Description

Guar Gum, Polymer With Ethanedial CAS NO 68611-04-1 is a chemically modified polysaccharide derived from guar gum, cross-linked with ethanedial (glyoxal) to enhance its performance characteristics. This modification is critical for improving the polymer's stability, viscosity control, and resistance to microbial degradation under demanding conditions. It is an essential material for industries requiring robust, water-soluble thickeners and stabilizers that perform reliably in complex formulations.

Application

• Enhanced Oil Recovery (EOR): Acts as a viscosifier and mobility control agent in polymer flooding operations to improve sweep efficiency.
• Textile Printing & Finishing: Serves as a highly effective thickener for pigment printing pastes, providing sharp print definition and excellent wash-off properties.
• Paper Manufacturing: Used as a dry-strength additive and retention aid to improve paper sheet formation and tensile strength.
• Construction Chemicals: Functions as a water retention agent and workability aid in cement-based products like tile adhesives and grouts.
• Pharmaceuticals: Employed as a binder and sustained-release matrix agent in tablet formulations.
• Personal Care: Provides thickening and stabilizing properties in lotions, creams, and hair care products.
• Water Treatment: Utilized as a flocculant aid to enhance the aggregation and settling of fine particles.

Quality Control

Our Guar Gum, Polymer With Ethanedial is manufactured under a strict quality management system. Each batch is tested to ensure it meets precise specifications for parameters such as degree of substitution, viscosity, and residual cross-linker content. Certificates of Analysis (COA) documenting these results are available upon request. We can supply grades tailored to meet the requirements of various industrial standards.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
