(method for preparing)
Next, with the method for explaining preparation cosmetics of the present invention below with more detailed mode based on wet method.
This method for preparing cosmetics of the present invention is used wet method, is used to prepare the for example powder cosmetic composition of the invention described above of cosmetics.Used wet method comprises step: powder is distributed to and obtains slurry in the liquid at least; Through compression or suction with the molding in container of this slurry; Slurry with dry this molding.The details of each step is explained below.
(dispersion steps)
In this step, powder is distributed to and prepares slurry in the liquid at least.This slurry is represented the thick suspension of powder in liquid here.
As stated, this powder comprises at least a non-magnetic pigment as solvent with can comprise at least a magnetic-particle as optional component.This powder preferably comprises at least a above-mentioned specific fillers.This powder can further comprise above-mentioned other component.
Most preferably this powder does not contain magnetic-particle.When magnetic-particle was present in this powder, then the amount of this magnetic-particle was restricted, made when this magnetic-particle is present in the powder cosmetic composition; The ratio of this non-magnetic pigment/this magnetic-particle is 1 or higher, preferred 2 or higher, and more preferably 5 is perhaps higher; More preferably 20 is perhaps higher, and more preferably 30 is perhaps higher, and more preferably 40 is perhaps higher; More preferably 50 or higher and most preferably 100 or higher.
Therefore, this powder can be before the dispersion steps by as preparation down: only mix non-magnetic pigment, perhaps non-magnetic pigment mixed with a small amount of magnetic-particle, make that the ratio of non-magnetic pigment/magnetic-particle is 1 perhaps higher.
Alternately, this powder can be before the dispersion steps as preparation down: the magnetic-particle that comprises at least a portion in the powder of this magnetic-particle with at least a non-magnetic pigment replacement.In this case, preferably, whole magnetic-particles is replaced with non-magnetic pigment.
This liquid typically is solvent, preferred volatile solvent.As volatile solvent, can should be mentioned that water, lower alcohol is ethanol and isopropyl alcohol for example, and ether, fluorohydrocarbon, volatility organosilicon is the cyclic or linear organosilicon of low-molecular-weight and hydrocarbon light liquid isoparaffin for example for example.Aspect availability, preferably isopropyl alcohol and light liquid isoparaffin.Light liquid isoparaffin is most preferred.Above-mentioned volatile solvent can separately or make up and use.
According to the present invention, for example, with said powder weighing, and through any machinery for example the Henschel blender mix.Preferred this mixed-powder can grind through for example hammer mill.
Then, this mixed-powder is weighed, and be distributed to suitable vessel for example the bowl in liquid in.This dispersion steps can be carried out in epicyclic mixer.Disperse not restriction of required time, and can depend on for example mixing arrangement of some factors.For example, if use epicyclic mixer to disperse, can need about 15 minutes-about 20 minutes.
The amount of this powder and liquid is restriction not.The ratio of liquid and amount of powder can decide according to the suitability.If amount of liquid is too high, the slurry that is then obtained can perhaps drip in ensuing forming step in overflow from container, perhaps after final drying steps, can shrink too much.On the other hand, if amount of liquid is low excessively, the slurry that is then obtained is not easy molding in ensuing forming step, perhaps after final drying steps, crackle can take place.For example, this powder and liquid can be with 5:1, preferred 3:1 and more preferably the weight of 2:1 recently use.
Randomly, in this dispersion steps process, can outgas.This degassing can for example be carried out through powder is distributed in the liquid in vacuum chamber.The not restriction of required time that outgases, and can depend on the for example pressure in the vacuum chamber of some factors.For example, the degassing can be carried out about 15 minutes-about 20 minutes.Preferably stir this slurry and come the effectively degassing.
Randomly, the above-mentioned blend step that is used for powder before dispersion steps can merge with this dispersion steps.In other words, this powder can be weighed and directly is distributed in the liquid, need not prior blend step (after it can be grinding steps).
(forming step)
In this step, slurry is carried out molding through compression or suction in container.For example, will pour in the container, and slurry compression and/or suction are produced the shape of slurry through the slurry that dispersion steps obtained of front.
As container, can use any container for example dish or dish.Preferably, can be with dish as container.This container can have aperture, and components of cosmetics can not move through this hole, is used to aspirate out this solvent but solvent can move through this hole.
This slurry is poured into the not restriction of pattern in the container.Typically, two kinds of patterns are arranged here, that is, and top injection and back injection (back injection).
Inject according to this top, slurry is inclined to be poured into the container from container top.The top injection is preferred for preparing the cosmetic product with multiple color.In addition, the injection of this top compares with the back injection that more cost is effective, because container need not be used for the complex mechanism of injecting slurry.
According to this back injection, slurry is gone into the container from the container bottom dump.In order to inject, this container bottom typically must have the mechanism that is used for slurry is supplied to container.This back injection is preferred for the mass preparation cosmetic product.In addition, this back injection can be easy to prepare the cosmetic product with complicated shape.With the slurry that is incorporated in the container is through compression and/or suction molding.Preferably, compression and suction are carried out simultaneously.
This compression can by as get off to carry out: for example have planar compression unit through machinery this slurry be compressed in the container.This suction can for example be carried out with the pressure that reduces in the container through vacuum.This compression and suction can be carried out several.Randomly, can apply vibration to this container and/or compression unit.In preferred this slurry the liquid of at least a portion be through compression and suction remove to solidify this slurry.More preferably most liquid is removed from this slurry.
(drying steps)
In this step, the slurry of dry this molding obtains cosmetics.Through drying, remove the solvent that remains in the slurry fully.Baking temperature depends on the Several Factors for example component of cosmetics and the type of solvent for use.For example, this drying can be carried out at about 60 °-100 °.Dry required time also depends on above-mentioned factor.For example, drying was carried out about 1-6 hour.
Used wet method is favourable in the method for preparing of the present invention, because compare with dry method, it can prepare and comprise a large amount of powder and the cosmetics of a spot of binding agent.In addition, this wet method can easily provide the cosmetics with multiple color or irregularly shaped for example star.
On the other hand, should be noted that so-called half wet process, only use little solvent therein, and do not prepare slurry, this is not equal to wet method.In this half wet process, can not remove and desolvate.In addition, a kind of in addition method wherein prepares slurry, but dry before compression, and dry thing fragmentation is compressed, and also is different from this wet method.
Can have slick texture and good anti-drippage property through the prepared cosmetics of method for preparing of the present invention.In addition, the cosmetics prepared through method for preparing of the present invention can have wetness sensation, good spreadability etc.
Through the prepared cosmetics of method for preparing of the present invention preferably form for example powdery foundation cream, compressing powder and the deodorization powder of powder cosmetic product.Concrete, method for preparing of the present invention can be used for preparing the powder cosmetic of the powdery foundation cream form of moulding powder style such as compacting.
