    • It is an object of the present invention to provide a method for producing a hair cosmetic product comprising protein nanoparticles which is obtained by mixing an aqueous medium and an oil medium, wherein the method enables stable emulsification without losing the performance of the protein nanoparticles. The present invention provides a method for producing a hair cosmetic product containing protein nanoparticles which is obtained by mixing an aqueous medium and an oil medium, wherein (a) protein nanoparticles having a mean particle size of 10 to 200 nm are mixed with an aqueous medium having a pH value different from the isoelectric point of the protein at an amount of 0.01% by weight to 5% by weight based on the total weight of the entire solution; and (b) the obtained liquid is mixed with a substance selected from a cationic substance and an anionic substance, which has an electric charge that is on the same side as that of the protein obtained in the step (a).
    • 本发明的目的是提供一种包含通过混合水性介质和油介质获得的蛋白质纳米颗粒的毛发化妆品的制备方法,其中该方法能够稳定地乳化而不损失蛋白质纳米粒子的性能。 本发明提供一种含有蛋白质纳米粒子的毛发化妆品的制造方法,其通过混合水性介质和油介质而得到,其中(a)将平均粒度为10〜200nm的蛋白质纳米粒子与水性介质 基于整个溶液的总重量,其pH值不同于蛋白质的等电点,其量为0.01重量%至5重量%; 和(b)将获得的液体与选自阳离子物质和阴离子物质的物质混合,其具有与步骤(a)中获得的蛋白质相同侧的电荷。
