curing has a closed cell structure or a semi-open cell structure. When the polyurethane material has a closed cell structure, the cells in the polyurethane are closed, and thus the foam material is not easily impregnated with the low-viscosity emulsified cosmetic composition. Therefore, a polyurethane material having an open cell structure is preferable.<\/p>\n<p>However, highly opened-cell structure absorbs too much low-viscosity cosmetic and supplies an excessive volume of cosmetic to the skin which is undesired of course. On the other side, three-dimensional net structure peculiar to urethane foam, cannot completely prevent the penetration of cosmetic liquid, even if it is compressed to the maximum (about 90%). During prolonged use, cosmetics will penetrate inside requiring the applicator to be discarded.<\/p>\n<p>Further, when the puff is washed, the water absorbed therein is not easily dried providing a location for mold or bacteria.<\/p>\n<p>when the urethane foam has a closed cell structure, they are not easily impregnated with the low-viscosity emulsified cosmetic

polyurethane material and a polyether type polyurethane material. \u00a0However, polyester-based urethane foam tends to collapse well in a humid environment, and has a small cell structure and low air permeability, so that it has low softness, flexibility, and a cosmetic composition. In particular, it is not suitable for impregnating a liquid cosmetic composition. Further, polyether-based urethane foam has higher cost efficiency as compared to polyester-based urethane foam.<\/p>\n<p>The polyether type polyurethane material has a larger honeycomb structure than the polyester type polyurethane material, and thus has improved air permeability, soft touch, flexibility and elasticity. Generally, polyether-based urethane foam is more resistant against humidity as compared to polyester-based urethane foam, and thus shows low brittleness and high stability even under a high-humidity condition. In other words, the polyurethane material exhibits low elasticity, is uncomfortable to use, and is difficult to control the fluidity of the cosmetic composition.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Polyurethane foam cosmetic sponges, or egg sponges, are ideal for makeup application due to their softness, bounce, and latex-free composition.
