The present invention relates to a liquid drop releasing cosmetic material and more particularly, to a liquid drop releasing cosmetic material which has an excellent visual effect and feeling of use by releasing liquid drop due to rubbing during use and fundamentally solves side effect and antipathy of users due to silicone polymer because it is free from a silicone polymer, and has excellent stability in a cosmetic material of a drop releasing structure.
The contents described below merely provide background information related to the present invention and do not constitute the prior art.
Recently, a liquid drop releasing cosmetic material such as a water drop releasing cosmetic material has been preferred. The water releasing cosmetic material is a cosmetic material that bursts out water by rubbing during the use, and has a unique visual effect to the user and can have an excellent feeling for the user such as moistness and coolness, etc.
The water releasing structure component of the water releasing cosmetic material is highly stable in the cosmetic material, and since the water should be released well at rubbing, silicone polymers are mostly used as the structure of the water releasing component in the water releasing cosmetic material.
However, the silicone component used in the cosmetic material has been variously reported to be harmful to human body such as CMR (Carcinogenic, Mutagenic, Reprotoxic) and as a result, the use of cosmetics is limited starting in Europe.
Accordingly, it is urgently required to develop a cosmetic material having a water releasing effect without using a silicone component.
The object of the present invention is to provide a liquid drop releasing cosmetic material and more particularly, to a liquid drop releasing cosmetic material which has an excellent visual effect and feeling of use by releasing liquid drop due to rubbing during use and fundamentally solves side effect and antipathy of users due to silicone polymer because it is free from a silicone polymer and has excellent stability in a cosmetic material of a drop releasing structure.

The card house structure of the (a) may comprise 5 to 20 parts by weight of a plate-shaped substance; 40 to 60 parts by weight of oil; and 30 to 50 parts by weight of an emulsifier.
The size of the card house structure having liquid drop in the space therein may be 10 to 60 μm in diameter.
The card house structure having a space formed with a plate-shaped substance therein of the (a) may be in an amount of 0.5 to 20% by weight of cosmetic composition.
Preferably, the liquid drop is water.
A liquid drop releasing cosmetic material according to the present invention has an excellent visual effect and feeling of use by releasing liquid drop due to rubbing during use and fundamentally solves side effect and antipathy of users due to silicone polymer because it is free from a silicone polymer and has excellent stability in a cosmetic material of a drop releasing structure.
Hereinafter, examples of the present invention will be described in detail so as to carrying out easily for those skilled in the art to which the present invention pertains, with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by similar reference numerals throughout the specification.
Throughout the specification, when some parts “comprise” a component, it means that it can include other components as well, without excluding other components unless specifically stated otherwise.
The drop (specifically, water) releasing cosmetic material may have a form which the structure receives water to the inside thereof as shown in
A cosmetic material of present invention is liquid drop releasing cosmetic material by rubbing characterized in that it comprises: (a) a card house structure 110 having a space formed with a plate-shaped substance 130 therein; and (b) liquid drop 120 contained in the space of the card house structure 110.
The drop releasing component 100 of the present invention has the card house structure as shown in
Preferably, the card house structure 110 of the present invention further comprises: at least one oil selected from the group consisting of coco-caprylate/caprate, caprylic/capric triglyceride, dicaprylyl carbonate, myristyl myristate, dicaprylyl ether, cetyl palmitate, octyldodecanol, hexyldecanol, hexyldecyl stearate, cetyl palmitate, isostearyl isostearate, decyl oleate, hydrogenated vegetable oil, methylheptyl isostearate, nigella sativa seed oil, camellia oleifera seed oil and passiflora incarnata oil; and at least one emulsifier selected from the group consisting of polyglyceryl-4 isostearate (HLB 5), polyglyceryl-3 polyricinoleate (HLB 4), polyglyceryl-3 diisostearate (HLB 5.5), polyglyceryl-4 oleate (HLB 3), polyglyceryl-4 diisostearate/polyhydroxystearate/sebacate (HLB 5), diisostearoyl polyglyceryl-3 dimer dilinoleate (HLB 5), polyglyceryl-3 polyricinoleate (and) sorbitan isostearate (HLB 4.2), glyceryl laurate (HLB 5.2), sorbitan oleate (HLB 4.3) and sorbitan sesquioleate (HLB 3.7). Specifically, the card house structure 110 comprises 5 to 20 parts by weight of a plate-shaped substance; 40 to 60 parts by weight of oil; and 30 to 50 parts by weight of an emulsifier. In this case, the liquid drop 120 is easily released by the rubbing during the use of the cosmetic material, the feeling of use is more excellent and the stability of the liquid drop releasing component 100 in the cosmetic material is more excellent.
In addition, the size of the liquid drop releasing component 100 in the cosmetic material of the present invention may be 10 to 60 μm in diameter, preferably 20 to 45 μm, more preferably 20 to 45 μm in diameter of at least 50%. In this case, the liquid drop 120 is easily released by rubbing during the use of the cosmetic material, and the stability of the liquid drop releasing component 100 in the cosmetic material is more excellent. If the size of the liquid drop releasing component 100 is too small, the liquid drop 120 may not be easily released and if the size of the liquid drop releasing component 100 is too large, the stability in the cosmetic material may be significantly reduced.
In the cosmetic material of the present invention, the liquid drop 120 may be in the form of a liquid, and specifically water, but is not limited thereto. The water may be water in which known components that can be used in cosmetic material is dissolved. Specific examples of the known components include ions, flavors, extracts, nutrients, and other functional ingredients used in a cosmetic material, which may be used in an amount of the conventional additives (0.001 to 10% by weight) and in combination with at least two
The liquid drop releasing cosmetic material according to the present invention may be embodied in a variety of formulations capable of releasing the liquid drop 120 comprising a known component. For specific example, the card house structure 110 having a space formed with a plate-shaped substance 130 therein is preferably 0.5 to 20% by weight, more preferably 1 to 10% by weight. When it is used within the above range, the liquid drop 120 is easily released by rubbing during the use of the cosmetic material and the stability of the liquid drop releasing component 100 in the cosmetic material is more excellent.
The liquid drop releasing cosmetic material according to the present invention can be prepared by mixing the material constituting the card house structure 110 with the cosmetic material containing the liquid drop 120. For a specific example, in the case of a cream, it may be prepared by mixing 3 to 20 parts by weight of the material constituting the card house structure 110 with 80 to 97 parts by weight of water in which known components used in cosmetic material are dissolved and optionally 1 to 30 parts by weight of a known ingredient that can be used in cosmetic material such as a moisturizer or a softener, etc., but is not limited thereto. In addition, the material constituting the card house structure 110 may be the plate-shaped material 130 only, and preferably the plate-shaped material 130 of 5 to 20 parts by weight; 40 to 60 parts by weight of oil; and 30 to 50 parts by weight of an emulsifier.
