Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a technical field of a cleaning composition. More specifically, the present invention relates to a cleaning composition in which generation of an unpleasant odor due to deterioration of a fragrance compounded therein is suppressed.

[0002]

2. Description of the Related Art At present, a fragrance is blended in various external compositions such as cosmetics.
This is not an exception in a detergent composition for removing dirt attached to a person, such as a face wash or shampoo. That is, the role of a scent is very important in a detergent composition, as the scent is a product characteristic that is first touched by consumers, together with the shape and design of the container.

It is known that a fragrance compounded in an external composition deteriorates with the lapse of time due to, for example, the influence of light or temperature. In particular, in the above-mentioned detergent composition, the fragrance compounded deteriorates. The degree is large and often accompanied by unpleasant odor.

[0004]

As a cause of the deterioration of the fragrance in such a detergent composition, for example, a detergent for cleaning which is incorporated in a relatively large amount into the detergent composition, or a detergent having such a surfactant, It is assumed that the impurities, which are contained in the agent in a small amount, affect the specific components in the fragrance compounded.

[0005] Therefore, at present, a surfactant which has been treated in advance to remove a substance which is considered to be a cause of deterioration of perfume is added to a detergent composition, or a specific component causing the deterioration is removed. Attempts have been made to conduct individual tests and select and incorporate perfume that does not contain into the cleaning composition.

[0006] However, the former method of blending the treated surfactant is troublesome and disadvantageous in that the cost of the cleaning composition is increased. In the latter method, the perfume to be blended naturally is limited. Therefore, it is difficult to impart various scents to the detergent composition.

[0007] Therefore, an object of the present invention is to stabilize the perfume in the detergent composition without increasing the cost of the detergent composition and without limiting the perfume that can be blended in the detergent composition. Is to provide a means of conversion.

[0008]

Means for Solving the Problems The present inventor has made intensive studies to solve this problem. As a result, ethylenediaminehydroxyethyl triacetate, which is usually compounded in an external composition as a chelating agent, etc., is added to the detergent composition as a means for stabilizing the fragrance, thereby suppressing deterioration of the compounded fragrance. It has been found that it is possible to solve the above problem.

That is, the present invention provides a detergent composition containing ethylenediaminehydroxyethyl triacetate as a means for stabilizing a fragrance (hereinafter referred to as the detergent composition of the present invention).
I will provide a.

[0010]

Embodiments of the present invention will be described below. The detergent composition of the present invention contains ethylenediaminehydroxyethyl triacetate as a means for stabilizing the fragrance.

[0011] Ethylenediaminehydroxyethyl triacetate is an amino acid derivative that is widely used as a chelating agent and the like in external compositions such as cosmetics.

Examples of the ethylenediaminehydroxyethyltriacetate contained in the detergent composition of the present invention include sodium ethylenediaminehydroxyethyltriacetate and potassium ethylenediaminehydroxyethyltriacetate.

[0013] Regardless of the number of bound water, for example, a dihydrate, a trihydrate, or an ethylenediaminehydroxyethyltriacetate can be blended in the detergent composition of the present invention. is there.

Ethylenediaminehydroxyethyltriacetate can be synthesized by a known method, and is also commercially available and easily available [Kurewat OH300 (Teiku Chemical, Kimura Sangyo), Kyrest H (Kyrest Chemical, Matsumoto Trading), Zonone OS, OH
(Daiichi Pure Chemicals), Crewat OH35 (Imperial Chemical)
etc〕.

[0015] These ethylenediaminehydroxyethyltriacetates can be selected alone and blended in the cleaning composition of the present invention, but can also be blended in combination of two or more.

In the detergent composition of the present invention, the amount of these ethylenediaminehydroxyethyl triacetates is as follows:
It should be appropriately selected according to the specific type and amount of the fragrance to be stabilized, and other components,
Although it is not particularly limited, the 0.1% of the whole composition is generally used.
It is preferably blended in the range of from 0.01% by weight to 5.0% by weight, and particularly preferably in the range of from 0.02% by weight to 2.0% by weight. When the amount is less than 0.01% by weight of the whole composition, it is difficult to sufficiently stabilize the fragrance, which is not preferable.
It is difficult to exhibit a perfume stabilizing effect commensurate with the increase in the blending amount, which is not preferable.

The fragrance which is incorporated in the detergent composition of the present invention and which is stabilized by the above-mentioned ethylenediaminehydroxyethyl triacetate salt is not particularly limited as long as it is a fragrance which can be usually incorporated in an external composition. Is done. As described above, conventionally, the fragrance which can be usually blended in a cleaning composition is individually tested beforehand for those which have relatively good stability over time in the cleaning composition and hardly cause odor. According to the present invention, the types of fragrances that can be blended in such a detergent composition are dramatically increased, and a detergent composition having various scents is provided at low cost. Is now possible.

That is, in the detergent composition of the present invention, the presence of ethylenediaminehydroxyethyl triacetate, as described above,
It is stabilized and the odor that occurs with time, which has conventionally been a problem, is sufficiently suppressed.

Examples of natural flavors include rose oil, jasmine oil, neroli oil, lavender oil, ylang-ylang oil,
Tuberose oil, clary sage oil, clove oil, peppermint oil, geranium oil, patchouli oil, sandalwood oil, cinnamon oil, coriander oil, nutmeg oil,
Pepper oil, lemon oil, orange oil, bergamot oil,
Vegetable flavors such as oppoponax oil, vetiver oil, oris oil and oak moss oil; and animal flavors such as musk oil, civet oil, castorium oil, ambergris oil and the like can be mentioned widely.

As the synthetic fragrance, for example, limonene, β-
Hydrocarbon-based flavors such as caryophyllene; alcohol-based flavors such as cis-3-hexenol, linalool, farnesol, β-phenylethyl alcohol, geraniol, citronellol, terpineol, menthol, santalol, bacdanol, and bramanol; 2,6-nonadienal; Aldehyde-based flavors such as citral, α-hexylcinnamic aldehyde, rial, and lyal; ketone-based flavors such as β-ionone, damascon, methylionone, iron, isoesuper, acetylcedrene, muscone; benzyl acetate, methylhydroxyl Ester-based flavors such as jasmonate and methyl jasmonate; lactone-based flavors such as jasmine lactone, cyclopentadecanolide, ethylene brassate; galact solid, ambro Mention may be made of a wide oxide-based perfumes such as San.

In the cleaning composition of the present invention, one or more of these various fragrances are blended to give various scents, for example, floral scents, woody scents, shipley scents, and muges. Scent, citrus scent, green scent, fusea scent, oriental scent, fruity scent, spicy scent,
Aldehyde-based scents, animal-based scents, and the like can be freely selected, and these scents can exhibit an excellent feature that they are hardly deteriorated with time.

The amount of these fragrances in the detergent composition of the present invention can be appropriately selected and blended, and is not particularly limited.

As described above, in the detergent composition of the present invention, due to the action of ethylenediaminehydroxyethyl triacetate, these fragrances are stabilized with time irrespective of the kind of the fragrances to be blended, and can be maintained for a long time. It is possible to prevent generation of unpleasant odor.

The detergent composition of the present invention contains specific forms of the detergent composition, for example, soaps, body soaps, hand soaps, hair shampoos, hair rinses, facial cleansers, makeup removers, etc. Depending on the type of detergent for miscellaneous goods such as dishwashing and the like, generally known base components and cleaning components, and furthermore, chemicals can be blended.

For example, anionic surfactants such as alkyl sulfates, polyoxyethylene alkyl ether sulfates, acylmethyltauric acid, and N-acylglutamate; amphoteric surfactants represented by betaine surfactants Nonionic surfactants such as fatty acid alkylamides; oils such as lanolin derivatives, liquid paraffin, higher fatty acids, higher alcohols, ester oils, and silicone oils; cationic polymers such as cationized cellulose; humectants such as glycerin Agents; thickeners; viscosity modifiers; emulsions; pigments; preservatives; pH regulators; chelating agents other than ethylenediaminehydroxyethyl triacetate: agents such as trichlorocarbanide, sulfur, salicylic acid, zinc pyrithione, and isopropylmethylphenol. And the like are blended in the cleaning composition of the present invention. It can be. The specific formulation of the cleaning composition of the present invention is described in Examples.
