Abstract

The invention discloses a preparation process of cosmetic pigments. Raw materials needed by the cosmetic pigments are prepared, and the raw materials include the following components in parts by weight: 20-40 parts of sericite, 80-100 parts of nanometer titania, 1-5 parts of a stabilizer and 100-300 parts of water. The preparation process comprises the following steps: fully grinding the sericite,wherein the diameter of the sericite is 800 meshes; adding the fully ground sericite powder into a mixed solution A, adding a surfactant, stirring at a temperature of 60-80 DEG C at a high rotating speed of 200-300 revolutions per minute for 30-45 minutes, adding ethylene glycol, a pH regulator, a stabilizer and silica, stirring at a temperature of 80-100 DEG C at a high rotating speed of 200-300revolutions per minute for 30-45 minutes, thereby obtaining a mixed solution B. According to the preparation process disclosed by the invention, the various raw materials are non-toxic materials, harm of toxins to skin of a user is avoided, and the preparation process is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a preparation process of pigments for cosmetics. Background technique [0002] According to the "Regulations on the Labeling of Cosmetics" promulgated by the General Administration of Quality Supervision, Inspection and Quarantine on August 27, 2007, cosmetics refer to any part of the human body that is spread on the surface of the human body by smearing, spraying or other similar methods, such as skin, hair, nails, lips and teeth, etc. , chemical industrial products or fine chemical products for the purpose of cleaning, maintaining, beautifying, modifying and changing appearance, or correcting human body odor and maintaining a good state. Any titanium dioxide has a certain function of absorbing ultraviolet rays, and excellent chemical stability, thermal stability, non-toxicity and other properties. Ultrafine titanium dioxide has a stronger ability to absorb ultraviolet light ...
