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.

  • When targeting EU retail and e-commerce, comprehensive stability testing is essential for regulatory compliance and market acceptance.
  • Recommended tests involve accelerated stability studies at elevated temperatures like 40°C for 3-6 months to predict shelf life, along with real-time testing under normal conditions for up to 24 months to monitor pH, viscosity, and microbial stability.
  • At LAEYO Labs, we assist clients with this process by providing guidance on test parameters and documentation.
  • For MOQ, hair care products often start at 5,000 units, with sampling timelines of 2-4 weeks for prototypes.
  • Required documents include stability reports, safety assessments, and EU-compliant labeling such as INCI lists.
  • Packaging must be validated for compatibility to prevent leakage or ingredient degradation during transit.
  • Lead time from sampling to production typically ranges from 8-12 weeks, depending on test outcomes and reformulation needs.
  • We support all necessary testing and documentation to help meet EU standards, but final regulatory approval rests with the brand.
