Description

Pemulen TR-2 is a high-performance polymeric emulsifier and rheology modifier, known chemically as a crosslinked polyacrylate. This versatile agent is critical for creating stable, elegant emulsions with a luxurious sensory profile. It is primarily used by formulators in the personal care and cosmetics industry who require excellent thickening and stabilizing properties in surfactant-based systems. Its unique chemistry allows for the development of rich, stable lotions and creams with enhanced consumer appeal.

Application

• Primary emulsifier and stabilizer in oil-in-water (O/W) cosmetic and personal care emulsions.
• Key ingredient for formulating stable, pearlescent, and opaque shower gels and body washes.
• Rheology modifier for creating rich, creamy textures in facial cleansers and moisturizing lotions.
• Stabilizing agent for sun care products, including sunscreens and after-sun lotions.
• Used in the development of high-end skin care serums and creams requiring elegant, non-greasy feel.
• Essential for creating stable, clear gel formulations in hair care products like styling gels.

Quality Control

Our Pemulen TR-2 is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Quality is verified through a series of tests including viscosity, pH, and residual monomer analysis. While not a pharmacopoeial material, production adheres to cGMP principles suitable for cosmetic applications. A Certificate of Analysis (COA) detailing specific batch results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed when not in use to prevent moisture absorption and caking.
