Overview
Methyl methacrylate crosspolymer is a highly porous, cross-linked polymer derived from methyl methacrylate and glycol dimethacrylate. Its unique porous structure enables it to absorb excess sebum, oils, and moisture, making it an effective ingredient for controlling shine and reducing breakouts in cosmetic formulations. It also functions as a film-forming agent and viscosity builder, improving product texture and performance.

Key Benefits

• Sebum absorption: Porous structure absorbs excess oil, reducing shine and preventing clogged pores.

• Shine control: Leaves a matte finish, ideal for oil‑prone and combination skin.

• Film-forming: Provides a smooth, even film on skin and hair.

• Viscosity enhancement: Increases product consistency and stability.

• Smooth texture: Imparts a silky, powdery feel to formulations.

• Compatibility: Works well with a wide range of cosmetic ingredients.

Applications

• Skin care: Mattifying creams, oil-control lotions, anti-acne treatments, and powder-based products.

• Color cosmetics: Foundations, powders, primers, and concealers – absorbs oil, reduces shine, and improves wear.

• Hair care: Styling products, dry shampoos, and hair powders – absorbs excess oil and adds volume.

• Sunscreens: Enhances spreadability and provides a non-greasy feel.

• Other: Suitable for use in deodorants, antiperspirants, and facial masks.

Recommended Use
Typical usage levels: 1–10% by weight of the formulation, depending on desired oil absorption, texture, and viscosity. Can be incorporated into both anhydrous and aqueous systems.

Handling and Storage

• Store in a cool, dry place, away from direct sunlight and moisture.

• Keep containers tightly sealed to prevent contamination.

• Use appropriate personal protective equipment (gloves, dust mask) when handling.

• Shelf life: typically 24 months under recommended storage conditions.

Quality Assurance
Each batch is tested for particle size distribution, volatile content, and purity to ensure consistent performance.
