Description

Technical Field

[0001] The invention relates to a matte baking powder, in particular to a matte baking powder composition that is not easy to change color and a preparation method thereof. Background Art

[0002] Baking powder is generally divided into matte baking powder and pearlescent baking powder. Pearlescent baking powder is made by adding pearlescent powder to baking powder, which makes it have a distinct gloss after application and reflects light under light; while matte baking powder has a soft focus matte matte effect after application. At present, matte baking powder is generally made by mixing water or oil as a solvent with a powder base material for baking. However, the baking method using water easily causes the surface color of matte baking powder to darken. The reason is that the water contains some oil, which makes the color of the matte powder base material darker after absorbing the oil. On this basis, when the mixed material is pressed, part of the water will be sucked out after being squeezed, so that the residual water on the surface will be more than that in the interior. At this time, if the water is forcibly sucked dry, it will cause the powder to crack during the baking process; and when the surface and internal water content of the baking powder are uneven after preparation, most of the oil in the water remaining on the surface of the baking powder will be absorbed by the base material, which will cause the color of the baking powder surface to darken. However, the use of oils such as isododecane for baking can easily cause the matte baking powder to turn white. The reason is that volatile oils such as isododecane evaporate quickly, which can easily bring the lower-density components in the baking powder to the surface, causing the powder to turn white.

[0003] In view of the fact that matte baking powder is easy to change color after baking, there are usually two ways for manufacturers to deal with it. The first is to use fine sandpaper to grind away the discoloration layer on the surface of the baking powder after baking. The second is to spray a coloring layer on the surface of the matte baking powder to cover the discoloration layer on the surface. These two methods increase the processing complexity of matte baking powder on the one hand, and on the other hand, they cannot completely solve the problem of matte baking powder changing color.

[0004] Therefore, a matte baking powder that is not easy to change color is needed. Summary of the invention

[0023] ③ Add product A to product B and mix evenly, then cool to 50°C, add antioxidant, remaining thickener and part of preservatives and mix evenly to obtain product C;

[0024] ④ Take isododecane as product D, mix the filler, colorant, remaining emollient and remaining preservative evenly as product E, add products C and D into product E at a mass ratio of 1:0.95-1.05 and stir until products C, D and E form a plasticine-like state after stirring and fusing, and the mass ratio of the mixture of products C and D to product E is 0.6-0.65:1, to obtain product F;

[0029] Compared with the prior art, the present invention has the following characteristics:

[0030] (1) The present invention forms a composite emulsified system by combining an aqueous solution and an oily solution, so that each baking powder component can form a stable oil-in-water structure during the emulsification process. Therefore, when the mixed solvent evaporates during the preparation of the baking powder, the oil in the aqueous solution remaining on the surface of the baking powder will combine with the powder base material to cause the color of the powder surface to darken. At the same time, the oily solution in the mixed solvent will bring the low-density components in the baking powder to the surface after evaporation, causing the color of the baking powder surface to fade. In addition, by combining the two factors and combining the component restrictions of the aqueous solution and the oily solution, the color of the baking powder surface is kept consistent with that of the interior, which effectively alleviates the color change problem of the baking powder during the preparation process.

[0031] (2) By using triethoxycaprylylsilane or polydimethylsiloxane to treat the pigment surface, the hydrophobicity of the toner can be increased, thereby preventing the toner from precipitating out during the baking process of some organic colorant particles, and further reducing the possibility of discoloration of the baking powder;

[0032] Therefore, the present invention can overcome the problem of surface discoloration of matte baking powder. BRIEF DESCRIPTION OF THE DRAWINGS
