The invention discloses an active particle with barrier repairing effect, comprising grease, an outer layer film wrapped on the outside of the grease, and several liposomes distributed in the grease; the diameter of the active particle is 1 mm to 2 mm; The diameter of the body is 0.8 μm to 1.2 μm; the mass ratio of the outer film, oil and liposome is 5:40:16; the amount of oil used is 8% to 15% of the total weight of the active particles; the oil contains There are vegetable oil and non-vegetable oil, and the amount of vegetable oil is more than 60% of the total weight of oil; the outer layer of the active particles is covered by vegetable polysaccharide gum, which improves the stability of oil, and distributes water in the oil. Liposomes with soluble active substances, when the product with the added particles is in use, the outer film of the particles is broken during application, and the active substance-containing liposomes penetrate into the stratum corneum along with the vegetable oil, releasing anti-inflammatory active substances for a long time. The invention also discloses a preparation process of active particles with barrier repairing effect. |
