Abstract

PROBLEM TO BE SOLVED: To obtain a deodorant composition excellent in eliminating an animal odor by incorporating a metal complex of glycine into the same. SOLUTION: A metal which forms a mono- to trivalent cation is preferable as the metal for forming the metal complex of glycine. Alkali metals, alkaline earth metals, group IIIA metals, and group 4 transition metals are especially preferable, such as Na, K, Mg, Al, Fe, Cu, and Zn. The most preferable among them are Zn, Cu, and Al, especially Zn. At least one kind of metal complex of glycine is used, preferably in an amount of 0.03-5 wt.% of the composition. Preferably, a surfactant is incorporated into the composition to remove an oil attached to animal hair to thereby cause the metal complex, the acting component, to penetrate to the surface of the hair. Preferably, the amount of the surfactant incorporated is 0.05-5 wt.% of the composition. Water is preferable as the medium for above ingredients.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant composition which has an excellent deodorizing effect on animal odor and provides a good feeling of use.

[0002]

2. Description of the Related Art Deodorants proposed so far have a deodorizing effect on the axillary odor, foot odor, hair odor and the like of the human body, but have a deodorizing effect on animals such as dogs. As described above, when the odor of the substance that generates the odor is strong, the deodorizing effect is often insufficient. Therefore, there is a growing demand for a deodorant having an effective deodorizing action against strong odors such as animal odors. In particular, when an animal such as a dog having a strong odor is bred at home as a pet, deodorization is inevitable. However, since deodorization by washing with shampoo in water is troublesome and cannot be performed frequently, a deodorant that can easily and simply deodorize is demanded instead.

Accordingly, an object of the present invention is to provide a deodorant composition having an excellent deodorizing effect on animal odor.

[0004]

The present invention has achieved the above object by providing an animal deodorant composition containing a metal complex of glycine.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION As the metal constituting the metal complex of glycine used in the deodorant composition of the present invention, a metal forming a monovalent to trivalent cation is used. A class III metal, a Group IIIA metal or a transition metal of the fourth period of the periodic table is preferably used. Sodium, potassium, magnesium, calcium, aluminum, iron, copper, zinc and the like are used. Of these,
In particular, zinc, copper and aluminum, especially zinc, are preferred. One or more glycine metal complexes can be used.

The metal complex of glycine is present in the composition in an amount of 0.03
-5% by weight, especially 0.3-3% by weight,
It is preferable in terms of the balance between the deodorizing effect and the solubility or dispersibility.

In US Pat. No. 4,565,693, it is described that zinc glycine has a deodorizing effect on axillary odor, foot odor and the like. There is no recognition. The present inventors have made various studies and found for the first time that a substance that is a source of animal odor is the same component as a substance that is a source of human body axillary odor, foot odor, and body odor. It has been found that a metal complex of glycine has a very effective deodorizing effect even on the odor of animal odor.

The method of preparing the glycine metal complex used in the present invention will be described. For example, when zinc glycine is prepared as the glycine metal complex, zinc oxide and an excess amount of glycine are used as starting materials in the United States. Patent 4,
No. 565,693, a method of reacting under the conditions described in column 3, lines 9 to 20, or using a zinc halide such as zinc chloride and glycine as starting materials, column 3, lines 50 to 53 of the same specification. Reaction method according to the conditions described in the line,
A method of reacting an aqueous solution of zinc carbonate and glycine as a starting material under the conditions described in column 3, lines 59 to 62 of the same specification, or the like is used.

The deodorant composition of the present invention is a composition containing the above-mentioned glycine metal complex as an active ingredient and effective for deodorizing animal odor using water as a medium. The composition of the present invention may further comprise a surfactant, if necessary, to remove the oil adhering to the hair of the animal, and to coat the metal complex of glycine as an active ingredient on the surface of the hair. It is preferable in that it can penetrate up to As the surfactant, those having high (veter) medical safety are used. In particular, nonionic surfactants, especially fatty acid ester type nonionic surfactants, polyoxyalkylene type nonionic surfactants, alkyl alkanols An amide type nonionic surfactant or an alkyl glucoside type nonionic surfactant is preferably used.
One or more of these surfactants may be present in the composition in an amount of from 0.05 to
It is preferable to add 5% by weight, especially 0.1 to 1% by weight.

As the fatty acid ester type nonionic surfactant, an ester of a polyhydric alcohol and a fatty acid is used.

As the above polyoxyalkylene type nonionic surfactant, polyoxyethylene polyoxypropylene glycol, polyoxyethylene sorbitan fatty acid ester, polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether and the like are used.

Preferred specific examples of the alkylalkanolamide type nonionic surfactant include palm kernel oil diethanolamide.

Preferred specific examples of the alkyl glucoside type nonionic surfactant include lauryl glucose,
Oleyl glucose and coconut fatty acid glucose are exemplified.

In the deodorant composition of the present invention, silicone oil can be used, if necessary. Polysiloxane or the like is used as the silicone oil. Specific examples of the polysiloxane include dimethyl polysiloxane and methyl hydrogen polysiloxane. Various modified silicone oils such as fluorinated silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, alcohol-modified silicone oil, and alkyl-modified silicone oil can also be used, but it is preferable to use unmodified silicone oil. . One or more silicone oils can be used.

When a polysiloxane is used as the silicone oil, the degree of polymerization is preferably from 30 to 20,000, particularly from 80 to 3,000, because of low viscosity when producing or using the deodorant composition. It is preferable because it is easy and gives a feeling of being exposed to the skin and hair.

[0016] The silicone oil is contained in the composition in an amount of 0.1 to 0.1%.
10% by weight, particularly 0.3 to 3% by weight,
It is preferable in that it gives an appropriate smooth feeling to the skin and coat.

The deodorant composition of the present invention may further contain, if necessary, preservatives such as parapenes, lower alcohols such as ethanol, fragrances and buffers.
It is preferable that these components are added to the composition in an amount of 0.01 to 10% by weight, particularly 0.03 to 5% by weight, from the viewpoint that the action of the components is sufficiently and sufficiently exhibited.

The deodorant composition of the present invention can be sprinkled with a suitable amount on the site where the deodorant is to be deodorized. An appropriate amount of the odorant composition is sprinkled on a brush, and the portion to be deodorized is brushed with the brush, and the odorant composition is air-dried to achieve the deodorizing effect. Further, the feeling of use such as combing the hair becomes good. Therefore, the deodorant composition of the present invention is suitably used as a deodorant shampoo composition that does not require rinsing and wiping.

The deodorant composition of the present invention has a viscosity at 20 ° C. of 1 to 50 mPa · s, particularly 1 to 5 mPa · s. It is preferable because it is easy to handle. The viscosity is measured by a B-type viscometer using a BL adapter at a condition of 60 rpm.

Although the pH value of the deodorant composition of the present invention is not particularly limited, it is generally preferably 4 to 7 from the viewpoint of (veter) medical safety. Phosphoric acid, lactic acid, citric acid and the like are used as the pH adjuster.
