Anti-settling Agent CAS No
Quick answer: there is no single CAS number for every anti-settling agent. “Anti-settling agent” describes a function—keeping pigments, fillers, or other suspended solids from forming sediment—not one chemical substance. Products sold for this function can be organophilic clay, silica-based material, wax-derived rheology additive, modified urea, a polymeric additive, or a formulated mixture. The correct CAS number must therefore be taken from the current Safety Data Sheet for the exact product and supplier, not from the functional name alone.
For the Camp-Shinning organophilic clay covered by the supplied company SDS, the product form is identified as a mixture. Section 3 lists Alkyl Quaternary Ammonium Bentonite, CAS No. 68153-34-4, as the principal ingredient at 97% or more and quartz, CAS No. 14808-60-7, at 3% or less. The same composition section identifies the quaternary-ammonium surface treatment agent under CAS No. 61788-78-1. These numbers apply to that documented material; they are not universal identifiers for every product marketed as an anti-settling agent.
Why “Anti-settling Agent” Does Not Have One Universal CAS Number
A CAS Registry Number identifies a specific substance or defined chemical identity. An anti-settling agent, by contrast, is selected for what it does in a formulation. Different material families can perform the same suspension function through different mechanisms, and commercial products may be single substances, surface-treated solids, solutions, dispersions, or mixtures.
| Term on a search, RFQ, or product page | What it actually tells you | Can it determine one CAS number? |
|---|---|---|
| Anti-settling agent | The required function: reducing sedimentation or hard settling in a liquid formulation. | No. It is a functional category. |
| Rheology modifier or thixotropic additive | A broader performance category related to flow, structure at rest, shear response, and recovery. | No. Many chemistries fit the description. |
| Organoclay or organophilic clay | A material family based on organically modified clay. | Not by name alone. Confirm the exact product SDS. |
| Product trade name or model | A supplier-specific commercial identity. | It can lead to the correct SDS, but the SDS remains the verification source. |
| Mixture | The commercial material contains more than one reportable component or is documented as a formulated product. | It may have several component CAS numbers rather than one product-level number. |
This distinction explains why a web search can return a blank CAS field, several different numbers, or a number that belongs only to one component. It does not necessarily mean the supplier’s documentation is wrong. It usually means the search phrase is too broad to establish chemical identity.
The Verified CAS Information for Camp-Shinning Organophilic Clay
When the requested anti-settling technology is Camp-Shinning organophilic clay, use the current SDS for the selected material. The supplied company SDS provides the following composition references:
| SDS entry | CAS number | Documented proportion or role | How to use the information |
|---|---|---|---|
| Alkyl Quaternary Ammonium Bentonite | 68153-34-4 | 97% or more; principal ingredient | Use as the main chemical identity only when the exact supplied SDS applies to the product being purchased. |
| Quartz (SiO₂) | 14808-60-7 | 3% or less | Keep this component visible in safety and compliance review; do not replace the main ingredient CAS with it. |
| Quaternary ammonium surface treatment agent | 61788-78-1 | Identified in the composition description | Treat it as a component or treatment reference stated by the SDS, not as a universal CAS for organoclay. |
| Product form | Not applicable | Mixture | Expect the SDS to describe the commercial product through its component identities. |
The composition table is more reliable than an unqualified number copied from a marketplace listing, search snippet, old quotation, or another supplier’s document. If the selected grade, manufacturing source, or SDS revision changes, repeat the verification before using the number in purchasing, regulatory, or shipping records.
How to Verify the Correct CAS Number Before You Buy
- Identify the exact commercial product. Record the supplier, product name, grade or model, and intended application. A request that says only “anti-settling agent” is not specific enough.
- Request the current SDS. Confirm that the product identifier in Section 1 matches the quotation, label, and sample. Check the revision date and the market or language version supplied.
- Read the composition section. Section 3 shows whether the product is treated as a substance or mixture and lists reportable component identities. Do not assume the first visible CAS number describes the whole commercial product.
- Compare supporting documents. Check that the TDS, quotation, sample label, COA, and SDS refer to the same product name or model. A document set assembled from different grades can create a false mismatch.
- Confirm the purpose of the number. A purchasing database, customer declaration, customs form, chemical inventory review, and workplace SDS system may ask different questions. Establish whether the requester needs the principal ingredient, every reportable component, or a product-level identifier.
- Resolve discrepancies before shipment. If the CAS, chemical name, product name, or supplier identity differs across documents, stop using the unverified number and ask the supplier for written clarification.
If you are still defining the material rather than checking a document set, start with the existing guide to anti settling agent. For the material category used in Camp-Shinning’s documented SDS, review the organoclay overview.
CAS Number Troubleshooting Table
| Problem | Likely reason | Corrective action |
|---|---|---|
| A chemical database shows no CAS number for “anti-settling agent.” | The search term describes a function rather than a defined substance. | Search by the exact product and chemical identity, then verify it against the supplier SDS. |
| Two suppliers give different CAS numbers. | The products may use different chemistries, carriers, surface treatments, or mixture definitions. | Do not force them into one identity. Compare each current SDS and confirm whether the products are genuinely equivalent. |
| The product page and SDS use different names. | The product page may use a functional marketing description while the SDS uses a chemical or regulatory identity. | Match both documents through the exact trade name, model, supplier, and revision. Ask for written confirmation if the connection is unclear. |
| The SDS says “mixture,” but the purchasing system accepts only one CAS field. | The purchasing system may be asking for a principal component even though the commercial product contains multiple listed components. | Ask the responsible compliance team which identifier and supporting note are required. Do not omit component information from the SDS. |
| A quotation contains a CAS number but no SDS. | The number may have been copied from a generic category, an old document, or a different grade. | Request the current SDS before approving the vendor or completing regulated documentation. |
| The COA does not show a CAS number. | A COA reports batch quality results; it is not necessarily the primary chemical-identity document. | Use the SDS for identity and safety information, then use the COA to confirm the batch and tested quality fields. |
| An old SDS and a new SDS do not match. | The product composition, classification, regulatory format, or document revision may have changed. | Confirm which revision applies to the supplied lot and destination market. Retire the obsolete document only through the buyer’s controlled document process. |
Do Not Diagnose Settling Performance from the CAS Number
A CAS number confirms chemical identity; it does not prove that an additive will solve a settling problem in a particular formulation. Suspension performance also depends on the liquid phase, solids, particle characteristics, dispersion quality, addition sequence, shear history, and the flow structure required at rest and during application.
Two materials can be described by related chemical identities yet behave differently because their grade design and processing requirements are not identical. Conversely, different chemical families can all be sold as anti-settling agents while requiring different incorporation methods and serving different formulation systems. Product selection therefore needs both identity verification and formulation testing.
If the immediate issue is poor suspension, low viscosity, incomplete dispersion, or loss of structure, first separate that formulation problem from the identity check and use the broader anti-settling agent troubleshooting guide. The CAS number can help confirm what material was supplied, but the corrective action must be based on the formulation, dispersion process, and verified product guidance.
Information to Send When CAS Documents Do Not Match
A supplier can resolve an identity question faster when the request includes the complete document context. Send:
- supplier name and product trade name;
- grade or model number;
- SDS title, language, market version, and revision date;
- the CAS number and chemical name shown in each conflicting document;
- quotation number, purchase order, or sample label reference;
- lot or batch number when material has already been supplied;
- destination country and the party requesting the information;
- the intended use of the number, such as supplier approval, workplace records, chemical inventory review, or shipping documentation.
Do not send only a screenshot of a search result. The technical or compliance reviewer needs the product and document identifiers to determine whether the issue is a genuine composition conflict, a mixture-versus-component misunderstanding, or a mismatch between grades.
