Description

TECHNICAL FIELD [0001] The present invention relates to a cosmetic comprising a polyester polyether polymerized foam,

The present invention relates to a cosmetic product comprising a polyester polyether polymerized foam, and more particularly to a cosmetic product containing a foamed foam for supporting a liquid cosmetic material, which can be used by supporting a liquid or solid cosmetic composition such as a solution, emulsion, And the like.

Conventionally, a liquid cosmetic composition has been mainly filled and stored in a vacuum container, a pump container, or a glass container. However, there is a disadvantage that the containers are inconvenient to carry. In recent years, there has been a growing demand for a liquid cosmetic composition that is easy to carry, as the necessity of making or modifying the cosmetic composition easily increases even when going out.

As a container that can easily carry the liquid cosmetic composition, a fact type container can be considered. In order to carry a liquid cosmetic composition on a fact type container, it is necessary to determine whether the cosmetic composition that can be used in the container is supported, whether the cosmetic composition can be well packed on the carrier, whether the carrier can homogeneously carry the cosmetic composition And whether or not a suitable amount is discharged when taking the cosmetic composition from the carrier.

In order to meet these considerations, it has recently been found out that a foamed foam obtained by foaming a synthetic resin is excellent in filling ability, retention ability and excretion ability, and thus a synthetic foam foamed foam is used as a carrier for a liquid cosmetic composition.

Among them, a technique relating to cosmetics containing a foamed foam using a polyether polyol as a carrier of a cosmetic composition is known. However, when such a polyether-based polymer foamed foam is used as a carrier of a liquid cosmetic composition, it has disadvantages such as poor durability and mechanical strength, and swells when a liquid cosmetic composition is loaded. In order to overcome such disadvantages, There has been a demand for foaming foam technology of < RTI ID = 0.0 >

BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be described in more detail with reference to the accompanying drawings.

The present invention relates to polymeric polymer foamed foams of polyester ethers; And a liquid cosmetic composition carried on the foamed foam, that is, a polyester ether polymer foamed foam prepared from a mixed polyol of polyester polyols and polyether polyols; And a liquid cosmetic composition carried on the foamed foam.

In one embodiment of the present invention, a method for producing a cosmetic product comprising a foamed foam for supporting a liquid cosmetic material, which can be used by supporting a liquid or solid cosmetic composition such as a solution, an emulsion, a gel, a cream or a suspension, It is characterized by its fulfillment.

(a) Polyester polyols were placed in a chamber, the air was taken out at a temperature of 55 to 65 ° C, and the mixture was cooled at a pressure of 0.1 to 0.2 kPa for 60 minutes. Thereafter, the temperature was lowered to 25 to 35 ° C, Preparing a polyester polyol by soaking under a pressure of 2 to 3 kPa for 48 hours;

(b) Polyether polyols were placed in a chamber and allowed to cool for 60 minutes under a pressure of 0.1 to 0.2 kPa at a temperature of 15 to 25 ° C. Then, nitrogen was supplied and the mixture was allowed to settle for 48 hours under a pressure of 2 to 3 kPa. Preparing a polyol;

(c) preparing a tank by injecting a foaming agent, a catalyst, and a surfactant into the tank, respectively, according to the demand for filtration;

(d) The polyester polyol, the polyether polyol, the blowing agent, the catalyst and the surfactant are sequentially added to the mixing and stirring tank according to the compounding ratio, and then the mixture is stirred at a temperature of 22 to 24 캜 and a pressure of 3 kPa in the tank at 5000 rpm Stirring the resultant, putting it in a mold and continuously blowing it;

(e) aging the foamed foam formed after the foaming step is completed for 48 hours;

(f) cutting the foamed foam; and

(g) supporting the liquid cosmetic composition on the foamed foam to prepare a cosmetic product

The blending of the polyester polyol and the polyether polyol at a weight ratio of 3: 7 to 6: 4 is carried out by mixing 0.2 to 0.4 parts by weight of a foaming agent, 0.2 to 0.4 parts by weight of a catalyst, And 2 to 4 parts by weight of a surfactant.

At this time, when the mixing ratio of the polyester polyol and the polyether polyol is out of the threshold value, there is a disadvantage in that the pore size of the foam foam to be finally produced is not uniformly formed, and the density is not sufficiently secured, .

In addition, there is a problem that the repulsive elastic modulus is so low that the feeling of use after impregnation of the liquid cosmetic is deteriorated and that the liquid cosmetic may not be uniformly discharged after the impregnation. The pore size is one of important factors for supporting the liquid cosmetic material. Preferably, the optimum pore size for carrying the liquid cosmetic material has an average pore size of 900 to 1,100 μm, and the number of pores formed is 60 to 80 ppi The filler, the filler, and the emissivity of the liquid cosmetic composition are excellent.

In addition, the rebound resilience of the foamed foam is preferably in the range of 40 to 45%, because the restoration can be easily performed in the initial state after compression.

In addition, the foaming foam carrying liquid cosmetic material should have a proper compressive strain, and the compressive strain should preferably be in the range of 30 to 40%. The reason is that it can have a soft touch feeling in use.

Preferably, the density is 40 to 45 kg / m 3, the hardness is 75 to 80 (measured by JSI K6301A), the tensile strength is 220 to 230 Kpa , And a water absorption rate of 300 to 400%. The reason is that a large amount of cosmetics can be carried.

According to the embodiment of the present invention described above, the average pore size is 900 to 1,100 μm, the pore number of 60 to 80 ppi (pore per inch), the density is 40 to 45 kg / m 3 (based on the density unit) The foamed foam for supporting a liquid cosmetic material having physical properties such as a tensile strength of 45 to 45%, a compressive strain of 30 to 40%, a hardness of 75 to 80 (measured by JSI K6301A), a tensile strength of 220 to 230 Kpa and a water absorption rate of 300 to 400%.

Hereinafter, the present invention will be described in more detail with reference to preferred embodiments.

In the above Table 1, the pore size and pore number were measured by WI-QA-14 (ASTM standard) method, and the water absorption rate was measured by measuring the foamed foam with a size of 3 cm x 3 cm, After drying for a period of time, the initial weight (A) was measured and stored in distilled water at 25 ° C for 48 hours. After removing the surface water, the weight (B) was measured. Finally, it was calculated using the following equation (1).

(Equation 1) Absorption (%) = (B-A) / A x 100

In addition, the hydrolysis resistance is a result of testing the resistance of the foamed foam by impregnating it with water, and comparing the degree of breakage when the foam was rubbed with a sponge after being left at room temperature for 15 days.

The maintenance resistance was obtained by visually comparing the degree of breakage when the foam was rubbed with a sponge after the cosmetic composition was impregnated with the foam composition (resistance was tested and allowed to stand at room temperature for 15 days). As a result of the hydrolysis resistance and the preservation resistance shown in FIG. 1, it was found that the foamed foam according to the embodiment of the present invention is excellent in resistance to moisture and cosmetic composition as compared with the conventional foamed foam made of a single component.
