Check source documents and specification, inspect appearance and basic indices by category.

Formulas are tuned in the lab and problems are prevented on the line. Our in-house lab and QC room handle development, sampling and routine testing, so every batch carries a record.
The same category requires different formulas for different brand positions. We first clarify your target price, target audience and core selling point, then determine the formula system — rather than applying an existing formula directly to your brief.
Quality control does not end with a final spot check. Materials, process, finished goods and stability each cover a distinct stage; weakening any one of them surfaces at a later stage.
Check source documents and specification, inspect appearance and basic indices by category.
Routine patrol on key stages such as emulsifying and filling — recording temperature, appearance and fill volume.
Routine microbiological and physico-chemical testing against the product standard; release only when passed.
Stability observation on development samples, informing shelf life and formula freeze.
Test items are determined by product category and target market; ask us for the specific list.
Subject, scope and validity follow the originals. Before cooperating, ask us for clear copies for verification.
