KR0120275B1 - Fragrance spray using microcapsule - Google Patents

Abstract

The spray preparation is produced that micro capsules of 1-10 Pm containing an aromatic or a deodorant are emulsified in water with addition of a binder for coating the surface of capsules. The prepared emulsion of the capsules coated with the binder is sprayed over the target object, such as car seat, curtain, guilt, clothes, to stay in adhesion until the capsules are crushed by impact. When crushed, the capsules emit into air the aromatic or deodorant to give a fragrance or deodorize the air.

Description

Long-lasting fragrance and deodorant spray using microchamber

1 is a perspective view of a portion of the microcapsules fractured.

2 is a state in which microcapsules are attached to a substrate such as fibers.

3 is a state in which the microcapsules attached to a substrate such as fibers are awakened and the contents are diffused in the air.

1: Aroma, deodorant, etc. 2: Microcapsules wall material

3: binder layer 4: substrates such as fibers

The present invention is intended to continuously maintain the aromatic, deodorant material, and more specifically, the aromatic or deodorant material is contained in a very small spherical microcapsules having a diameter of about 1-10㎛ and microcapsules and a small amount of binder Suspended in water together and sprayed on the object by using a propeller or sprayer, the microcapsule is attached to the target object by the binder layer, and the microcapsules are broken when the microcapsules are broken by external friction. Its purpose is to allow the contents (fragrance, deodorant) to be diffused in the air to obtain a continuous fragrance and deodorant effect.

Conventional fragrance spray is a dilution of fragrance alone or in water or organic solvent and sprays it onto the object using a propeller or spray bottle to give the fragrance. In order to solve this problem, there is a Japanese Patent Application Laid-Open Publication No. 4-200468 to solve this problem. As the Japanese patent data show, after about 7 days, most of the fragrance is blown away and only 15% is left, which is about 15% in one day in the case of conventional spray only. Compared to the previous one, Although it may be referred to as a property spray, it also has a problem of completely volatilizing after a limited period of time after spraying once.

The present invention solves the problems of the conventional directional, deodorant spray is described in detail based on the embodiment and the accompanying drawings as follows.

1 is an illustration of a microcapsule containing a variety of substances, such as odor, deodorization, (1) indicates the internal material of the microcapsule, (2) is a polymer material forming the wall of the microcapsules, the size is 1-10 It is about 탆 and spherical in shape.

When the small microcapsules were suspended in water together with the low temperature adhesive binder on the object, water was evaporated and a binder layer 3 was formed on the surface of the microcapsules to be firmly attached to the object.

In FIG. 2, a part of which is attached to the object and is broken by an external force, and the contained material is released, thereby obtaining a desired effect.

EXAMPLE

Emulsify 9 g of jasmine flavor in 30 g of 10% gelatin aqueous solution, and then add 30 g of 10% aqueous arabic rubber solution to the solution. The solution is slowly added to 140 ml of 40 ° C. distilled water and stirred at 2400 rpm. After the solution is uniformly emulsified, the pH of the solution is adjusted to 4.3 with 10% acetic acid, then quenched to 5 ° C., 1 ml of 30% formalin is added, the pH of the solution is adjusted to 9 with 10% caustic soda and 1 ° C. per minute up to 50 ° C. After raising the ratio to one night, the resulting aromatic microcapsules were dried and sprayed with a spray dryer.

3 g of the aromatic microcapsules, 1.7 g of Helizarin Binder, and 0.3 g of sosium laury benzene sulfonate are dispersed in 95 ml of distilled water. As the microcapsules are spread out and moisture evaporates, a binder layer is formed on the surface of the microcapsules and firmly adheres to the object.

In this state, when external force is applied to the microcapsules, as shown in FIG. 3, the whole is broken and the contents contained in the capsule are released and diffused in the air to obtain a desired effect. As it is not lost, it is destroyed little by little as it is applied to external force, so that the effect on the desired persistence can be maintained. In particular, spraying microcapsules containing aromatic fragrance into car seats, curtains, quilts, and clothes only once will continuously give fragrance while using them. It is a very beneficial invention that greatly contributes to resource saving.

Claims (1)

Permanent fragrance, spray of deodorant using a microcapsule, characterized in that the fragrance, deodorant material is placed inside the 1-10㎛ microcapsules and suspended together with a low temperature adhesive binder to form a binder layer on the outside.
