ZEODENT 623: Shaping Cleaner, Smoother Toothpaste Formulas

As a chemical manufacturer with decades of silica production experience, we approach every project with a focus on practical impact in real, everyday applications. With ZEODENT 623, our team has channeled years of lab work and customer feedback into a product that addresses common challenges for toothpaste makers and formulators looking for an economical, reliable cleaning silica.

Why ZEODENT 623 is a Staple for Toothpaste Manufacturers

Toothpaste manufacturers want consistent cleaning that supports product claims and satisfies end-users, and ZEODENT 623 steps into that role with proven performance. Its particle morphology and size distribution target gentle removal of stains and debris while keeping dentin and enamel protection front of mind.

Over years of production batches, we have observed how the physical characteristics of ZEODENT 623 support steady paste viscosity and a smooth mouthfeel when properly hydrated and dispersed. Fine-tuning the precipitation and drying process gives us significant control over absorbency, making it easier for our customers to maintain rheology in their paste, even during seasonal raw material changes.

We routinely run batch-to-batch QA checks for loss on drying, pH, heavy metals, and microbiology to ensure that each delivery aligns with cosmetic regulatory limits and internal purity targets. The end result is a silica that supports not only the abrasive function but offers safety and peace of mind to both manufacturer and end-user.

The Physical Structure Behind Performance

Particle shape matters in toothpaste—too jagged, and you risk surface damage; too rounded, and you lose cleaning power. ZEODENT 623’s controlled morphology delivers a balance so teeth get clean without excessive wear. Several of our customers blend it with other ZEODENT grades to hit brand-specific cleaning indices or polish goals. Others use it as their main abrasive because of its consistent, well-documented results.

What adds to its versatility is the tight control of mean particle size and its narrow particle size distribution. Because the granules are well-controlled, formulators get fewer surprises during scaling or product transfers. In side-by-side extruder trials, ZEODENT 623 gives a reliable texture—important for any brand promising a smooth brushing experience each time the tube is opened.

The Value of Controlled Abrasivity

Abrasivity must walk a fine line in today’s toothpaste market. Too harsh, and you risk tooth sensitivity complaints, regulatory scrutiny, and unwanted recalls. Too mild, and toothpaste underperforms, leaving behind stains, which leads to unsatisfied users switching to competitors. ZEODENT 623 is engineered to sit in what many toothpaste experts call the “safe cleaning” zone, where cleaning efficiency meets enamel preservation.

This silica supports a range of total RDA (Relative Dentin Abrasivity) targets, which is crucial for global formulas that need to meet local legislation and consumer expectations. Over multiple real-time shelf life studies, ZEODENT 623 has shown strong stability, maintaining performance and appearance after months in storage, including under accelerated conditions.

Our direct collaborations with toothpaste makers often result in close technical partnerships, where we help adapt mixing, hydration, and dosing processes to maximize cleaning activity while minimizing dusting or incomplete wet-outs. In our own labs, we have seen that even slight process tweaks—from hydration temperature to agitation time—lead to measurable differences in finished paste quality. By providing clear process recommendations, we help our customers run smoother production with fewer off-spec batches.

ZEODENT 623 and the Demand for Sensory Quality

Modern toothpaste buyers are sensitive not just to cleaning, but also to mouthfeel, flow, and consistency. Any chalky, gritty, or hard-to-extrude paste can damage a brand’s reputation overnight. In blind user panels with leading consumer brands, toothpaste containing ZEODENT 623 tends to score higher for perceived smoothness and reduced specking. The silica’s clean, white color also helps brands maintain color and opacity without unwanted yellowing or dark flecks—issues that sometimes crop up with less controlled silicas.

Negative feedback about texture is hard to recover from, so many of our clients run ZEODENT 623 through their own in-house extrusion and sensory panels before scaling up. To date, we find few complaints about “grit” or “unevenness” when formulators stick to our suggested dosing ranges and hydration protocols.

One important point is ease of blending. Formulators working with ZEODENT 623 consistently report good compatibility with common toothpaste gelling agents, humectants, and surfactants. In our experience, it integrates well with sorbitol, glycerin, sodium carboxymethylcellulose, and hydrated silica blends, offering flexibility for both high-water and low-water pastes.

Consistency Across Batches: What Sets It Apart

We see firsthand how minor fluctuations in a raw material can disrupt bulk transportation, plant cleaning schedules, or filling operations. ZEODENT 623’s manufacturing process uses advanced control systems that monitor critical parameters such as pH, temperature, and agitation. This hands-on attention minimizes lot variability, so one batch behaves just like the last. Soap makers and toothpaste formulators who manage dozens of ingredients look for partners who don’t create extra headaches—and most of our clients have stuck with this grade for years as a result.

Quality audits from multinational personal care brands push us to keep standards high—whether that’s through GMP-compliant production lines, risk-based batch releases, or traceability systems spanning from raw sand to finished pallet. Our technical service teams often walk the line with customers through pilot batches, addressing processing tweaks, regulatory questions, or logistics challenges as they arise.

Environmental consistency matters, too. Because ZEODENT 623 is made with attention to water usage, energy recovery, and waste remediation, it fits with suppliers demanding traceable, responsible sourcing. No material is perfect, but we believe that by scrutinizing everything from energy inputs to finished packaging, we’re doing our part to support responsible supply chains—a requirement from both major CPG brands and smaller ethical startups.

How ZEODENT 623 Differs from Other Grades

Not every cleaning silica is made for the same job. You find some grades optimized for high-clarity gels, some for premium polish, and a few for specialty low-abrasive market segments. ZEODENT 623 stands apart as a general-purpose, mid-range cleaning silica with an emphasis on reliable, repeatable performance in opaque and semi-opaque pastes.

Compared to ZEODENT 113 or similar high-structure silicas, ZEODENT 623 typically delivers less thickening effect, focusing on cleaning rather than viscosity build. For formulators using sodium carboxymethylcellulose, this often results in easier handling and lower risk of overdosed, “roping” paste.

Against lower-structure cleaning grades, ZEODENT 623 holds a tighter particle size distribution, which reduces the risk of “biting” particles that users can feel. We’ve taken feedback from tube-filling lines and retail surveys: consumers, especially in sensitive and children’s toothpaste, reject anything that feels rough, and our tighter controls help customers avoid costly complaints or returns.

Unlike high-performance polish grades designed for whitening formulas, ZEODENT 623 supplies steady, day-to-day cleaning without boosting total RDA out of regulatory comfort zones. It gives formulators flexibility to combine it with specialty grade silicas for blend formulations—a frequent practice in our larger clients’ product lines.

One more difference: ZEODENT 623’s dust generation is notably lower in plant conditions compared to some lower-bulk density grades. Several plant managers have told us that dust management and environmental controls simplified after switching, which means improved staff safety and less housekeeping.

Health and Safety: Built Into Every Batch

Silica production means staying laser-focused on worker safety, environmental releases, and consumer impact. We build safety into the process at every stage—starting with raw sand selection, through controlled precipitation, to dust containment on the packaging floor. Respirable silica risk is managed through strict exposure controls, personal protective equipment for team members, and real-time air monitoring.

Customers want peace of mind about the origin and handling of silica—especially after public media attention on crystalline silica’s risks. ZEODENT 623 comes as an amorphous, non-crystalline precipitated silica, tested batch-wise and confirmed with XRD and FTIR in our labs. We go beyond cosmetic regulation limits for lead and arsenic, making sure our ingredient is safe in everyday exposure scenarios.

Packaging is designed for safe, easy handling in food and hygiene production sites. Our packaging solutions include PE-lined bags and FIBCs with clear batch coding and full traceability. Product safety data sheets and transport documents reflect years of regulatory updates and practical shipping experience across continents.

Sustainability and Social Responsibility

Some of the world’s largest consumer product companies have set high bars for environmental and social responsibility, and every batch of ZEODENT 623 reflects those expectations. We source raw materials from audited, responsible mining operations and work to close water and energy loops inside the plant. In internal life-cycle assessments, we have identified bottlenecks—such as drying energy or water recycling capacity—and worked methodically to address them year by year.

Many toothpaste brands now want validated supply chains, so we maintain robust audit trails, support customer sustainability surveys, and work with local authorities on emissions and waste handling compliance. At the plant level, workers are trained to monitor emissions points, chemical handling, and recycling streams, so the silica inside toothpaste tubes around the world brings with it a foundation of responsible production.

Our R&D team continues to trial new low-temperature drying options and optimized agitation sequences to trim energy demand. By keeping a close connection with industry initiatives, and participating in both regional and global chemical stewardship programs, we stay aligned with ongoing shifts in environmental, social, and governance (ESG) requirements.

Supporting Product Innovation for Toothpaste Makers

Every year brings new trends in toothpaste: natural claims, lower abrasivity, specialty whitening, and more. ZEODENT 623 finds itself in both classic and inventive new formulas. We have worked with clients targeting fluoride-free, SLS-free, or natural-positioned pastes, and ZEODENT 623 adapts with minimal process changes.

Some formulators use superfine polishing silicas for whitening lines, but these can be prohibitively expensive for everyday cleaning pastes. ZEODENT 623 helps brands balance performance and margin. Our technical teams have supported transitions from conventional to “clean label” formulas, helping to select compatible gelling agents and adjust process water usage so that end products flow and tube just as smoothly as conventional versions.

A direct feedback loop from plant engineers, QA chemists, and marketing teams keeps our perspective grounded. If a production line starts to encounter foaming, clogging, or uneven mixing, our lab investigates and works with production supervisors, no matter which continent they’re on.

In the past five years, we’ve supported new launches in kids’ toothpastes, dual-phase pastes, and dental care tablets, each project bringing its own requirements. Thanks to its adaptable profile and safety record, ZEODENT 623 remains a dependable choice in both global and local brands.
