Description

Foam impregnate cosmetics < RTI ID = 0.0 >

The present invention relates to a foam for supporting a cosmetic composition, and more particularly, to a foam for supporting a cosmetic composition, and more particularly, to a foam for supporting a cosmetic composition, The present invention relates to a foam for supporting a cosmetic composition which releases an appropriate amount of a cosmetic composition when the cosmetic composition is taken, and which maintains excellent durability even after containing the cosmetic composition.

In general, the liquid cosmetic composition is mainly filled in a vacuum container, a pump container, or a glass container, and is circulated and stored.

However, the containers are inconvenient to carry. In recent years, there has been an increasing demand for a liquid cosmetic composition that is convenient to carry, as the necessity of making or modifying the cosmetic composition easily increases.

As a container that can easily carry the liquid cosmetic composition, a fact type container can be considered. In order to contain a liquid cosmetic composition in a fact type container, it is necessary to determine whether the foam of the liquid cosmetic composition is usable in a fact type container, whether the foam can be well filled with the cosmetic composition, And whether or not an appropriate amount is discharged when taking the cosmetic composition from the foam.

In view of this, a need has arisen for the development of a foam capable of supporting a suitable cosmetic composition that can be used in a fact type container, and an ester foam has been developed as a foamed urethane foam.

However, the ester foam has a good strength and oil resistance with the cosmetic composition is very good, but the cushion property, moist heat resistance, and hydrolysis resistance of the cosmetic composition are poor, and flexibility, softness and puffiness are poor.

Therefore, it has been necessary to solve the problem of the ester foam by using a foam to be impregnated with a cosmetic composition.

To solve this problem, an ether foam for supporting a cosmetic composition has been developed. The ether foam is excellent in cushioning property, air permeability, softness, softness, flexibility, moist heat resistance and hydrolysis resistance to cosmetic composition, There was a falling problem.

Korean Patent Laid-Open No. 10-2009-0100643 (disclosed on September 24, 2009)

Accordingly, the present invention has been made in order to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a cosmetic composition which is well filled with a cosmetic composition, The present invention is to provide a foam that can carry homogeneously for a long period of time and which can release a suitable amount of the cosmetic composition when taking the cosmetic composition and maintains excellent durability even after containing the cosmetic composition.

In order to achieve the object of the present invention, an ether-based polyol and an ester-based polyol are mixed and foamed to form a urethane foam, thereby forming a foam-carrying foam.

The present invention provides a cosmetic composition which is excellent in cushioning property, air permeability, softness, softness, flexibility, moist heat resistance and hydrolysis resistance to cosmetic composition, and excellent in strength and oil resistance to cosmetic composition, It can be carried homogeneously for a long period of time. When taking the cosmetic composition, an appropriate amount of cosmetic composition is discharged, and excellent durability can be maintained even after containing the cosmetic composition.

Therefore, when the composition is used as a foam for supporting a cosmetic composition, the liquid cosmetic composition can be easily carried, and therefore, it can be easily creased even when going out.

As used herein, the term "carrier" means that it can carry any substance or component, which may be exemplified by a composition, and may be represented by a foam together.

In this specification, "supporting ability" means the ability to hold and hold any substance or component.

As used herein, "urethane foam" may be referred to as "foam urethane" after solidification of the polyurethane foam.

In the present invention, an ether-based polyol and an ester-based polyol are mixed and foamed to form a urethane foam.

When the ether-based polyol and the ester-based polyol are mixed, the ether-based polyol is preferably 70 to 90 wt%, the ester-based polyol is preferably 10 to 30 wt%, more preferably 80 wt% By weight, and the ester-based polyol is preferably 20% by weight.

When the ether-based polyol is 70 wt% or less, the cushion property, air permeability, puffiness, softness, flexibility, heat resistance, and hydrolysis resistance with respect to the cosmetic composition are inferior. When the ether polyol is 90 wt% or more, oil resistance and strength are lowered.

If the content of the ester-based polyol is less than 10 wt%, the strength of the ester-based polyol is lowered and the oil resistance of the composition is inferior. When the content of the ester-based polyol is more than 30 wt%, the cushion property, the heat and moisture retention property and the hydrolysis resistance of the cosmetic composition are inferior, .

The density of the urethane foam in which the ether-based polyol and the ester-based polyol are mixed and expanded as described above is from 0.05 to 0.2 g / cm ³ (3.12 to 12.48 lb / ft ³ ), specifically 0.1 to 0.18 g / cm ³ Lt; / RTI > When the density of the foamed urethane is less than 0.05 g / cm ³ , the cosmetic composition is discharged too much, which is inconvenient to use. If the density exceeds 0.2 g / cm ³ , filling and discharging of the cosmetic composition may not be performed well.

In the present specification, the density may be a value measured by the ASTM D3574 method.

The viscosity of the present invention is a cosmetic composition composition foam having a viscosity of 1,000 to 5,000 cps or 15,000 to 60,000 cps, which comprises a urethane foam having a hardness of 1 to 100 on the basis of ASKER hardness type F (Type F) Thereby providing a cosmetic composition foam.

Here, the hardness is the hardness before the cosmetic composition is impregnated. The present cosmetic composition foam contains a urethane foam in which at least one of the hardness and the number of pores per one inch (ppi) is controlled according to the viscosity of the cosmetic composition, so that the cosmetic composition can be stably carried, I can do it.

In the present invention, the viscosity can be measured by a viscosity measuring instrument, for example, LVDV II + PRO or RVDV III ULTRA, spindle NO. 63 or spindle NO. 64, speed 5 RPM, or 12 RPM.

In the present invention, when the cosmetic composition has a low viscosity, specifically, when the viscosity of the cosmetic composition is 1,000 to 5,000 cps (centi poise), more specifically 1,500 to 4,000 cps, and more specifically, 2,000 to 3,000 cps, ASKER) Urethane foam having a hardness of 50 to 100, specifically 60 to 90, more specifically 70 to 80 on the basis of F type (Type F) can be used as a carrier. A urethane foam having a hardness of less than 50 may not be able to stably carry the low viscosity cosmetic composition so that the cosmetic composition may be separated or precipitated and a urethane foam having a hardness of more than 100 may be used when a low viscosity cosmetic composition is to be taken, It may not be easily discharged.

In the present invention, when the cosmetic composition has a low viscosity such that the viscosity range is exemplified, the number of pores per inch (ppi) is less than 10 to 90, specifically 20 to 80, more specifically 30 to 70 Can be used as a carrier.

It is difficult to control the flowability of the low viscosity cosmetic composition and it may be difficult to impregnate the low viscosity cosmetic composition in an appropriate amount. Urethane foam having a pore number per one inch of 90 or more may be used as a low viscosity cosmetic composition The cosmetic composition can be precipitated or separated.

In the present invention, the "number of pores" refers to the number of pores per inch of the urethane foam. In the present specification, the number of pores refers to the number of pores on the horizontal and vertical 1-inch lines using WI-QA-14 It may be a figure that is measured and averaged accurately.

In the present invention, when the cosmetic composition has a high viscosity, specifically, when the viscosity of the cosmetic composition is 15,000 to 60,000 cps (centi poise), more specifically 20,000 to 55,000 cps, and more particularly, 30,000 to 50,000 cps, ) Urethane foam having a hardness of from 1 to less than 50, specifically from 5 to less than 45, more specifically from 10 to less than 40, more specifically from 15 to 35 before impregnation based on the hardener F type (Type F) have.

The urethane foam having a hardness of less than 1 may excessively discharge the cosmetic composition when the high viscosity cosmetic composition is taken, and the urethane foam having hardness of 50 or more may not uniformly impregnate the high viscosity cosmetic composition.

In the present invention, when the cosmetic composition has a high viscosity such as the range of the viscosity, the number of pores per inch (ppi) ranges from 90 to 200, specifically from 100 to 190, more specifically from 110 to 180, Can be used as a carrier. Urethane foam having a pore number per one inch of less than 90 may not uniformly impregnate a cosmetic composition having a high viscosity. Urethane foam having a pore number of more than 200 per inch may have low durability and may reduce feeling of use of a cosmetic composition.

In the present invention, the urethane foam is formed by mixing and foaming an ether-based polyol and an ester-based polyol into a urethane foam, which has a larger pore size and a higher air permeability than a single polyester-based urethane foam or polyether-based urethane foam, It has good strength, softness, flexibility and elasticity as well as high strength, excellent oil resistance to cosmetic composition, and particularly excellent durability even after carrying ability and composition.

In the present invention, the cosmetic composition includes an aqueous dispersion type, an oil dispersion type, a water-in-oil (W / O) type or an oil-in-water (O / W) type composition.

In the present invention, the cosmetic composition includes both a cosmetic composition for skin care or a cosmetic composition for make-up, and specifically includes makeup primer, makeup base, foundation, powder, twin cake, lipstick, lip gloss, eye shadow, eyebrow, concealer, Formulation with a makeup primer, makeup base, liquid or solid foundation, powder, twin cake, lipstick, lip gloss, eye shadow, eyebrow, concealer or blusher But is not limited thereto.

In the present invention, when the cosmetic composition is an ultraviolet screening agent, it is possible to make cosmetics having high stability and portability regardless of the viscosity of the ultraviolet screening agent by impregnating the cosmetic composition carrier according to the present invention. In addition, since the ultraviolet ray blocking agent is taken from the carrier and applied to the skin, no separate hand washing is required, so that the ultraviolet ray shielding effect can be easily enjoyed even when going out.
