A good liquid eye shadow needs to use high-quality pigments to effectively ensure that the color of the eye shadow is bright and lasting.
2. Liquid eye shadow preparation process
The preparation process of liquid eye shadow is roughly divided into several steps, including modulating the matrix, adding pigments and adhesives, adjusting the texture, adding surfactants and preservatives, etc.
l Modulating the matrix
First, you need to prepare the formula of the matrix, mix various raw materials in a certain proportion and heat them to make the matrix.
l Add pigments and adhesives
Add the selected high-quality pigments to the matrix, control the amount and uniformity of addition; then add adhesives, mix the pigments and matrix thoroughly, and make the pigment slurry.
