Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a detergent composition having excellent foaming properties and containing an α-sulfolipid fatty resin salt acylated peptide.

Dialkali metal salts of α-sulfo fatty acids have high resistance to hard water, are stable, and have good wetting and permeability; however, they are virtually insoluble in water at room temperature, and have very weak detergency and foaming power. It is a surfactant. Therefore, in order to take advantage of the excellent properties of α-sulfolipid fat resin salt and to increase its foaming power, a cleaning agent was proposed in which it was combined with an organic ampholyte (Japanese Patent Application Laid-Open No. 71003/1983). However, even when this organic ampholyte is used in combination, satisfactory foaming power and detergency cannot be obtained.

The present inventors have conducted extensive experimental research in order to further enhance the excellent properties of α-sulfolipid fatty resin salts and to obtain a detergent composition with excellent foaming performance and cleaning performance. It has been discovered that a detergent with extremely desirable foaming power and detergency can be obtained by combining a fatty resin salt acylated peptide, and the present invention has been achieved.

That is, the present invention provides (a) general formula (wherein R is an alkyl group having 12 to 16 carbon atoms, M and M
' is a water-soluble salt-forming cation selected from magnesium and substituted or unsubstituted ammonium groups, which may be the same or different. - sulfolipid fat resin salt and (b) general formula (in the formula, R' is an alkyl group having 9 to 19 carbon atoms, R" is a hydrogen atom, a methyl group or an ethyl group, M" is an alkali metal,
Alkaline earth metals and unsubstituted or average molecular weight 2
000 or less) in a weight ratio of both components (a)/(b) of 9/1 to 515. be.

Component (A) represented by the above general formula +11 used in the composition of the present invention is a fatty acid in which R is an alkyl group having 12 to 56 carbon atoms, in other words, a higher fatty acid having 14 to 18 carbon atoms. , wherein the salt-forming cations M and M' are anionic surfactants selected from magnesium and substituted or unsubstituted ammonium groups, respectively.

Further, the alkyl group R having 12 to 16 carbon atoms is usually linear, but may be branched, and
Even if it contains fewer or more carbon atoms,
If the average of all of them is within the range of 12 to 16, the effects of the present invention will not be impaired. Therefore, in the present invention, the carbon number of R of 12 to 16 is essentially the average carbon number. range. Ingredient (a) having an average carbon number of less than 12 or more than 16 is not preferable because no mutual effect with the component (b) used in combination can be obtained, and no significant improvement in foaming properties can be expected. Dialkali salts such as sodium and potassium are also disadvantageous because they do not provide mutually beneficial effects and have low cleaning performance.

The anionic surfactant represented by 2 (11) is obtained by sulfonating the corresponding higher fatty acid in which R has an average carbon number of 12 to 16 with 803 gas to introduce a sulfonic acid group at the α-position.
It can be easily produced by neutralizing with a magnesium compound or substituted or unsubstituted ammonium. As the substituent for the substituted ammonium, lower alkanols are preferred, and ethanol residues are particularly preferred. Examples of such component (a) include α-sulfomiristic acid, α-sulfobalmitic acid, α-sulfostearic acid,
Examples include magnesium salts, diammonium salts, dimonoethanolamine salts, ditriethanolamine salts, triethanolamine l/2 magnesium salts, etc. of α-sulphohydrogenated beef tallow fatty acids, α-sulphohydrogenated palm oil fatty acids, etc. . These may be used alone or in combination of two or more (1. In addition, in the composition of the present invention, the component (B) used in combination with the above component (A) is the general formula An acyl peptide represented by (■), where R' has 9 to 9 carbon atoms.
The alkyl group of No. 19, that is, the acyl group R'OO, is a higher fatty acid residue having 10 to 20 carbon atoms. If the number of carbon atoms in the acyl group is smaller, the foaming properties of the composition in combination with component (A) will be poor, and if the number of carbon atoms exceeds 20, the water solubility will decrease, resulting in a decrease in foaming properties. This is not desirable because it causes From the viewpoint of foaming properties and detergency, the acyl group preferably has 12 to 14 carbon atoms. Also, y' in formula (If)
is an ammonium group substituted with an alkali metal such as sodium or potassium, an alkaline earth metal such as magnesium or calcium, an ammonium group, or one to three organic groups such as lower alkyl or alkanol, but the substituted Or an unsubstituted ammonium group is preferred.

R'' Furthermore, the divalent group -N-A-COO- of the formula (■) is
Residues of oligopeptides, polypeptides, and their N-lower alkyl substituted products having an average molecular weight of 2000 or less. If the average molecular weight exceeds 2000, the foaming properties will be poor, which is not preferable. In particular, the molecular weight of the portion represented by RI'Ikko-A-000M'' in the formula is 20
A molecular weight of 0.00 or less is preferable, and if the molecular weight is an average value for the component (b) used, the object of the present invention can be effectively achieved, so it essentially means the entire average molecular weight.

In the cleaning composition of the present invention, the weight ratio (a)/(b) of the above component (a) and component (b) is 971 to 5.
It is important that the content be within a range of 15%. If the content exceeds this range, the additive foaming effect will not be obtained and the desired detergency will not be exhibited, which is not preferable.

Hereinafter, the present invention will be explained in more detail with reference to Examples.
The present invention is not limited to these embodiments.

Note that foaming properties in Examples and Comparative Examples were evaluated based on the following test method.

Foaming Test Method: Spread 5 ounces of butter on one plate. In a vat with a diameter of 30 crm and a depth of 12 crn filled with cleaning solution No. 31, the temperature of the solution was kept at 25°C, the sponge was compressed 10 times to create bubbles, and the surface of the dish contaminated with butter was washed 10 times. The back surface was rubbed with a sponge five times, and the foam height was measured immediately after washing the fifth plate, and this was taken as the foaming power.

In addition, in the test, all cleaning liquids were prepared and evaluated so that the total surfactant concentration i was 0.066% by weight.
