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 effectively removes offensive odors such as odors during defecation, odors from garbage, odors from pets, cigarettes, etc.

[0002]

2. Description of the Related Art As a method for removing offensive odors (smelling during defecation, smells of garbage, smells of pets, cigarettes, etc.) generated at home, a very strong fragrance is used. A method of concealing a malodor has been mainly adopted by using a substance having the substance as a deodorant and mixing the strong aroma with the malodor.

However, since such a conventional deodorant uses an aroma stronger than the intensity of the malodor, the overall odor intensity after mixing with the malodor is only the malodor before mixing. It is much stronger than strength and often feels uncomfortable as a result. In addition, although the bad odor before mixing can be concealed, the odor after mixing is often felt as another unpleasant odor. Thus, the conventional deodorants have not been able to fundamentally improve the unpleasant odor.

Therefore, the present invention does not increase the overall odor intensity after mixing with a bad odor to an unpleasant level, and further, the odor after mixing does not become another unpleasant odor.
An object is to provide a deodorant composition capable of masking offensive odors.

[0005]

Therefore, as a result of intensive studies by the present inventors, the deodorant satisfying the above-mentioned requirements is obtained by using a combination of compounds belonging to two specific groups as deodorant components. They have found that a composition can be obtained and completed the present invention.

That is, the present invention has the following components (A) and (B) (A) as deodorant components: α-pinene, d-limonene, 2-phenylethyl alcohol, benzyl alcohol, linalool, geraniol and citronellol. And a flavor selected from α-hexylcinnamic aldehyde (B): l-menthol, l-menthone, l-carvone, 1,8-cineole, camphor, anethole, cinnamic alcohol, cinnamic aldehyde, borneol, eugenol, It is intended to provide a deodorant composition comprising a fragrance selected from n-bornyl acetate and isobornyl acetate in a total amount of 0.001 to 2.00% by weight based on the total composition.

The present invention also provides a deodorant composition containing an anionic surfactant and an amphoteric surfactant as a cleaning component in addition to the above deodorant component.

EXAMPLES Hereinafter, the present invention will be described in detail with reference to examples, but the present invention is not limited to these examples.

Example 1 A composition having the composition shown in Tables 2 and 3 was prepared. The composition shown in Table 2 was used for deodorizing effect, and the composition shown in Table 3 was used for deodorizing effect and detergency. It was evaluated by.

<< Evaluation Method of Deodorizing Effect >> 1 ml of the composition was dropped into a wide-mouthed 5 liter bottle filled with cigarette odor or fecal odor, and the perceived level of the bad odor of the air in the bottle and the strength of the entire odor were measured. Sensory evaluation was performed by 10 panelists. Cigarette butts and feces were placed in 5 liter wide-mouthed bottles and left at room temperature for 1 hour to be filled with odor, and then evaluated. In this case, the amount of cigarette butts or feces to be put in the bottle was adjusted so that the perceived level of cigarette odor or fecal odor in the bottle was 4, and the intensity of odor was 3. The evaluation was performed according to the following evaluation criteria, and the average values are shown in Tables 2 and 3.

(Perceived offensive odor) 1: No offensive odor 2: Slight offensive odor 3: Offensive odor 4: Strong offensive odor

(Overall odor intensity) 1: Very weak 2: Weak 3: Moderate 4: Strong 5: Very strong

<Evaluation Method of Detergency> As a model of stain, tempura oil was applied to an iron plate and baked at a temperature of 180 ° C. for 20 minutes to form an almost dry film to prepare a model-contaminated plate. The composition was dropped on the model-contaminated plate fixed horizontally and left for 40 seconds. Then, the floating dirt was lightly removed with absorbent cotton, and its cleaning power was evaluated. The detergency was shown in Table 3 as an average value of five model contaminated plates, with the cleaning rate being the percentage of the area where the stain was removed with respect to the area occupied by the composition when the composition was dropped on the model contaminated plate.

[0031]

[Table 2]

[0032]

[Table 3]

From the above results, it is understood that the deodorant composition of the present invention has an excellent deodorizing effect and detergency. On the other hand, it can be seen that the comparative product does not have a sufficient deodorizing effect or has a strong overall odor and does not have sufficient detergency.

[0034]

EFFECTS OF THE INVENTION The deodorant composition of the present invention does not increase the overall odor intensity after mixing with a bad odor to an unpleasant level, and further, the odor after mixing has another unpleasant odor. The odor can be masked without becoming an odor. In addition, by further blending a specific cleaning component, it is possible to have both a sufficient deodorizing effect and an excellent cleaning effect, and it is possible to remove not only the bad odor but also stains that often cause the bad odor. Become.
