Technical Field
The present invention relates to a liquid detergent composition for clothing.
Background
As liquid detergents, consumers generally expect excellent overall cleaning performance, and therefore, generally use enzymes in detergent formulations to improve detergency.
Since the acidic pH can cause enzyme instability in the detergent, and the enzyme denaturation can cause enzyme activity loss, most of the existing enzyme-containing liquid detergents select neutral or alkaline product pH, which is more favorable for enzyme stability. However, since a detergent composition having an acidic pH has a bactericidal and deodorant function and can neutralize stubborn stains such as urine alkali, it is preferable to select an acidic detergent in some use environments. At present, a small amount of enzyme-containing detergent products have an acidic pH, but a large amount of surfactants, solvents, stabilizers and the like are needed to stabilize enzymes under acidic conditions, but the smearing detergency of the detergent products is not ideal, and the detergent products are not environment-friendly.
Patent document 1 discloses an enzyme-containing low pH liquid cleaning composition containing a surfactant system containing an anionic surfactant, a cleaning enzyme, and an organic acidulant, and having a neat pH of 2 to 6. As a result, it was found that the effect of improving the stability of the enzyme at low pH can be obtained by selecting an appropriate acidifying agent.
Patent document 2 discloses a low pH compact fluid laundry detergent composition, and further, an enzyme is added to the composition, and the stability of the enzyme in the composition is evaluated. As a result, it was found that anionic surfactant-based concentrated laundry detergents can be formulated at low pH using branched anionic surfactants and can provide improved enzyme stability.

Patent document 2: CN105408461A
Disclosure of Invention
On the other hand, stubborn stains on the collar, the armpit and the like cannot be effectively removed only by washing with water, and the stains can be more effectively removed only by directly applying a detergent on the stains, namely, a liquid detergent with strong decontamination performance is required to be applied. While a large amount of nonionic surfactant or solvent is helpful to enhance the stability of the protease and maintain the activity of the protease, a large amount of nonionic surfactant and polyol solvent often also hinder the performance of the protease in the coating process, so that the coating decontamination performance is not enough. In addition, the low temperature stability of the liquid detergent is also a practically important property according to the environmental requirements.
However, the above patent documents 1 to 2 do not mention the low temperature stability and the smear removal performance of the enzyme-containing low pH detergents.
Accordingly, an object of the present invention is to provide a liquid detergent composition for clothing, which has excellent enzyme stability, smear detergency performance and low-temperature stability at acidic pH.
The inventor finds that: when the pH is weakly acidic, a certain amount of anionic surfactant and protease are mixed with amphoteric surfactant and organic acid in a certain proportion, so that the excellent enzyme stability can be maintained, and the smearing decontamination performance and the low-temperature stability are excellent.
The liquid detergent composition for clothing of the present invention contains the following components (a) to (E):
(A) 0.01 to 25% by mass of an anionic surfactant;
(B) a protease;
(C) an organic acid or a salt thereof having a molecular weight of 160 or less, in an amount of 0.01 to 3% by mass;
(D) water; and
(E) an amphoteric surfactant, and a surfactant component,
wherein the mass ratio (C)/(B) of the component (C) to the component (B) is 70 or more and 521 or less,
the mass ratio (E)/(B) of the component (E) to the component (B) is not less than 31,
the composition has a pH of 7 or less at 25 ℃.
According to the liquid detergent composition for clothing of the present invention, the anionic surfactant, the protease, the specific organic acid, and the amphoteric surfactant are blended in the above composition ratio and the specific content, so that excellent enzyme stability, smear detergency performance, and low-temperature stability can be obtained.

Ingredient (E)
The component (E) in the liquid detergent composition for clothing of the present invention is an amphoteric surfactant, and in the present invention, the stability of the enzyme in the liquid detergent composition can be improved by containing the component (E) in a certain proportion in the liquid detergent composition.
The reason why the amphoteric surfactant can improve the stability of the enzyme in the liquid detergent composition is not clear, and is presumed as follows: the charge of the hydrophilic group of the anionic surfactant contained in the liquid detergent composition acts with the protease, the space structure of the protease is changed, the activity of the protease is reduced, and the action degree is in direct proportion to the charge intensity; in addition, the hydrophobic group of the anionic surfactant interacts with the nonpolar group inside the protease to inactivate the protease. By adding the amphoteric surfactant to the liquid detergent composition, the positive charge group of the amphoteric surfactant is electrostatically attracted to the hydrophilic group of the anionic surfactant, thereby preventing or inhibiting the interaction between the anionic surfactant and the protease, and improving the stability of the enzyme in the liquid detergent composition.
The amphoteric surfactant as the component (E) may be a betaine amphoteric surfactant or an amine oxide surfactant having a linear or branched hydrocarbon group, and among them, an amine oxide surfactant having a linear or branched hydrocarbon group is preferably used.

As the amine oxide type surfactant having a linear or branched hydrocarbon group, the linear or branched hydrocarbon group is preferably a linear alkyl group. Examples of such amine oxide-type amphoteric surfactants include hexyldimethylamine oxide, octyldimethylamine oxide, decyldimethylamine oxide, dodecyldimethylamine oxide, tetradecyldimethylamine oxide, hexadecyldimethylamine oxide, N-octylmorpholine-N-oxide, N-decyldorpholine-N-oxide, N-dodecylmorpholine-N-oxide, and N-tetradecylmorpholine-N-oxide.
From the viewpoint of improving the enzyme stability and the smear-removing performance of the liquid detergent composition for clothing, the mass ratio (E)/(B) of the component (E) and the component (B) in the liquid detergent composition is 31 or more, preferably 35 or more.
