Niacinamide serum: what causes pilling, and how do you prevent it?

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.

• Pilling occurs when polymers like carbomers or silicones clash with niacinamide or other actives, leading to flaking upon application.
• In our factory, we prevent this by fine-tuning emulsification systems, adjusting pH levels, and using compatible thickeners such as xanthan gum to ensure phase stability.
• For UK market projects, typical MOQs start at 3000 units for standard 30ml bottles, which helps balance cost and efficiency.
• Sampling timelines are 3-4 weeks for initial prototypes, including compatibility and microbial hold-time checks to verify performance.
• We support full documentation for compliance, such as INCI lists, MSDS, and UKCA testing assistance, though final regulatory approval remains the client’s responsibility.
• Packaging options like airless pumps or dropper bottles are recommended to minimize oxidation and leakage risks during shipping.
• Lead time from order to shipment is 6-8 weeks, factoring in production batches and quality assurance steps like viscosity and fill temperature controls.
