The specific embodiment
To combine the practical implementation method to specify the present invention below, be used for explaining the present invention in schematic enforcement of the present invention and explanation, but not as to qualification of the present invention.
The invention discloses a kind of powder puff shape convergence type cosmetics, be not interpreted as meaning with the routine that the conventional the knowledgeable of knowledge is arranged in the technical field under the present invention if technical term that below uses and scientific terminology have specified otherwise.In addition, identical with prior art technology formation and effect will not explain over and over again.The present invention is different with the dosage form of existing convergence cosmetics; The white shape convergence cosmetic material and the mixing of low boiling liquid gas that will comprise firming agent are inserted in the container; Can cause to such an extent that rapid decline of peripheral temperature forms the convergence cosmetic material of powder puff shape according to the liquid gas volatilization during use; This cosmetic material is covered in and can reduces temperature moment behind the skin that Yin Gaowen and sweat becomes unable and form nature convergence and pore contractive effect; Thereby make skin recover elastic force, and skin can obtain lasting cooling effect through powder puff shape cosmetic material.
The present invention includes percentage by weight is: 40~60% the white shape cosmetic material and the low boiling liquid gas of surplus; Said white shape cosmetic material comprises following raw materials by weight percent:
(1), emulsion form part: 1.0~10% fatty acid, 0.1~2% surfactant, 1~10% glycerol, 1~10% wetting agent;
(2), additive part: 2~10% ethanol, 10~40% gel;
(3), watery part: 0.01~2% firming agent, 0.01~2.0% pH regulator agent and the pure water of surplus.
Above-mentioned surfactant of the present invention preferably uses anionic surfactant, because anionic surfactant helps forming the full form of powder puff.
In addition, it is 10~20 lower fatty acid that above-mentioned fatty acid preferably uses the backbone c atoms number, because being solidificated in of powder puff 10 can't form when following, surpass 20 and can become too hard again, and 10~20 just in time helps forming the powder puff of optimal hardness.
In addition, thus above-mentioned firming agent can reduce peripheral temperature according to the volatilization of liquid gas rapidly makes liquid convergence cosmetic material solidify to form the powder puff shape.
In the present invention, firming agent preferably uses one or more in cyclodextrin, silicon dioxide, Alumen, the polymeric aluminum chloride combination, because these materials are compositions of cosmetics academia permission, not only harmless also have an ability to cure preferably.
In addition, above-mentioned gel preferably uses generally one or more in the acrylate polymer of knowledge, acrylic acid ester emulsion, the sodium polyacrylate combination altogether.
Also have, above-mentioned wetting agent preferably uses generally one or more in the propylene glycol of knowledge, 1,3 butylene glycol, dipropylene glycol, the ethoxydiglycol combination altogether.
And above-mentioned pH regulator agent preferably uses acidity such as citric acid, sodium citrate, lactic acid, sodium lactate, malic acid, hydroxy acid to receive, because these are compositions of cosmetics academia permission, not only harmless also have an ability to cure preferably.
In addition, from economy and operation property angle, above-mentioned low boiling liquid gas preferably uses liquefied petroleum gas (LPG), dimethyl ether (DME), butane (N-Butane).
The present invention to the use amount of mentioned component for forming the consumption of white shape convergence cosmetic material in the allowed band of knowing altogether in conventional cosmetics manufacturing process.
But the convergence cosmetic material composition that is used for emulsion form of the present invention part, additive part, watery part is not to be limited to above-mentioned material, so long as the cosmetics academia allows to use and the composition that can form white shape convergence cosmetic material all can use.
In addition, should make as follows based on powder puff shape convergence cosmetic material of the present invention:
1) heats after firming agent, glycerol, butanediol are mixed to 80~85 ℃ and process the emulsion form part; Heat behind mix pure water purification, cyclodextrin, citric acid, sodium citrate, the additive to 80~85 ℃ and process watery part;
2) above-mentioned watery part and emulsion form are partly cooled off under 35~45 ℃ of temperature after stirring the formation emulsion under 2500~3500rpm with homogenizer;
3) evenly put into ethanol under 2500~3500rpm, stirring the white shape convergence of formation cosmetic material with acrylate polymer mixing reuse homogenizer after the above-mentioned emulsion.
Then, above-mentioned white shape convergence cosmetic material is dissolved with the low boiling liquid gas and be stored in the aerosol container.When this thing sprayed to the outside under gelation state, the firming agent in the convergence cosmetic material can descend because of the temperature that the volatilization of low boiling liquid gas causes and solidify the convergence cosmetic material was the powder puff shape.
To be example with concrete watery part of the present invention below, specify the constituent of cosmetic material.
At first; Form in the firming agent of above-mentioned watery part; Like 2-HP-(2-hydroxypropyl-β-cyclodextrin) wait firming agent to have annular cyclic structure; Therefore it not only can guarantee space of matrices when polymer cure, can also form the powder puff shape and solidify hardness with ensureing, uses so be fit to very much the present invention.At this moment; Firming agent of the present invention is considered the powder puff form and is solidified hardness; Should in whole convergence cosmetic material constitutes weight, keep 0.1~2%,, thereby and can increase the flowability that curing hardness influences product above 2% if because the effect of less than 0.1% above-mentioned purpose can be very low.
Then, need be controlled at 0.01~2% of whole convergence cosmetic material composition weight, make the pH of astringent lotion keep * *~* * as citric acid, the sodium citrate of pH regulator agent.Viscosifier will be controlled at 0.01~1%; Can be very low because less than 0.01% viscosity increases effect; Thereby but it is greasy or uncomfortable too by force dermal sensation to be arrived above 1% viscosity, and is preferably sodium polyacrylate, DMAA/VP copolymer in order to reach the optimum efficiency materials used.
The concrete emulsion form part of cosmetics constituent of the present invention, surfactant for example, the effect of its performance foam booster when forming the powder puff shape is so preferably use anionic surfactant.For example can use the muddy fatty acid 1~10% that forms agent and hardness formation agent of sodium lauryl sulphate 0.1~2.0% and conduct, muddy formation agent and hardness form agent can use stearic acid, myristic acid, bay tree fat acid etc.In addition, wetting agent and lytic agent preferably adopt glycerol and butanediol each 1~10%.At this moment; If surfactant, fatty acid and wetting agent less than 1% then can't form effect should be arranged; If but surpassed 10%, could increase hardness and reduce mobile, wetting agent and lytic agent that dermal sensation is arrived is greasy thereby surfactant can produce too much foam, fatty acid.
In addition; The gel that forms the additive part uses preferably that to comprise acrylate polymer content be 40~50% series of acrylate emulsion 10~40%; For example can use alkyl acrylate copolymer emulsion (ALKYL ACRYLATE COPOLYMER EMULSION), ammonium acrylate copolymer etc., be beneficial to curing and dissolved another assist in dissolving agent and preferably use ethanol 1~10 weight %.
Each the stage manufacturing approach based on powder puff shape convergence cosmetic material of the present invention that is grouped into by above one-tenth specifies as follows.
At first, the watery part of firming agent, pH regulator agent, surfactant being formed is heated to 80~85 ℃ and is dissolved fully; The emulsion form that will comprise fatty acid and polyhydric alcohol is partly heated to 80~85 ℃ and is dissolved fully.Then, after slowly putting into emulsion form when watery part stirs with homogenizer 2000rpm and partly carrying out emulsifying, carry out formal emulsifying with 2000~2500rpm again.Thereby make the fatty acid deposition cause to form cosmetic material if at this moment throw in the formation that can influence particle too soon.Subsequently, above-mentioned emulsifier is cooled off under 35~45 ℃ temperature, put into evenly then that ethanol mixes with acrylate polymer and with 2,500~3,500rpm stirs again, finally obtain white shape convergence cosmetic material.At this moment, if put into acrylate polymer earlier then acrylate polymer will produce resin with alcohol reaction, and can't form powder puff shape astringent lotion material.So must follow the release sequence of ethanol and acrylate polymer.
Then; The white shape convergence cosmetic material of processing like this 40~60% is put into aerosol container dissolving and gelation in the lump with low boiling liquid gas 40~60%; And this thing outwards injection can form the powder puff shape cosmetic material that comprises astringent lotion, the formation of powder puff at this moment can receive the influence of low boiling liquid gas kind.
Therefore, preferably to use boiling point be-50~0 ℃ low boiling liquid gas in order to form powder puff preferably in the present invention.
Below, will give the account in greater detail according to embodiments of the invention and comparative example.But following embodiment just lifts in order to prove the present invention, is confined to the following example so should not be construed as scope of the present invention.
Below be that part concrete powder puff shape of the present invention is restrained the making ratio formulation Example of cosmetics:
The purpose of present embodiment is: confirm whether convergence cosmetic material constructed in accordance can form white shape convergence cosmetic material, be filled in whether to produce powder puff shape astringent lotion when outwards spray the back in the aerosol container.And present embodiment has adopted perusal and method relatively.
At first, made the astringent lotion constituent with powder puff shape by the structure of table 1 record, its manufacturing approach is following.
The first step: the watery part that firming agent, pH regulator agent, surfactant are formed is heated to 80~85 ℃ and is dissolved fully; The emulsion form that will comprise fatty acid and polyhydric alcohol is partly heated to 80~85 ℃ and is dissolved fully.Second step: slowly put into emulsion form when watery part stirs with homogenizer 2000rpm and partly carry out carrying out formal emulsifying with 2000~2500rpm again after the emulsifying.The 3rd step: above-mentioned emulsifier after cooling under 35~45 ℃ the temperature, is put into evenly that ethanol mixes with acrylate polymer and with 2,500~3,500rpm stirs again, finally obtained white shape and restrained cosmetic material.
According to the result that present embodiment is made, embodiment 1~3 has formed the powder puff shape and has solidified required white shape emulsifier.
And the result of observation comparative example 1~3; Because being 0% fatty acid in causing filling a prescription, emulsifier content do not have emulsifying but deposition in the comparative example 1; Acrylate polymer is too high in the comparative example 2 has destroyed emulsifying on the contrary, and fatty acid too much causes the too high and matter that loses flowability of hardness in the comparative example 3.
