In addition, the porous gel-type cosmetic to which the porous fibrous material (B) is added has good formability and can have a predetermined shape according to product design.

The gel referred to here in the present invention refers to the soft solid colloid formed by the pre-gel (A) after the dispersion step, adsorption step and cooling forming step, which still has elasticity after the above cooling forming step, so it can be used In the case of the porous gel-type cosmetic of the present invention, the surface area in contact with human skin can be effectively increased by pressing the porous gel-type cosmetic on the contact surface (for example: human skin).

The sponge structure referred to here in the present invention refers to that the porous fibrous material (B) plays the role of particles, fragments, and other finely divided shapes in the gel due to its own porosity, roughness, and insoluble characteristics in the above-mentioned gel. solid or porous structure to provide massage, physical exfoliation (which can be done by rubbing), and to help release the functional additive (C).

Porous gel type cosmetic composition

Next, the contents of the porous gel-type cosmetic composition of the present invention will be described in detail. The porous gel-type cosmetic composition of the present invention may comprise pre-gel (A), porous fibrous material (B), functional additive (C) and polyol solvent (D), which are described separately below.

Pregel (A)

The aforementioned pregel (A) may have a viscosity of 1×10 ³ to 1×10 ⁶ mPa·s (cP). The pre-gel (A) in the present invention is formed by mixing water and gel material, so the pre-gel (A) is a dispersion solution. Generally speaking, the above-mentioned gel material can be powder. In one embodiment, the above-mentioned gel material may be, for example, polysaccharides, polypeptides, acrylic polymers or any combination thereof, but the present invention is not limited thereto.

In a specific example, the aforementioned polysaccharides may include, but are not limited to, carrageenan, seaweed gum, aiyu, locust bean gum, corn sugar gum, cellulose, or any combination thereof.

In a specific example, the above-mentioned polypeptides may be, for example, collagen, gelatin or any combination thereof.

In a specific example, the above-mentioned acrylic polymer may be, for example, various types of commercially available Carbomer synthetic glues. Specifically, for example, the trade name manufactured by Lubrizol Corporation (Lubrizol Corporation) 934 polymer, 940 polymer, 941 polymer, 980 polymer, 981 polymer, 2984 Polymer, 5984 polymer, Silk 100 Polymer, ETD 2050 Polymers, Ultrez 30 Polymer, Ultrez 10 polymer or any combination of the above, etc.

In one example, based on 100 parts by weight of the pregel (A), the amount of the water used is 80 parts by weight to 99.6 parts by weight, and the amount of the gel material used is 0.4 parts by weight to 20 parts by weight .

If the amount of the gel material in the pre-gel (A) is greater than 20 parts by weight, the gel material is less likely to disperse in water, and thus the gel material is likely to be unevenly distributed, resulting in uneven texture of the gel. In addition, if the amount of gel material used is too much, the viscosity of the pregel (A) will be too high, which is unfavorable for the dispersion of other components of the porous gel cosmetic composition, and the porous gel cosmetic composition formed The formability is poor and the texture is hard. On the other hand, if the amount of the above-mentioned gel material is less than 0.4, it is difficult to form a gel, and the texture of the formed porous gel-type cosmetic is too soft, which also causes the problem of poor formability.

Porous fiber material (B)

The porous fibrous material (B) of the present invention may comprise any fibers that are insoluble, hardly soluble or slightly soluble in water, the aforementioned pregel (A) of the present invention and the polyol solvent (D) described later, the above-mentioned porous fibers The material (B) can be a porous fiber block or a porous fiber powder. In one example, the porous fibrous mass may have a sponge-like structure. In another example, the porous fiber powder may have an average particle diameter of 1 μm to 10000 μm (particle or hole-like fibers) or a length of 1 μm to 10000 μm (sheet-like fibers).

In one embodiment, the above-mentioned porous fibrous material (B) may include plant fibers, animal fibers, synthetic fibers or a combination thereof.

In a specific example, the plant fiber may include but not limited to konjac fiber, loofah fiber, oat husk, orchid stem, bamboo carbon fiber, or a combination thereof.

In a specific example, the aforementioned synthetic fibers may be, for example, nylon, polyurethane, silica gel, polypropylene, polyethylene terephthalate, polyacrylonitrile, polyvinyl chloride, polyvinyl alcohol, or a combination thereof.

In a specific example, the above-mentioned animal fiber may include but not limited to keratin fiber, silk fibroin fiber, chitosan fiber or a combination thereof. Specifically, the above-mentioned animal fibers can be wool, silk or down.

Based on 100 parts by weight of the pregel (A), the amount of the porous fibrous material (B) can be 1 to 100 parts by weight, preferably 1 to 50 parts by weight.

If the usage amount of the above-mentioned porous fibrous material (B) is less than 1 part by weight, the porosity and roughness provided by it are insufficient, so that the porous gel cosmetics obtained cannot provide physical exfoliation, massage and The effect of improving the release efficiency of the functional additive (C) described later. If the amount of the above-mentioned porous fibrous material (B) is more than 100 parts by weight, the formability and elasticity of the formed porous gel-type cosmetics will be poor, which is not conducive to the change of the shape of the porous gel-type cosmetics. In addition, an overly rough surface may irritate the user's skin.

Functional Additives (C)

In one example, the functional additive (C) of the present invention may contain moisturizing agents, surfactants, exfoliating ingredients, essential oils, antibacterial agents, antioxidants, pigments or combinations thereof. However, the examples mentioned here are only for illustration, and those who have ordinary knowledge in the technical field of the present invention should be able to add necessary components according to the required functions.

In a specific example, the aforementioned moisturizing agent may include vitamins, plant extracts, polysaccharides, polyalcohols, or a combination thereof. The above-mentioned vitamins may be, for example, provitamin B5, vitamin E, or a combination thereof. The above-mentioned plant extracts can be, for example, aloe vera extracts, green tea extracts, citrus extracts, or combinations thereof. The aforementioned polysaccharides can be, for example, sodium hyaluronate (or hyaluronic acid), chitosan, water-soluble proteoglycan and β-glucan. The aforementioned polyhydric alcohol can be, for example, glycerin, propylene glycol, 1,3-butanediol, 1,2-pentanediol or any combination thereof.

In a specific example, the above-mentioned surfactant may be, for example, an anionic surfactant, a cationic surfactant, a zwitterionic surfactant or a nonionic surfactant. The surfactant can provide the cleaning function of the porous gel-type cosmetic of the present invention.

In a specific example, the above exfoliating ingredients may include but not limited to fruit acids (eg mandelic acid, citric acid, malic acid), salicylic acid, lactic acid or combinations thereof. Generally speaking, the pH value of the above-mentioned exfoliating ingredients is not less than 3.5. In particular, the exfoliation performed by using the functional additive (C) in the present invention belongs to chemical exfoliation, which uses the above-mentioned exfoliating ingredients to metabolize the old keratin on human skin.

In a specific example, the aforementioned essential oils may include, but are not limited to, lavender essential oil, neroli essential oil, cypress essential oil, sweet orange essential oil, grapefruit essential oil, rosemary essential oil, sage essential oil, thyme essential oil, juniper essential oil or combinations of the above, etc. In particular, the examples given here are not intended to limit the present invention, and any commercially available essential oil can be selected according to the efficacy of the essential oil and the desired function of the porous gel cosmetic of the present invention. The effects may be, for example: soothing nerves, repairing cells, whitening and/or moisturizing, etc.

In a specific example, the above-mentioned antibacterial agent and antioxidant have similar functions, and they are all used to increase the preservation of the porous gel cosmetic of the present invention. In one example, the antibacterial agent can be, for example, erythritol tri- or tetra-fatty acid ester. In another example, the above-mentioned antioxidant may be vitamin E or vitamin C, for example.

The above-mentioned pigments can impart different colors to the porous gel-type cosmetics of the present invention, and can be manufactured into various shapes that meet consumers' preferences in conjunction with the forming steps described later.

Based on 100 parts by weight of the above-mentioned pregel (A), the usage amount of the functional additive (C) is 0.01 to 25 parts by weight. Preferably it can be 6 parts by weight to 25 parts by weight.

If the usage-amount of the said functional additive (C) is less than 0.01 weight part, the usage effect of a porous gel type cosmetic will be poor. If the usage amount of the functional additive (C) is more than 25 parts by weight, the aforementioned gel and porous fibrous material (B) cannot absorb such a large amount of functional additive (C), resulting in waste.

Polyol Solvent (D)

The polyol solvent (D) of the present invention contains propylene glycol, butanediol, pentanediol, glycerol or a combination thereof. The polyol solvent (D) is used to increase the dispersibility of the pre-gel (A) to make the texture of the gel uniform.

Based on 100 parts by weight of the above-mentioned pregel (A), the usage amount of the polyol solvent (D) is 0.1 to 20 parts by weight. Preferably, it can be 1 to 5 parts by weight.

If the amount of the above-mentioned polyol solvent (D) is less than 0.1 part by weight, the dispersibility of the pre-gel (A) will be poor, resulting in uneven texture of the formed gel. If the amount of the above-mentioned polyol solvent (D) used exceeds 10 parts by weight, the pregel (A) will be diluted and the formability of the porous gel-type cosmetic will be affected.

Manufacturing method of porous gel cosmetic

Another aspect of the present invention provides a method for producing a porous gel-type cosmetic. The above-mentioned production method is carried out using the aforementioned porous gel-type cosmetic composition, and its detailed type and usage amount are as described above.

In one embodiment, the above-mentioned manufacturing method firstly performs a dispersion step of the pre-gel (A) and the polyol solvent (D) to form a mixed gel, wherein the temperature of the dispersion step may be 20°C to 35°C. In one example, the method of the present invention further comprises uniformly mixing the gel material with water to form a pre-gel (A) before the step of dispersing. The above-mentioned polyol solvent (D) is used to help the pre-gel (A) disperse. If the polyol solvent (D) is not added, the pre-gel (A) cannot be uniformly mixed with other components added later.

Then, the porous fibrous material (B) is added to the mixed gel, and an adsorption step is performed to form a porous gel semi-finished product, wherein the porous fibrous material (B) is insoluble in the pregel (A) and the polyol solvent (D). The above-mentioned adsorption step can be carried out at a temperature of 40°C to 100°C. In this step, the pregel (A) in the mixed gel will be dissolved by heating, and the porous fibrous material (B) can absorb the dissolved pregel (A) during the process. Therefore, if the temperature of the above-mentioned adsorption step is lower than 40° C., the pregel (A) cannot be completely adsorbed by the porous fibrous material (B). On the contrary, if the above-mentioned second temperature is higher than 100° C., the water in the porous gel semi-finished product will evaporate, thereby affecting the elasticity of the prepared porous gel cosmetic.

The above-mentioned adsorption step can be stirred or not stirred. Preferably, stirring may be performed when the porous fibrous material (B) is a porous fibrous material powder. In one embodiment, the above-mentioned dispersion step and adsorption step can be performed using a conventional stirring device. Specifically, the above-mentioned stirring device may be, for example, a planetary mixer, a blade mixer, a cone mixer or a double-screw mixer, etc., and the present invention is not limited thereto.

In particular, if the above-mentioned dispersing step and adsorption step are carried out simultaneously, the gelation may be too fast, and the adsorption of the pre-gel (A) may be uneven, which in turn may cause the surface of the porous gel-type cosmetics to be formed everywhere. Inconsistent roughness makes it difficult to control production quality.

Next, the porous gel semi-finished product is subjected to a cooling molding step to produce a porous gel type cosmetic. The cooling forming step is to cool the porous gel semi-finished product to a temperature of 4°C to less than 40°C.

The cooling forming step here is not particularly limited, and any known forming method can be used to obtain porous gel-type cosmetics of various predetermined shapes. In one example, when the porous fibrous material (B) is a powder, for example, the porous gel semi-finished product can be poured into a mold of a predetermined shape and left to stand for about 5 to 30 minutes to cool the porous gel semi-finished product And shaping, the porous gel-type cosmetics of predetermined shape can be prepared. In another example, when the porous fibrous material (B) is a block, after the adsorption step, the porous fibrous material with pre-gel (A) and/or functional additives (C) can be directly absorbed After the block is cooled, porous gel-type cosmetics can be prepared.

In one embodiment, the aforementioned functional additive (C) can be added to the mixed gel during the dispersion step. In another embodiment, the functional additive (C) can be added to the porous gel semi-finished product between the adsorption step and the cooling forming step. Further, the functional additive (C) of the present invention can be added at any time before the cooling forming step of the above-mentioned production method, and those with ordinary knowledge in the technical field can rely on the functional additive (C) used. Properties determine the timing of addition, so the scope of the present invention should not be limited to the examples mentioned.

In one embodiment, after the cooling and forming step, a dehydration step can be performed to reduce the volume of the porous gel-type cosmetic of the present invention, which is convenient for product preservation, packaging and delivery. This dehydration step can be, for example, dry dehydration or vacuum dehydration at a temperature not higher than 60°C.

Please refer to FIG. 2 , which is a schematic diagram illustrating a porous gel-type cosmetic according to an embodiment of the present invention.

In one example, as shown in FIG. 2 , the porous gel cosmetic 200 produced by the porous gel cosmetic composition and the method for producing the porous gel cosmetic includes a gel 210, a porous fiber The material 220 and the functional additive 230 , wherein the gel 210 is mainly composed of pre-gel (A), and the porous fiber material 220 has a pore structure 221 . Since the porous fiber material 220 is insoluble during the manufacturing process, a porous structure 221 similar to a sponge can be formed in the gel 210, and the porous structure 221 makes the surface 211 of the gel 210 have a certain roughness. In addition, functional additives can It is accommodated in the hole structure 221 and released by friction with human skin.

In one embodiment, the pH value of the porous gel cosmetic may be 3.5 to 7.0.

Therefore, by virtue of the porosity and roughness provided by the pore structure 221 of the above-mentioned insoluble porous fibrous material 220, the porous gel-type cosmetics of the present invention can provide massage and physical exfoliation functions, and help functional additives 230 release.

It should be added that although Fig. 2 of the present invention is shown with the porous fibrous material 220 of powder, those skilled in the art can understand that a block of porous fibrous material can also be used for pre-gel ( A) Adsorption is performed to obtain the porous gel-type cosmetic of the present invention.
