Abstract

The invention provides a preparation method of a color-changeable natural pigment water-based manicure agent, which comprises the following steps: (1) washing carmine radish, cutting into particles, soaking with absolute ethyl alcohol, filtering, soaking residues again, and combining filtrate; (2) performing vacuum concentration on the filtrate; (3) purifying the concentrated solution to obtain an eluent; (4) carrying out vacuum concentration on the eluent, and freeze-drying to obtain carmine radish pigment; (5) adding pectin into the calcium chloride solution, and stirring to obtain colloidal liquid; (6) adding the carmine radish pigment into the colloidal liquid, and stirring to obtain liquid A; (7) uniformly mixing water-based acrylic resin and polyacrylic resin, and adding the mixture into the liquid A to obtain liquid B; and (8) adding neutral aluminum oxide into the liquid B, and stirring. According to the color-changeable natural pigment water-based manicure agent, the high-purity carmine radish pigment is adopted as the coloring agent, and the coloring agent is a natural pigment, is free of toxic and side effects, is good in safety and can present different colors under different pH conditions.

Description

technical field [0001] The invention belongs to the technical field of cosmetic preparations, and in particular relates to a preparation method of a color-changing natural pigment water-based manicure preparation. Background technique [0002] With the continuous improvement of people's living standards, more people not only pay attention to health and environmental protection, but also continue to move towards the direction of makeup fashion. The nail art agents that exist in the market are divided into two categories: solvent-based nail art agents and water-based nail art agents. Solvents commonly used in solvent-based manicure formulations, such as butyl acetate, ethyl ester, and toluene, are mostly volatile and irritating to the human body, affecting human health, and there are also flammable and explosive risks. [0003] The Chinese patent document whose publication date is CN111789779A discloses a high-adhesion water-based nail polish and its preparation method, but i...
