Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a bar-shaped cosmetic and a method for producing the same, and aims to obtain a bar-shaped cosmetic that is hard to break and can be used economically. be.

BACKGROUND ART Conventionally, bar-shaped cosmetics have been produced by extrusion molding or injection molding by using an oil or wax such as fat, wax, or hydrocarbon as a binder or structuring agent, blending powder components with this, and extrusion molding or pouring.
Oil delta tube sticks, which are molded using a T-shape, are common. This Oil Delta Tive bar-shaped cosmetic has recently been desired to have a soft feel on the pores, so 1.
There is a tendency to add a large amount of oil during the formation of III. As a result, the strength of the bar-shaped cosmetic itself becomes soft, and if used as is, it will stain hands or break, so a protective body such as making it into a pencil shape or storing it in a dispensing container has been indispensable. However, if the oil content in the pencil shape increases, the oil may seep into the coated shaft, causing the stick to become thin.Also, it takes a certain amount of time to manufacture the pencil shape, making it difficult to manufacture quickly. was difficult. Also, for products that use a feeding container, the cost of the container is higher and there is always a clearance between the stick and the container, so
It has disadvantages such as sometimes breaking, easily breaking when extended for a long time, and the container itself being larger than a stick, making it bulky to carry.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems. The purpose of this invention is to obtain a bar-shaped cosmetic that can be manufactured without the need for an expensive container and that does not break. By coating the outer periphery of the stick with a film to prevent hands from getting dirty, the stick's strength is increased and a slim-shaped cosmetic bar is made possible.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention covers the outer peripheral surface of the chi-tick-shaped cosmetic with a thermoplastic resin, a wax, or a covering material made of a thermoplastic resin and wax. The method for producing this bar-shaped cosmetic is as follows:
The coating material is fixed to the outer periphery of the stick-shaped cosmetic by heat-melting a thermoplastic resin, wax, or a coating material made of a thermoplastic resin and wax, and immersing the stick-shaped cosmetic in this hot-melted resin. be.

Function There are two types of coating materials used in the present invention: thermoplastic resins and waxes, and since both are applied directly to the outer periphery of the cosmetic stick, those with high safety are preferred.

As the thermoplastic resin, the covering material that can be used in the present invention is preferably one that is transparent, glossy, has strong film performance, has adhesive properties, and has good adhesion to the stick. This coating material includes acrylic amphoteric resin, acrylic anionic resin, sodium polyacrylate, ronone-modified maleic acid resin, Metquin ethylene maleic anhydride copolymer, alkyd resin, polyester resin, epoxy resin, carbonic acid resin, ketone Resin, polyisoanate resin, polyethyl resin, polyurethane resin, epoxy-modified silicone resin, acrylic-modified alkyd resin, vinyl acetate, urethane type acrylic resin, styrene resin, butyral at resin, vinyl chloride resin, vinylidene chloride, ethyl cellulose, hydroxypropyl cellulose,
It is made of polyvinyl methyl ether, polyvinyl pyrrolidone, or vinyl pyrrolidone-vinyl acetate copolymer, and the film strength of this coating material is adjusted by the type and amount of plasticizer that is miscible with each resin. Examples of the plasticizer include heptalic acid ester, sebacic acid ester, anopic acid ester, phosphoric acid ester, aliphatic dibasic acid ester, polyester compound, epoxy compound, silicones, polyethylene glycol, and the like.

As a wax, even if you hold the stick directly in your hand,
Since it is necessary to have a melting point that does not melt at body temperature, it has a melting point of 50℃ or higher and has good adhesion to Suitsuta.
It is desirable that the material has sufficient hardness when used as a coating material. This wax includes beeswax, carnauba wax, candelilla wax, Montan"7, paraffin wax, ozokerite, ceresin, microcrystalline wax, Japanese wax, polyethylene powder, sucrose fatty acid ester, hydrogenated oil, palmitic acid, stearic acid,
Behenic acid, cetaryl, stearyl alcohol, polyethylene glycol (average molecular fi14000~aoo
o).

The bar-shaped cosmetics used in the present invention include lipsticks, eyeshadow sticks, eye liners, eye brows, lip liners, 7-and-a-half makeup sticks, as well as eye creams, antiperspirant sticks, and puff neem sticks. This includes cosmetics such as sticks.

Example Next, the present invention will be explained in more detail with reference to Examples.

), and the melted coating material (1) does not flow out, but the stick (3) connects the lower end of the H2 bar (4) and the melted W1W (2) through the pulp that can be easily inserted. Also, on the outside of the hopper (4), there is a
) and position the ejecting pin (5) for ejecting the stick (3) into the dissolving tank (2). The stick (3) is pushed out, the stick (3) is dipped into the melted coating material (1), and the coating material (1) is attached to the outer periphery of the stick (3). Next, melted coating material (1)
The stick (3) is moved through a rubber pulp (6) through which it can be easily penetrated, onto a curved belt (7), and on this belt (7) the covering material (1
) is dried and solidified. This operation is repeated 5 to 10 times to adhere the coating material (1) to the stick (3).

Next, the colored polyester film fragrance is added to the coating material (1) in the dissolution tank (2), and this coating material (1) is transformed into the dried and solidified coating material (1) by the same operation as above.
A rod-shaped cosmetic (8) can be obtained by repeatedly adhering it to the outer periphery 2 to 3 times and drying and solidifying it.

Repeat this process 2 to 3 times, and finally immerse the stick (3) once more in the coating material (1) in the dissolution tank (2) with the titanium mica pearl agent and fragrance added, and dry. By solidifying,
A rod-shaped cosmetic (8) can be obtained.

The bending strength of the rod-shaped cosmetic (8) formed by the method described above and the stick not covered with the coating material (1) was measured using a rheometer.

a+) By attaching a coating material to a bar-shaped cosmetic stick, such as 645g or more, the strength of the bar-shaped cosmetic product is greatly improved, and it has sufficient functionality as a bar-shaped cosmetic product that does not require a protective body. It has been confirmed that it has. Further, the thickness of the coating material (1) according to the present invention can be freely adjusted by the number of times of dipping into the melted coating material (1), and the thickness is 0.1 to b. By adding colorants, pearlescent agents, glitter, fragrances, etc. to the product, the product value can be further improved. In addition, in the manufacturing method of Example 1, the melted coating material (1
) is suitable for high viscosity liquids having a coating viscosity of about 1000 cp to 10000 cp, and the manufacturing method of Example 2 is suitable for low viscosity liquids having a coating viscosity of 1000 cp or less.

Effects of the Invention Since the present invention is constructed as described above, it does not use a covered shaft like a pencil type, and the stick does not become thin, and it is possible to manufacture SII in a short period of time, and it is possible to use an expensive container. Even if you don't use it, it won't break or sip.
A bar-shaped cosmetic can be obtained. In addition, even if you hold the cosmetic stick directly, your hands will not get dirty due to the presence of the coating material, and by covering the outer periphery of the stick with the coating material,
Since the strength of the stick can be increased and it is also possible to omit the use of a container, it is possible to obtain a stick-shaped cosmetic with a slim shape.
