Disclosure of Invention

Problems to be solved by the invention

The following analysis is provided in view of the present disclosure.

Pump foamers for forming a detergent such as body soap (bath soap) or hand soap (hand soap) into a foam and discharging (discharging) the foam have been widely used. In order to obtain a good feeling of use by the user from the foam discharged from the pump foamer, the foam is required to have elasticity (elasticity) and not to be easily defoamed at the time of washing. However, when a humectant, a polymer, or the like is blended in order to improve the foam quality (foam quality), the detergency of the detergent tends to be lowered. A detergent with reduced detergency cannot effectively or sufficiently remove ingredients such as cosmetics that are difficult to wash. Therefore, a detergent composition having a high detergency and capable of discharging foam having a good foam quality is required.

In the aqueous liquid detergent composition described in patent document 1, high-quality foam cannot be discharged by a pump foamer.

In the detergent composition described in patent document 2, for example, sufficient detergency cannot be exhibited for cosmetics.

Means for solving the problems

According to the 1 st aspect of the present disclosure, there is provided a detergent composition containing (a) a fatty acid having 8 to 24 carbon atoms or a salt thereof, (B) a taurine derivative or a salt thereof, and (C) a glycerin derivative represented by the following chemical formula 1. The molar ratio of the component (A) to the component (B) is 0.5 to 2 mol based on 1 mol of the component (A).

[ chemical formula 1]

In the chemical formula shown in chemical formula 1, R¹、R²And R³Any one of them is an alkyl group, an alkenyl group or an acyl group having 4 to 15 carbon atoms, and the other 2 are hydrogen groups.

Effects of the invention

The detergent compositions of the present disclosure may be suitable for use in pump foamers. The foam discharged from the pump foamer of the detergent composition of the present disclosure has elasticity and is less likely to be defoamed during washing. Thus, the user can obtain a good feeling of use. On the other hand, the detergent composition of the present disclosure can exert high detergency even for ingredients that are difficult to wash, such as cosmetics.

A method for producing the detergent composition of the present disclosure will be described. The detergent composition of the present disclosure is not limited to a specific method, and can be prepared by a generally known method. For example, a detergent composition can be prepared by mixing the above components.

Preferably, the fatty acid taurate as a complex of the component (a) and the component (B) is previously produced and then added to the composition. For example, the fatty acid taurate can be prepared by dissolving the component (a) in water under heating and adding the component (B) to an aqueous solution of the component (a). The detergent composition of the present disclosure can be produced by adding the fatty acid taurate prepared in advance.

In some cases, the effects of the respective components are not known in the detergent composition. For example, although it is considered that the component (a) and the component (B) form a fatty acid taurate, it is difficult to directly specify which structure or action the component (a) and the component (B) adopt, or it is hardly practical. Therefore, in the case where the detergent composition of the present disclosure cannot be directly specified depending on the composition, it should be allowed to be described by its production method.

Examples

Hereinafter, the detergent composition of the present disclosure will be described by way of examples. However, the detergent composition of the present disclosure is not limited to the following examples. In the following examples, examples in which the detergent compositions of the respective test examples are applied to washing of cosmetics are described, but the composition of the present disclosure is not limited to cosmetic use. The unit of the content of each component shown in each table is mass%.

[ test examples 1 to 9]

A detergent composition was prepared and discharged from a pump foamer, and the discharged foam was evaluated according to the following criteria. In test examples 1 to 9, the influence of the fatty acid N-methyltaurate on the quality of vesicles was mainly examined. The pump foamer used is of the type commonly used, in which foam is dispensed from a nozzle by manually pushing the nozzle into the container from above downwards. The viscosity of each composition was measured using a Brookfield type viscometer (spindle No. 1, rotation speed 60rpm) at 30 ℃. The composition and evaluation of each composition are shown in table 1 and table 2. The evaluation of the foam quality shown in the table was carried out according to the following criteria. The component (H) is represented by a chemical formula corresponding to the chemical formula shown in the above chemical formula 2, and AO in which PO represents the chemical formula shown in the above chemical formula 2 is an oxypropylene group.

[ fineness of bubble ]

The detergent composition was discharged from the pump foamer, and the fineness of the discharged foam was visually confirmed:

a: the bubbles are very fine;

b: the bubbles are fine;

c: slightly intermingled with large bubbles;

d: a little of large bubbles are mixed;

e: many large bubbles are mixed.

[ elastic force of bubble ]

The detergent composition was discharged from the pump foamer, and the elasticity of the discharged foam was confirmed by pressing with a finger:

a: the bubble has stronger elasticity;

b: the bubble has a slightly stronger elasticity;

c: the bubble has elasticity;

d: the elasticity of the bubble is weak;

e: the bubble has no elasticity.

[ persistence of foam ]

When the detergent composition was discharged from the pump foamer and the cosmetic-applied face was washed with the discharged foam, the foam persistence was confirmed:

a: the persistence of the bubble is very long;

b: the persistence of bubbles is long;

c: the bubbles were somewhat easy to defoam;

d: the foam is easy to defoam;

e: the foam immediately defoams.

[ detergency ]

The face of a panelist who applied a cosmetic (foundation) was washed with the foam discharged from the pump foamer using the detergent composition, and the removability of the cosmetic was confirmed:

a: the removal of the cosmetic product is very good;

b: the cosmetics are well removed;

c: removing the cosmetics properly;

d: the cosmetics are difficult to remove;

e: the cosmetics cannot be removed.

In test example 1 in which (a) fatty acid and (B) taurine derivative were not added, that is, no fatty acid taurate was formed, the detergency was improved, but the foam quality was unsatisfactory. On the other hand, in each of test examples 2 to 9 in which the fatty acid (a) and the taurine derivative (B) were added and the fatty acid taurate was considered to be formed in the composition, the foam quality was improved. It is thus assumed that: the fatty acid taurate helps to improve the quality of the foam.

Consider that: when the fatty acid (A) is contained in an amount of 0.5% by mass or more, preferably 1% by mass or more based on the mass of the composition, the foam quality can be improved. Consider that: when the taurine derivative (B) is 0.5% by mass or more, preferably 1% by mass or more based on the mass of the composition, the foam quality can be improved.

The molar ratio of the component (a) to the component (B) in the composition is preferably 0.1 mol or more, more preferably 0.5 mol or more of the component (B) to 1 mol of the component (a). The molar ratio of the component (a) to the component (B) is preferably 10 mol or less, more preferably 5 mol or less, based on 1 mol of the component (a).

In test example 8 in which the glycerin derivative (C) was not added, the detergency was lowered. On the other hand, in test examples 9 and 10 in which the (C) glycerin derivative was added, the detergency was improved without deterioration of the foam quality. In particular, in test examples 9 and 10, compositions having sufficient detergency could be obtained even though (F) the nonionic surfactant and (G) the oily component were not added.

Consider that: if the content of the glycerin derivative (C) is 0.5% by mass or more, preferably 1% by mass or more, based on the mass of the composition, the detergency can be sufficiently improved. Consider that: the glycerin derivative (C) may be 5% by mass or less based on the mass of the composition.

In addition, in examples 8 to 10, the blending amount of (A) the fatty acid and (B) the taurine derivative was increased as compared with examples 2 to 7. It is thus assumed that: the fatty acid (a) may be contained in an amount of at least 7% by mass of the composition. Consider that: the taurine derivative (B) can be contained in an amount of at least 7% by mass or less.

[ Table 3]

[ test examples 11 to 17]

In test examples 11 to 17, the effects of components other than components (A) to (C) were tested.

When test example 11 in which the inorganic salt (J) was not added was compared with test examples 12 to 15 in which the component (J) was added, the compositions of test examples 12 to 15 improved the foam elasticity. It is thus assumed that: the addition of the inorganic salt is effective for improving the foam quality. Consider that: the component (J) is preferably 0.05% by mass or more, more preferably 0.1% by mass or more, relative to the mass of the composition.

Among test examples 11 to 15, the composition of test example 13 had the best foam quality. This is considered to be due to the influence of the increase in the amount of the alkylene oxide derivative of the component (H). It is thus assumed that: the component (H) is more preferably 0.05% by mass or more, more preferably 0.5% by mass or more, more preferably 1% by mass or more, and further preferably 2% by mass or more, based on the mass of the composition.

In test example 17 in which the pH buffer (I) was not added, a detergent composition having good foam quality and detergency was also obtained. On the other hand, in test example 16, when the component (I) was added to the composition of test example 17, the foam became finer and the foam quality was improved.

[ Table 5]

According to test examples 2 to 7 and 9 to 17, it is considered that: the content of the (D) anionic surfactant is preferably 2% by mass or more based on the mass of the composition. The content of the component (D) may be 12% by mass or less based on the mass of the composition. Consider that: the content of the (E) amphoteric surfactant is preferably 1% by mass or more based on the mass of the composition. The content of the component (E) may be 8% by mass or less based on the mass of the composition. It is considered that the anionic ratio is preferably 0.2 or more. It is considered that the anionic ratio is preferably 0.9 or less.

In test examples 2 to 7 and 11 to 17, (F) a nonionic surfactant and (G) an oily component were added. When compared with test examples 9 and 10 in which the component (F) and the component (G) were not added, the detergency was improved in test examples 2 to 7 and 11 to 17. It is thus assumed that: the component (F) and the component (G) are effective for improving detergency. Consider that: the component (F) is preferably 2.5% by mass or more, more preferably 3% by mass or more, more preferably 3.5% by mass or more, and more preferably 4% by mass or more, based on the mass of the composition. Consider that: the component (G) is preferably 0.2% by mass or more, more preferably 0.3% by mass or more, and further preferably 0.5% by mass or more, based on the mass of the composition. It is considered that the ionic ratio is preferably 0.35 or more. It is considered that the ionic ratio is preferably 0.9 or less.
