JY-DM100 Dimethyl Silicone Oil is listed by Juyou under the methyl silicone oil series for personal care formulation work, including sensory, film-forming, emulsion, silicone oil and elastomer applications. For an overseas buyer, the grade name is only the starting point. The procurement record should confirm the usable viscosity window, the target formulation role and the documents needed before sample approval or bulk ordering.
Why the viscosity window needs written confirmation
The accessible Juyou product page identifies JY-DM100 as a dimethyl silicone oil grade and points buyers to the related TDS and MSDS documents. It does not replace current lot documentation, and it should not be used by itself to approve a formula change. Before scale-up, buyers should ask Juyou to confirm the current specification, test method and tolerance used for the supplied lot.
This is especially important when the material is used as a carrier, sensory modifier, film-forming support or silicone phase component. A small change in flow behavior can affect metering, dispersion, filling, package compatibility and the final skin or hair feel. The purchasing team should keep these checks in the same file as the quotation and sample approval record.
Records to keep before sample approval
| Record | Procurement use |
|---|---|
| Current TDS and SDS | Confirms the exact grade identity, document version and safety information used for internal approval. |
| Viscosity method and acceptance range | Prevents comparing results from different methods, temperatures or units. |
| Formula role | Separates use as a carrier, sensory oil, silicone phase modifier or blend component. |
| Sample-to-bulk traceability | Links the evaluated sample, quotation, lot number and received drum labels. |
Application checks for the buyer’s laboratory
- Blend JY-DM100 into the intended formula at the target and boundary dosage levels approved by the formulator.
- Record mixing order, temperature, shear, hold time and any visible separation after storage.
- Compare dispensing behavior from the buyer’s actual pump, filling needle or packaging format.
- Keep a reference sample from the approved lot so incoming bulk shipments can be compared without relying on memory.
Questions to send with the RFQ
Include the intended product type, required document set, target annual volume, sample quantity, package size, destination, viscosity confirmation needs and any restricted-substance or customer-standard requirements. If the formula already uses another dimethyl silicone oil, include the incumbent grade and the reason for replacement. Unknown certification, performance and regulatory fields should remain pending until Juyou provides current documents.
Frequently asked questions
Can the product code alone confirm the final viscosity specification?
No. The code helps identify the intended grade, but purchasing approval should rely on the current TDS, lot documents and agreed test method from the supplier.
Is this article a claim that JY-DM100 will work in every personal care formula?
No. It is a procurement checklist based on the accessible Juyou product source. Formula compatibility, sensory performance and package behavior must be checked in the buyer’s own system.
