MATCHING STEPS
We line cosmetic ingredient mill replies against one CAS, assay, impurity, drum and SDS/TDS/CoA grid. Cosmetic Ingredient Sourcing is a buyer-side matching desk, not a plant or authorized house. A mill’s capacity is treated as unknown until that mill answers the same brief.
Each card is a line the mill must answer for the quoted cosmetic ingredient. Blank or “typical catalog” replies stay visible so they are not scored as confirmed facts. Public chemical listings reviewed on 2026-10-19 supplied question wording only.
Chemical name, INCI if used, CAS number, physical form and whether a substitute grade needs a separate row. Distributors, industrial procurement teams and formulators often start with different naming habits; the sheet still needs one identity.
Assay method, purity or concentration, moisture, residual solvents, trace metals and impurity profile. A cosmetic-grade typical assay is not interchangeable with a documented pharmaceutical-intermediate assay without buyer approval.
Current SDS, TDS and CoA format for the quoted product. TSCA status for US supply, REACH statements, GMP evidence or ISO quality-system files are requested from the named supplier and bound to the lot, not to this website.
Package size, net kilos, palletization, labeling language, storage range, requested timing and US destination. DOT or IMDG class is confirmed against the exact SDS after a product is proposed.
The safety data sheet for the quoted concentration is a verification file. This site does not provide mixing, dilution or hazardous-use instructions. Final handling follows that SDS, professional review and destination rules.
A technical data sheet describes typical properties. A certificate of analysis describes a lot. Comparing a TDS from one mill with a CoA from another mill without mapping methods is a common mismatch.
A document for a related grade, another manufacturer or a previous year is not evidence for the quoted product. Ask the supplier to state the document revision and the product code it covers.
Define whether a sample is meant to confirm identity, appearance, assay, odor, compatibility or packaging. Record the reviewer and pass/fail rule outside the commercial quotation.
Send INCI or CAS, assay method, kilo ladder and US plant even when some cells still read “open for mill confirmation.” Optional currency, per-kilo or whole-order budget, and a high-end, mid-range, cheaper or undecided mill preference frame trade-offs; they are not ratings this desk has verified.
