Powder Base Materials
These constitute the primary component of pressed powder semi-finished products. Common examples include talc, mica, titanium dioxide, iron oxides, and silica. These materials primarily serve to provide bulk, coverage, and color-rendering capabilities; specifically, mica and silica enhance texture refinement and luminosity, while iron oxides and similar ingredients are responsible for color pigmentation.
Binding System Materials
These are used to bind and structure the powder particles into a solid form. Common ingredients include synthetic esters, silicone oils, plant-based oils, and various waxes (such as beeswax and microcrystalline wax). These materials determine the pressed powder's hardness, compaction density, and the smoothness with which product is picked up by an applicator; they are the critical factors influencing whether the product is prone to crumbling or generating powder fallout.
Functional Auxiliary Materials
These include film-forming agents, antioxidants, preservatives, and fragrances. Some products also incorporate pearlescent pigments or special-effect powders to enhance luminosity or add dimensional depth to the makeup finish. Although used in relatively small quantities, these materials play a vital role in the overall user experience and product stability, enabling the pressed powder semi-finished product to meet the diverse requirements of various cosmetic applications.
