WO2016148495A1 - Cosmetic composition applicator comprising impermeable layer - Google Patents

Abstract

The present invention provides a cosmetic composition applicator comprising an impermeable layer. According to the present invention, an application layer of a cosmetic composition applicator absorbs the cosmetic composition, but a flexible layer may block the cosmetic composition so that the cosmetic composition is not absorbed. Thus, moisture durability may be procured, flexibility and comfortability of the applicator may be continuously procured, and since the absorption of liquid contents into the cosmetic composition applicator is suppressed, the rate of transmission to skin may be enhanced.

Description

Cosmetic composition applicator comprising a non-transmissive layer

The present invention relates to a cosmetic composition applicator.

As the portability of the conventional liquid cosmetic composition spreads and the use of the cosmetic composition applicator increases, the form of the applicator to be used also seeks convenience. In the past, there was a built-in applicator of the portable container. During use, the elasticity and comfort of the applicator decreased, and there was a disadvantage in reducing the makeup effect.

The fact-type container that can easily carry the cosmetic composition is embedded with a thin processed sponge to carry and make-up, or to easily make-up externally. The cosmetic composition applicator embedded in the container may be stained with oil and moisture, sebum on the face and external dust during use, or may be stored for a long time after being embedded in the container. Moreover, the low viscosity contents are diffused, and the compatibility of the low viscosity contents with the applicator affects the service life of the cosmetic composition applicator.

The cosmetic composition applicator may generally be composed of an application layer of a foam foam including fine pores to suit the cosmetic effect, an elastic layer of the foam foam to make makeup applied and adhere well, and a cover layer to prevent contamination of hands. Foam foam is a porous foam may vary depending on the degree of foaming, foaming method, etc., can be classified into a foam suitable for application and a foam suitable as a carrier. Due to the nature of the foam, the contents are absorbed, and in particular, the low viscosity liquid contents are easily absorbed. The cosmetic composition applicator including the elastic layer has good elasticity and comfortable feeling at the time of initial use, but gradually foam foam absorbs the contents. As a result, the elasticity is gradually lowered and the pleasant feeling may be lowered. The foam of the elastic layer is mainly used ester (ester) -based polyurethane. However, ester base polyurethanes are poorly resistant to moisture. Thus, when the polyurethane of the elastic layer is used as an ether-based polyurethane resistant to moisture, there is a problem that it is not sealed by thermal processing.

Experimental Example 1 Comparative Experiment for Contents Moisture Absorption of Applicator Containing Non-Transmissive Layer

15 g of the liquid content (cosmetic composition) was absorbed as much as possible to absorb the non-transparent layer non-applied applicator (puff) (Comparative Example 1) and the non-transmissive layer applied applicator (puff) (Example 1), and the maximum absorbed weight was measured. The degree of absorption of the contents was compared. Content delivery rate in this experimental example was calculated as follows. The results are shown in Table 2.

[Equation 1]

Content delivery rate = skin application amount (g) / quantity to take contents with applicator (g) * 100

In the following Comparative Example 1 and Example 1, the coating layer, the elastic layer and the cover layer except for the inclusion of the non-transparent layer have the same configuration. Specifically, each coating layer is a polyurethane having a cell size of 100 to 200 µm in a foamed urethane foam in a wet process. The non-transmissive layer is a cellless polyurethane sheet which is a polyurethane having a thickness of 10 to 100 mu m. The elastic layer is a foamed urethane foam of the dry process, has a resilient 2.5 ~ 4.5mm thickness and is a polyurethane with a sense of elasticity formed large pores large cell size 250 ~ 400㎛. The cover layer is a polyurethane sheet which is a polyurethane having a thickness of 0.3 to 1.5 mm in the form of a sheet which prevents hand contamination and does not slip on the palm. The following hardness means "asker F hardness" of the whole applicator, and is an applicator as hardness measured by an ASKER (manufacturer) DUROMETER HARDNESS measuring instrument (Type F). Means the hardness before the composition is absorbed.

	Comparative Example 1	Example 1
Coating layer	Polyurethane	Polyurethane
Impermeable layer	-	Polyurethane
Elastic layer	Polyurethane	Polyurethane
Cover layer	Polyurethane	Polyurethane
Hardness	56	58
Foundation Absorption	9.7 g	4.3 g
Content delivery rate	27.6%	40.2%

As shown in Table 2, the absorption rate of the applicator including the non-transmissive layer was low, it was confirmed that the contents are not absorbed in the elastic layer.

Experimental Example 2 Non-Transmissive Layer Thickness Design Experiment

The effect on the thickness of the non-transmissive layer was tested. According to the non-transmissive layer thickness, the cosmetic effect, usability, and workability were evaluated. The results are shown in Table 3.

The following Examples 2 to 5 and Comparative Example 2 are the same applicator as Example 1 except for the thickness of the non-transmissive layer.

	Example 2	Example 3	Example 4	Example 5	Comparative Example 2
Coating layer thickness	Polyurethane1.0mm	Polyurethane1.0mm	Polyurethane1.0mm	Polyurethane1.0mm	Polyurethane1.0mm
Impermeable layer thickness	Polyurethane0.01mm	Polyurethane 1mm	Polyurethane 2mm	Polyurethane 3mm	Polyurethane 4mm
Elastic layer thickness	Polyurethane4.0mm	Polyurethane4.0mm	Polyurethane4.0mm	Polyurethane4.0mm	Polyurethane4.0mm
Cover layer thickness	Polyurethane1.0mm	Polyurethane1.0mm	Polyurethane1.0mm	Polyurethane1.0mm	Polyurethane1.0mm
Hardness	67	68	70	70	69
Makeup effect	Soft and fit	Soft and fit	Soft and fit	Soft and fit	Poor adhesion
Feeling	Soft	Soft	Soft	Soft	Stiffness
Machinability	Good	Good	Good	Good	Degradability

As a result, as shown in Table 3, when the non-transmissive layer exceeds 3.0 mm, workability is poor, and the joining surface of the edge of the applicator is weak. In addition, the applicator is stiff, the adhesion on the skin is lowered and the makeup effect is reduced. Therefore, it was found that the thickness of the non-transmissive layer is preferably 0.01 to 3.0 mm.

 Applicator including a non-transmissive layer having a thickness of 0.01 to 3.0mm as in the above embodiment can ensure durability from the contents. The non-transparent layer is not wetted because the contents are not absorbed into the applicator, thereby maintaining the elasticity and comfort of the applicator. Moreover, the amount of content delivery to the skin of the applicator is improved.
