近代以来，洋货涌入，与公众卫生息息相关的家化业产品也不断出现在民众视野中。随着卫生产品的出现，近代中国家化业也在外界和内增的需求刺激下，产生发展壮大。民族资产阶级领导的民族家化业在与西方家化业不断竞争中逐步提高自己的水平。与此同时，家化产品进入千家万户，民众卫生观念发生巨大变化。在多重因素的影响下，民国时期的卫生面貌发生了新的变化，成为连接“旧社会”与“新社会”的桥梁。民国时期的家化业的发展也为后来新中国时期家化业的发展奠定了基础。家化业在民国时期（1912-1945年）经历了起步、迅速发展、逐步壮大、艰难发展四个阶段，这四个阶段也与民众卫生习惯的改变相互交织。

Since modern times, foreign goods have been pouring in, among which the household chemical products closely related to public health have also constantly appeared in the public vision. With the emergence of health products, modern China's household chemical industry also developed under the stimulation of external and internal demand. The nationalization led by the national bourgeoisie gradually improves its level in the continuous competition with the Western nationalization. At the same time, household products have entered thousands of households, and people's health concept has changed dramatically. Under the influence of multiple factors, the health situation in the period of the Republic of China entered a new stage of development, becoming a bridge between the "old society" and the "new society". It also laid a foundation for household chemical industry in the new China. During the period of the Republic of China (1912-1945), the household chemical industry experienced three stages: rapid development, mushroom growth and difficult development, which were also mingled with the change of public health habits.
