Cosmetic mask

FIELD OF THE INVENTION

The present invention relates to a cosmetic mask composition for topical application which comprises a water-insoluble substrate and a cosmetic composition providing moisturizing benefit to the skin.

BACKGROUD OF THE INVENTION

A sheet which is formed by a substrate sheet such as a non-woven fabric sheet impregnated with a lotion or the like has be used for cosmetic treatments of the skin, in particular the face. Such masks for cosmetic treatment are disclosed, for example in the patent application WO 02/062132, which provides acute skin tone changing benefit to the skin.

Since the mask as such is very wet, it is often difficult to dry out in a relatively short period of time. The consumers may need time to apply the mask on the face in order that the lotion is penetrated into the skin.

On the other hand, EP2489286 disclosed a cosmetic face mask which has perforation-like lines formed in the vertical direction in a trapezoidal area surrounded by lines contecting the bases of the nose wings and bases of the eyes, as well as in a small trapezoidal area formed above this area corresponding to the concave area below the center between the eyebrows. Such a mask can cover the nose wings fully while also covering the area between the eyebrows, while the sheet remains tightly in contact with the skin.

It is also known to use actives in the cosmetic products for treating or caring for the skin, such as moisturizing, whitening, anti-aging, pore minimizing, freshness, smoothness, softness, and so on. Among which, skin conditioning effect such as moisturizing, freshness, smoothness, and softness, is always an interest to consumers around the world. Masks impregnated with lotion containing skin conditioning agents are suitable for applying on the skin for delivering the moisturizing agents.

However, to meet the purpose of cosmetic treatment, it is required to apply the masks of the prior arts to the skin over a lengthy period of time. Consumers found it time consuming to use the masks as such

Based on the foregoing, there is a need for a mask composition which is efficient in delivering the skin conditioning actives to the skin during application. In particular, there exists a need for a mask composition which is not time consuming when applying on the skin, and at the same time, providing good skin conditioning benefit, in particular moisturizing, freshness, smoothness, and softness to the skin.

DETAILED DESCRIPTION OF THE INVENTION

Water insoluble substrate

According to the present invention, the cosmetic mask composition comprises a water insoluble substrate. For the purpose of the invention, the term "water insoluble" means that the substrate is not dissolvable in water, nor does it breaks apart upon immersion in water.

In one embodiment of the present invention, holes, the perforation-like lines or cutting lines are formed at least partially on the substrate. These holes, the perforation-like lines or cutting lines may take any shape that is adaptable to the present invention. For example the holes can be round, oblong, square, and so on. The perforation-like lines or cutting lines can be straight lines, curved lines, slit, lid, and so on.

The holes, perforation-like lines or cutting lines can be formed or positioned on any area on the substrate. In one embodiment, the holes, perforation-like lines or cutting lines are formed on the entire substrate. In another embodiment, they are formed on the substrate area corresponding to the forehead, the cheeks, the nose, the area beside the mouth and below the cheeks, and/or the chin of the face.

Preferably, the holes, perforation-like lines or cutting lines are formed on the entire substrate. There is no limitation of the directions of the perforation-like lines or cutting lines. It can be vertical direction, horizontal direction corresponding to the face, or it can be curved lines which can form concentric circles. In one preferred embodiment, the cutting lines are formed on the substrate area corresponding to the forehead and chin in a horizontal direction corresponding to the face, on the substrate area corresponding to the nose, the area beside the mouth and below the cheeks in a vertical direction, and on the substrate area corresponding to the cheeks forming a concentric circles with curved lines.

According to a preferred embodiment of the present invention, the holes are formed or positioned on the entire substrate. The diameter of the holes or the holes formed by stretching the perforation-like lines or cutting lines is from 1 mm to 15 mm, preferably from 1 mm to 10 mm, more preferably from 1 mm to 5 mm.

The material of the substrate according to the present invention is not limited, and therefore any material can be used for preparing, for example, the substrate shown in Figures 1 and 2. Two or more materials may be used.

Typically, the material 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 and synthetic fibers such as polyester fibers, polyethylene terephthalate fibers, polyethylene fibers, and polypropylene fibers. Two or more selected from the above fibers may be used in combination.

Alternatively, the material may be a film or sheet made from at least one selected from synthetic polymers such as polyethylenes and polyvinylalcohols, semi-synthetic polymers such as bio- celluloses and alginates, and natural polymers such as polysaccharides (e.g., carageenan and xanthan gum), mucopolysaccharides (e.g., hyaluronic acid and sodium hyaluronate), polypeptides (e.g., γ-polyglutamic acid) and proteins (e.g., gelatin and collagen). The film or sheet may be in the form of a gel or a jelly which may be transparent, translucent or opaque. Two or more selected from the above substances may be used in combination.

The folded sheet according to the present invention may be made of two or more layers. Thus, for example, the substrate shown in Figures 1 and 2 may be a layered substrate comprising two or more stacked layers. If a layered substrate is used, the material of each stacked layer may be the same or different from each other. For example, the layered substrate may be prepared by laminating the above film or sheet made from a synthetic polymer, a semi-synthetic polymer and/or a natural polymer on the above woven or non-woven fabric.

The substrate can be made into a wide variety of shapes and forms such as flat pads, thick pads, thin sheets of irregular thickness, depending on the desired use and characteristic of the mask. The substrate is typically designed to fit the area of the skin to which topical application is desired. For example, when the mask is applied to the face, the substrate is designed to correspond to the shape of the face avoiding the eye, nostril, and mouth areas, as necessary. Nonlimiting examples of the substrates useful in the present invention are described, for example, in the patent application WO 02/062132, or EP 2489286A.

Such water-insoluble substrates or masks with holes, perforation-like lines or cutting lines formed whereon can be obtained by cutting desired holes on the conventional masks that are available on the market. Mentions may be made of the suitable commercially available masks such as NA60RP70 from Beijing Dongfang Dayuan Non-wovens Fabric Co., Ltd. Then by using die-cutting machine ZG-10T from Hangzhou Zhiling Co. Ltd for cutting desired holes on the mask, the water-insoluble substrates of the present invention is obtained.
