We will review in succession the non-porous and then the porous beads. Table 1 and Table 2 show the leading products in the market, which are classified according to their porosity and particle size. By controlling the process and the cross-linking polymerisation, various derivatives can be obtained: different sizes, variable porosity, optical properties, etc. Our review focuses on polymers based on methyl methacrylate monomer which has a spherical shape. A composite material including silica will also be discussed. New technologies have been developed to achieve very innovative products, with versatile properties and applications. Solid polymers such as PMMA (polymethyl methacrylate) were introduced into cosmetic products more than 20 years ago.

This article will look at acrylic polymers and copolymers in both liquid and powder form, focusing on these texturing agents as beads, thickeners, film-formers, associative polymers and more. For many years, the cosmetic industry has been looking for revolutionary products to offer innovative concepts to its consumers.Ĭosmetic ingredients such as acrylate polymers and copolymers help to create various formulas with different visual and sensory effects (mattifying, soft, ball-bearing, velvet feelings, etc.).
