JPH03173565A - Atomizer containing perfume - Google Patents

Abstract

PURPOSE:To enjoy a comfortable aroma by microcapsulating a perfume used in an atomizer. CONSTITUTION:The perfumes include ketones, aldehydes, esters, lactones, ethers, synthetic musks, and hydrocarbons, and to facilitate the capsulation, the perfumes can be mixed with other hydrophobic mediums to form core materials. The hydrophobic mediums include ketones such as benzyl benzoate and dioctyl phthalate, mineral oils such as kerosene, paraffin, and naphtene oil, aromatic hydrocarbons such as alkylated biphenyl and alkylated naphthalene, amides such as N,N-dimethylocytylamide, plants such as cottonseed oil, and others. The microcapsules include non-gradually releasing microcapsules in which the perfumes as the core materials are released only when the capsules are broken by a pressure such as friction, and gradually releasing microcapsules in which the perfumes are gradually released through porous wall films even in the state where the capsules are not broken.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an atomizer containing a fragrance, and particularly to an atomizer that allows the user to enjoy a pleasant fragrance.

[Conventional technology]

2. Description of the Related Art Conventionally, one of the methods for imparting a fragrance to clothes or a room is to spray a fragrance or a liquid containing a fragrance onto an object using the pressure of air, a propellant, or the like.

However, in the case of this conventional method, ■ The fragrance tends to scatter over a wide area when spraying (it tends to have a surprisingly strong odor, which is the target of young people).■ The odor does not disappear immediately after being sprayed. It is too strong and may cause discomfort.■ It has many problems, such as the fragrance evaporating too quickly and the smell becoming impossible to perceive immediately.

[Problem to be solved by the invention]

An object of the present invention is to provide a sprayer with a built-in fragrance that does not have the above-mentioned problems and allows the user to enjoy a pleasant fragrance.

[Means to solve the problem]

This is a fragrance-containing atomizer that contains a fragrance as a component, and is characterized in that the fragrance is contained in microcapsules.

[Effect]

As a result of research, the present inventor found that by microcapsulating the fragrance used in the atomizer, even if the fragrance is scattered to other than the target object, it is strong (no smell),
We have also discovered that the intensity of the odor immediately after spraying can be controlled within a comfortable range.

Microcapsules that can be used in the present invention include non-sustained release microcapsules that release the core fragrance only when the capsule is ruptured under pressure such as friction, and non-sustained release microcapsules that release the fragrance core material only when the capsule is ruptured under pressure such as friction. One example is sustained-release microcapsules, which release fragrance gradually through a porous wall membrane. It is preferable to use non-sustained release microcapsules because they can be enjoyed alternately and do not cause discomfort due to continuous sniffing of the same odor.

The microcapsules used in the present invention can be prepared by a conventionally known coacervation method (for example, U.S. Pat. No. 2,800,457).
Interfacial polymerization method (e.g., Japanese Patent Publication No. 38-19574, Japanese Patent Publication No. 4244)
No. 6, Special Publication No. 42-771, Special Publication No. 49-4513
3, etc.) 1n-situ polymerization method (for example, Japanese Patent Publication No. 36-9158, Japanese Patent Publication No. 51-907)
9, Japanese Patent Publication No. 53-84881, etc.).

Examples of the fragrance used in the present invention include ketones, aldehydes, esters, lactones, ethers, synthetic musks, hydrocarbons, and the like.

■Aliphatic ketones: 2-heptane, 3-octanone, 2
- Undecanone et al.

■Aromatic ketones: anisyl acetone, benzylidene acetone, p-methylacetophenone, p-methoxyacetophenone, etc.

■Alicyclic ketones: α-ylon, β-ylon, T-ylon, α-damascone, β-damascone, α-damascenone, β-damascenone, theasvirone, etc.

■Terpene ketones: menthone, carvone, prebon, etc.

■Hydrocarbons: limonene, camphene, pinene, etc.

can be mentioned. Moreover, two or more types of these fragrances can also be used in combination.

For ease of encapsulation, it is also possible to mix the perfume with other hydrophobic media to form the core material.

Such hydrophobic media include, for example, benzyl benzoate,
Esters such as dioctyl phthalate, dioctyl adipate, and isoamyl isovalerate. Ketones such as acetophenone, methylcyclohexanone, and holon. Mineral oils such as kerosene, paraffin, and naphthenic oil. Aromatic hydrocarbons such as alkylated biphenyls, alkylated naphthalenes, and diphenylalkanes. Amides such as N,N-dimethyloctylamide. Examples include vegetable oils such as cottonseed oil, and various auxiliary agents such as antioxidants, ultraviolet absorbers, and colored dyes may also be added.

The perfume-containing microcapsules are usually sprayed as an aqueous dispersion, but they can also be used as an organic solvent dispersion.

The dispersion liquid used in the present invention may be a dispersion liquid consisting only of microcapsules and a dispersion medium, but it is more preferable that the dispersion liquid has a tendency to strongly adhere to a young object and cause the microcapsules to scatter as dust. Examples include dispersions containing suppressed microcapsules and a binder.

Examples of the binder include water-soluble binders, latexes, and oil-soluble binders.

Examples of water-soluble binders include gelatin, albumin, casein, agar, gum arabic, alginate, starch, oxidized starch, etherified starch, esterified starch, carboxymethylcellulose, hydroxyethylcellulose, polyvinyl alcohol, polyvinylpyrrolidone, and polyacrylic. acid, polyacrylamide, ethylene-

Among these, systems using water-soluble binders are particularly preferred since the components can be removed extremely easily by washing or the like after use.

Various auxiliary agents such as antioxidants, ultraviolet absorbers, preservatives, thickeners, and dispersants can be added to the dispersion of the present invention, if necessary.

In the present invention, in addition to microencapsulated fragrances, non-encapsulated fragrances and fragrances included in clathrate compounds such as cyclodextrins can also be used in combination.

Although the particle size of the microcapsules used in the present invention is not particularly limited, those having an average particle size of 0.5 to 50 μm are usually used.

The ratio of microcapsules to dispersion medium in the present invention is not particularly limited, but is usually in the range of 1 to 100 parts by weight of capsules to 100 parts by weight of dispersion medium. or,
If a binder is used, its blending ratio is 1 capsule.
The binder is in the range of 1 to 10,000 parts by weight per 1,000 parts by weight.

The dispersion of the present invention can also be used as a laundry paste by appropriately selecting the type and amount of the binder.

The sprayer of the present invention may be a sprayer or a sprayer that uses air, but the most preferred one is an aerosol type that uses a propellant.

Examples of propellants include those known in the art, such as fluorocarbon gas and LP.
G, chloromethyl gas, dimethyl ether, carbon dioxide gas,
Argon etc. are used.

〔Example〕

The present invention will be explained below with reference to Examples, but the present invention is not limited to these examples. In addition, parts indicate parts by weight.

Example 1 An internal phase liquid (core material) was prepared by dissolving 120 parts of an adduct of xylylene diisocyanate and trimethylolpropane (manufactured by Narita Pharmaceutical Co., Ltd. [trade name: Takenate D-110NJ) in 100 parts of geranyl acetate. .

10% aqueous fi1 of partially saponified polyvinyl alcohol (Kuraray (Kurare product name: PVA-217EEJ'))
220 parts of water was added to 80 parts to obtain an emulsion having an average particle size of 2 μm. This emulsion was heated to 60° C. with stirring, and reacted for 3 hours to obtain a microcapsule dispersion containing geranyl acetate.

Next, the above dispersion liquid and LPG as a propellant were sealed in an aerosol container and sprayed toward a handkerchief to flavor it. The odor during spraying was so strong that it could be mistaken for a fragrance, and the obtained handkerchief also had an odor intensity so strong that it could be mistaken for a fragrance. Furthermore, the handkerchief that had been injected for two hours was completely odorless, but by rubbing it with your hands, the capsules were destroyed and you could feel the fragrance again.

[Comparative example]

Geranyl acetate 100 instead of the capsule dispersion in Example
An aerosol was prepared in the same manner as in the example except that the sample was used, and the aerosol was sprayed onto a handkerchief to flavor it. The odor during spraying was so strong that it was unpleasant and distracting, and so was the resulting handkerchief. Furthermore, the handkerchief that had been sprayed for two hours was completely odorless, and even when it was rubbed with hands, no odor was detected at all.
