助剤として、特定構造のヒドロキシスルホベタインを用いる方法(例えば、特許文献1参照。)は、起泡力増強、低温安定性改善の点で比較的優れた方法であるが、起泡力、使用感の両方を同時に満足するものではなかった。
助剤として、アルキルサッカライド系界面活性剤を用いる方法(例えば、特許文献2参照。)は、洗浄力、起泡力に優れ、低刺激性であるが、低温安定性と使用感の両方を同時に満足するものではなかった。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a detergent composition, which relates to a detergent composition which is less irritating to the skin and the like, has excellent low-temperature stability and foaming properties, and has a good feeling in use.
[0002]
[Prior art]
Phosphate ester surfactants are less irritating to the skin and hair than soaps, alkyl ether sulfates, alkyl sulfates and the like, and are widely applied as components of skin cleansing agents. Due to its characteristics, it is applied to a wide range of mixed systems with other anionic surfactants and nonionic surfactants.
By the way, in general, a phosphate ester-based surfactant is obtained as a mixture of a monoester and a diester, and the alkylphosphate ester contains a mixture of dialkylphosphoric acid having poor water solubility and poor foaming power. When this is used alone as the main component of the detergent, there is generally a problem in foaming power, low-temperature stability, and the like. Therefore, a method of further adding a surfactant as an auxiliary agent has been proposed.
The method using hydroxysulfobetaine having a specific structure as an auxiliary agent (for example, see Patent Document 1) is a relatively excellent method in terms of enhancing foaming power and improving low-temperature stability. I did not satisfy both feelings at the same time.
A method using an alkyl saccharide-based surfactant as an auxiliary agent (for example, see Patent Document 2) is excellent in detergency and foaming power and is low-irritating, but simultaneously has both low-temperature stability and usability. I was not satisfied.

When the components (A), (B) and (C) are mixed, their order does not matter and they may be simultaneous. Since an increase in viscosity is observed when the component (A) is blended, it is preferable to heat and stir at 40 to 80 ° C.
[0025]
The weight ratio of the alkyl phosphate monoester (a 1 ) to the alkyl phosphate diester (a 2 ) in the component (A) is (a 1 ) / (a 2 ) = 90/10 to 50/50, particularly 90 / When the ratio is 10 to 60/40, the mixture can be produced at 10,000 mPa · s or less without a sudden increase in viscosity during mixing, and when the ratio is 85/15 to 65/35, the dissolution time during compounding is short. This is preferable because deterioration of the odor and color of the raw material used due to heat can be suppressed.
[0026]
【Example】
Examples 1 to 15 and Comparative Examples 1 to 7
Detergent compositions having the compositions shown in Tables 1 to 3 were prepared according to a conventional method, and evaluated for foaming properties, feeling in use, and low-temperature stability as described below.

B: The foam amount is large.
C: The foam amount is slightly small.
D: The foam amount is small.
(Usability)
A: Good feeling in use.
B: Feeling somewhat good.
C: Bad usability.
[0029]
(3) Low-temperature stability test The detergent composition was put in a glass bottle, stored at 5 ° C. for 15 days, taken out from 5 ° C., left at room temperature (25 ° C.) for 1 hour, and visually evaluated for appearance by the following criteria.
:: transparent ○: slightly turbid △: slightly turbid ×: precipitates and separates
