Application to RFQ
Personal care ingredient suppliers mapped from use to purchase fields
A use case is not a specification. This page turns formulation, processing and distribution context into CAS, assay, packaging and document questions for personal care ingredient suppliers. Suitability, inventory and mill capability are not assumed from the family name Pharma Intermediates & Fine Chemicals.
- INCI / chemical name recorded
- Assay method named or marked open
- SDS / CoA requested for the quoted product
Application and specification matrix
Rows are buyer contexts. Columns are purchase fields. Empty cells stay empty until the buyer or a named mill fills them. Public product-family pages inspected on 2026-10-19 are used only to frame these questions.
| Buyer context | Identity fields | Assay / impurity | Package / destination | Open documents |
|---|---|---|---|---|
| Personal-care formulation | INCI, CAS, physical form, carrier | Assay, odor, color, residual solvents | Kilos, drums or bottles, US plant | SDS, TDS, allergen or impurity questions |
| Fine-chemical processing | CAS, grade, particle size if solid | Assay method, moisture, trace metals | Drums or IBCs, hazardous class open | CoA format, process-aid statement |
| Distribution / import | Commercial name vs CAS mapping | Lot CoA vs catalog typical | Pallet, labeling language, Incoterm | TSCA question, transport classification |
| Sample / trial lot | Same identity as intended production | What the sample is meant to prove | Sample grams vs production kilos | Sample SDS, retain sample policy |
Grade language trade-off
Buyers sometimes ask for cosmetic grade while a mill answers with a pharmaceutical-intermediate assay package, or the reverse. Those labels are not interchangeable without a method, impurity profile and intended-use review. This desk records both the requested label and the quoted label instead of collapsing them. Active content, molecular weight and particle size are requested only when the process uses them.
Limits that stay with the buyer
Application fit, skin-contact claims, drug-intermediate status, storage and transport all depend on the exact concentration, SDS and professional review. This page does not instruct mixing or hazardous use. Flash point, density, viscosity and pH remain supplier questions bound to the quoted lot. A related-grade SDS is not evidence for the quoted personal care ingredient.
Documents suppliers should attach to a use-case quote
- Does a formulation brief replace CAS?
- No. For a lotion is not an identity. Keep CAS or a documented synonym on the RFQ even when INCI is the working name for personal care ingredient suppliers.
- Can GMP evidence be borrowed from another product family?
- No. GMP, ISO or REACH statements must be requested for the quoted product and site. This website does not hold those certificates.
- When is transport class known?
- After a named product and concentration exist. Until then, keep UN number and DOT or IMDG class as open supplier questions bound to the SDS.
Translate the use into a purchase brief
Describe lotion, processing or import context, then add CAS, assay, pack net and SDS questions. A use case does not prove that a mill already stocks the personal care ingredient.
