Product Character — Practical Notes

What this structure means in practice

If you are weighing whether to switch to this material, compare three things: structural type, which decides what reactions it can join; polarity, which decides how it dissolves; and molecular weight, which decides how much to add. This product is an aliphatic organic carrying 6 oxygen, with mid-range polarity. Comparing these against your incumbent product gives a good first read on switching difficulty.

One practical note: ionic products absorb moisture once opened. If your usage rate is modest, smaller packs cost slightly more per kilo but avoid waste from caking.

When requesting a sample, check two things: whether it causes problems alongside oxidisable components in your current formulation, and how long it stays stable sealed at ambient temperature. The saturated aliphatic backbone is itself robust; risk usually comes from other components.

How it behaves in a formulation

Mid-range polarity; actual behaviour depends on the solvent and other components present. A small trial is the sensible confirmation.

On quantity: for standard grades, order two to three months of usage. Because ionic products pick up moisture, risk rises noticeably with time in storage, and that cost eventually lands in your purchase price. For intermediates and non-standard grades, trial a small order first and move to a volume price once the batch is proven.

Above 500 g/mol this is high-molecular-weight material that provides structure rather than dissolving. Before buying, check the degree of shear thinning and batch-to-batch consistency — both determine whether your finished product stays reproducible.

Storage and handling

On receipt and storage: keep the container tightly sealed — ionic products readily absorb moisture and cake; keep inorganic material away from strong acids and reducing agents; pre-disperse high-molecular-weight material, as adding it dry into a viscous medium clumps; specific handling and PPE follow the MSDS issued with the batch.. We accept against the batch COA by default. If you have an internal acceptance specification — assay, moisture, particle size, colour difference — send it over and we will issue the report against your standard.

One more point: if you need a retained sample, we can include one from the same batch with the shipment. That way, when a later batch arrives, you can compare it against your retained reference instead of relying only on the new COA, which shows more clearly how stable the product is batch to batch.

Purchase Profile

What this product is

Aluminium stearate is an inorganic compound with CAS registry number 637-12-7 and molecular formula C54H105AlO6 (molecular weight 877.4), belonging to the inorganic chemicals segment of chemical raw materials.

This entry sits in our inorganic chemicals range, which we hold as a stocking category rather than as a made-to-order one. Most enquiries in this group are repeat business once a grade is approved, which is why we keep batch records on file: a later order can be quoted against the same specification and compared directly with what you received before.

Jinan Shenghe Chemical Co., Ltd. supplies Aluminium stearate with stable inventory and provides a Certificate of Analysis (COA) with each batch; custom repacking is available per process requirement.

Identification

CAS number: 637-12-7 — searchable in PubChem for physicochemical, safety and regulatory data.

Its molecular formula C54H105AlO6 comprises 54 C, 105 H, 1 Al, 6 O atoms.

Also known as: Aluminium stearate

Category: inorganic chemicals

Applications in practice

Within the inorganic chemicals group, buyers usually arrive with an end product in mind rather than with a compound name. The practical questions are which grade fits the process, how much lead time the quantity needs, and whether the specification can be adjusted without changing the recipe. Send us the end product and we will answer all three in one quotation.

A practical note for repeat ordering: once a batch is approved, we can quote against the same specification so that subsequent orders are directly comparable. If your process changed in the meantime, tell us — the comparison is only valid within one specification.

Specification and acceptance

Purity on offer is per batch COA (not published) and packing is per order / batch confirmation (not published). Both are agreed before the order is placed rather than fixed on this page. We accept against the batch COA by default; if your QA has its own acceptance specification, send it and we will issue the report against your standard. Retained samples from the shipped batch can be included on request, which makes a later comparison against a new batch much more meaningful than reading a fresh COA on its own.

Ordering and supply

Supplier: Jinan Shenghe Chemical Co., Ltd.. Samples can be arranged before a volume order so you can qualify the material on your own equipment rather than on a certificate. Lead time depends on stock and quantity, and it is confirmed in the quotation rather than promised here. Payment can be made by bank transfer with a VAT special invoice issued; within Shandong and neighbouring provinces we can arrange fast delivery, elsewhere the goods move by road or rail at normal logistics speed.
