Description

The present invention relates to detergent compositions, especially liquid detergent compositions for clothing.

Conventionally, fragrances have been added to detergents for clothes in order to improve the feeling of washing the washed clothes. However, in recent years, an increasing number of consumers are demanding that the odors of raw materials and fragrances are weak or almost unnoticeable in laundry detergents.

On the other hand, some raw materials used in laundry detergents have a strong peculiar odor, and the peculiar odor of a mixture of anionic surfactants and alkanolamine compounds is particularly unpleasant for consumers. Since it is recognized as an odor, it has been dealt with by masking it with a relatively strong scent of fragrance. For example, Patent Documents 1 to 3 disclose a technique for masking the amine odor of a clothing cleaning agent composition with a specific fragrance such as an aliphatic alcohol, a terpene alcohol, or an acetic acid ester.

Japanese Patent Application Laid-Open No. 2005-120258 Japanese Patent Application Laid-Open No. 2003-049195 JP-A-2015-017236

However, in the techniques described in Patent Documents 1 to 3 described above, when an attempt is made to sufficiently mask the amine odor, the scent of the fragrance itself used becomes stronger.

Therefore, the present invention relates to a cleaning agent composition containing an anionic surfactant and alkanolamines while suppressing a peculiar odor due to the anionic surfactant and alkanolamines and a fragrance derived from a fragrance component.

As a result of diligent research conducted by the present inventors in such a situation, the cleaning agent composition containing an anionic surfactant and alkanolamines contains at least one selected from jasmonic acid and jasmonic acid-like compounds as main components. It has been found that by containing the fragrance composition in a constant amount ratio, not only the peculiar odors of the anionic surfactant and the alkanolamines but also the fragrance odor is hardly perceived as a cleaning agent composition.

The present invention contains the following component (A), component (B), component (C) and water, the content of component (A) is 0.4% by mass or more and 5% by mass or less, and the component (A) with respect to component (B). ) Is 0.01 or more and 0.5 or less, and the mass ratio (A) / (C) of the component (A) to the component (C) is 0.1 or more and 10.0 or less. Is what you do.
Ingredient (A): Perfume composition containing 80% by mass or more of the following ingredient (A1) Ingredient (A1): At least one selected from jasmonic acids represented by the general formula (1) and jasmonic acid analogs.

[In the formula, R ¹ represents a hydroxy group or a methoxy group, R ² represents a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms, and a broken line indicates a single bond or a double bond. ]
Ingredient (B): Anionic surfactant Ingredient (C): Alkanolamine

The detergent composition of the present invention contains an anionic surfactant and alkanolamines, and preferably suppresses a peculiar odor due to the anionic surfactant and alkanolamines and a fragrance derived from a fragrance component. Is.

[Ingredient (A): Fragrance composition]
The detergent composition of the present invention contains a fragrance composition containing 80% by mass or more of the following component (A1) as the component (A).
Ingredient (A1): At least one selected from jasmonic acids represented by the following general formula (1) and jasmonic acid analog compounds.

[In the formula, R ¹ represents a hydroxy group or a methoxy group, R ² represents a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms, and a broken line indicates a single bond or a double bond. ]

The component (A1) is a fragrance compound capable of suppressing a peculiar odor caused by an anionic surfactant and alkanolamines without strongly flavoring. In the general formula (1), R ¹ is preferably a methoxy group, and R ² is preferably a methyl group. Specifically, as the component (A1), at least one selected from the group consisting of methyl jasmonate and methyl dihydro jasmonate is preferable.

Any of the components (A1) can be used alone or in combination of two or more. The content of the component (A1) in the component (A) is 80% by mass or more, preferably 85% by mass or more, from the viewpoint of obtaining a sufficient effect of suppressing peculiar odor without causing excessive flavoring. It is more preferably 90% by mass or more, still more preferably 95% by mass or more.

(Component (A2): Perfume compound other than component (A1) whose OV value is 48,000 or less)
The fragrance composition of the component (A) can further contain one or more fragrance compounds having an odor value (OV value) of 48,000 or less as the component (A2). The component (A2) is fragrant when the content of the component (A) is less than 20% by mass in the fragrance composition of the component (A) and the content of the component (A) in the cleaning agent composition is 0.4% by mass or more and 5% by mass or less. It is a fragrance component that has a weak standing and hardly feels the scent of the fragrance, especially in the washed clothes, and can be used to give the consumer a feeling of washing as long as the effect of the present invention is not impaired. The compound corresponding to the component (A1) is excluded from the component (A2).

In the present invention, the odor value (OV value) is an index given by dividing the gas phase concentration at the saturated vapor pressure at 25 ° C. of each fragrance compound by the detection threshold concentration, and is often used by those skilled in the art of fragrance-related techniques. It is a known index. The saturated vapor pressure of fragrance compounds at 25 ° C can be calculated using The Estimates Programs Interface for Windows ver4.11 and Meylan, WM & Howard, PH (1995). Journal of Pharmacological Sciences 84, 83-92 It is obtained by the calculation method described in.

Gas phase concentrations of fragrance compounds can be measured using any known quantitative headspace analysis technique, eg, Mueller and Lamparsky in Perfumes: Art, Science and Technology, Chapter 6 "The Measurement of Odors". At pages 176-179 (Elsevier 1991).

The detection threshold in the present invention is a term often used in the fragrance industry and means the lowest concentration at which it is known that there is a substance that emits some odor.

25 g of the liquid detergent composition for clothing shown in Tables 2 to 6 was placed in PS-No. 6 wide-mouth standard bottle manufactured by Tokyo Glass Instruments Co., Ltd. The intensity of the scent derived from the fragrance component was evaluated. The evaluation was performed by 6 specialized panelists (4 men in their 20s and 30s and 2 women in their 20s and 30s) in 0.5-point increments based on the evaluation criteria shown below, and the average value was calculated.

<Evaluation criteria for the strength of peculiar odor>
0: Does not smell 1: Can be detected only by careful sniffing, but the type of odor is unknown 2: Can be perceived by careful sniffing and can understand the type of odor 3: Easy to perceive odor 4: Strong odor 5: Strong odor

<Evaluation criteria for fragrance intensity>
0: Does not smell 1: Can be detected only by careful sniffing, but the type of scent is unknown 2: Can be perceived by careful sniffing and can understand the type of scent 3: Easy to perceive scent 4: Strong scent 5: Strong scent

Regarding the strength of the peculiar odor, the passing level was set to be less than 2 in which the type of peculiar odor can be known.
Regarding the intensity of the scent, the passing level was set to be less than 3, which allows the scent to be easily perceived.

As a result of the evaluation, when the content of the component (A) was less than 0.4% by mass, the peculiar odor intensity was 2 or more, and when it exceeded 5% by mass, the scent derived from the fragrance component was strongly felt, whereas it was 0.4. In the examples of mass% or more and 5% by mass or less, the peculiar odor score was greatly reduced, and the scent derived from the fragrance component was also weak. When the content of the component (A1) in the fragrance composition was less than 80% by mass, the scent derived from the fragrance component was strongly felt.

In addition, the liquid detergent composition for clothing of Example 18 was distributed to 40 married women aged 25 to 49 years and used for 2 weeks, and then the actual feeling of use was investigated.
