Sodium 35-Bis (B-Hydroxy Ethoxy Carbonyl)Benzene Sulfonate Of Ethylene Glycol Solution turns up frequently in discussions about chemical innovation and specialty industrial applications. At its core, the product is a specially modified sulfonate with a complex structure built on a benzene ring, further functionalized with sodium and b-hydroxy ethoxy carbonyl groups, and stabilized within ethylene glycol. Chemists have taken a simple aromatic sulfonate and given it a twist, embedding it with additional hydroxy and ethoxy chains that transform its physical, chemical, and solubility characteristics.
Detailed molecular characteristics set this compound apart. Its structure integrates a benzene sulfonate backbone, where each phenyl ring gets bonded to sulfonate and two b-hydroxy ethoxy carbonyl side chains. The sodium ion provides the necessary charge neutrality, while ethylene glycol not only acts as a solvent but also further fine-tunes solubility. The common formula can be expressed as C16H20NaO10S, but the detailed notation will vary based on chain length and specific ethoxy incorporation. Engineers and chemists value such exactness because even tiny changes in molecular formula drive shifts in reactivity, compatibility, and end-use features.
You encounter this material most often in the form of a clear or slightly yellowish liquid solution courtesy of the ethylene glycol base, though powder and flakes are also available for different processes. Specific density for the solution hovers between 1.13 and 1.20 g/cm3 at standard conditions. Solid forms—either obtained by evaporating the solvent or by direct synthesis—display as white to pale off-white crystals or flakes. Powdered and pearl variants exist for precise dosing and ease of transport, with careful control on moisture content to avoid clumping. These material forms matter immensely in factory environments where dosing accuracy, solubility speed, and dust suppression all intersect with the health of the workforce and output quality.
In practical use, the pH sits comfortably within alkaline ranges, typically 7-9 when measured in aqueous solutions. That’s a sweet spot for many industrial surfactant and dispersant formulations. The solubility profile here deserves mention: as a sodium sulfonate, this compound offers rapid dissolution in water, ethylene glycol, and mixtures thereof, allowing flexible adaptation into polymer, textile, or detergent matrices. Melting points fall around 120-145°C depending on hydration and specific formulation, which suits rapid processing but demands respect during storage and blending.
This solution typically falls under HS Code 2904.90 for "Sulfonated, nitrated or nitrosated derivatives of hydrocarbons"—a smart fit given the underlying benzene chemistry and functional group diversity. Keeping track of HS Code accuracy is not just about customs paperwork, but about legal compliance and the right shipping protocols. Manufacturers need to stay sharp, as regulatory authorities across both North America and Asia keep an eye on how sulfonates cross borders and enter industrial supply chains.
Sodium 35-Bis (B-Hydroxy Ethoxy Carbonyl)Benzene Sulfonate Of Ethylene Glycol Solution requires thoughtful handling, especially in concentrated or powdered forms. The safety data sheet for most suppliers lists it as an irritant to eyes and mucous membranes, and gloves plus goggles take priority in any setting outside of closed tanks. Ethylene glycol, the solvent here, brings additional hazards: it absorbs through the skin and creates risk if swallowed or inhaled. While not classified as acutely toxic when used correctly, spills or contact must be washed off quickly, and air-handling systems in manufacturing facilities should be well maintained. Harmful effects often arise from careless exposure or improper storage, leading to skin sensitization or, rarely, chronic low-level symptoms in poorly ventilated workspaces.
One thing I’ve noticed across years of working with specialty chemicals: a material’s reputation in safety comes down to training. This compound doesn’t rank among the top hazardous chemicals, yet even moderate irritants demand respect. Standard chemical storage advice applies—sealed containers, protection from direct sunlight, and keeping acids or strong oxidizers far away. In powder and flake form, minimizing dust makes all the difference for both safety and product life. Storage rooms benefit from regular audit and clearly marked hazard signage to keep new workers alert.
Looking at the roots of what makes up this compound, the starting raw materials include benzene sulfonate derivatives, sodium salts, and high-purity ethylene glycol. The hydroxy ethoxy carbonyl side chains rely on access to ethylene oxide chemistry and a pinch of process savvy, as side-products can creep in if the reaction mix wanders from ideal temperatures. Global supply chains for these precursors remain fairly robust, though rising attention to greener sourcing of ethylene glycol and low-impact sulfonation has started to shift the market. Producers who source raw materials from certified, low-emission processes have a real leg up both in selling to Western buyers and in managing downstream disposal issues.
Given rising focus on green chemistry, waste management has come under more scrutiny for this class of chemical. Effluents rich in sulfonate residues and glycol traces require careful treatment, as local water authorities tighten up on allowable discharge limits. Some manufacturers choose in-house recycling, capturing ethylene glycol for reuse and breaking down sulfonates via oxidation or advanced filtration. Growing up in a region where river pollution made headlines taught me firsthand how even trace chemicals in wash streams become a story for decades. Companies that build effective, simple waste treatment into their operations earn community trust and avoid regulatory headaches.
In the real world, this compound turns up as a dispersant, surfactant, and specialty processing aid. Paint, ink, and textile makers find it valuable because it unlocks uniform dispersion of particles, offering bright, stable colors or coatings that last. In detergents and cleaners, those long hydroxy chains and the ethylene glycol vehicle mean it cuts through greases and fouling agents with steady efficiency. Polymer plants use it as an additive to improve solubility or compatibility between tough-to-mix ingredients, getting better texture control in finished plastics or rubber formulations.
I remember touring a detergent manufacturing plant where this material helped cut the need for multiple blending steps. That played out as real cost savings and less manual handling, not just technical benefit. Product form—liquid, powder, solid—becomes a day-to-day operational question. Liquid forms pump and mix fast but shave shelf life if seals fail. Powders offer storability but ask for careful dust control. Pearls and flakes solve many dosing headaches, because you avoid the “fluffiness” and drift of fine powders, making regular operations smoother for staff.
You see density values ranging from about 1.13 to 1.20 g/cm³ for typical commercial liquid solutions—numbers that matter as soon as metering pumps come into the picture. Specific gravity sits in the 1.10-1.17 range, making it heavier than water but lighter than mineral oils common in larger industrial tanks. Experience shows that accurate calibration of mixing equipment relies on these numbers, especially in automated systems where dosing errors can throw off entire batches. Crystal and pearl forms, once dissolved, deliver the same active ingredient concentrations but require precise volumetric conversions during preparation.
You pick up pretty quick which form of the product works for which industry. Plastics and paint shops lean hard into the powders and flakes, which tuck easily into mixing silos and hold up over months. Liquid concentrates travel best in drums or totes, with heavy-duty seals and secondary containment to head off leaks. In high-purity settings, crystal or pearl forms command attention because contamination stays low and material flows evenly. Watching skilled operators blend these materials, you notice how density, flow, and even the ambient humidity all influence the end result.
From a practical angle, most hazards come down to direct contact or accident. Standard PPE—nitrile gloves, splash-proof goggles, and coveralls—do the job. It takes commitment from managers to keep safety culture high, because one lapse around a drum of concentrate can mean hours cleaning up a splash, not to mention the regulatory headaches after an accident. Sites that run tight chemical handling protocols minimize both human and financial risk. Regular safety drills, clear clean-up procedures, and visible MSDS sheets keep teams ready for anything.
The harmful effects aren’t headline-grabbing like some older industrial toxins, but chronic exposure claims do surface in medical journals, especially when ventilation or hygiene slips. The move toward closed system handling, pre-measured packaging, and rapid-dissolving forms reflect industry lessons hard-won over past decades.
The future calls for safer, smarter alternatives—products that offer equivalent performance without the legacy baggage of glycol-based solvents or sulfonate residues that hang around in wastewater. Research into bio-based alternatives, biodegradable analogs, and precision dosing equipment aims to limit impact at every step: raw material sourcing, industrial use, final cleanup. Smart companies pay attention to new regulations and build partnerships with green technology startups. The best answers come through real-world feedback, pushing producers toward higher purity, lower hazard, and smarter supply chain management without sacrificing the critical performance that Sodium 35-Bis (B-Hydroxy Ethoxy Carbonyl)Benzene Sulfonate Of Ethylene Glycol brings to the table.
