Embodiment 1

[0016] The capsule wall material includes 38 g of polymethacrylic acid, 8 g of hydroxypropyl methylcellulose, and 2 g of silver glitter powder; the capsule core material includes 16 g of beeswax, 3.5 g of dendrobium extract, 1 g of sage extract, and 0.5 g avocado extract, of which dendrobium extract, sage extract and avocado extract are alcohol extracts. Add 200 mL of deionized water to the capsule wall material, heat and stir at 60°C; heat the capsule core material to 70°C, stir well, and homogenize for 3 minutes under a homogenization pressure of 45 MPa. 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 A series of droplets with a diameter of 8 mm and a diameter ratio of capsule core to capsule wall of 1:4 were formed to prepare hyd...

Embodiment 2

[0019] The capsule wall material includes karaya gum 46 g, chitosan 12 g, and silver glitter powder 4 g; the capsule core material includes sunflower oil 22 g, dendrobium extract 7 g, sage extract 2 g, and avocado 1 g Extracts, of which dendrobium extract, sage extract and avocado extract are alcohol extracts. The capsule wall material can be added to 400 mL of deionized water, heated and stirred at 65°C; the capsule core material can be heated to 75°C, stirred evenly, and homogenized under a homogenization pressure of 55 MPa for 6 minutes. 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 A series of droplets with a diameter of 5 mm and a diameter ratio of capsule core to capsule wall of 1:6 were formed to form hydrogel microcapsules...

Embodiment 3

[0022] The capsule wall material includes 52 g of polymethacrylic acid, 16 g of hydroxypropyl methylcellulose and 6 g of silver glitter powder; the capsule core material includes 26 g of beeswax, 10.5 g of dendrobium extract, 3 g of sage extract and 1.5 g g avocado extract, of which dendrobium extract, sage extract and avocado extract are alcohol extracts. Add 500 mL of deionized water to the capsule wall material, heat and stir at 75°C; heat the capsule core material to 65°C, stir well, and homogenize for 8 minutes under a homogenization pressure of 40 MPa. 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 A series of droplets with a diameter of 3 mm and a diameter ratio of capsule core to capsule wall of 1:5 were formed to prepare ...

Abstract

The invention provides a hydrogel microcapsule with oil-control and acne treatment effects, which is a pearl-shaped microcapsule, wherein the microcapsule wall is slivery and semitransparent and is made from gel materials, a water-soluble film-forming material and slivery glitter powder, the microcapsule core is white and opaque and is made from a grease material and oil-control and acne treatment ingredients which include dendrobe extract, sage extract and avocado extract in a mass ratio of 7:2:1; the hydrogel microcapsule is prepared through a dropping method. The hydrogel microcapsule with oil-control and acne treatment effects disclosed by the invention is beautiful and unique in appearance; the prepared microcapsule is high in embedding rate, so that the dendrobe extract composite is effectively protected; moreover, through the synergistic and cooperative effect of the composite, the water oil of skin is balanced, the sebum cutaneum secretion amount is reduced, the oil-control and acne treatment effects are achieved, the performance is safe, so that the skin is free of a tight and pruritic feeling.

Description

technical field [0001] The invention belongs to the field of microcapsules, and in particular relates to a hydrogel microcapsule with the effect of controlling oil and removing acne. Background technique [0002] Whether it is normal skin, mixed skin or oily skin, it will generally produce oil, especially for individuals with oily skin, often the face will be full of oil within 30 minutes after washing the face, making people look not refreshed, and if Excessive sebum secretion on the skin surface often leads to acne breakouts. Oil control refers to adjusting the amount of oil secreted by the skin. The existing oil control methods include frequent face cleaning, use of oil-absorbing paper, or use of oil-control skin care products. Cleaning the face or using oil-absorbing paper to remove the oil on the facial surface can only achieve short-term The oil control effect is only a physical oil control, and it does not fundamentally solve the problem of oil production and acne....
