Description

DESCRIPTION

WATER IN OIL EMULSION

TECHNICAL FIELD

The present invention relates to a composition in the form of a water-in-oil (W/O) emulsion, more particularly to a cosmetic composition for making up and/or caring for the skin.

BACKGROUND ART

It is known practice, in the cosmetics or dermatological field, to use W/O emulsions. These emulsions which consist of an aqueous phase dispersed in a fatty phase have an external fatty phase, and therefore cosmetic/dermatological products based on the W/O emulsions can provide comfortable feelings.

On the other hand, there have been cosmetic products in which a liquid cosmetic is

impregnated into a carrier such as a sponge (for example, WO 2013/105804 and WO

2013/002523) in a container. A user of the cosmetic product can use a puff, for example, in order to pick up the liquid cosmetic from the carrier. The use of the carrier can make it easier to use the liquid cosmetic.

DISCLOSURE OF INVENTION

However, it may often be difficult to maintain a liquid cosmetic in the carrier. In particular, it may be difficult to maintain a W/O emulsion in the carrier because the outer phase thereof substantially consists of oil which is easy to fluid. If a liquid cosmetic such as a W/O emulsion cannot be maintained in the carrier, the liquid cosmetic may leak from the carrier, and even from the container.

It may be possible to reduce the leakage by thickening the oil of the W/O emulsion. However, if the oil is thickened, the feeling of freshness will be significantly decreased.

An objective of the present invention is to provide a composition in the form of a W/O emulsion, which can be maintained in a carrier such that it causes no leakage of the

composition from the carrier or a container including the carrier, while maintaining good cosmetic properties such as comfortable feeling to the touch, smooth spreadability and natural finish with good coverage of imperfections on the skin.

The above objective can be achieved by a composition in the form of a W/O emulsion, comprising:

(a) an oil in an amount of 30% by weight or less relative to the total weight of the

composition;

(b) water;

the amount of the (e) lipophilic gelling agent is 1.5 parts by weight or more relative to 100 parts by weight of the oil. The term "W/O emulsion" or "water-in-oil emulsion" means any macroscopically homogeneous composition comprising a continuous oil phase and a water phase dispersed in the said oil phase in the form of droplets. The composition according to the present invention can be maintained in a carrier, such as a support sheet which can absorb a liquid, even under harsh conditions such as a hot

environment and undergoing movement, and can exhibit good cosmetic properties such as fresh sensation, smooth spreadability and natural finish with good coverage of imperfections on the skin.

Hereafter, each of the composition according to the present invention will be described in a detailed manner.

[Cosmetic Products]

The composition according to the present invention may preferably be used as a cosmetic composition. In particular, the composition according to the present invention may be intended for application onto the skin, scalp and/or lips, in particular the skin.

The composition according to the present invention may be charged into a carrier, such as a support sheet. The present invention also relates to a product, preferably a cosmetic product comprising a support sheet and the composition according to the present invention. The carrier, such as a support sheet, may be impregnated with the composition according to the present invention.

It is preferable that the support sheet be porous, which is capable of absorb the composition, such as a sponge and a cushion. The support sheet including the composition according to the present invention may be included in a container to be a cosmetic product such as a foundation. A user of the cosmetic product can take the composition according to the present invention from the support sheet with a tool such as a puff. For example, by applying the tool onto the support sheet, with or without pushing the tool to the support sheet, the composition according to the present invention can be transferred to the tool from the support sheet.

Thus, the composition according to the present invention may preferably be in the form of a fluid, such as a liquid at a temperature of from 20 to 40°C, and preferably an ambient temperature, i.e., 25°C. Advantageously, the composition according to the present invention can have a viscosity of from 900 to 1500 mPa s, preferably from 1000 to 1500 mPa s, measured at 25°C with a Rheomat RM180 viscometer equipped with a No. 4 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at a shear rate of 200 rpm.

Such a viscosity is preferable in order for the composition according to the present invention to be maintained in the support sheet, while providing good cosmetic properties such as comfortable feeling to the touch, smooth spreadability and natural finish with good coverage of imperfections on the skin.

In one embodiment, the support sheet comprises foams.

Suitable foams according to the present invention can be of any type, including

advantageously polyester, polyether, polyethylene, polystyrene, polyurethane, polyvinyl chloride foams, acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), natural rubber (NR), ethylene-vinyl acetate (EVA), latex, silicone , styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), nitrile, butyl, neoprene and mixture thereof.

Preferably, the foams include polyester, polyether, polyurethane, acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR) or mixture thereof.

More preferably, the foams include polyurethane/polyester, polyurethane/polyether or acrylonitrile-butadiene rubber (NBR).

Preferably, the foam is hydrophilic. The term "hydrophilic" is understood to mean foam which absorbs water. Preferably, the foam used according to the invention has a water-absorbing power of 0.4 g/cm³ to 3.5 g/cm³. The water-absorbing power corresponds to the maximum amount of water (in grams) which can be absorbed with regard to a volume of dry foam (in cm³); This amount is determined at a temperature of 20°C and at a pressure of 1 atmosphere. This determination is carried out by weighing foam with a predetermined volume before

impregnation, by then immersing the foam in water, the foam thus being saturated with water when removed, and by weighing the impregnated foam.

The foam can be reticulated or not. Preferably, the foam has a reticulated structure. With a reticulated structure of the foam, the impregnation of a cosmetic composition on the foam is more uniform.

The density of the foam, measured at a temperature of 20°C and at a pressure of 1 atmosphere, can especially vary between 0.1 and 10 pcf (pounds per cubic feet), preferably between 1 and 3 pcf, and more preferably between 1 to 2 pcf. In these range of density, the foam is easier to impregnate and to use.

Advantageously, the foam has a number of pores of 10 to 200 pores per inch (ppi), measured at a temperature of 20°C and at a pressure of 1 atmosphere. More advantageously, the foam has a number of pores of 70 to 120 pores per inch (ppi). In this range of number of pores, the foam is more convenient to use and it has a nicer touch feel.

Advantageously, the foam has an Asker hardness of 12 to 75, and preferably of 30 to 50. The Asker hardness is measured after impregnation of the cosmetic composition on the foam. The measurement is carried out with a durometer hardness tester type F, manufactured by ASKER, at a temperature of 20°C and at a pressure of 1 atmosphere. In this range of hardness, the cosmetic composition can be liberated easily from the foam, without flowing.

Advantageously, the foam has an open cell structure. The cosmetic composition can be more easily impregnated therein.

In addition, this foam can have any size and any shape appropriate for the desired purpose. It can, for example, be rectangular, round, square or oval in shape.

The foam may be flocked, for example with cotton fibers, silk fibers or polyamide fibers. In one embodiment, the support sheet comprises fibers.

The support sheet may comprise at least one woven or non-woven fabric sheet. Typically, the material of the support sheet may be a woven or non-woven fabric made of natural fibers such as cotton, pulp, bamboo and cellulose fibers, semi-natural fibers such as viscose rayon fibers, or synthetic fibers such as polyolefin fibers, polyester fibers and polyamide fibers. Two or more selected from the above fibers may be used in combination.

The term "non-woven" means that individual fibers or threads forming the sheet are arranged in a disorganized manner in a web type structure, and which are not woven or knitted.

The cosmetic composition can be applied on the skin by hand or with a cosmetic tool, such as a NBR puff, for example. The cosmetic product which comprises a support sheet including the composition according to the present invention can maintain the composition in the support sheet for a long period of time even under harsh conditions such as a hot environment and undergoing movement.

Therefore, the discharging of the composition according to the present invention from the support sheet is stable over time. Furthermore, the amount of the composition according to the present invention which can be taken from the support sheet can also be stable over time.

The cosmetic product may be a skin makeup composition, for instance a foundation, a concealer product, a tinted cream, a body makeup composition, and in particular a foundation to be applied to the face and/or the neck.

EXAMPLES

The present invention will be described in a more detailed manner by way of examples.

However, these examples should not be construed as limiting the scope of the present invention. The examples below are presented as non-limiting illustrations in the field of the invention.

Example 1 to 3 and Comparative Examples 1 to 2 [Preparations]

The following compositions according to Examples (Ex.) 1 to 3 and Comparative Examples (Comp. Ex.) 1 to 2, shown in Table 1, were prepared by mixing the components shown in Table 1. The numerical values for the amounts of the components shown in Table 1 are all based on "% by weight" as active raw materials.

Table 1

[Evaluations] (Leakage)

Each (13.5g) of the compositions according to Examples 1-3 and Comparative Examples 1-2 was impregnated into 3 cylindrical porous cushions with the same size, and the cushions were charged into three cylindrical containers. The container was placed in a box such that one was in an upright position, another was in an upside-down position, and the other was in a sideways position. The box was stored in a chamber in which the temperature was 40°C for 24 hours. Just after removing the box from the chamber, the box was subjected to vibration (frequency: 3-5 Hz, vertical acceleration: 0.5-lg, amplitude: 25mm) for 30 minutes in the horizontal direction which is perpendicular to two of the four sides of the box, and for 30 minutes in the horizontal direction which is perpendicular to the other two of the four sides of the box. After the vibration test, the leakage of the composition from the container was visually evaluated in accordance with the following criteria: Good; No leakage and Poor; Leakage was observed. (Texture)

250 mg of each, as a sample, of Examples 1-3 and Comparative Examples 1-2 was applied onto the skin, and spread with the fingers to form a cosmetic film. Fresh sensation, spreadability and thick makeup finish were evaluated by panelists as follows.

Fresh Sensation: Good; Fresh, Poor; Not Fresh

Spreadability: Good; Easy to Spread, Poor; Difficult to Spread

Thick Makeup Finish: Good, Thin Natural Finish; Poor, Thick Unnatural Finish (Viscosity) The viscosity of each of the compositions according to Examples 1-3 and Comparative Examples 1-2 was measured with a a Rheomat RM180 viscometer equipped with a No.3 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at a shear rate of 200 rpm.

The results of the above evaluations are shown in Table 1.

As shown in Table 1 , it is clear that the composition which includes the lipophilic gelling agent can prevent leakage of the composition from the container. Also, the amount of the lipophilic gelling agent relative to the amount of the oil is also important for preventing the leakage. However, in order to realize good cosmetic properties, the amount of the lipophilic gelling agent in the composition should be less than 1.5wt%, preferably 1.3wt% or less and more preferably 1.1 wt% or less, relative to the total weight of the composition. Thus, only the compositions according to the present invention (Ex. 1 to 3) can be maintained in the support sheet such that they cause no leakage of the composition from the support sheet even under harsh conditions such as a hot environment and undergoing movement^ while maintaining good cosmetic properties such as comfortable feeling to the touch, smooth spreadability and natural finish with good coverage of imperfections on the skin.
