Embodiment 1

[0015] The capsule wall materials include 38 g of K2 carrageenan, 8 g of polyvinyl alcohol, and 1 g of grape skin pigment; the capsule core materials include 16 g of simethicone oil, 3 g of witch hazel extract, and 2 g of calendula flower extract extract and 1 g chamomile extract. Add the capsule wall material to 400 mL of deionized water, and stir evenly at 60°C; heat the capsule core material to 70°C, stir evenly, and homogenize for 3 minutes under a homogenization pressure of 45MPa. The hydrogel microcapsules are prepared by the dropping method, the uniformly stirred capsule wall material solution flows out from the dripper, and the homogeneous capsule core material flows out from the dripper to form a sandwich liquid column, and then the liquid is cut off with a cutter column, forming a series of droplets with a diameter of 1 mm and a diameter ratio of capsule core to capsule wall of 1:6 to prepare hydrogel microcapsules.

Abstract

The invention provides a hydrogel microcapsule with pore minimizing efficacy, which is a microcapsule with a core-shell structure. A capsule wall is purple red transparent, and the materials of the capsule wall include a gel material, a water-soluble film-forming material and natural purple red pigment; a capsule core is white opaque, and the materials of the capsule core include a grease material and a pore minimizing ingredient; the pore minimizing ingredient comprises a hamamelis Virginiana extract, marigold extract and chamomile extract, the mass ratio of three which is 3:2:1; and the hydrogel microcapsule is prepared by adopting a dropping method. The hydrogel microcapsule has attractive and unique appearance, and the convergence activity of the complexes can be effectively protected through the embedding of complexes hamamelis Virginiana extract, marigold extract and chamomile extract; through the synergistic combination action of the complexes, the hydrogel microcapsule integrates the efficacies of moisturizing, convergence and pore minimization, the water and grease balance can be realized, and the pore minimizing effect is better.

Description

technical field [0001] The invention belongs to the field of microcapsules, in particular to a hydrogel microcapsule with the effect of refining pores. Background technique [0002] When the old cutin of the skin accumulates too much, it will make the skin thicker and rougher, resulting in an imbalance of water and oil in the skin and promoting enlarged pores. Staying up late, irregular life, changing seasons or aging are all causes of enlarged pores. If the skin is not properly maintained, the skin will become dull and dry due to the inability to absorb moisture smoothly, which will accelerate the stimulation of the skin to secrete oil and pores. It will then become thicker. [0003] The tannins contained in witch hazel can regulate sebum secretion, and have the effect of moisturizing and shrinking pores; calendula has super healing ability, and can treat acne and enlarged pores; chamomile has a strong soothing effect, which has The moisturizing effect can effectively b...
