EU Microplastics Restriction Forces Cosmetic Buyers to Secure Bio-Based Alternatives
Cosmetic procurement teams must source bio-based substitutes ahead of the 2027 EU microplastics ban to avoid supply gaps.
Silica Texturizers
Particle Function
Mineral-based powders modify the tactile properties and light-scattering characteristics of liquid and solid formulations. These silica texturizers consist of porous or non-porous silicon dioxide particles that provide a matte finish and a smooth feel. They are used extensively in cosmetics, coatings, elastomers, and plastics to control gloss and improve handle.
The application is limited by the maximum loading capacity before the material becomes brittle or overly dry.
Formulation Effect
Porosity and surface area determine how the particles interact with oils and other binders. Incorporating silica texturizers into a cream or lotion helps to absorb excess sebum and reduce the appearance of fine lines through optical blurring. In industrial coatings, they provide scratch resistance and prevent surfaces from sticking together.
The size of the particles is carefully controlled to avoid grittiness while maintaining the desired visual effect.
Material Selection
Manufacturers favor these ingredients as inorganic alternatives to synthetic polymer beads. Since silica texturizers are naturally occurring and chemically inert, they do not face the same environmental restrictions as plastic microparticles. Different grades allow for varying degrees of transparency and oil absorption depending on the specific needs of the product.
Pricing depends on the purity of the mineral source and the precision of the milling process.
