Description

Elastomer bead complexed powder coated with vegetable butter and a method of making the same}

The present invention relates to an elastomeric bead composite powder coated with vegetable butter and a method for preparing the same, and more particularly, by applying a powder such as sericite or titanium dioxide coated with vegetable butter such as cocoa butter or mango butter to the elastomer beads The present invention relates to a composite powder having improved moisturizing property and application property, and a method for producing the same.

From the past to the present, cosmetics have been steadily changing to meet the needs of consumers of the time, and double powder cosmetics have been constantly changing according to the needs of the times. In the past, powders were clearly classified into face powders, powder pacts, and two-way cakes, but in recent years, the development of functional powder cosmetics has increased due to the increasing demand for light, transparent and functional powder cosmetics. The distinction between powder cosmetics is gradually disappearing.

The main component of powder cosmetics is talc, which is a plate-like powder, but recently, as talc containing asbestos is a social problem, cosmetics researchers are making great efforts to develop raw materials that can replace talc. Currently, sericite and other flaky powders are being studied as a substitute for talc, and among organic substances, studies are being conducted to try starch as a substitute for talc.

Sericite (sericite, Sericite) is _{K 2 Al 4 (Si 6 Al} 2) O 20 (OH) 4 or _{K 2 O 3Al 2 O 3 6SiO} 2 It is composed of 2H ₂ O, and belongs to monoclinic system and has white or gray white pearlescent powder. K ₂ O 11.8%, Al ₂ O ₃ Compared to mica (Mica) having a composition of 38.5% by weight, 44.2% SiO ₂ , and 4.5% H ₂ O, sericite has a lower K ₂ O content than Mica and SiO _{2 ,} H ₂ O The content of is slightly higher. In addition, it is a pure form of naturally powdered Mica (Aluminium Potassium Silicate), and the finely ground sericite gives special softness and smooth feeling in dry powder, liquid, cream, etc. Helps circulate blood to feed nutrients to cells.

Sericite has the effect of releasing far-infrared rays, and when applied to cosmetics, it helps to restore damaged skin and promote blood circulation to maintain healthy skin. Sericite has an excellent cleaning and cosmetic effect because it has a surface active effect as well as skin beauty, so that the fine particles of sericite penetrate deep into the skin and are easily combined with waste products.

Sericite particles do not tend to agglomerate and can be used for both press-type powders and loose powders. However, since it has elasticity compared to talc, it is necessary to pay attention to the content adjustment because the powder may be easily separated even under a small impact because it is hardly pressurized when excessively blended in the press-type formulation.

Titanium dioxide (TiO ₂ ) is used as a white pigment such as paints and inks due to its excellent hiding power and whiteness, and in particular, it has different physical properties depending on the particle size, and its use is also different.

For example, titanium dioxide pigments having a size of 0.2 to 0.3 μm may exhibit the maximum scattering ability of visible light, and thus are generally used in white powder cosmetics. There are two manufacturing methods, sulfuric acid method and chlorine method. The chlorine method has mainstream in consideration of less industrial waste, less impurities and higher whiteness of the final product than sulfuric acid method.

Titanium dioxide with a particle size of 0.1 μm or less is called “Ultrafine Titanium Dioxide”, and because of its small particle size, it is less concealable and can provide clarity, and thus is used as a main raw material of sunscreen. This is because the particle size is much smaller than 0.2 ~ 0.3 ㎛ that the maximum visible light scattering ability is less concealable and when dispersed in oil with a suitable amount of dispersant can obtain a clear coating film. Compared with the pigment titanium dioxide, there are more particles per unit weight and the surface area is also large, so that the ultraviolet absorbing ability is increased. Because of these properties, it is widely used as a sunscreen for sunscreen cosmetics in the cosmetic field.

Regarding a method for preparing powders by coating powders such as sericite or titanium dioxide, etc., Korean Patent No. 10-0602731, "Cosmetic Raw Materials with Improved Feeling, Manufacturing Method thereof, and Cosmetics Using the TiO _2" A cosmetic raw material has been described that provides functional properties such as UV blocking effect, whitening effect, etc. of the inorganic powder by coating an inorganic powder such as SiO ₂ or ZnO on the surface of the polymer bead, and improves the usability. / 0159804 in 'cosmetic or pharmaceutical product and application for cosmetic or pharmaceutical powders of beads and method of use' A flexible substrate of a multi-piece integral article is described.

Vegetable butter is a vegetable fat, which is in the form of a solid or semi-solid according to temperature, and is easily pushed even by a small force according to the hardness change with temperature, and is used to improve cosmetic applicability.

Regarding the example of using vegetable butter as a cosmetic raw material, Korean Patent Application No. 10-2007-0034171 'Mascara composition containing vegetable butter' has a mascara composition which is easily spread even with a small force to provide a soft spreadability and a clean application surface. It is described in Korea Patent Application No. 10-2008-62942 'The massage cosmetic composition in the form of candles' in the form of a massage cosmetics in the form of candles using natural vegetable butter of high stability and safety, and at a slightly higher temperature than the skin Massage cosmetic composition in the form of candles for promoting blood circulation by the massage and easy absorption of the components in the vegetable butter is described, Korean Patent Application No. 10-2008-0109032 'eye makeup composition containing fragrant vegetable butter Scented vegetable burr without artificial aroma The eye make-up compositions have been described which improve the acceptability of the flavor by containing.

However, none of the prior art has attempted to improve the moisturizing property and the spreadability of the powder by coating the vegetable butter on the powder and then coating it on the elastomer beads.

Elastomeric beads are spherical powders, have excellent spreadability and spreadability in skin applications, have elasticity and provide a soft feeling in product applications. However, due to the characteristics of the raw material itself, the self-binding force is very strong, so that the powder is not separated from each other, and the properties of being strongly bound together such as a sponge, there is a disadvantage that does not provide a uniform grain feeling when the compound is excessively blended.

In addition, when the elastomeric beads are applied to the raw materials as raw materials, the powder blowing phenomenon is severe, and when applied to press-type products (twin cakes, powder pacts, etc.), the press pressure is not properly received. This is because the elasticity of the raw material itself, even after receiving the property to easily restore to its original shape. Therefore, since the separation phenomenon between powders is very severe even in a small impact product, it is necessary to solve such a problem by treating the particle surface.

In addition, since the elastomer beads have a porous silica structure, the oil and sebum absorption ability is very excellent, and when it is applied to the powder formulation as it is, it absorbs all the sebum naturally occurring in the skin. There is a problem that the skin is easily dried and pulling occurs.

The present invention is to provide a vegetable butter-coated elastomer bead composite powder, characterized in that the powder is coated with vegetable butter, it is coated on the elastomer beads again.

In the present invention, the powder is coated with vegetable butter, characterized in that the powder is cerasite or TiO ₂ , the vegetable butter is cocoa butter or mango butter, and the elastomer beads are spherical silicone (INCI Name: Dimethicone / vinyldimethicone crosspolymer) polymer.

The product was obtained by the same procedure as in Example 2-1, except that the products obtained in Examples 1-2 to 1-8 were coated on the elastomer beads, respectively. Named it.

Experimental Example  1: Confirm coating amount of vegetable butter

In this experimental example, the physical and chemical properties of the vegetable butter were examined by quantifying the organic matter of the eight composite powders obtained in Example 1 and confirming the content of the actually coated vegetable butter.

1) Serisite

As a coating agent, sericite was used instead of talc, which is generally used, because talc has a large proportion in powder cosmetic composition, but human safety was not secured due to asbestos detection in 2009. Sericite was used as a coating mother, and domestic sericite was used in consideration of cost reduction and import substitution effect.

① Cocoa Butter Composite Powder

Increasing the composite powder to 500 ℃ by 10 ℃ per minute, by quantifying the weight change of the sample to be reduced at this time to determine the organic matter content in the composite powder by TG-DSC (Differential Scanning Calorimetry, Model name: STA409PC Luxx) The results are shown in FIGS. 2 and 3.

TG /% of the left coordinate axis of Figures 2 and 3 is set to the initial weight value of 100% and represents the weight change that decreases as the sample temperature rises as a percentage, the right coordinate axis for the endothermic and exothermic reaction of the sample during quantification Enthalpy values are shown through DSC analysis.

From Figure 2 it was confirmed that the coating state of the cocoa butter is good by quantifying 5.99% by weight of the organic matter when 5% by weight of the cocoa butter surface treatment, 11.12% by weight when 9% by weight surface treatment of the cocoa butter is quantified As described above, it was confirmed that all the cocoa butter added was well coated.

2 and 3 is a point that the weight is reduced at a temperature of 200 ℃ or more while maintaining the initial weight up to 200 ℃ in the graph showing the weight change. If the cocoa butter was uncoated and only mixed, a change in weight would have occurred at the temperature near the melting point of the cocoa butter (35-36.5 ° C.), but both samples showed a weight change above 200 ° C. Is to prove that the coating is not merely mixed but is coated, and even when using the coating powder of the present invention in summer and relatively high temperature, there is no problem that the cocoa butter is separated and dissolved separately by the external temperature.

② mango butter composite powder

4 and 5 are graphs quantifying the organic content of the powder coated with 5% by weight and 9% by weight of mango butter in sericite, 5.37% by weight 5% by weight mango, 10.01% by weight 9% by weight coating It was confirmed that the mango butter of the coating, organic matter higher than the target amount was determined as well as cocoa butter.

In Figures 4 and 5, the temperature at which the reduction in weight starts is also confirmed around 200 ° C, which means that the cocoa butter is surface-treated (coated), not simply mixed in sericite, as in the case of the surface-treated with cocoa butter. It is.

2) TiO ₂

TiO ₂ is currently used as a white pigment and UV blocking material, and has a high demand among cosmetic raw materials. This is because, as the demand of the sunscreen cosmetics group has increased rapidly compared with the past, the demand of TiO ₂ has also increased rapidly (in general, classified as ultra-fine particles of 0.1 μm or less). However, as the problem of human hazards to nanopowders is rapidly rising socially, solutions for this are also being explored.

In this experiment, the organic material was quantified after coating the vegetable butter in the same manner as the sericite using TiO ₂ having a rutile type of 0.2 to 0.3 μm as a coating agent.

① Cocoa Butter Composite Powder

6 and 7 show the results of quantifying the organic matter of the composite powder surface treated with 5% by weight of cocoa butter, 9% by weight in TiO ₂ , respectively, 7.44% and 11.29% by weight, respectively. As a result, as in the case of sericite, it was confirmed that all of the vegetable butters surface-treated in TiO ₂ were coated.

As the coating amount of cocoa butter increased, the weight change occurred at around 150 ℃, which is different from that of Sericite at around 200 ℃, but the temperature of 150 ℃ was much higher than room temperature and emulsification temperature range. Therefore, there is no problem in applying it as a cosmetic raw material.

② mango butter composite powder

8 and 9 show the results of quantifying the organic matter of the composite powder surface treated with 5% by weight of mango butter, 9% by weight in TiO ₂ , respectively, 7.60% by weight and 11.71% by weight, respectively.

Although the weight loss was also confirmed at 150 ° C. or higher in this experiment, the temperature was much higher than the temperature required for the production of room temperature and emulsion cosmetics, and it was confirmed that the mango butter was coated, not simply mixed.

Experimental Example  2: Confirmation of Coating Degree and Coating Components

Experimental Example  3: Transdermal  Water evaporation measurement and using it Moisturizing  Confirm

In the case of powder products using the elastomer beads of the prior art, there are many advantages such as soft feeling and elasticity by the elastomer beads, but it has a disadvantage of providing a somewhat dry feeling. In this experiment, the moisturizing power was compared by measuring the transdermal water evaporation amount to determine the difference in the moisturizing power between the elastomer bead powder of the prior art and the vegetable bead coated elastomer bead composite powder according to the present invention.

Transepidermal water loss (TEWL) refers to the amount of water evaporated from the dermal transdermal cells, and has the advantage of reflecting the moisturizing properties of the skin exposed to the outside air.

In this experiment, the instrument of MPA 580 of Courage + Khazaka company (C + K Electronic GmbH, Cologne, Germany) of Germany was used, and it was measured by using a Tewameter (Model: TM300) probe to measure the evaporation of transdermal moisture. The unit of water evaporation amount was described as (g / h / m ² ).

As can be seen from the above, in all experimental groups and subjects, the fact that the plant-applied elastomer bead composite powder of the present invention was superior to the fact that the raw material, that is, the vegetable bead-coated elastomer bead coated powder, was applied.

As a result of confirming the initial value of each subject, the tester A had a relatively dry skin condition compared to the tester B and C, and the water evaporation suppression effect was relatively high.

As a result of confirming the difference in moisturizing power between the applied vegetable butters, the A and C experiments showed better moisturizing effect in the fact that cocoa butter was applied, and the B tester in the fact that mango butter was applied.

B. Fit SBT Series Raw Material Application

This experiment confirmed the difference in moisturizing power at 24 ° C and 33% relative humidity by using a formulation in which the vegetable butter-coated TiO2 coated elastomer powder was applied to the powder pact in the elastomer bead-coated powder. Are listed in Table 17 below.

In this experiment, the surface of the vegetable butter-coated TiO ₂ was applied to the elastomer beads and then applied to the powder pact, and the transdermal moisture evaporation rate was measured. The vegetable-coated butter-coated sample was the same as the experimental result using the vegetable butter + sericite. It was confirmed that there is an excellent effect of inhibiting moisture evaporation.

Particularly, in the case of experimenter B, it was confirmed that water evaporation proceeded more than 2 hours after using the prior art elastomer bead composite powder without surface treatment of vegetable butter.

All three subjects were found to have higher moisturizing power in the fact that mango butter coated powder was applied.

Experiment result

A. Vegetable Butter Surface Treated Composite Powder

TG-DSC analysis was performed to confirm whether the surface of the sericite and TiO ₂ was coated with vegetable butter at a predetermined concentration, and the result was higher than the target concentration in all the experimental groups. Based on this, it can be seen that the organic material is well bonded to the inorganic powder.

As a result of TG-DSC graph analysis, all eight samples in this study were accompanied by exothermic rather than endothermic reaction. The endothermic reaction is accompanied by the first melting of the material having a low melting point in a specific temperature range. In the present invention, all of the present invention is accompanied by an exothermic reaction, so that the surface-treated vegetable butter is coated, not merely mixed with the inorganic powder. have.

B. Elastomer Bead Composite Powder Coated with Vegetable Butter Surface-treated Composite Powder

After the composite powder was surface treated on the elastomeric beads and confirmed by SEM and EDS, it was confirmed that all eight sample groups were normally coated on the elastomeric beads, since TiO ₂ had a relatively small particle size compared to sericite. It was confirmed that the coating more uniformly.

According to the EDS analysis, there was a slight difference in the elemental composition between the surface treatment of sericite and the surface treatment of TiO ₂ . And consistent with the main constituent of sericite.

 C. Transdermal Water Evaporation (TEWL) Measurement

In order to determine the difference in moisturizing power between the existing elastomeric bead coated powder and the elastomeric bead coated powder of the vegetable butter surface treatment of the present invention, the same amount of each raw material was prepared, and the transdermal moisture evaporation was measured, and the surface treatment was applied to the elastomeric beads. As the split powder, sericite and TiO ₂ were used in the same manner as above.

Both the sericite and TiO ₂ applied elastomer bead composites showed high transdermal moisture evaporation suppression effect in the experimental group treated with vegetable butter, and thus it was found that it affects the moisturizing power depending on the coating of vegetable butter.

Compared to the experimental group to which sericite was applied, the experimental group to which TiO ₂ was applied was found to have less transdermal moisture evaporation immediately after the fact application, and thus, it was confirmed that the TiO ₂ raw material itself had some moisturizing power compared to the sericite.
