Abstract

The present invention relates to a make-up puff with a thickness of 2.4T to 3.8T and a compression rate of 30% to 70%.

Description

Cosmetic puff

The present invention relates to a cosmetic puff.

Customers who use cosmetics want to apply the cosmetics evenly and tightly to the skin, and finish the makeup with high quality.

Conventionally, the makeup cosmetic composition was applied to the contents by hand, or applied a cosmetic using a cosmetic sponge. However, in order to implement the customer's needs, we have developed an applicator combining the devices.

The present inventors have found a puff that can be most suitably used in a cosmetic device or apparatus and have completed the present invention.

It is an object of the present invention to provide a puff of a cosmetic composition.

In order to achieve the above object, the present invention provides a cosmetic puff having a thickness of 2.4T to 3.8T and a compression ratio of 30 to 70%.

When applying the cosmetic composition by applying the puff of the present invention to the device, the tapping force of the device is maximized to improve the spreadability of the cosmetic, and the cosmetic is applied evenly and smoothly. In addition, even after a time of application, there is no lifting of the makeup, so the persistence of the makeup can be maintained. In particular, the puff of this invention is excellent in water resistance and oil resistance by apply | coating a film inside. Using the puff according to the present invention can be expressed in a liquid, cream, cake, cosmetic formulation of the pressed formulation evenly and uniformly without clumping.

1 to 3 show one example for the puff of the present disclosure.

As used herein, the term "applicator" may refer to a device in which the cosmetic composition is in close contact with the skin. The applicator includes a case in which the applicator is operated by a power such as a battery or electric power, or by tapping directly by a user of the applicator.

As used herein, the term "puff" is applied to the device to bring the cosmetic composition into close contact, and may be combined with or separated from the applicator, and may be used interchangeably, but is not limited thereto. The "puff" herein also refers to makeup primer, makeup base, foundation, skin cover, lipstick, lip gloss, face powder, lip liner pencil, eyebrow pencil, eye shadow, cheek color, compact powder, twin cake, fact, It can be applied to Powder Pact, Eyebrow, Eyeshadow, Concealer, Blusher, Powder Foundation or Airless.

The present invention, in one aspect, relates to a cosmetic puff having a thickness of 2.4T to 3.8T and a compressibility of 30 to 70%.

In the present specification, T is a unit meaning thickness and means mm. The thickness numerical range means a thickness when no pressure is applied to the cosmetic puff. If the thickness of the puff is less than 2.4T, the adhesive strength between the cross sections of the puff is weak, which weakens the durability against constant tapping. If it exceeds 3.8T, the tapping strength is weakened and the makeup effect is lowered. In view of the above, the puff which is one aspect of the present invention is preferably 2.45T to 3.75T thickness, 2.5T to 3.7T thickness, 2.55T to 3.65T thickness, 2.6T to 3.6T thickness or 2.65T to It can have a thickness of 3.55T.

In the present specification, the thickness of a puff refers to the thickness of a single puff, and when two or more puffs are bonded and overlapped, the thickness of one puff is referred to.

As used herein, the term "compression ratio" may refer to the degree or ratio of compression compared to the initial thickness when the polyurethane sponge is compressed. In the present invention, the compressibility can be determined by measuring the initial thickness of the sponge and the thickness after compression when the sponge is applied at a temperature of 250 ° C. for 5 seconds in a vertical direction.

If the puff compression rate is less than 30%, the thickness may be thick and the impact may be reduced, and if the compression rate exceeds 70%, the density may be high due to the high density, and may have a weak adhesive strength when thermally bonding the cross sections. In view of the above, the puff of one aspect of the present invention may preferably have a compression ratio of 32 to 68%, a compression ratio of 34 to 66%, a compression ratio of 36 to 64% or a compression ratio of 38 to 62%.

Compression rate is to increase the density by applying pressure to a foam of a certain thickness, the higher the pressure becomes thinner. The puff of the present invention has an optimized thickness and compression ratio so that when the thickness is reduced by applying pressure, the air layer of the foam pores decreases to prevent a decrease in the feeling of impact.

In one aspect of the present invention, the floc may have a thickness of 0.5 to 2 deniers and a length of 0.5 to 1.5 mm.

"Denier" is an international unit used to express the thickness of the fiber, denoted by the sign d or D. The standard weight is 450 m and the unit weight is 0.05 g as 1 denier. That is, denier

D = (L / W) * (w / ℓ)

(L: standard length, W: unit weight, w: weight of fiber, ℓ: length of fiber)

Is calculated. Therefore, the greater the weight, the greater the fineness, the lighter the thinner and the smaller the fineness. When the floc has the thickness and length under the same conditions as the present invention, the cosmetic composition may be uniformly applied to make the skin smooth, and the irritation to the skin is small. Specifically, in the present invention, if the floc is less than 0.5 denier, it is too thin and elastic, so that agglomeration occurs due to cosmetics and sebum, and if it exceeds 2 denier, the soft feeling of use is inferior. In addition, in the present invention, when the floc is less than 0.5mm in length, the effect of sweeping the contents is reduced, and agglomeration of the flocked fibers occurs, and when it is more than 1.5mm, a soft feeling falls, and a powdering phenomenon occurs.

Hereinafter, the configuration and effects of the present invention will be described in more detail with reference to Examples. However, the following examples are provided only for the purpose of illustration in order to facilitate understanding of the present invention, and the scope and scope of the present invention are not limited thereto.

Example 1 Preparation of Cosmetic Puff

Polyurethane was prepared as a raw material of a puff, and the cosmetic puff which is a two-layered structure of the 1st layer 10 and the 2nd layer 20 was manufactured. The polyurethane first layer 10 is double-sided, has a lower end in contact with the skin and an upper end not in contact with the skin, and a film film is applied to the upper end. The second polyurethane layer 20 was double-sided, and a circular fastener 21 was drilled in the center thereof. After contacting the upper end part to which the film film of the 1st layer was apply | coated and the lower end part of the 2nd layer, and contacting, cutting and sealing were simultaneously performed by the metal mold | die according to the size.

Experimental Example 1

The cosmetic puff according to Example 1 was prepared in various physical properties to measure the feeling of impact. Physical properties and measurement results of the cosmetic puff are shown in Tables 1 and 2 below. In Tables 1 and 2, the density and compression ratio of polyurethane are manufacturer's data, and the thickness is measured by ruler. Hair length (mm) and thickness (denier) are also manufacturer's data. The feeling of striking (tap strength) evaluated the degree of force transmitted to the skin when the sponge was hit on the skin. Adhesive strength was measured by peeling the puff after washing with neutral detergent. Tactile and crumbness measured the sensitivity test, and evaluated the softness and crumbness when applied to the face of 20 people using cosmetics. If the thickness of the first layer 10 (see Fig. 1) is 4.0T or more, the sponge will absorb the feeling of impact, and the feeling of impact will drop rapidly, and 2.8T is the optimum thickness for mass production. Although the adhesive strength is the same polyethylene film, the adhesive strength is good at 3.6T or less, whereas the adhesive strength is weak at 4.0T or more. Here, the thickness of 4.0T thicker than 3.6T means that the extrusion rate is low, which means that there are many air layers. Therefore, during bonding, the air layer affects the adhesive strength, thereby weakening the adhesive strength.
