Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a detergent composition, and more particularly, to a detergent composition containing a phosphoric ester surfactant and hydroquine sulfobetaine, which has foaming power, low temperature stability, and This invention relates to a cleansing composition that has an excellent feel on the skin, hair, etc. after use.

[Prior art and points of interest]

Phosphorus ester surfactants have long been known to be mildly irritating to the skin, and are used as main ingredients in shampoos, skin cleansers, etc.
-9033, 57-47959).

It is also known that phosphate ester surfactants have hair conditioning properties and can be used as auxiliary agents for shampoos (Japanese Patent Application Laid-open Nos. 56-145995 and 56-163198).

Incidentally, phosphate ester surfactants are generally obtained as a mixture of a monoester and a diester, and the alkyl phosphate ester contains dialkyl phosphoric acid, which has poor water solubility and poor foaming power. Therefore, when using an alkyl phosphate ester as a cleaning agent base for shampoos, skin cleansers, etc., use one with as much monoester content as possible, or increase water solubility by adding ethylene oxide to the alkyl group. You need to use what you have.

Even if such a specific alkyl phosphate ester is used, if it is used alone as the main component of a cleaning agent, there are generally problems with foaming power, low-temperature stability, etc., so it is necessary to add an auxiliary agent. A method has been proposed to
No. 1991, JP-A-57-49698, JP-A No. 58-10
No. 3598, No. 59-74196).

However, although both of these methods improve the performance when compared to using the alkyl phosphate ester alone, they have a lower foaming power compared to other general surfactant-based cleaning agents. There have been problems such as insufficient low-temperature stability or loss of the inherent hypoallergenic properties of alkyl phosphate esters. Among these methods, the method using sulfobetaine as an auxiliary agent (Japanese Patent Publication No. 58-51991) is relatively superior in terms of increasing foaming power and improving low crystallization stability. In the production of sulfobetaine, propane sultone, which is feared to be carcinogenic, must be used, making industrial production difficult.

[Means for solving problems]

The present inventors conducted research on cleaning compositions using phosphate ester surfactants to solve the above-mentioned problems, and found that if a specific hydroquine sulfobetaine is combined with the detergent composition, The present invention was completed based on the discovery that the surfactant exhibits excellent foaming power, low-temperature stability, etc., and does not cause any change in the low irritation to the skin and hair that phosphate ester surfactants have.

That is, the present invention provides the following components (A) and (B) (A) having the following general formula (1) or (1) FL, -(OCH2CH,)(3-0-P-OY
