Description
Technical Field
The application relates to the technical field of cosmetics, in particular to a moisturizing component coated lipophilic dispersion powder, a preparation method and application thereof.
Background
In order to obtain the powder coated with the moisture-retaining component, the moisture-retaining component and the base powder are generally mixed directly by mechanical stirring in the conventional method, i.e., the direct coating method. However, since the base powder has hydrophilicity, when the aqueous solution of the moisturizing component is directly mixed with the base powder, the base powder absorbs moisture to form a wet powder with a local wetting state, and the wet powder forms larger hard particles due to an agglomeration phenomenon, the hard particles can be adsorbed on the inner wall of a pot due to the action of centrifugal force in the powdering process, and the phenomenon of sticking the powder to the pot occurs, and on the other hand, the hard particles are difficult to be crushed in the post-treatment process. Meanwhile, the heat generated by high-speed rotation can lead the moisture in the wetting powder to volatilize rapidly, so that the moisture-preserving component can not be dispersed uniformly in time and is crystallized and separated out. Therefore, the traditional direct coating method has the problems of powder sticking to a pot, large quantity of hard particles, uneven coating of a moisturizing component, difficult production operation and the like.
Disclosure of Invention
Based on this, it is necessary to provide a moisturizing component-coated lipophilic dispersion powder, and a preparation method and application thereof, in view of the above-mentioned problems; the preparation method ensures that the coating utilization rate of the moisturizing component is up to more than 90%, simultaneously solves the problems of powder sticking to a pot, large number of hard particles and the like, ensures that the obtained lipophilic dispersion powder coated by the moisturizing component is firm and uniform in coating, and can be widely applied to cosmetics as a raw material.
A preparation method of a hydrophilic dispersion powder coated with a moisturizing component comprises the following steps:
mixing a volatile organic solvent with an additive to obtain a first phase, and mixing a moisturizing component with water to obtain a second phase, wherein the additive is a polyglycerol ester emulsifier or a mixture of a water-in-oil emulsifier and a coupling agent, and the moisturizing component is solid at 0-30 ℃;
mixing the first phase with the second phase to obtain a composite treating agent, wherein the first phase is an external phase of the composite treating agent, and the second phase is an internal phase of the composite treating agent; and

In the preparation method of the hydrophilic dispersion powder coated with the moisturizing component, on one hand, the composite treating agent obtained by mixing the first phase and the second phase is a stable water-in-oil emulsion, and the moisturizing component can be combined with the hydrophilic group of the additive at the interface because the hydrophilic group and the hydrophobic group are arranged in the additive, and the hydrocarbon chain of the additive forms a polymerization barrier for the energy required by wetting the moisturizing component, and meanwhile, the hydrophobic group of the additive enables the moisturizing component to be stably and uniformly dispersed in the outer phase as the inner phase, so that the moisturizing component and the basic powder are uniformly mixed in the subsequent preparation process.
On the other hand, in the drying process after the uniform mixing of the basic powder and the composite treating agent, the organic solvent and the water gradually volatilize, so that the moisturizing component is recrystallized from the water phase and deposited on the surface of the basic powder, thereby realizing that the moisturizing component is firmly coated on the basic powder, and the coating utilization rate of the moisturizing component is up to more than 90 percent, effectively improving the utilization rate of raw materials and reducing the resource waste.
Therefore, when the basic powder and the composite treating agent are mixed and dried, the moisturizing component is deposited on the surface of the basic powder through recrystallization, and hydrophilic groups of the additive can be adsorbed on the surface of the basic powder under the action of hydrogen bonds, so that the moisturizing component and the additive are firmly and uniformly coated on the surface of the basic powder, meanwhile, hydrophobic interfaces can be formed on the surface of the basic powder by rich hydrophobic groups in the additive, thereby, the basic powder can be prevented from absorbing moisture in the composite treating agent, further, the problems that the basic powder is agglomerated to form hard particles, powder sticking pot occurs in the powder beating process and the like are avoided, and finally, the dispersion powder with firmly coated moisturizing component and hydrophobic and oleophilic is obtained.

Detailed Description
The lipophilic dispersion powder coated with the moisturizing component, the preparation method and the application thereof provided by the application are further described below.
The preparation method of the hydrophilic dispersion powder coated with the moisturizing component provided by the application comprises the following steps:
s1, mixing a volatile organic solvent with an additive to obtain a first phase, and mixing a moisturizing component with water to obtain a second phase, wherein the additive is a polyglycerol ester emulsifier or a mixture of a water-in-oil emulsifier and a coupling agent, and the moisturizing component is solid at 0-30 ℃;
s2, mixing the first phase with the second phase to obtain a composite treating agent, wherein the first phase is an external phase of the composite treating agent, and the second phase is an internal phase of the composite treating agent; and
and S3, mixing and stirring the basic powder and the composite treating agent, and then drying and crushing to obtain the lipophilic dispersion powder coated with the moisturizing component.
In the step S1, when the volatile organic solvent is adopted to prepare the first phase, the viscosity of the composite treating agent can be effectively reduced, so that the internal phase and the external phase in the composite treating agent are more uniformly dispersed, and meanwhile, the base powder is prevented from being adhered to the stirrer in a large area when the composite treating agent and the base powder are mixed and stirred. In addition, the volatile organic solvent with low boiling point is easy to volatilize and has no residue when being dried.
Optionally, the volatile organic solvent comprises at least one of isododecane, dodecane, tridecane, octadecane, isohexadecane, C9-12 alkane, cyclopentadimethicone, and cyclohexasiloxane. In some embodiments, the mass of the additive is 30% -60%, preferably 40% -50% of the mass of the volatile organic solvent.
When the moisture-preserving component is in a liquid state, the phase change does not occur at the drying temperature, so that the moisture-preserving component is combined with the basic powder only by intermolecular force, the coating firmness is poor, and the moisture-preserving component is easy to fall off. Therefore, the application selects the moisture-preserving component which is solid at 0-30 ℃ and is deposited on the surface of the basic powder by recrystallization at the drying temperature, thus realizing the firm coating effect of the moisture-preserving component.
Because the moisturizing component is solid at 0-30 ℃, if the moisturizing component is directly mixed with the additive, the moisturizing component is not completely dissolved, so that the moisturizing component is unevenly coated, and the coating quality of the lipophilic dispersion powder coated by the moisturizing component is poor. Therefore, water is required to be introduced as a medium, so that the solubility of the moisturizing component is increased, and the coating quality of the moisturizing component is improved.
The polyglycerol ester emulsifier can provide abundant hydrophilic groups and hydrophobic groups, and can be used as an emulsifier and a hydrophobic component to provide hydrophobic performance. Therefore, the additive may be a polyglycerol ester-based emulsifier.
Optionally, the polyglycerol ester emulsifier comprises at least one of polyglycerol-10 ester, polyglycerol-8 ester and polyglycerol-6 ester.
When the additive is a polyglycerin ester-based emulsifier, the mass of the emulsifier is preferably 0.5 to 6% of the mass of the base powder, and more preferably 1 to 3% in order to make the aqueous phase emulsifiable and dispersible more uniformly.
The coupling agent can cooperate with the polyglycerol ester emulsifier to realize a more excellent hydrophobic effect, so the additive can be a mixture of the polyglycerol ester emulsifier and the coupling agent.
Optionally, the coupling agent includes at least one of triethoxy octyl silane, aminopropyl triethoxy silane, stearyl triethoxy silane, triethoxy silyl ethyl polydimethylsiloxane/polymethylsiloxane copolymer, triethoxy silyl ethyl polydimethylsiloxane ethyl hexyl polydimethylsiloxane, triethoxy silyl ethyl polydimethylsiloxane, perfluoro octyl triethoxy silane, perfluoro octyl ethyl triethoxy silane, and triisopropoxy titanium stearate.
In addition to the polyglycerin ester type emulsifier, the water-in-oil type emulsifier such as silicone oil type emulsifier and polyether type emulsifier can provide hydrophilic groups and partial hydrophobic groups, and the hydrophobic effect can be further optimized by the synergy of the coupling agent, so that the hydrophilicity and hydrophobicity of the emulsifier itself can be not limited when the coupling agent is adopted in the additive for synergy, as long as the water-in-oil type emulsifier is used, and in this case, the additive is a mixture of the water-in-oil type emulsifier and the coupling agent.
Optionally, the water-in-oil emulsifier comprises at least one of polyglycerol ester type emulsifier, silicone oil type emulsifier and polyether type emulsifier.
In summary, the additive may be selected from polyglycerol ester type emulsifier directly, or may be a mixture of water-in-oil emulsifier and coupling agent. When the additive is a mixture of a water-in-oil emulsifier and a coupling agent, the water-in-oil emulsifier comprises at least one of a polyglycerol ester emulsifier, a silicone oil emulsifier and a polyether emulsifier, and the polyglycerol ester emulsifier has more abundant hydroxyl groups in hydrophilic groups, so that the polyglycerol ester emulsifier can be firmly coated on the surface of the base powder, and a large number of alkyl chains are grafted at the hydrophobic end of the polyglycerol ester emulsifier, so that good hydrophobicity can be provided, and the mixture of the water-in-oil emulsifier and the coupling agent is preferably a mixture of the polyglycerol ester emulsifier and the coupling agent.
When the additive is a mixture of a water-in-oil emulsifier and a coupling agent, the mass of the mixture of the water-in-oil emulsifier and the coupling agent is 0.5% -6%, preferably 1% -3% of the mass of the base powder, wherein the mass of the water-in-oil emulsifier in the mixture of the water-in-oil emulsifier and the coupling agent is 0.5% -10%, preferably 1% -5% of the mass of the coupling agent.
In some embodiments, the moisturizing component includes at least one of fructooligosaccharides, galactooligosaccharides, lactulose, xylooligosaccharides, soy oligosaccharides, maltooligosaccharides, hydrolyzed hyaluronic acid, hydrolyzed sodium hyaluronate, hyaluronic acid, sodium hyaluronate, potassium hyaluronate, sodium hyaluronate cross-linked polymer, acetylated sodium hyaluronate, sorbitol polyether-20, magnesium PCA, aluminum PCA, zinc PCA, copper PCA, manganese PCA, hydroxyethyl urea, sodium polyglutamate. The water is selected from deionized water, fruit water, flower water or pure dew.
In order to coordinate the use amount of the moisturizing component and the water and ensure the proper viscosity of the water phase, the mass of the moisturizing component is 0.1-5% of the mass of the basic powder, preferably 0.5-2%; the mass of the moisturizing component is 5% -200% of the mass of the water.
In the step S2, the composite treating agent obtained by mixing the first phase with the second phase is a stable water-in-oil emulsion, and the hydrophilic group and the hydrophobic group are contained in the additive, so that the moisturizing component can be combined through the hydrophilic group of the additive in the interface layer, and the hydrocarbon chain of the additive forms a polymerization barrier for the energy required by wetting the moisturizing component.
In the step S3, in the drying process after the base powder and the composite treating agent are uniformly mixed, the organic solvent and the water are gradually volatilized, so that the moisturizing component is recrystallized from the water phase and deposited on the surface of the base powder, the moisturizing component is firmly coated on the base powder, the coating utilization rate of the moisturizing component is up to more than 90%, the utilization rate of raw materials is effectively improved, and the resource waste is reduced.
Therefore, when the basic powder and the composite treating agent are mixed and dried, the moisturizing component is deposited on the surface of the basic powder through recrystallization, and hydrophilic groups of the additive can be adsorbed on the surface of the basic powder under the action of hydrogen bonds, so that the moisturizing component and the additive are firmly and uniformly coated on the surface of the basic powder, meanwhile, hydrophobic interfaces can be formed on the surface of the basic powder by rich hydrophobic groups in the additive, thereby avoiding the problems that the basic powder absorbs moisture in the composite treating agent, and further, hard particles are formed by agglomeration of the basic powder, powder sticking is caused in the powder grinding process, and the like.
Specifically, loose small particles are obtained by coating the composite treating agent, the particles can be completely crushed by adopting an air flow crusher and the like, and finally the dispersed powder with uniformly-coated moisture-preserving components, water repellency and oleophylic property is obtained, and the production operation is simple.
Further, when the additive is a polyglycerol ester emulsifier, the polyglycerol ester emulsifier can provide abundant hydrophilic groups and hydrophobic groups; when the additive is a mixture of the water-in-oil emulsifier and the coupling agent, the water-in-oil emulsifier can provide hydrophilic groups and partial hydrophobic groups, and meanwhile, active groups in the coupling agent and active sites on the surface of the basic powder can generate chemical reaction to generate firm Si-O bonds so as to further strengthen the hydrophobic effect. Therefore, the problems of hard particles formed by agglomeration of the basic powder, powder sticking in a powder beating process and the like can be further avoided, and the dispersed powder which is more uniformly coated by the moisturizing component, hydrophobic and oleophylic is obtained.
Especially, when the additive is a mixture of the polyglycerol ester emulsifier and the coupling agent, the polyglycerol ester emulsifier can provide abundant hydrophilic groups and hydrophobic groups, and the synergistic effect of the coupling agent can better avoid the problems that the base powder is agglomerated to form hard particles, the powder sticks to a pot in the powder grinding process and the like, so that the dispersion powder with more uniform coating of the moisturizing component and hydrophobic and oleophylic properties is obtained.
Optionally, the basic powder comprises at least one of titanium dioxide, iron oxide yellow, iron oxide red, iron oxide black, iron oxide brown, chromium oxide green, ultramarine, pearlescence, mica, sericite, mercerized sericite, synthetic fluorophlogopite, boron nitride, talcum powder, calcium carbonate, calcium sulfate hydrate, pearl powder, perlite, magnesium sulfate calcium carbonate, magnesium carbonate, barium sulfate, hydroxyapatite, silica, hydrated silica and kaolin.
Optionally, the temperature of the base powder and the composite treating agent after being mixed and stirred is 80-130 ℃, preferably 105-120 ℃ and the time is 2-5 h, preferably 2-3 h.
The application also provides the lipophilic dispersion powder coated by the moisturizing component, which is prepared by the preparation method, and comprises a base powder, and the moisturizing component and the additive attached to the outer surface of the base powder.
It is understood that when the additive is a polyglycerol ester type emulsifier, the additive attached to the outer surface of the base powder is a polyglycerol ester type emulsifier, and when the additive is a mixture of a water-in-oil type emulsifier and a coupling agent, the additive attached to the outer surface of the base powder is a water-in-oil type emulsifier and a coupling agent.
In one embodiment, the mass of the moisturizing component is 0.5% -2% of the mass of the moisturizing component coated lipophilic dispersion powder, and the mass of the additive is 1% -3% of the mass of the moisturizing component coated lipophilic dispersion powder.
In the lipophilic dispersion powder coated with the moisturizing component, the moisturizing component is firmly and uniformly coated, so that the moisturizing effect is more stable, the hydrophobic and lipophilic effects and the dispersibility are good, and the hydrophilic and lipophilic dispersion powder can be better applied to the fields of cosmetics and the like.
