Q1: What is the primary functional role of Dow CAT 1000PA in formulations?
A: Dow CAT 1000PA is a multi-polymer thickening and rheology-modifying system designed to deliver synergistic viscosity enhancement, improved suspension stability, and enhanced film-forming characteristics—particularly in aqueous-based industrial and household cleaning products, coatings, and personal care emulsions.
Q2: How does this thickener perform in high-electrolyte or hard-water environments?
A: The combination of modified cellulose derivatives (CMC, HPMC) and polyethylene oxide (PEO) provides improved tolerance to ionic strength compared to many single-polymer thickeners, supporting consistent viscosity performance in formulations containing surfactants, builders, or water with moderate hardness—though optimal stability is achieved with formulation-specific optimization.
Q3: Is Dow CAT 1000PA compatible with common anionic and nonionic surfactants?
A: Yes—this thickener system demonstrates broad compatibility with widely used anionic (e.g., LAS, AES), nonionic (e.g., alcohol ethoxylates), and amphoteric surfactants. Compatibility should be verified in final formulations due to potential interactions with cationic species or highly associative thickeners.
Q4: What is the recommended method for incorporating Dow CAT 1000PA into aqueous systems?
A: For best dispersion and hydration, gradual addition under moderate shear (e.g., using a high-shear mixer or rotor-stator) is recommended—preferably as a pre-dispersed slurry in glycerin, propylene glycol, or a portion of formulation water—to minimize agglomeration and ensure uniform thickening development.
