Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning composition, more specifically, a cleaning composition containing a phosphate ester surfactant and a sarcosine surfactant, which has excellent foaming power, rapid foaming properties, cleaning power, etc. Focus on cleansing compositions that are gentle on the skin.

Recently, it has been recognized that phosphate ester surfactants, which are a type of anionic surfactant, are extremely mild surfactants with low irritation to the skin, and are used as a part of detergent compositions. It is used as. However, this phosphate ester surfactant has several disadvantages, including poor foaming properties, especially rapid foaming, which is an essential performance for detergent composition v/JV. However, as a surfactant for detergent compositions, it has not yet been satisfactory.For this reason, we have sought to improve the performance of detergent compositions containing it while taking advantage of the properties of the phosphorus ester-based surfactant. It was hoped that 42j! would improve.

The present inventors conducted extensive research to solve the above-mentioned drawbacks regarding cleaning compositions using phosphate ester surfactants, and as a result, unexpectedly, they discovered that sarcosine, an anionic surfactant of the same type, If a surfactant is used in combination, the drawbacks of the cleaning composition, such as the lack of rapid foaming properties, can be improved.
However, he discovered that the characteristic of low irritation to the skin remained the same, and completed his invention.

That is, the present invention comprises the following components (A) and (B), (A)
The following general formula (Ij or (lI)) (wherein R1+R2 and R3 each represent a saturated or unsaturated hydrocarbon group having 8 to 18 carbon atoms, and X and Y each represent hydrogen, an alkali metal, ammonium, or a carbon number 2 or 6
(B) a phosphate ester surfactant coated with the following general formula ωD R5 (formula where R4 is a saturated or unsaturated hydrocarbon group having 9 to 19 carbon atoms, R5 is hydrogen or a saturated or unsaturated hydrocarbon group having 1 to 4 carbon atoms, and 2 is hydrogen, an alkali metal, ammonium or The present invention provides a cleaning composition containing Al having a hydroxyalkyl group having 2 or more carbon atoms.

As the phosphoric acid ester surfactant which is the component (A) of the present invention, one having an added mole of ethylene oxide of 0 to 6 is preferable, and in particular, one having no added ethylene oxide and having a carbon number of 12 to 6 is preferable. 14 alkyl M'fr: *Those who do are preferable. Preferred specific examples of component (A) include sodium 7- or dilauryl phosphate, mono-

When this component (A) is used, the compounds represented by the above formula (1) and formula (II) are mixed in a weight ratio of 1020 to 5:5, with an opening of 10:0 to 7:6. In addition, as the sarcosine surfactant which is the component (B) of the present invention, in the formula (2), R400- has 12 to 12 carbon atoms.
In 14, R3 is preferably a methyl group, and specific examples thereof include sodium lauroyl sarcosine, potassium lauroyl sarcosine, lauroyl sarcosinate ethanolamine, triethanolamine lauroyl sarcosine, sodium myristoyl sarcosine, potassium myristoyl sarcosine, myristoyl sarcosine. Examples include jetanolamine and myristoylsarcosine triethanolamine.

The detergent composition of the present invention is not particularly limited in its dosage form, and may be in a conventionally known dosage form, such as a solid detergent, a powder/granule detergent, a paste detergent, a liquid detergent, etc. I can do it. The cleaning composition of the present invention can be prepared by blending all of the components (A) and (B) according to the known method according to the above dosage form, and further blending and adding each optional component as necessary. It is well prepared.

When the cleaning composition is a powder cleaning agent, the blending amount of component (A) is 5 to 50% by weight (hereinafter simply referred to as H), especially 1
0 to 40% is preferable, and in the case of paste cleaning agents,
-80%, especially 40-70%, and for solid/powder cleaning agents, 60-95%, especially 70-90% is preferable. The ratio is (A):(B)=10:1~4:6, %:1~
The ratio is preferably 5:5.

Optional ingredients that can be blended into the cleaning composition of the present invention and 17 (
c) In addition to water, examples include higher fatty acid salts and algylamine.

Next, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited to these Examples.

Example 1 Liquid detergent A liquid detergent was prepared with the following composition, and the foaming power was measured by varying the type and blending ratio of the phosphate ester surfactant and the sarcosine thread surfactant. The results are shown in the first garment.

Composition: Ethanol 5% water
Conditions and method for measuring residual foaming power: A 15% water bath solution of the sample detergent was prepared, and this solution 100-
into a graduated cylinder. Next, a stirring blade was placed in the solution, and while the blade was reversed every 5 seconds, the stirring blade was stirred for 60 minutes.
Stir for a second to generate bubbles, and measure the total volume of the bubbles produced. A foaming detergent is obtained.
