JPH06181972A - Deodorant for cigarette smell - Google Patents

Abstract

PURPOSE:To provide a deodorant giving no harm to a human body and ensuring high efficiency for removing cigarette smell by causing the deodorant to contain a substance having a buffer function composed of organic acid and an alkaline metallic salt thereof, or inorganic acid and an alkaline metallic salt thereof, and further preparing the deodorant so as to have a specific pH value range. CONSTITUTION:This deodorant contains a substance having a buffer function composed of organic acid and an alkaline metallic salt thereof, or inorganic acid and an alkaline metallic slat thereof, and prepared so as to have a pH value within the range of 3 to 7. In this case, the organic acid is tartaric acid, citric acid or the like, while the alkaline metallic salt is sodium tartrate, sodium citrate or the like. The inorganic acid is phosphoric acid or the like, and the alkaline metallic salt thereof is sodium hydrogenphosphate or the like. The buffer agent composed of such substances is preferably used in the form dissolved in water and a mixed solvent of water-ethanol, or the like. As a result, a cigarette smell deodorant having an excellent deodorizing effect and high safety can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cigarette odor deodorant which is safe for human use.

[0002]

2. Description of the Related Art Conventionally, as a method for deodorizing a cigarette odor, a method using a plant extract component (Japanese Patent Publication No. 22670/1990) and a method using a fragrance component (Japanese Patent Laid-Open No. 63-6611).
5) and the like. However, the effect of using a plant extract component is insufficient when it is used as a cosmetic, and the method of using a fragrance component has a scent of people and sometimes causes disgust. Therefore, there are some problems such as not being common.

[0003]

DISCLOSURE OF THE INVENTION As a result of intensive studies made by the present inventors in view of the current situation, the cigarette odor is expressed by
Although it has a complex odor of over 100 kinds, it is usually found that the unpleasant odor of cigarettes is derived from nicotine, and if basic nicotine is controlled with a buffer, it causes a feeling of strangeness when used on the human body. And has no effect on the human body,
Moreover, the present invention has been completed by finding that the cigarette odor is sufficiently deodorized, and an object of the present invention is to provide a cigarette odor deodorant.

[0004]

The above-mentioned object is to contain a substance having a buffering capacity consisting of an organic acid and an alkali metal salt thereof, or an inorganic acid and an alkali metal salt thereof, and having a pH of 3 to 10.
Achieved by a cigarette odor deodorant characterized by being 7.

The organic acids referred to in the present invention are tartaric acid, citric acid and the like, and the alkali metal salts thereof are sodium tartrate, sodium citrate and the like. The inorganic acid includes phosphoric acid and the like, and the alkali metal salt thereof includes sodium hydrogen phosphate and the like. The buffer is preferably used by dissolving it, and the solvent may be mere water or water-
A mixed system such as ethanol may be used.

The mixing ratio is not particularly limited, but for example, in a water-ethanol system, the ethanol concentration is preferably 1 to 60% by weight. The concentration of the buffer is a necessary concentration for controlling the above pH range, but usually 0.01 to 10
%, Preferably 0.1 to 5% by weight is sufficient.

The pH of the deodorant of the present invention is 3 to 7,
If it is less than 3, it will hurt the skin and hair, and if it exceeds 7, the deodorizing effect will be inferior.

The tobacco odor deodorant of the present invention may be blended with any known components. For example, a bactericidal agent, a masking agent with an arbitrary fragrance, an oil component, a surfactant, an antiseptic agent, a saccharide, an antiphlogistic agent, a thickener, a pigment, a humectant, etc. may be appropriately blended within a range that does not impair the effects of the present invention. It is possible.

The method for applying the tobacco odor eliminating agent of the present invention is not particularly limited, but it is desirable to apply it by a method such as lotion or spray.

[0010]

EXAMPLES Next, the present invention will be described in detail with reference to examples, but the present invention is not limited thereto. still,
The blending amount is% by weight. The odor level evaluation, skin irritation test and hair damage test were carried out by the following test methods.

(1) Evaluation of odor level A hair bundle was hung in a container having a certain fixed volume, an ignited cigarette was placed, and after 10 minutes, the hair bundle was taken out to obtain hair having a cigarette odor attached. A deodorant was applied to this hair and evaluated by 10 expert panelists on the basis of the 6-level odor level shown in Table 1. As a result, the average value of 10 professional panelists was described.

(2) Skin Irritation Test A deodorant was added to a fin chamber (Finn Chamber).
r, manufactured by Taisho Pharmaceutical Co., Ltd., and stuck on the flexed side of the forearm of 10 male and female panelists for 24 hours. Removal 1
After a lapse of time, it was visually evaluated based on Table 2 and the result was panel 1
The average value of 0 persons is described.

(3) Hair damage test Using hair, the hair was immersed in a deodorant for 1 week and evaluated according to the criteria shown in Table 3. In addition, 1 experiment was implemented in 3 cases.

[Table 4]

Examples 3-4, Comparative Examples 5-6 Deodorants were produced with the compositions shown in Table 5, and the evaluation results are shown in Table 5. As is clear from Table 5, Examples 3-4 of the present invention were excellent in deodorizing effect and safety as compared with Comparative Examples 5-6.

[0020]

[Table 5]

Example 5 A spray type deodorant having the composition shown in Table 6 was produced, and the evaluation results are shown in Table 6. As is clear from Table 6, Example 5 of the present invention was excellent in deodorizing effect and safety.
