An azelaic serum brief begins with ingredient identity. Free azelaic acid and potassium azeloyl diglycinate (PAD) are different ingredients. Select the exact INCI, concentration basis, formula partners and finished pack before comparing OEM/ODM quotations.
Compare the ingredient routes
| Field | Free azelaic acid | Azelaic derivative such as PAD |
|---|---|---|
| Identity | Specify azelaic acid on the approved formula | Specify potassium azeloyl diglycinate or the exact selected derivative |
| Use level | State the concentration and raw-material specification | State the addition rate and active-content basis; do not treat it as a free-acid percentage |
| Formulation | Review vehicle, dispersion or solubilisation, pH and stability | Review compatibility, pH, formula partners and stability for this ingredient |
| Evidence | Claims and final-pack performance require evidence for the selected formula; one ingredient or percentage does not establish universal suitability | |
YANSE COS serum development and filling
YANSE COS formulates and fills private-label topical serum projects at its Fujian factory. Niacinamide and other formula partners are specified separately. This guide describes how to prepare a project brief; it does not establish a standard concentration, stock formulation, dispatch date or performance guarantee.
YANSE COS serum MOQ is 3,000 bottles per standard SKU and 5,000 bottles for custom formula projects. The bottle is the order unit; fill volume, container, closure and decoration are agreed in the quotation. Airless components, special packaging and multi-component ampoule projects may have separate minimums.

Separate a development direction from an approved claim
Terms such as non-comedogenic, suitable for sensitive skin, low-irritation or oil-control require evidence appropriate to the selected finished formula and intended use. A market trend, ingredient name or prototype description does not establish those properties. Review classification and claims for the destination market before artwork approval.
Qualify the manufacturer and the SKU
Review the named holder, factory site, scope and validity of published factory certificate copies. Separately agree the approved formula/INCI, raw-material identity, batch CoA, microbiology, preservative efficacy, stability and final-pack compatibility records to be reviewed for your serum. Availability is confirmed during project qualification.
Request an ingredient and packaging review
Send the exact ingredient or route you want to investigate, intended claims, pack and quantity. The OEM team confirms feasibility, sample availability and the quotation.

Is PAD the same as free azelaic acid?
No. Potassium azeloyl diglycinate (PAD) is an azelaic derivative. Ingredient identity and concentration basis must be stated separately.
Does this guide specify a ready-to-order azelaic concentration?
No universal concentration or ready formula is established here. The approved ingredient, use level, formula readiness and sample schedule are confirmed for each project.
What is the MOQ for an azelaic serum project?
YANSE COS serum MOQ is 3,000 bottles per standard SKU and 5,000 bottles for custom formula projects. The bottle is the order unit; fill volume, container, closure and decoration are agreed in the quotation. Airless components, special packaging and multi-component ampoule projects may have separate minimums.
