Before buying raw materials for a trial, first establish which material is being discussed and what information is already available.
Pre-purchase checklist
- Material identity.
- Product specifications or technical information.
- Grade or intended application, only when actually documented.
- Availability of a COA or other documents, where relevant.
- The packaging offered.
- Supplier or manufacturer identity.
- Available storage information or other documentation.
Price is not the only basis for comparison
Price matters, but buying solely on price or product name can cause confusion when grades, specifications, sources or packaging differ.
Before a trial, make sure you understand the material being purchased, its specifications and the context of its use.
The availability of a COA does not in itself guarantee material suitability, and this article does not state regulatory approval.

Specifications (Product Data): ensure specifications match your formula requirements. COA (Certificate of Analysis): check the analysis certificate to confirm quality. Regulatory compliance: ensure the material meets applicable cosmetic regulations. Packaging and storage: check packaging, shelf life and storage method. Trusted supplier: choose a consistent, responsive and trustworthy supplier.
