Description
Technical Field
The invention relates to the field of cosmetics, in particular to a hydrogel microsphere for cosmetics and a preparation method thereof.
Background
Currently, hydrogel microspheres used in cosmetics are added into transparent or translucent essence or gel to achieve the effects of carrying active ingredients, increasing the appearance, improving the skin feel after use and the like. The small ball can be made into various colors, and the cosmetics added with the small ball have rich and beautiful appearance and are popular with consumers.
The existing hydrogel beads mostly adopt the principle that a sodium alginate aqueous solution immediately forms transparent gel when meeting calcium ions, and the sodium alginate aqueous solution is dripped into a calcium chloride aqueous solution by a dripping method to form gel beads immediately, and then the gel beads are collected. The obvious disadvantage of this technique is that when the pellets are placed in a cosmetic system that does not contain calcium ions, the calcium ions in the pellets diffuse out of the pellets and the pellets disintegrate and dissolve away, which greatly limits the use of these spherical hydrogels.
