Direct Factory Supply from Qingdao Oubo Chemical | High Molecular Weight Hydrophobically Modified Polymers
Polyacrylamide (PAM, CAS 9003-05-8) is a synthetic, high-molecular-weight resin synthesized through the free-radical polymerization of acrylamide monomers. As a versatile water-soluble polymer, PAM serves as an indispensable functional chemistry across global industrial sectors, including municipal wastewater remediation, mineral processing, enhanced oil recovery (EOR), pulp & paper production, and personal care chemistry.
In modern industrial and cosmetic formulations, Polyacrylamide / C13-14 Isoparaffin / Laureth-7 represents a state-of-the-art inverse emulsion system. Designed as a cold-process synthetic rheology modifier and thickening agent, this pre-neutralized polymer complex allows instant hydration and thickening without requiring thermal energy or alkali neutralization. The hydrophobic continuous phase (C13-14 Isoparaffin) encapsulates the cross-linked polyacrylamide core, while non-ionic surfactants (Laureth-7) facilitate rapid phase inversion upon contact with aqueous solvents.

Unlike conventional dry-powder polyacrylamides that rely entirely on hydrogen bonding and chain entanglement in dilute solutions, the hydrophobic blend of C13-14 Isoparaffin creates a low-viscosity continuous phase. When added into aqueous systems under moderate agitation, the Laureth-7 emulsifier triggers inverse micelles to burst, releasing fully hydrated polymer chains into the solution instantaneously. This drastically reduces operational downtime, eliminates fish-eye agglomerates, and lowers thermal energy overhead in processing plants.
Polyacrylamide / C13-14 Isoparaffin / Laureth-7 serves as an essential emulsi-gelling agent in luxury cosmetic creams, serums, and sunscreens. It enables cold formulation processes, stabilizes high oil-phase ratios (up to 40%) without traditional fatty alcohol surfactants, and delivers an exceptionally velvety, non-sticky sensory skin feel. Its extreme stability in pH ranges from 3.0 to 11.0 makes it ideal for AHA/BHA skin peels and vitamin C formulations.
As a high-performance flocculating agent, polyacrylamide facilitates solid-liquid separation in industrial settling tanks, clarification chambers, and sludge dewatering centrifuges. It rapidly neutralizes surface charges on suspended particulate matter and aggregates micro-flocs into heavy macro-flocs for fast sedimentation in leather, dyeing, municipal sewage, and food processing effluents.
Utilized as retention agents, filter aids, and anionic trash scavengers. Polyacrylamide polymers enhance pulp sheet formation, increase short fiber retention rates, and boost dry/wet mechanical strength. Incorporating modified PAM into white-water circuits minimizes chemical raw material loss while significantly reducing effluent biological oxygen demand (BOD).
High molecular weight polyacrylamides act as rheology modifiers, friction reducers, and shale inhibitors in hydraulic fracturing fluid systems. In polymer flooding (EOR), PAM increases injection water viscosity, improving sweep efficiency across heterogeneous hydrocarbon reservoirs and maintaining wellbore structural integrity.
Crucial for solid-liquid extraction and tailings thickening in coal washing plants and precious metal processing (Gold, Silver, Copper, Lithium). PAM accelerates the settlement of fine mineral slurry, enabling rapid clarification of process water for circuit recycling while ensuring environmental compliance for tailings storage facilities (TSFs).
In sugar refining, anionic polyacrylamide accelerates juice clarification and flotation efficiency, removing impurities without altering sucrose purity. In the textile industry, PAM operates as a high-strength warp sizing agent, fabric finishing agent, and dye-house wastewater flocculant.

The global polyacrylamide industry is undergoing a structural transition toward greener, highly efficient, and micro-pollutant-free catalytic synthesis pathways. Standard legacy methods relying on chemical copper-catalyzed acrylamide hydration are rapidly being superseded by advanced bio-catalytic enzymatic synthesis platforms.
Qingdao Oubo Chemical utilizes proprietary bio-matrix nitrile hydratase enzymes to convert acrylonitrile directly into monomeric acrylamide. This biological pathway operates under ambient temperature and pressure, completely eliminating residual heavy copper catalyst impurities and reducing toxic sub-products. The resulting monomer purity exceeds 99.9%, establishing an optimal foundation for ultra-high molecular weight polymer chains (up to 30 Million Daltons).
Driven by strict environmental and safety frameworks such as REACH (EU) and global personal care compliance standards (INCI), our advanced polymerization lines implement controlled post-polymerization stripping. This guarantees residual free acrylamide (AMD) content below 10 ppm for cosmetics and below 250 ppm for industrial municipal grades, ensuring maximum human health and aquatic safety.
In line with global decarbonization initiatives, Oubo Chemical's R&D department is pioneering the integration of renewable, plant-derived bio-isoparaffins to replace traditional petroleum-derived C13-14 paraffin carriers. This next-generation eco-emulsion profile significantly reduces lifecycle carbon footprint while maintaining identical rheological yield values and phase inversion kinetics.
