【DESCRIPTION】
【Invention Title】
COSMETIC COMPOSITION CARRIER COMPRISING FOAMS
【Technical Field5 】
The present disclosure relates to a cosmetic composition carrier comprising
one or more foam.
【Background Art】
10 A liquid cosmetic composition is commonly provided as stored in a vacuum
container, a pump container or a glass container. However, these containers are
inconvenient to carry. Recently, as the necessity of putting on or adjusting makeup
outdoors increases, there is a need of a liquid cosmetic composition that can be
carried conveniently.
15 A compact-type container may be considered as a container capable of
conveniently carrying a liquid cosmetic composition. In order to hold a liquid
cosmetic composition in the compact-type container, it should be considered whether
container is compatible with the cosmetic composition, whether the cosmetic
composition can be effectively filled in the carrier, whether the carrier can impregnate
20 the cosmetic composition stably for a long time, and whether an adequate amount of
the cosmetic composition can be ejected from the carrier.
The inventors of the present disclosure have found out that a cosmetic
composition carrier comprising one or more foam has superior filling ability,
impregnating ability and discharging ability.

In one general aspect, the present disclosure provides a cosmetic
composition carrier comprising one or more foam having 10-130 pores per inch (ppi).
10
【Advantageous Effects】
A cosmetic composition carrier of the present disclosure can effectively fill a
cosmetic composition, impregnate the cosmetic composition stably for a long time,
allows ejection of an adequate amount of the cosmetic composition and maintains
15 superior durability in the state where the cosmetic composition is impregnated.
Accordingly, the cosmetic composition carrier of the present disclosure allows
convenient makeup outdoors since even a liquid cosmetic composition can be carried
conveniently.
20 【Best Mode】
As used herein, a "carrier" refers to a material capable of holding any
substance or component which may be a composition. It can also be expressed as
a "medium". As used herein, "impregnating ability" refers to the ability to hold and
carry any substance or component.
3
As used herein, a "foam" refers to a polymer foamed by dry or wet foaming.
The foam used in the present disclosure has a large pore size, high air
permeability and superior cushioniness, softness, flexibility and elasticity. Further,
the foam of the present disclosure may have superior filling ability of absorbing a
cosmetic composition, excellent impregnating ability of holding the cosmet5 ic
composition stably for a long time, good discharging ability of ejecting an adequate
amount of the cosmetic composition and superior durability even in the state where
the cosmetic composition is impregnated.
As used herein, "hardness measured with an Asker hardness tester type F"
10 refers to the hardness of a foam measured using an Asker Durometer hardness tester
type F before impregnating a composition.
As used herein, "flocking" refers to a process of depositing very short fibers
(flock) onto, e.g., a foam.
In an aspect, the present disclosure provides a cosmetic composition carrier
15 comprising one or more foam having 10-130 pores per inch (ppi). In the present
disclosure, the "number of pores" means the number of pores per inch of a urethane
foam. The number of pores may mean an average number of pores per inch of a
horizontal or vertical line measured according to WI-QA-14 (ASTM).
If the number of pores of the foam is smaller than 10 ppi, impregnating ability
20 may be unsatisfactory. And, if it exceeds 130 ppi, filling ability and discharging
ability may be unsatisfactory. In this regard, the foam of the present disclosure may
have 40-170 ppi, 50-160 ppi, 60-150 ppi, 70-140 ppi or 60-130 ppi, specifically 60-90
ppi.
More specifically, the foam having a number of pores of 10-130 ppi has a
25 hardness measured with an Asker hardness tester type F of 10-100. If the foam has
4
a hardness lower than 10, a content may not be impregnated uniformly and the
cosmetic composition may be ejected excessively. And, if the hardness is greater
than 100, it is difficult to fill and eject the cosmetic composition. In this regard, the
foam may have a hardness measured with an Asker hardness tester type F of 20-90,
30-80, 40-70 or 50-5 60.
In the cosmetic composition carrier according to the present disclosure, the
foam may have a number of pores of 60-90 ppi and the carrier may be for
impregnating a cosmetic composition having a viscosity of 15000-30000 centipoise
(cps).
10 For impregnating a cosmetic composition having a viscosity of 15000-30000
cps, it is desired that the foam has a number of pores of 60-90 ppi. A foam having
the above-described number of pores has superior ability of filling and discharging the
cosmetic composition and also has very superior impregnating ability. More
specifically, the foam has more superior impregnating ability, filling ability and
15 discharging ability for a cosmetic composition having a viscosity of 15000-30000 cps
when the foam has a density of 1.2-2.2 lb/ft3, a hardness measured with an Asker
hardness tester type F of 70-90 and a cell size of 100-400 μm.
In the cosmetic composition carrier according to the present disclosure, the
foam may have a number of pores of 10-30 ppi and the carrier may be for
20 impregnating a cosmetic composition having a viscosity of 60000-100000 cps. For
example, the cosmetic composition may be a cake-type cosmetic composition or a
solid cosmetic composition. For impregnating a cosmetic composition having a
viscosity of 60000-100000 cps, it is desired that the foam has a number of pores of
10-30 ppi. A foam having the above-described number of pores has superior ability
25 of impregnating and discharging the cosmetic composition. More specifically, the
5
foam has more superior impregnating ability and filling ability for a cosmetic
composition having a viscosity of 60000-100000 cps when the foam has a density of
1.7-2.0 lb/ft3, a hardness measured with an Asker hardness tester type F of 10-30
and a cell size of 100-400 μm.
In the cosmetic composition carrier according to the present disclosure, 5 re, the
foam may have a number of pores of 30-60 ppi and the carrier may be for
impregnating a cosmetic composition having a viscosity of 30000-60000 cps.
For impregnating a cosmetic composition having a viscosity of 30000-60000
cps, it is desired that the foam has a number of pores of 30-60 ppi. A foam having
10 the above-described number of pores has superior filling ability, impregnating ability
and discharging ability. More specifically, the foam has more superior impregnating
ability, filling ability and discharging ability for a cosmetic composition having a
viscosity of 30000-60000 cps when the foam has a density of 1.7-2.1 lb/ft3, a
hardness measured with an Asker hardness tester type F of 30-60 and a cell size of
15 100-400 μm.
In the cosmetic composition carrier according to the present disclosure, the
foam may have a number of pores of 90-130 ppi and the carrier may be for
impregnating a cosmetic composition having a viscosity of 1000-5000 cps.
Specifically, the cosmetic composition may have a viscosity of 1000-5000 cps,
20 2000-5000 cps or 3000-5000 cps.
For impregnating a cosmetic composition having a viscosity of 1000-5000 cps,
it is desired that the foam has a number of pores of 90-130 ppi. A foam having the
above-described number of pores has very superior impregnating ability. More
specifically, the foam has more superior filling ability, impregnating ability and
25 discharging ability for a cosmetic composition having a viscosity of 1000-5000 cps
6
when the foam has a density of 4.0-6.6 lb/ft3, a hardness measured with an Asker
hardness tester type F of 100-120 and a cell size of 100-400 μm.
The density may be measured according to ASTM D3574, but is not limited
thereto. The viscosity may be measured using a viscometer, for example, LVDV
II+PRO or RVDV III ULTRA, spindle No. 63 or spindle No. 64, at 5 rpm or 12 5 rpm, but
is not limited thereto.
In the cosmetic composition carrier according to the present disclosure, the
foam may include one or more selected from a group consisting of butadiene rubber
(BR), styrene-butadiene rubber (SBR), natural rubber (NR), wet urethane, dry
10 urethane, polyether, polyester, polyvinyl chloride, polyethylene, ethylene-vinyl acetate
(EVA), latex, silicone, styrene-isoprene-styrene (SIS),
styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), silicone
elastomer, nitrile rubber, butyl rubber and neoprene.
In the cosmetic composition carrier according to the present disclosure, the
15 foam may have a cell size of 50-2500 μm.
If the pore size is smaller than 50 μm, filling ability and discharging ability are
unsatisfactory. And, if the pore size exceeds 2500 μm, filling ability is good but
impregnating ability and discharging ability are unsatisfactory. In this regard, the
foam may have a cell size of 75-2200 μm, 100-2000 μm, 125-1800 μm, 150-1600 μm,
20 175-1500 μm or 200-1400 μm, specifically, 200-1200 μm. In an exemplary
embodiment of the present disclosure, the "pore size (cell size)" may be measured
using an optical microscope (Nikon Eclipse 80i).
In the cosmetic composition carrier according to the present disclosure, the
foam may have a thickness of 5-30 mm.
25 If the thickness of the foam is smaller than 5 mm, the amount of the cosmetic
7
composition that can be impregnated decreases. And, if the thickness exceeds 30
mm, some of the content may remain without being completely ejected. In this
regard, the foam of the present disclosure may have a thickness of 6-29 mm, 7-28
mm, 8-27 mm, 9-26 mm or 10-25 mm.
In the cosmetic composition carrier according to the present disclosure, 5 re, the
foam may be flocked with cotton, cotton/acryl, cotton/acryl/polyester, cotton/rayon,
acryl, polyamide, nylon, polyester, nylon/polyester or silk.
The symbol "/" represents that two materials are used together. For example,
"cotton/acryl" means that the foam is flocked with a mixture of cotton and acryl. In
10 the present disclosure, the mixing ratio of the two materials may be 0.1-10:1, 1-9:1,
2-8:1 or 3-7:1 based on weight.
In the cosmetic composition carrier according to the present disclosure, the
foam may be flocked with a fiber of 0.6-1.5 Denier x 0.6-1.0 mm. A uniform flocking
can be achieved when the fiber has the above-described diameter and length.
15 Specifically, the foam may be flocked with a fiber of 0.6 Denier x 0.6 mm, 0.8 Denier x
0.8 mm, 1.5 Denier x 0.8 mm, 1 Denier x 1.0 mm, 1.5 Denier x 1.0 mm or 1.0 Denier x
0.8 mm, but is not limited thereto. The "Denier" is a unit of measure for the thickness
of a fiber and is often denoted as d or D. 1 Denier is defined as unit weight of 0.05 g
per standard length of 450 m. That is to say, the denier is calculated by the equation
20 D = (L/W) x (w/l) (L: standard length, W: unit weight, w: fiber weight, l: fiber length).
Accordingly, the denier is larger as the fiber is heavier and thicker and is smaller as
the fiber is lighter and thinner.
In the cosmetic composition carrier according to the present disclosure, the
cosmetic composition may be in liquid or solid state.
25 In the cosmetic composition carrier according to the present disclosure, the
8
cosmetic composition may be solution, emulsion, gel, cream or suspension.
In general, a liquid cosmetic composition is difficult to carry and store than a
solid cosmetic composition. However, if the cosmetic composition carrier according
to the present disclosure is used, even a cosmetic composition in liquid or cream
state can be stored and carried stably and safely. If the cosmetic composition 5 is in
solid state, instant change in physical properties due to heat or external impact can
be reduced by impregnating the solid cosmetic composition in the carrier and an
adequate amount of the content can be ejected from the carrier. In another
exemplary embodiment of the present disclosure, the cosmetic composition may be
10 solution, emulsion or suspension, but is not limited thereto.
The cosmetic composition that can be used for the cosmetic composition
carrier according to the present disclosure may be an emulsion composition,
specifically a water-in-oil (W/O) or oil-in-water (O/W) composition or a dispersion
composition, specifically an oily dispersion or an aqueous dispersion.
15 The cosmetic composition may be formulated as, for example, makeup primer,
makeup base, liquid or solid foundation, concealer, lipstick, lip gloss, powder, lip liner,
eyebrow, eye shadow, blusher, twin cake, sunscreen, lotion, cream, essence, etc.,
but is not limited thereto.
The cosmetic composition carrier according to the present disclosure may be
20 provided as a container for a cosmetic product which includes a lower portion for
accommodating the cosmetic product and an upper portion having a cover and,
optionally, a mirror, which is usually called a compact.
Hereinafter, the present disclosure will be described in detail through
25 examples, comparative examples and test examples. However, the following
9
