Description

Spray mask composition and method for applying the spray mask composition to skin

The present invention relates to a mask composition and a method of applying the mask composition to the skin, and more particularly to a spray mask composition and a method of applying the spray mask composition to the skin.

The traditional mask is made by using a mask paper made of non-woven fabric or water-needle cloth, adsorbing the active ingredients for conditioning the skin or treating skin diseases, and then attaching them to the skin (for example, the skin of the face) through the activity. The component acts on the skin to achieve the effect of conditioning the skin or treating skin diseases. For example, Republic of China Patent No. I259774 discloses a bamboo aloe vera moisturizing skin care mask comprising a bamboo sap, an aloe vera juice and a mask paper. However, the conventional mask will affect its effect due to the application of the mask paper, and the available skin parts will be limited due to the appearance of the mask paper.

Another type of smear mask is a polymer mucilage (such as poly(vinyl alcohol), PVA, algin, gelatin, etc.) containing active ingredients for conditioning the skin or treating skin diseases. The film former is applied to the skin without the use of a mask paper. However, the smear mask is not only time-consuming and inconvenient to use, but also susceptible to contamination by the user's hand.

As can be seen from the above, neither the conventional mask nor the smear mask can meet the needs of the application site and convenience, which is a long-standing problem. Therefore, it would be a great boon for mask users to develop a mask that can be applied to any part of the skin (such as the face, elbows, knees, etc.) and that is both convenient and hygienic.

Accordingly, a first object of the present invention is to provide a spray-type mask composition suitable for application to a skin which is easily applied by spraying to any part, comprising a film-forming component and a skin conditioning or skin treatment The active component of the disease. The film-forming component includes polyvinyl alcohol, polyvinyl pyrrolidone (PVP), ethanol, and water.

Another object of the present invention is to provide a method of applying the above-described sprayed facial mask composition to the skin comprising the steps of atomizing the sprayed facial mask composition into a plurality of droplets and causing the droplets The skin is contacted to form a film on the skin.

The effect of the invention is that the spray mask composition can be applied to any skin part by spraying, and is convenient and hygienic, thereby eliminating the disadvantages of the conventional mask and the applied mask.

The present invention provides a spray-type mask composition comprising a film-forming component and an active ingredient for conditioning the skin or treating a skin condition. The film forming component includes polyvinyl alcohol, polyvinylpyrrolidone, ethanol, and water.

In the film-forming component, when the content of the polymer (polyvinyl alcohol and polyvinylpyrrolidone) is too high, the composition of the sprayed mask is too thick and difficult to atomize; when the content of the polymer is too low, This will cause the spray-type mask composition to be applied to the skin and it is difficult to stay in the site. Preferably, the content of the polyvinyl alcohol is in the range of 18 to 21 wt%, the content of the polyvinylpyrrolidone is in the range of 0.3 to 1.0 wt%, and the content of the ethanol is 100 wt% of the total weight of the film-forming component. The range is 15 to 17 wt%, and the water content ranges from 62 to 66 wt%. More preferably, the total weight of the film-forming component is 100 wt%, the content of polyvinyl alcohol is in the range of 19 to 20 wt%, and the content of polyvinylpyrrolidone is in the range of 0.5 to 1.0 wt%, and the content of ethanol is The range is 15 to 17 wt%, and the water content ranges from 63 to 65 wt%.

Preferably, the film-forming component is contained in an amount ranging from 65 to 80 parts by weight based on 100 parts by weight of the total mass of the spray-type mask composition.

Preferably, the active ingredient may comprise a skin active aid such as a humectant. The active component is, for example but not limited to, propylene glycol, 1,3-butanediol, hyaluronic acid, disodium ethylenediaminetetraacetate, dipotassium glycyrrhizinate, sodium lactate, vitamin B3, or a combination thereof.

Preferably, the polyvinyl alcohol has a weight average molecular weight of from 27,000 to 120,000, and the polyvinylpyrrolidone has a weight average molecular weight of from 27,000 to 120,000.

Preferably, the spray mask composition further comprises an emulsifier. The emulsifier may be, but not limited to, Hco-40 emulsifier (purchased from Jiawei Industrial Co., Ltd.), sodium lauryl sulfate or sodium lauryl ether sulfate.

Preferably, the spray mask composition further comprises a thickener. The thickening agent can be, but not limited to, xanthan gum, carboxymethyl cellulose, lauramide diethanolamine (lauramide DEA) or a combination thereof.

Preferably, the spray mask composition further comprises other auxiliary agents such as perfumes and preservatives. The preservative can be, but is not limited to, a paraben, a Phenonip preservative (purchased from Dingyun Industrial Co., Ltd.) or a combination thereof.

The spray type mask composition of the present invention can be formulated according to a general preparation method, preferably by first mixing the active ingredient with other auxiliary agents, and finally according to a specific ratio [such as active ingredient and other auxiliary agents: film forming components. =1: 2 to 1:4 (weight ratio)] The film-forming component was added. More preferably, the step of mixing the active component with the other auxiliary agents is to separately prepare the active component and the other auxiliary agents into a solution, followed by mixing.

The present invention also provides a method of applying the spray mask composition to the skin, comprising the steps of: atomizing the spray mask composition into a plurality of droplets, and contacting the droplets with the skin to A film is formed on the skin.

The above-described atomization method can be carried out by atomizing the spray mask composition into a generally commercially available sprayer containing a spray head, and then atomizing the spray mask composition into a plurality of mist droplets by pressing the spray head.

The invention is further described in the following examples, but it should be understood that these examples are for illustrative purposes only and are not to be construed as limiting.
