APPLICATION TO RFQ
Cosmetic ingredient manufacturers mapped from use to purchase fields
A lotion or processing note is not a purchase identity. This matrix turns personal-care, fine-chemical and import context into CAS, assay, drum and SDS questions aimed at cosmetic ingredient manufacturers. Application fit is left unclaimed until a named lot exists.
- INCI / chemical name recorded
- Assay method named or marked open
- SDS / CoA requested for the quoted product
Application and specification matrix
Rows are US buyer contexts. Columns are purchase fields for the quoted cosmetic ingredient. Empty cells stay empty until the buyer or a named manufacturer fills them. Product-family pages inspected on 2026-10-19 frame the questions; they do not prove mill access.
| 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.
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 are requested only when the process actually uses them.
Documents manufacturers 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.
- 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/IMDG class as open supplier questions bound to the SDS.
Translate the use into a purchase brief
Name the formulation or process context, then INCI, assay method, kilos and destination. We will not infer warehouse stock or mill capability from the use case alone.
