Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

  • Our fragrance control starts with GC-MS fingerprinting of every fragrance batch before production.
  • We maintain a master reference profile for each scent and compare every incoming batch against this standard.
  • For hair care formulations, we blend fragrances in temperature-controlled rooms (22±2°C) with automated mixing to ensure uniform dispersion.
  • Each production batch undergoes headspace GC analysis to verify fragrance concentration within ±2% of target.
  • We provide full documentation including GC chromatograms and batch traceability reports for your quality assurance records.
  • For US private label clients, we recommend a minimum order of 1,000 units per SKU to maintain batch consistency, with sampling lead time of 10-14 days including fragrance verification testing.
